Warm-up, rain on the way for central Indiana

Updated:
INDIANAPOLIS -

Despite a full dose of sunshine temperatures are running a healthy 15 to 20 degrees colder than normal, following our coldest morning in nearly two weeks.  Conditions remain tranquil, but cool, this evening with clear conditions until around midnight.

RPM

Rain arrives for most by 7-8am and paves the way for a soggy start to Thursday.  It wouldn't shock me to some sleet mixing with rain at the onset, but the atmosphere should sufficiently warm quickly enough for mostly liquid precipitation tomorrow.

Due to limited/non-existent instability I don't anticipate severe storms locally, but we'll definitely hear the occasional rumble of thunder and some heavy downpours.  Within the deeper moisture fields and higher instability along the Mississippi River severe storms are possible Thursday and tomorrow night.

RISKMAP

Highs Thursday likely occur after 5-6pm and will near 50 degrees despite the cloud cover.  Tens of thousands of basketball fans will descend on Indianapolis for the Midwest Regional Friday and Sunday.  Though Friday begins cloudy and damp, the passage of a weak cold front will allow drier to return Friday afternoon.

The finish of the day should be fairly nice with comfortable highs in the middle 50s.  But the break from precipitation won't be long, as a new system we touched on in prior blogs quickly emerges by dawn Saturday.  Rain will mix with snow on the northwest/colder side of an area of low pressure riding across the Ohio River Valley.  We're not expecting accumulation at this point, but can't completely rule out a localized slushy covering by late Saturday morning.  With or without accumulation, Saturday will be damp and raw with cool highs in the lower to middle 40s.

Sunday will easily be the better day of the weekend, as a brighter sky returns and highs near 60.  The pattern remains active next week with several storm systems set to impact the region between Monday and next weekend.  Have a great evening and thanks for reading the blog – Sean Ash
