Severe Weather Potential For the 22nd

The system that produced the severe weather in the central and southern plains and across the southeast the past several days has one more day of severe weather that it will be producing ..HOWEVER...today will not be an outbreak type of severe weather day as that system has been weakening and losing strength...
Here is the reports for the 21st and you can see not one tornado had occurred which is a vast improvement over the previous days. With the system weakening we are not really expecting today to be a day for tornado's either. 
The main threats should be Hail and Wind across the severe zone. Lets look at the severe parameters that will be in place...

First off the temperatures will be in the 70s to 80s depending on where you are..
Dew points also once again will be in the 60s and 70s across the region..

Wind shear depending on where you are is going to be marginal at about 30-40 knots and if you are in PA  it will be even less then that...highest shear is in the northeast region.
CAPE will be marginal in some areas from 500-1000 and then the highest CAPE is across eastern PA into NJ and parts of the Northeast. Unfortunately, the shear is not the greatest so despite the CAPE this could hinder severe development in that area. Super cells are possible with the stronger storms with the EHI around 1...
There is ample lift in the atmosphere with the LI index down to about negative 7..
The culprit once again will be the trough and cold front that has been slowly advancing towards the east with the severe threat slowly advancing towards the east. The difference is parameters today are a lot lower and the system has weakened compared to what it was. 
The trigger across the Northeast part of the region will be the warm front that is to be draped across northern new england.

So with all the above in mind here is the outlook for today with once again winds , hail and heavy rains being the main threats.
We here have to say we are glad with the damage that has already taken place especially in places like Oklahoma. Please remember to keep them in your prayers cause even though the #s may not be as high as what they were originally thought there are still alot of families effected and without a place to live and some that lost family members!
