As i mentioned a couple of days ago i figured the tables would somewhat turn as it seems now alot of the storm action over the next couple of days will spread out some and may give some much needed relief to the se. Not all will get in on it but the chances for storms will be alot better then they have been.

Bump ...

Extremely Severe Weather occurring over NE and poised to head into IA ... latest radar imagery and velocity vectors indicate no less than 6 supercells, possible more...each capable of producing very large hail (one of the cells has a VIL of >75!), very damaging straight line winds (some of the cells have as much as 90 kts of gate to gate shear), and potentially violent tornadoes ...

Furthermore, with the warm front draped across the region, the potential also exist for training cells (hence a flooding potential) and outflow boundaries from storms further south earlier have also enhanced the current activity in NE ... watch out Southern NE as a new line has begun to erupt as two outflow boundaries are colliding (one from the south, and one from the supercell family to the north) ...

Stay safe ...

Like many cities in the central part of the US in 1993, KC was NOT dry for the first part of 1993. We were hit with numerous rounds of thunderstorm from May tothe end of July. Flooding was a problem here. But the levy systems on the Missouri and Kansas Rivers held in the cities of both KCK and KCMO.

The problem is the strong deep layer ridge which has been sitting along the SE coast for weeks now. all the upper level support for widespread/organized convection has been directed up and overtop of it as we have seen with todays SVR WX over the central plains, corn belt on into the northeast and new england.

Convection, especially across FL and SE GA has been reliant on sea breeze boundaries as a focus for low level converegence and convective initiation over much of the past few weeks absent any organized large scale forcing.

UNTIL we can beat down the deep layer ridge off the east coast, DON'T expect any big changes in the pattern.

Interior central FL will cook again tomorrow as combination of low level thicknesses between 1420-1425 meters and 850mb temps up to around 16-17C with near full sun the underneath the thermal ridge, should yield surface temps of near or just slightly above 90F./

Further North into GA, interior SC and NC, 1425-1430 meters and 850mb temps of up to 18C per 0z MESOETA should contribute to surface temps in the lower 90s, where daytime heating is the strongest.

SOME convection may once again fire late in the afternoon E of the mountains.
