Much Cooler Air Coming…

Screen Shot 2015-05-18 at 7.35.41 AMHighlights:

  • Spotty shower or storm today
  • Much cooler Tuesday-Thursday
  • Light rain chances Wednesday
  • Keeping a close eye on Race Day/ Memorial Day wknd

A cold front still sits to our west and as the front passes through the region later this evening, an isolated or widely scattered thunderstorm will be possible, with best chances across the southeast portion of the state.  A much cooler air mass will then filter into the region for mid and late week.  A weakening disturbance may hold together just long enough to deliver some light rain Wednesday.  With added cloudiness and moisture, temperatures may not even make it out of the 50s for highs Wednesday.  Our next chance of rain will arrive Sunday, but this doesn’t appear to be any sort of significant event at this juncture- just a scattered afternoon shower or storm chance at this point.  We’ll keep a close eye on things.

1A cold front will move through the region this evening and this could spark a thunderstorm, particularly across southeastern IN.

2Our next chance of rain arrives Wednesday.  Factor in increased cloudiness and the unseasonably cool air mass in place and you have the makings for a rather cool, raw day.

One More Pleasant Day Before Warmth And Humidity Increases…

Screen Shot 2015-05-13 at 9.33.32 PMHighlights:

  • Another chilly start
  • Warmth and humidity on the uptick heading into the weekend
  • More dry hours than wet this weekend
  • Much cooler next week

We’ll enjoy one more beautiful day Thursday, though we’ll note an increase in afternoon cloudiness.  While a shower will be possible Thursday evening (courtesy of a warm front passing through the region), it won’t amount to much as dry air will “eat away” at what will look like a rather impressive surge of moisture to our west Thursday morning.  Once the warm front blows through tomorrow night, a much more humid and unseasonably warm air mass will engulf the region to wrap up the work week and head into the weekend.

A widely scattered storm will be possible, but there will be many more dry hours than wet.  Better coverage of showers and thunderstorms arrives Sunday night/ Monday as a cold front presses through the region.  Total rainfall potential between this weekend and Monday looks to fall in the half inch to one inch range for most.  A much cooler and drier air mass returns next week (even cooler than this current air mass).

1A light shower will be possible Thursday evening as a warm front lifts through the region.

2Warmth and humidity will be on the uptick Friday and continue through the weekend.  Prepare to sweat as dew points approach 70 degrees this weekend.

3Most widespread showers and thunderstorms will arrive Sunday evening into Monday, courtesy of a cold front passing through the region.

4A MUCH cooler air mass will settle into the Mid West region next week.  In fact, next week’s chill looks more impressive than our current cool air mass- both from a duration perspective and absolute temperature.

A Much Cooler, Drier Trend…

Screen Shot 2015-05-11 at 8.51.04 PMHighlights:

  • Much cooler and drier through Thursday
  • Moisture increases this weekend
  • Stormy early next week

A cold front swept through the state this evening and a much drier and cooler brand of air is filtering into IN as we type this.  That cooler and drier regime will carry us into late week before moisture slowly begins to return.  High pressure will shift east and allow a moist return flow Friday into the weekend.  Add in a couple of disturbances and the associated forcing, combined with the increasing warmth and humidity, and the stage is set for periods of showers and thunderstorms over the weekend.  It certainly won’t rain the entire time, but plan on localized heavy downpours.

hrrr_t2m_indy_14A MUCH cooler air mass will greet Hoosiers out the door Tuesday morning.  Even cooler air will be with us Wednesday and Thursday mornings.

gfs_ptype_slp_conus2_9High pressure will supply plentiful sunshine and cooler than normal air through mid week.

gfs_ptype_slp_conus2_16A southwesterly return flow will lead to increasing chances for showers and thunderstorms across not only our local area, but across a widespread portion of the Plains and Ohio Valley.  Furthermore, a significant severe weather outbreak appears to be a good bet across the Plains.

cmc_total_precip_indy_33After a dry mid week stretch, active times return over the weekend into early next week.  Localized torrential downpours are likely.  Most of the 1″ to 2″ of rain forecast shown above (courtesy of the GEM model off the Weatherbell.com suite) is expected to fall early next week.
