HillsdaleMIWeather Posted April 26, 2017 Share Posted April 26, 2017 Severe Thunderstorm Watch out of literally nowhere for Northern Indiana and Northwest Ohio, those area's aren't even in the marginal risk! EDIT: If you want to get really technical, part of the watch is in in the Day 2 Outlook, and the watch goes to midnight. Link to comment Share on other sites More sharing options...

geddyweather Posted April 26, 2017 Share Posted April 26, 2017 New SPC outlook adjusts accordingly to the Svr Thunderstorm Watch just issued. Slight risk pushed into central/Ern Indiana, Marginal into NW Ohio and north to the MI State Line. Link to comment Share on other sites More sharing options...

Indystorm Posted April 26, 2017 Share Posted April 26, 2017 That cluster of storms sw of Indpls has been very intense ever since crossing the Mississippi earlier today. 80 mph wind gust in svr warning aside from the tornadic cell. Link to comment Share on other sites More sharing options...

Curious to see how much rain falls here tonight. The NAM/GFS are putting that 2" band through here but the HRRR has consistently been less bullish or farther east. Don't have a lot of confidence in 2" amounts here at this point, but if something like it does occur, then it's step 1 of priming the pump.

Indystorm Posted April 26, 2017 Share Posted April 26, 2017 Concerned that the tornadic cell is much more of a deviant right mover than I would have expected from that cluster of storms. I can see dark clouds to my nw from the svr warned storm expected to impact Lebanon and Thorntown. Link to comment Share on other sites More sharing options...

nwohweather Posted April 26, 2017 Share Posted April 26, 2017 Massive hail cores on those two severe cells north of Indy right now. LI's aren't that terrific but okay CAPE and terrific shear should give us a nice little event this evening Link to comment Share on other sites More sharing options...

HillsdaleMIWeather Posted April 27, 2017 Share Posted April 27, 2017 SUMMARY...Severe hail and wind may persist another 1-2 hours across the watch area. However, a gradual weakening trend is expected as inhibition increases with loss of daytime. DISCUSSION...Widely scattered strong to severe thunderstorms will continue to track northeast from central IN toward northeast IN/northwest OH. These storms are in a zone of modest MUCAPE in the 500-1000 J/kg range with 50+ kt effective shear. This will maintain activity for several hours, but as inhibition increases with loss of heating, and as storms move into region of poorer low-level moisture, gradual weakening is expected. In fact, latest 7km CAPPI trends indicate this weakening is already underway. Expect the severe threat to persist another 1-2 hours before storms weaken. The main threat will continue to be hail and strong winds. A downstream watch is not expected. Link to comment Share on other sites More sharing options...

Yeah you can really tell the lapse rates are good when you get prolific lightning producers like this. Reminds me of storms in the 90s those always seemed to be great lightning producers.

Powerball Posted April 27, 2017 Share Posted April 27, 2017 Definitely a bust in terms of an overachiever today. The SPC shows that nearly 30 storm reports (all in Indiana) ended up being outside of the Marginal Risk area (let alone the Slight Risk area)...

Yep, 69 MPH wind gust with 45 MPH sustained winds. Beyond that, the biggest take away for me looking at the ASOS are the shifting winds (from S to SE to SW to NE then SE again). Had instability and moisture been a bit higher, things could have been notably worse today (from a tornado standpoint). Link to comment Share on other sites More sharing options...

IWXwx Posted April 27, 2017 Share Posted April 27, 2017 I've been pretty busy lately, but wanted to post that the completely unexpected severe storm that rolled through here last night was one our better in several months. Almost constant lightning and a prolific pea sized hail producer. We also had a swatch of wind damage, producing 8 PNS reports in our county alone. It was fun to spot/chase.

Hoosier Posted April 27, 2017 Share Posted April 27, 2017 Only about a half inch of rain around here, less than most guidance was suggesting. Link to comment Share on other sites More sharing options...
