More Storms Sunday

**No afternoon Weather Xtreme video today… scroll down for the morning video**

Be sure and scroll down for lots of damage pictures and storm survey info from the NWS in Birmingham. While the clean-up continues from yesterday’s storms, now our attention turns to the event Sunday.

OUR WEEKEND: First off, tomorrow promises to be a beautiful day, with a sunny sky and a high in the mid 70s. Then, Sunday, yet another dynamic storm system will blow in here Sunday. Not as impressive as the one we dealt with yesterday, but still it will bring some risk of strong to severe storms. Here are some severe weather parameters from the NAM for Sunday afternoon:

Surface based CAPE 739 j/kg
Lifted index -5.0
0 to 3 km helicity 453.6
SWEAT index 399.3
850 mb winds 31 knots
500 mb winds 49 knots

Wind fields are marginal, but there should be sufficient instability and shear for the threat of severe thunderstorms Sunday afternoon and Sunday night. SPC has most of the state in a severe weather risk, and it looks scattered storms will fire up Sunday afternoon; those are the ones will have to watch for signs of rotation. Then, a squall line should move through the state during the evening hours. The main window for severe weather seems to be from about 1:00 p.m. until 8:00 p.m. We, of course, will fine tune that risk over the weekend.

FREEZE THREAT NEXT WEEK: The 12Z GFS is printing 28 for Birmingham on Tuesday morning, and 31 on Wednesday morning. These values look good considering the depth of the eastern U.S. upper trough that forms, and of course we all know that valley locations will be colder. Growers will need to prepare for a freeze on both mornings, with Tuesday morning being the coldest, in all probability.
