Stormy At Times…

Screen Shot 2016-06-19 at 10.28.38 PMHighlights:

  • Front arrives late Monday
  • Strong storms; heavy rain threat Wednesday
  • Unsettled pattern

Busy Week Ahead…The overall pattern features the mean ridge position across the Four Corners region and sets up an active NW flow for our part of the country.  It’s a pattern we need to get used to as it’ll remain intact to close the month and open July.  Challenges are present in regards to specifics with timing and track of thunderstorm complexes we’ll deal with this week, particularly Wednesday.

In the shorter term, a frontal boundary will slip into central IN Monday night and a broken band of thunderstorms will accompany it.  A few storms could reach strong to severe levels Monday evening.

Attention will then shift to Wednesday.  Ingredients are coming together to present both a severe component (damaging wind the biggest threat) and localized flash flood threat.  We’ll update our latest thinking Monday morning.

As we progress into late week, additional shower and thunderstorm complexes are possible, but we stress timing issues abound.  It’ll be a warm and humid end to the week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″-2.00″ (locally heavier totals)

Mostly Dry Weekend Before Storm Chances Return…

Screen Shot 2016-06-18 at 7.53.29 AMHighlights:

  • Mostly dry and hot weekend
  • Humidity levels on the rise Sunday
  • Storm chances return

Put On That Sunscreen…High pressure will supply a beautiful open to the weekend, including mostly sunny to partly cloudy skies, low humidity levels, and warm temperatures.

Our airflow will shift to the SW Sunday and help push a more humid air mass back into the state as the day progresses.  An isolated thunderstorm could accompany the return of the humid air, but for now we’ll maintain a mostly dry forecast.

Better thunderstorm chances arrive Monday evening into Tuesday as a cold front pushes in from the north.  A locally strong to severe storm is possible.  As we move forward into the middle and latter parts of next week, models suggest a rather unsettled time of things.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1″-2″

Video Update: Stormy For Some This Afternoon…

Do we rid the morning convection and cloudiness to allow strong to severe thunderstorms to develop this afternoon and evening?  This morning’s video has more.

Strong Storm Threat Wednesday…

Screen Shot 2016-06-14 at 9.27.06 PMHighlights:

  • Scattered strong-severe storm threat Wednesday
  • Drier close to the week
  • Next front arrives Monday PM

Keeping An Eye On Wednesday’s Storm Threat…Today’s rain numbers weren’t uniform in the least, but several neighborhoods picked up beneficial rains of over 1.5″.  Wednesday will also feature the threat of showers and thunderstorms (again, some with locally heavy downpours).  Some of these storms could also reach strong to severe levels during the afternoon/ evening, particularly if morning rain doesn’t “get in the way.”  We’ll watch data overnight and update accordingly come morning.

We’ll turn drier and slightly cooler to close the work week and head on into the weekend.  The heat will begin to crank again early next week, with highs around 90 Sunday and Monday.  Our next weather maker looks to arrive Monday evening as a cold front pushes in from the north.  We’ll feature shower and thunderstorm chances in our Monday PM forecast.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.50″-1.00 (locally heavier totals)

Some Thoughts Into Late June…

The first (12) days of June are in the books and we’re running drier and warmer than average, month-to-date.  Officially, IND reports a temperature departure of 3 degrees above normal and a rainfall deficit approaching 1″.

As we look ahead, the pattern is one that seems to favor the most sustained hot dome (mean ridge) position across the 4 Corners region and Southwest states.  This morning’s European ensemble data shows this well:

Ck1DCVXWsAEGcde.jpg-largeThe teleconnections aren’t much help in trying to generate longer term thoughts.  They would favor more of a “normal” period temperature-wise, locally.  (BTW, thanks to the fine folks at MAD US Weather and ESRL for the data below).

On another note, there are different times through the year when the respected positive and negative phases of the teleconnections below have more of an impact on our weather, particularly during the fall through spring months.

JuneTellesLooking at some of the model data, the general consensus is for a warm look to go through the back half of the month, but we caution that we can’t simply “broad brush” the forecast through the EOM as warm and relatively quiet (a note on that in a moment).

gem-ens_T2maMean_us_7

gfs-ens_T2maMean_us_7As mentioned above, despite an overall warm look on the models there will likely be periods of cooler “jabs” and it sure looks like a rather transient pattern to us across the Mid West and Ohio Valley, featuring more of the sustained heat across the Southwest region.  Transient patterns usually also yield for potential wetness and we note the GFS Ensembles trending in that direction to wrap up the month.

gfs-ens_apcpna_us_10In the shorter term, there will also be localized heavy downpours, but it’s a continued case of “haves and have nots.”  There won’t be any particular rhyme or reason to the specific placement of heavy, gully-washer type showers and storms mid week.

Finally, to close, perhaps the MJO shows the pattern best over the next couple weeks.  Best word to describe the MJO’s idea?  Transient.  🙂

Turning Less Humid…

Screen Shot 2016-06-12 at 10.33.00 AMHighlights:

  • Storm threat over the southern half of the state
  • Turning less humid
  • Scattered mid week storms
  • Cooler to close the week

Another Hot One…A weak frontal boundary will slip through central IN this afternoon and evening and serve as a “trigger” for isolated to widely scattered thunderstorms for central and southern parts of the state.  We’ll also turn less humid this evening into Monday.

Warmth and humidity surge again Tuesday and there will be times of scattered showers and thunderstorms through Thursday.  Uniform rains aren’t expected, but there will be some localized heavy downpours.  Remember the saying of “haves and have nots.”

A cooler northeasterly air flow will arrive to “freshen things up” a bit as we close the week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.25″-0.75″

Friday Evening Video Update…

A hot and humid weekend is in store, but we’re eyeing increasingly wet and unsettled times by the middle of next week…

Turning Hot; Challenging NW Flow Pattern Aloft…

Screen Shot 2016-06-09 at 7.40.04 AMHighlights:

  • Storm chances for some by this afternoon/ evening
  • Turning hot and humid
  • Better chances of widespread rain by the middle of next week

Plan To Sweat…The period opens with a challenging northwest flow aloft.  Already this morning we note a complex of showers and thunderstorms across MN and IA.  This storm complex will continue to drop to the southeast and will likely impact portions of the state later this afternoon and evening- especially north and northeast areas.  An additional storm complex is possible Friday.

The big story to close the week and head into the weekend will be the push of hot, humid air.  Many will be close to 90 degrees tomorrow and widespread lower 90s are a lock Saturday.  Plan for frequent breaks if your plans take you outside for any length of time.

As we look deeper into next week we note an increasingly wet and stormy signal on the models and will trend our forecast in that direction for the middle and latter portions of the week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.50″-1.00″

Refreshing Feel…

Screen Shot 2016-06-07 at 10.30.54 AMHighlights:

  • Dry and refreshing
  • Heat and humidity build
  • Timing rain and storm chances

Open The Windows…A northwest flow is ushering in a refreshing feel across the region today.  Find a way to eat lunch outdoors and open up the windows to let the fresh air in!  Dry conditions will prevail into mid week.  The coolest night will come tonight/ Wednesday morning with lows in the lower 50s (wouldn’t be surprised by upper 40s away from the city in spots).  Gradually moderating temperatures will come for the latter portions of the week, and showers and thunderstorms could pop as humidity surges Friday.

The weekend looks downright hot- especially Saturday.  Timing of southwest-moving thunderstorm complexes will be an issue over the weekend, but for now we think Saturday is dry and want to mention the threat of storms Sunday.  Stay tuned as we fine tune things.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 0.50″-0.75″
