One More Mild Day; Old Man Winter Is Knocking On The Door…

Screen Shot 2017-01-24 at 9.49.46 PMHighlights:

  • Hold on to your hats
  • Cold air returns
  • Extended period of scattered snow showers; squall potential

Changes Brewing…Wednesday will feature more of the same mild weather we’ve come to know and enjoy across the Mid West over the past couple of weeks.  Despite the mild air, a storm system will result in scattered showers for our hump day, along with very windy conditions.  Gusts of 40 MPH will be common across central IN.

Temperatures will fall late Wednesday and Old Man Winter is set to make up for lost time as we progress through the back half of the work week and on into the weekend.  In addition, fast-moving upper level energy will push southeast in the active northwest flow aloft.  Scattered snow showers will result, along with localized embedded heavier squalls.  It certainly won’t snow the entire time, but passing snow showers will be a good bet from time to time Thursday through Sunday.

Our wintry pattern will relax briefly early next week, but renewed cold air appears poised to blow into town the middle of next week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Dusting – 1″ (local 2″ amounts possible)
  • Rainfall: 0.10″ – 0.25″

Foggy Start; Winter Returns…

Screen Shot 2017-01-23 at 7.15.25 AMHighlights:

  • Dense fog this morning
  • Turning much colder this week
  • Scattered snow showers late week

Low Beams On…Dense fog engulfs most of central IN this morning.  Make sure you have the low beams on this morning as you head off to work and school and allow extra time.  A shower is possible at any point today, but particularly across the eastern half of the state.

Our next storm system will push through mid week.  Southwest winds will increase Wednesday and scattered showers will accompany a cold front moving through the state.  Temperatures will fall Wednesday night into Thursday and scattered snow showers will develop.

The theme late in the week and for the weekend will be a wintry one.  Upper level energy will interact with the colder conditions and result in scattered snow showers from time to time into the weekend.  The active northwest flow will remain into next week, as well, and we’ll have to keep a close eye for the prospects of a more “robust” clipper impacting the region just beyond this forecast period.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Dusting – 1″
  • Rainfall: 0.10″ – 0.25″

Spring-Like Weekend, But Changes Loom…

Screen Shot 2017-01-20 at 10.25.29 PMHighlights:

  • Spring-like weekend
  • Unsettled times continue
  • Winter returns

Rare January White Leg Alert…The big news this weekend will be temperatures close to 30 degrees above normal and a legitimate spring feel.  Average highs across central IN this time of year are in the middle 30s and temperatures this afternoon will zoom to the lower-middle 60s.  Patchy morning fog and drizzle will be with us, but we’re remaining optimistic we could squeeze a couple of looks at the sun during the day.  Count yourself lucky if you do, indeed, see that weird giant bright thing in the sky! 😉

A developing storm system will track east across the central Plains and into the TN Valley this weekend.  This will result in a significant severe weather outbreak across the south and increasing rain chances here for the back half of the weekend.  The magnitude of the rain and potential embedded storms remains in question, but shower chances will at least be on the increase Sunday afternoon into the evening.  We note short-term, higher resolution modeling hitting the locally heavy rain threat harder than global data early this morning (centered on Sunday evening) and we’ll keep a close eye on things as most central IN communities remain waterlogged.  Winds will increase Monday- NE shifting to the N and gusts to 40 MPH with leftover showers continuing.

Tuesday will present a bit of a break in our active pattern before a fast-moving cold front blows into town Wednesday with scattered showers amidst blustery conditions.

We turn colder (you knew this incredibly mild pattern had to break at some point) late week and upper level energy will help ignite snow showers with the return of the wintry feel Thursday into Friday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Dusting – 1″
  • Rainfall: 0.50″ – 0.75″

Times Are Changing, Or Are They?

January-to-date is running milder than normal across the region- to the tune of 3.3 degrees (F).  This is after a frigid open to the month, as you recall.

conus_mtd_t2max_anom_2017The second week of the month warmed significantly and continues, overall, for the next week.

ncep_cfsr_noram_t2m_week_anomThe mid-January warmth is attributed to a roaring PAC jet which is currently helping flood the country with temperatures much more like spring than the dead of winter.  We continue to forecast 60+ this weekend across central IN.

Winter lovers, have no fear as changes appear to be in the offing as we go through the last few days of January and head into February.  The winter so far has featured conflicting signals that continue to try and compete with one another to take hold of the pattern.  Can we get these drivers to align in a way that would pull a more persistent trough into the east for the second half of the winter and, ultimately, set-up a sustained cold pattern helping make up for lost time in the snowfall department?  Time will tell, but we do note the following late month:

  • (+) PNA pattern
  • Sudden stratospheric warming event
  • High latitude blocking

All are encouraging for a shift back towards a wintry regime.  As always, the devil is in the details and we’re skeptical as to the longevity of these signals.  “Cautiously optimistic” would be the way to sum up our current feel longer-term into the month of February, but we’re not as bullish on lock and hold cold, wintry conditions at this time as what you may hear from some of our national compadres.  Understanding that various drivers can have a different impact mid and late winter as opposed to early is one thing.  It’s also important to note that long term modeling has been abysmal as of late and we want to tread through the next couple of weeks with caution to see whether or not the cold drivers can finally take hold.

Needless to say, at least through late month, one can see the significant changes take place at 500mb.

Thursday:

ecm_eps_z500a_noram_2This Weekend:

ecm_eps_z500a_noram_9Next Weekend:

ecm_eps_z500a_noram_11The pattern begins in the short-term with a look that will power anomalous warmth through the weekend, along with renewed rain chances Thursday night into Friday (another 1″+ for most), but begins to shift next week towards the colder look.  The 2nd (weekend) storm system will be significant and poses a severe risk to the southeast region.  Modeling has backed away on the heavy rain threat Sunday, but showers will be around early next week along with very windy conditions (40+ MPH gusts).  Blocking is forcing the low south.  By the time we get to next weekend, the pattern has done a 180 and in a position to drill unseasonably cold air back into the central and eastern portions of the country.

As far as storms go later in the period, it’s far too early to discuss specifics, but the pattern seems to be one that will promote the chance to get into the act on high-ratio producing clippers.  It’s the first time we can say that this year.  Time will tell…

Warm, But Unsettled Week…

Screen Shot 2017-01-16 at 7.26.31 AMHighlights:

  • Unseasonably warm week
  • Multiple rounds of rain and embedded thunderstorms
  • Eyeing winter’s return next week

Have The Rain Gear Handy…While we’ll enjoy unseasonably mild temperatures, the wet and unsettled theme we’ve been dealing with as of late we’ll continue this week.

Most of the daytime today will feature more dry time than wet with just scattered showers expected before more widespread rain and embedded thunderstorms arrive by nightfall.  Wet and periodically stormy times continue tonight into the early morning hours Tuesday.  After a predawn high in the mid 50s, temperatures will slowly fall during the day Tuesday before remaining steady in the middle to upper 40s for the balance of the afternoon.

We may get a brief (rare) look at the sun Wednesday as we’ll be in between weather systems, but have no fear, as our next storm will be developing to our south and arrive with showers Thursday.  🙂  Rain and perhaps a thunderstorm continue Friday, especially through the first half of the day.

The majority of Saturday will feature dry and warm (early spring-like) conditions, but clouds will increase during the second half of the day and showers will push north into the state at night.  Windy, wet conditions continue Sunday.

Longer-term, forecast models continue to paint a significantly colder, wintry pattern as we go through the last week of the month.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″ – 2.00″

January Thaw For The New Week Ahead…

Screen Shot 2017-01-14 at 4.13.32 PMHighlights:

  • Damp, chilly Sunday
  • Milder week ahead
  • Spring-preview late next week

Improvements Coming…Most of tonight will feature dry conditions along with temperatures settling back below freezing (most of central IN will fall into the middle to upper 20s).  Another surge of light precipitation will arrive Sunday morning into the afternoon and this could begin as a period of freezing rain from the city and points north.  Similar to today, we don’t expect any major problems from the freezing rain and all of the region should warm above freezing during the afternoon.

While Monday could feature a quick-hitting shower at any given time, more widespread steady rain will push into central Indiana during the day Tuesday, along with breezy conditions.  Those breezy southwest winds will help give temperatures a boost into the middle 50s for afternoon highs.

We’ll shift that southwest wind around to the northwest Wednesday and this will help push cooler air into the state for mid week.  Despite the cooler feel, we’ll remain well above average with breezy conditions.  (Average highs in central Indiana are in the middle 30s this time of year).

The big news for the latter portion of the forecast period will be a true spring-like feel developing as we rumble into the weekend.  In fact, temperatures will surge well into the 60s next Saturday.  Modeling isn’t in total agreement on rain chances with a moist southwest flow in place.  We’ll take the “optimistic” route at this time and forecast a dry Saturday, understanding that we’ll have to maintain a close eye on things.

Quick heads up, longer term data continues to suggest we’ll flip into a much colder and stormy pattern as we wrap up January and head into February.  Winter is far from over…

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″

Prolonged Stretch Of Gloomy Weather…

screen-shot-2017-01-10-at-7-25-16-amHighlights:

  • Active stretch of weather begins
  • Moderating trend into midweek
  • Ice concerns Friday-Saturday

Sunglasses NOT Required…We’re entering the beginning of an active stretch of weather, with an extended period of overcast skies and gloomy conditions.  Let’s dive in and take the challenges one-by-one:

Showers develop this afternoon as a cold front moves into the state.  Ahead of the front, strong southwest winds will gust upwards of 45 MPH+.  A “big hair warning” is in effect.  🙂

A brief shot of colder air will arrive late tonight into Wednesday, but just as soon as it arrives, it’ll leave and temperatures will approach 60 Wednesday night as showers return.

Thursday will be a wet day with periods of rain and slowly falling temperatures during the afternoon/ evening.

Friday is much colder as the arctic front will be to our south, but most of the day looks dry.  Moisture will lift north Friday afternoon and evening and with cold air in place, the precipitation should take the form of a mixture of freezing rain and sleet.  Periods of freezing rain likely continue Saturday.  It’s far too early to discuss amounts and we also want to reiterate the difference of 1-2 degrees will mean a world of difference between areas dealing with ice versus a cold rain.  The “battle zone” looks to take place across central IN.  If you have travel plans Friday night and Saturday, please keep abreast of later forecasts and updates.

Regardless of whether or not we’re dealing with icy conditions across central IN during the first half of the weekend, temperatures will warm during the second half of the weekend and change any frozen/ freezing precipitation over to plain ole cold rain Sunday into Monday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″ – 2.00″

Busy Weather Week; Ice Storm Potential Friday Into The Weekend…

screen-shot-2017-01-09-at-7-26-23-amHighlights:

  • Late night light freezing rain develops
  • Milder and wet through mid week
  • Ice storm potential on the rise late week

Feeling Downright Balmy Out…Temperatures this morning (writing this at 7a) are running close to 20 degrees above where we were this exact time Sunday.  20 degrees has never felt so warm!  🙂  This moderating trend will continue into mid week, including temperatures that approach 60 Thursday.  That said, we have a mini “speed bump” to go over tonight and that’s the opportunity for light freezing rain late tonight into the wee morning hours Tuesday.  Temperatures should go above freezing just before the morning rush Tuesday, but plan to leave additional time as slick spots may remain.  Once we clear the “speed bump,” it’s off to the races in the temperature department through mid week: around 50 Tuesday afternoon and around 60 by Thursday (that’s a late night high Wednesday in the upper 50s).  Periods of showers will come with the milder air, centered on Tuesday and late Wednesday into Thursday.

Unfortunately, the milder times don’t last long and we still forecast “trouble” late in the week.  The set-up remains unchanged as a big, sprawling arctic high pushes into Wisconsin Friday.  This will help “shove” the arctic front through Indiana before stalling along the Ohio River Friday into Saturday.  As this is happening, ripples of energy will help ignite periods of precipitation Friday into the weekend.  With cold air locked in at the surface, we expect the potential of a rather prolonged period of freezing rain developing late Friday and continuing into the weekend.  We still have time for things to change, but from this distance, the predominant precipitation type, unfortunately, appears to be freezing rain.  Stay tuned as this could be a high impact event.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall:  0.00″
  • Rainfall:  1.50″ – 2.25″

Changeable Weather; Late Week Ice Threat…

screen-shot-2017-01-08-at-10-01-49-amHighlights:

  • Another bitter day
  • Moderating temperatures ahead
  • Late week ice threat looms

Bitter Cold Gives Way To Moderating Temperatures…The first half of the forecast period is easy, but we caution big time headaches loom and details are far from etched in stone once to the second half of this forecast period.

First thing’s first and that’s today.  Look for a continuation of bitterly cold air, but slow moderation will be noted this afternoon: Not AS bitter and lighter winds.  We may even crack the 20 degree mark!  I know, break out the swim suits, right?!  This moderating trend is setting the tone for a more significant jump in the mercury later in the week.  Before a “taste of spring” arrives, we’ll have to deal with a brief opportunity for freezing drizzle Monday evening.  Temperatures will zoom to around 50 Tuesday and around 60 for mid week.  Showers will be with us off and on- focused on Tuesday and Thursday for most widespread coverage.

Then comes the “fun.”  A strong, sprawling arctic high will push south into the northern Plains Friday.  At the same time, “resistance” from the southeast ridge (that can be thanked for the spring-like feel here Wednesday and Thursday) will result in the arctic front only slowly being able to push south.  Ripples of energy, or waves of low pressure, will move along the arctic boundary and result in periods of widespread precipitation Friday into the weekend.  As the cold, dense arctic air oozes south, we have concern for icing- freezing rain and sleet Friday into Saturday.  Depending on how things evolve, this may continue into Sunday, as well.  If you have travel plans this weekend, please keep a close eye on the developments in the forecast from Friday on.  Stay tuned.

Upcoming 7-Day Precipitation Forecast:

Snowfall: 1.00″

Rainfall: 1.50″ – 2.00″
