Slow Going This Morning…

Freezing drizzle and areas of light snow will continue into the early afternoon hours before we finally begin to dry things out.

Temperatures are in the upper 20s for most central Indiana communities this morning and it’s not until we get into the early to mid afternoon hours when we anticipate temperatures to climb to around freezing.  As a result, slick conditions (especially side streets and back roads) can be expected into the afternoon and evening hours.

Overnight lows tonight will fall into the lower to middle 20s so re-freezing and slick spots on area roadways can be expected into Thursday morning.

Thankfully, a southwesterly air flow and new warming trend will develop through the day Thursday, along with a return of sunshine!

Much more later today on the developing new cold pattern…

Wet To White (At Times) Through Early Week…

A quick note before we dive into the upcoming forecast pattern.  Instead of issuing 7-day posts within the blog format, the most updated IndyWx.com 7-day forecast will now be featured at the top left of the site.  We’re continuously trying to provide you the information and content you need in a quick and concise manner- eliminating having to “scroll and search” (unless you’re bored, of course ;-))!

Areas of fog and drizzle will continue this evening before a stronger southwesterly air flow pushes the low clouds and fog north during the overnight.  As a cold front draws closer, steadier rains and perhaps even a clap of thunder (especially down state) will arrive Monday morning.  Temperatures will remain nearly steady or even rise overnight into the lower 50s.

The frontal passage, itself, will take place Monday evening and may feature a couple of gusty showers, especially across western and central portions of the state.

Temperatures will grow colder Monday night into Tuesday morning and precipitation will end as snow showers Tuesday.

High pressure will build in through midweek and provide dry conditions with increasing sunshine.  The midweek stretch will begin seasonable before warming ahead of our next storm system.

That next storm system will deliver rain as early as Friday evening into Saturday.  We’ll note an increasingly gusty southwesterly breeze as we wrap up the work week, along with increasing cloudiness.

Milder, But Active…

Highlights:

  • Gloomy close to the weekend
  • Rain-to-snow early week
  • Significant storm next weekend

Drizzle And Fog Develops…Our Saturday opened with plentiful sunshine and milder conditions.  Unfortunately, the low cloud deck invaded through the afternoon hours and will take up residence through Sunday.  Fog and drizzle will develop tonight and continue through most of Sunday.

Steadier rains will arrive on the scene late Sunday night into Monday morning ahead of an approaching cold front.  That cold front will sweep through the state Monday afternoon with additional showers and a dramatic wind shift.  Colder air will then press into the region and as wrap around moisture swings through the state, snow showers will develop Tuesday.

As mentioned in previous posts, we’re in a transient and very active regime.  Just as soon as the colder air arrives for midweek, we’ll shift our air flow around to the southwest and usher in milder times to close the week.  A significant storm system is brewing next weekend.  We’ll forecast increasing cloudiness Saturday with rain arriving by afternoon.  We’ll have to keep tabs on next Sunday for the possibility of wintry conditions returning…

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: Dusting
  • Rainfall: 0.50″ to 1.00″

Friday Morning Notebook: Warmer Times This Weekend…

Happy Friday, friends.  We’re still cold this morning, but a look at the change in temperatures compared to 24 hours ago shows the milder trend that will be with us through the upcoming weekend.  Highs today will reach the upper 40s and 55-60 Saturday.

Winds will turn strong and gusty out of the southwest this afternoon, noted by the tightly packed isobars (lines of equal pressure) along with considerable mid and high level clouds.

Clouds will lower and thicken Saturday and we may also have to deal with periods of fog, as well.  Showers and drizzle will lift into town as the day progresses, especially by afternoon and evening.

We don’t expect heavy rain this weekend.  In fact, model data continues to really back off on expected totals.  The general consensus is between 0.15″ and 0.25″ across central Indiana.

After a mild Saturday, cooler (but not cold) air will ooze into the Ohio Valley Sunday.

Resurgent cold air will blow into town during the middle and latter portions of the upcoming work week.  Highs will return to the 30s with overnight lows in the lower 20s.  We’ll likely add scattered snow showers into the mix as well.

Icy Concerns Grow Again Tonight…

After a night of freezing rain, many roadways throughout central IN remain glazed over and hazardous as of this update.  If you absolutely don’t have to travel today, please don’t.  Allow road crews to do their job.  Additionally, we have growing concerns of a new round of freezing rain to sleet and eventually snow tonight.  Lingering moisture on roadways will result in “flash freeze” conditions and treacherous travel tonight into Sunday.

First, a tip of the hat to short-term modeling, including the NAM, for suggesting we’d have a very difficult time eroding the shallow arctic air at the surface across most of central IN today.  While we never bought into the mid/ upper 50s idea the GFS and Euro were once suggesting, we did initially think 40s were in store today.  Forget about it.  Mid to potentially upper 30s are the best we can do today and temperatures will crash this evening as not one, but two, arctic fronts push through central IN.  Even if we didn’t have additional precipitation inbound tonight, “flash freeze” conditions would develop from lingering moisture and lead to renewed problems on area roadways.  Throw in another wave of low pressure riding along the pressing arctic front and a whole slew of problems will develop yet again from a freezing and frozen precipitation perspective.

Note the incredible temperature gradient from downstate to central and northern Indiana early this afternoon.

hrrr_t2m_indy_6The heavy, dense, arctic air will win out as evening turns into nighttime.  Indianapolis is back to the freezing mark around 6p and into the 20s by 9p.

hrrr_t2m_indy_10

hrrr_t2m_indy_13Temperatures will continue to fall through the day Sunday and by Monday morning central Indiana will be in the single digits, with below zero readings across northern parts of the state.

hires_t2m_indy_49Wind chill values of 10 to 20 degrees below zero will be common by Sunday night into Monday morning across central Indiana.

gfs_windchill_indy_8Areas of drizzle and freezing drizzle will continue across the region into the early afternoon, but begin to expand in coverage and intensity once again by evening.  Note the area of freezing rain expand across central IN, including Indianapolis, between 4p and 7p.

4p

6p

7pFreezing rain will eventually begin to mix with sleet and eventually transition to light snow during the overnight from northwest to southeast.  A coating of snow to less than 1″ is a good bet on the new icy glaze that develops tonight.

When you factor in the current hazardous conditions in place along with the fresh push of arctic air and precipitation tonight, it’s a good idea to hunker down inside and remain off area roadways.  We have big concerns of new travel problems developing by evening across central Indiana.  By this time tomorrow, our attention will turn to the bitterly cold air and dangerous wind chill values developing.

More later, including prospects of snow around Christmas.  As always, you can follow our updates on social media by following us on Twitter (@indywx) and Facebook.  Stay safe!
