Hazardous Weather Outlook, Jan 22, 2012

Please refer to the earlier post from today for more information from the Storm Prediction Center.  This post is an update, to include the most current Hazardous Weather Outlook.

A low-pressure system currently over North Texas and Oklahoma will move northeast this evening, bringing Gulf moisture north to meet the cold front.  Western portions of Mississippi will likely see storm development around 7pm through 11pm.  Areas along and east of the Interstate 55 corridor will see storms overnight between 9pm and 4am Monday morning.  Development of a broken line of strong thunderstorms is expected for Western Mississippi, including the possibility of the formation of discreet supercell storms.  Damaging winds up to 80 MPH and golfball size hail are also possible with these storms. All of North Mississippi is in an enhanced-risk area for damaging tornadoes of EF-2 strength and greater.

This is a significant risk, and highly unusual for this time of year.  If you have a NOAA Weather Radio, please take time now to make sure it is working properly.  Do not wait for visual confirmation of severe weather or tornadoes before taking action during warnings.  Know your weather safety plans, and be prepared to act on them quickly.
