Indystorm

The line in central IL seems to be breaking up into somewhat more quasi discrete cells as it moves se into an area of 450 m2/s2 helicity. Needs to be watched even though bulk shear is higher to the north.

Helicity has increased significantly over eastern IA from what it was earlier this evening, probably accounting for the sig tor values up to 3 in the area. We'll see if storms weaken as they head east.

Bulk shear is increasing across most of IA with ML CAPE around 2000 ahead of that tor producing cell as it moves e/se. Helicity, however, is higher to the nw of the cell.

Confirmed tor on the ground nw of Mason City at present time of 3:45 CDT.

Have always appreciated your insights, knowledge, and cautions over the years and extend my best congratulations.

Baseball size hail tor warned cell west of Poplar Bluff Mo just before 5 p.m. CDT.

And here at Fortville I managed to miss the svr warned cell issued for Hancock County earlier this afternoon. Will see what any stray cells coming in from IL may hold yet today.

This. We need some 990mb systems to augment that low level jet which we have had a dearth of this spring here in the Midwest.

Gee, all the MCS's make me think that this is mid July. Whatever happened to spring storm season?

Yes, it is usually the NAM that tends to go overboard on CAPE values on occasion. Your posted map surprises me.

Well, what do you know> ERTAF puts up a map for week 2 outlook graphic right in the heart of tornado alley from TX north to Kansas. First time they've felt confident enough to post a map in awhile.

Had not read about the volcano. I wondered what might have caused the intense Greenland block. Only read about stratospheric warming.

Well, a year without a spring might be better than 1816 and Mt. Tambora volcano causing the year without a summer. But who knows what might yet happen in May and June.

The 4/10 EURO is somewhat surprisingly looking better with svr prospects from eastern Nebraska southward for Friday. Will this portend better chances for Sat. into IL and IN? Stay tuned. Some Indpls TV mets are now mentioning the possibility of svr storms for Saturday and saying the situation must be watched.

Sunday's 12Z GFS much more sensible with the strength of the low pressure for this coming Friday. Not the extremes we have been seeing and puts more of IL and IN in realistic play.

Well, for the first time in seemingly ages my IND NWS 8-10 day forecast this morning is calling for ABOVE normal temps and precip. Pattern change?

The daffodils are blooming in my front lawn. Such is the difference in climo and geography from Michigan to Indianapolis. Plus I also have a new pond in part of the yard from all the recent rain and snow melt.

And I admit I have concern for the Gadsden area later this evening as that monster cell to their nw moves se along the warm front boundary.

As if we need training west to east tornadic supercells with good inflow from the south.
