Drying Out; Late Season Push Of Summer Air…

screen-shot-2016-09-17-at-10-22-44-amHighlights:

  • Showers become more scattered this afternoon
  • Nice Sunday on deck
  • Late season push of summer heat before cooler times

Drying Out Sunday…It was a wet and stormy night across central IN, including locally hefty rainfall totals (some neighborhoods picked up more than 2″).  We’ve been dealing with widespread soaking rain across central IN through the morning, but as we progress into the afternoon, most concentrated rain will remain east of the city and on into Ohio.  Scattered showers will remain possible until the cold front presses through the region tonight.

High pressure will build overhead Sunday and supply increasing sunshine and a pleasant second half of the weekend.  Lower humidity will promote overnight lows into the upper 50s to open the week.

A secondary (weak) front may yield an isolated to widely scattered shower Tuesday, but the bigger story will be late season heat building to close the week.  Highs will approach the 90 degree mark by Friday as a big ole ridge expands across the region.

Longer term, a significant cold front looms just beyond the current forecast period that will offer up thunderstorms and a big blast of fall-like air to close the month…

Upcoming 7-Day Precipitation Forecast:

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

Turning Unsettled This Afternoon…

The initial push of moisture will ride into central IN this afternoon (likely between 2p-3p time frame).  Embedded thunder will be a good bet, but the storms pushing in should be in a weakened state compared to what our neighbors to our west will experience a few hours earlier.

1Periods of scattered showers and thunderstorms will continue Saturday.  The good news?  After the initial round of showers this afternoon, most high school football games could very well be dry tonight.

3It won’t rain the entire time Saturday, but scattered storms are a good bet through the day.  Some locally heavy rainfall is likely, but rain amounts won’t be uniform.  On average 0.75″-1″ is a good bet.

kind_2016091521_tqpfSunday will be the pick of the weekend as high pressure builds in and supplies a drier air mass.  Flipping the page to next week, the big story will be a late season push of summer heat followed by a significant cold front next weekend.  Behind this front, a true push of bonafide autumn air will push in.  Sweaters and jackets will likely be needed as we put a wrap on September…

Drier, Cooler Air On Our Doorstep…

screen-shot-2016-09-10-at-9-20-41-amHighlights:

  • Greatest storm coverage and intensity this morning
  • Turning much drier and cooler
  • Reinforcing mid week cool air

Turning Much Drier This Evening…It’s been a wet and stormy time of things as of late.  Locally heavy rain will continue to accompany stronger storms this morning, but we note greatest storm coverage should begin to shift ENE as the morning progresses into afternoon.  Renewed showers will likely develop this afternoon as the cold front moves through the state.  We’ll then enjoy a marked NW wind shift this evening and that will help push much drier and cooler air in to help create a true fall feel tonight.  The second half of the weekend look beautiful- sunny and crisp!

Much needed dry time will be with us for the balance of the upcoming work week.  We note a reinforcing push of cool air mid week that could spark a shower, but rainfall amounts don’t look impressive (the air will be much drier than the “soupy” feel we’ve been dealing with for the past week).  A more significant rain-maker should arrive next weekend…

Upcoming 7-Day Precipitation Forecast:

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

Periods Of Heavy Rain Then Much Cooler…

A “wavy” frontal boundary will be located over our region through the next 36-48 hours before getting a “shove” south from a cold front Saturday. 


The combination of the stationary front along with a tropical-rich air mass in place will be enough in and of itself to produce periods of heavy rain today into Saturday morning. Add in a couple of disturbances moving along the boundary and the heavy rain prospects grow even higher. A strong to severe storm also can’t be ruled out-primarily this afternoon and again Friday afternoon. 

Already this morning (6:30a) we note widespread showers and embedded thunder impacting IL and northern IN. 


As mentioned, the air mass is plenty “juicy” to fuel locally heavy rain through the period. Precipitable water values (PWATs) will surge north of 2″ for all of central IN later today. 


While it won’t rain the entire time, periods of heavy rain will remain in our forecast today through Saturday morning. Widespread 1″-2″ totals will be common, with locally heavier totals. 


High pressure will build overhead Sunday and lead to quite the change. A much cooler and drier air mass will return along with brighter skies to wrap up the weekend. 


Lows in the middle 50s will be common for the city, itself, Sunday through Tuesday mornings. Upper 40s to lower 50s are a good bet away from the metro.
