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.

Lots Of Dry Time This Weekend, But Scattered Storms Will Be Around…

Screen Shot 2015-05-09 at 10.38.36 AMHighlights:

  • More dry time than not this weekend
  • Strong storm potential Monday
  • Cooler and much drier air moves in Monday night

The region remains in a very warm and moist air mass this weekend and this could help promote a scattered shower or thunderstorm really at any point over the next couple of days.  That said, best concentration of rain and storms will come during the afternoon and evening hours.  All-in-all, the weekend will feature many more dry hours than not.  A final push of showers and thunderstorms will blow through Monday and some of these could reach strong to severe levels.  We’ll keep a close eye out.  A much cooler and drier air mass arrives Monday night and that will carry us through Thursday.

hrrr_ref_indy_10Most of today will be dry, but forecast radar (courtesy of Weatherbell.com) suggests showers and thunderstorms build into central IN this afternoon and evening.  Plan on taking rain gear with you if you have outdoor plans and have a means of getting inside should a storm be nearby.

day3otlk_0730The SPC has highlighted a large portion of the Ohio Valley for the threat of severe weather Monday.  Large hail and damaging winds appear to be of greatest concern at this time.  While this doesn’t look like a significant widespread severe weather outbreak for our immediate region, let’s remember it only takes one severe storm impacting a community to be significant in that particular neighborhood.

Light Rain And Snow Showers Around This Afternoon/ Evening…

Scattered light rain and snow showers will dot the central Indiana landscape this afternoon and evening as colder air moves into the region.

hrrr_ref_indy_14

Thursday and Friday will be colder than what we’ve been used to the past few days, but nothing out of the ordinary and actually more seasonal.

We’re still eyeing a late weekend clipper system, but the precise track will determine who sees “several” inches of snow, versus little to nothing. Feast or famine, we’ll call it!  Overnight computer model guidance would place the heavier snow totals across northern portions of the state, but we still have a ways to go before anything is set in stone.

Back later this evening with a complete 7-day update!
