Thunder Road Posted May 11, 2014 Share Posted May 11, 2014 What?! You chose finals over chasing? Seriously though, probably a good call. Regretting it a little bit now since we likely could have made it to Ottumwa by now. Oh well, you win some, you lose some. Link to comment Share on other sites More sharing options...

Powerball Posted May 11, 2014 Share Posted May 11, 2014 It'll be interesting to see how that MCV in Iowa evolves with the convection redeveloping across IL/WI. I wouldn't be surprised if the storms get as far east as here late this evening, based on radar trends. Link to comment Share on other sites More sharing options...

Powerball Posted May 11, 2014 Share Posted May 11, 2014 Yes and if it does come through late this evening that means less or no crapvection all night to completely beat up the atmosphere. Meh, as long as we're getting decent heating by 10am-ish and another MCV tracks through late in the day, we should be fine. The models still show a decent surge of mid-level dry air for the afternoon hours tomorrow, which remains a plus. Link to comment Share on other sites More sharing options...

Hoosier Posted May 11, 2014 Share Posted May 11, 2014 I see Waukegan at 68/53, not exactly Tropical, likely will die out before it gets to shore. Perhaps, but that cooler/drier airmass is not extending very far inland so there may not be enough time. Man, monster cell out in Nebraska. Makes our stuff look like child's play.

Geos Posted May 11, 2014 Share Posted May 11, 2014 I see Waukegan at 68/53, not exactly Tropical, likely will die out before it gets to shore. Lake breeze isn't really doing much here (wind isn't ripping in at all). The shallow marine layer won't probably do anything to the storms heading in until they get over the lake. Still above 70° here. Warning just extended to the lakefront.
