PSUBlizzicane2007 Posted April 28, 2014 Share Posted April 28, 2014 That outflow boundary over middle Tennessee reminds me a lot of yesterday with the boundary that set up over central Arkansas. Slightly different, but I would certainly be watching that later this afternoon into tonight after the convection clears out and some sun and fuel can get into the area Link to comment Share on other sites More sharing options...

Hoosier Posted April 28, 2014 Share Posted April 28, 2014 There's been a decent amount of sun in parts of the northern target area of IA/IL. Wouldn't be surprised to see a MCD for that region soon. Link to comment Share on other sites More sharing options...
Calderon Posted April 28, 2014 Share Posted April 28, 2014 Of all days: MEG -- KNQA 88D IS DEGRADED AT THIS TIME. DUAL POL PRODUCTS ARE UNRELIABLE. STANDARD RELECTIVITY PRODUCTS ARE LIKELY HIGHER THAN THEY SHOULD BE. THIS WILL IMPACT PRECIPITATION PRODUCTS AND OTHER PRODUCTS AS WELL. MAINTENANCE WILL BE PERFORMED AT THE LATEST ON WEDNESDAY DUE TO ONGOING SEVERE WEATHER. Link to comment Share on other sites More sharing options...

Hoosier Posted April 28, 2014 Share Posted April 28, 2014 I'm actually paying more attention to that area of the SPC mesoanalysis (also in part because I know parameters will be great in MS). Pretty sharp boundary but expected storm motions suggest that storms may not have long residence time near it. Link to comment Share on other sites More sharing options...

Thundersnow12 Posted April 28, 2014 Share Posted April 28, 2014 lol. Large warm sector with a several hour window for action. lol Eh. Think storm relative hodograph. Shear won't be great until they are actually crossing the warm front. Mostly unidirectional until they hit the front. They wont do much until then IMO.
