Severe Weather Next Week?

It's that time of year again; severe weather season is about to crank up here in the South. After temperatures in the teens (and even a few single digit reports) in North Alabama this might seem hard to believe. But it was one year ago this week that we endured the Super Tuesday tornado outbreak. Storm spotter classes are being conducted in various locations in North Alabama by the Huntsville NWS office and surrounding offices. Next week is severe weather preparedness week.

While all of this preparedness activity is occurring, parts of the Plains and the South may be under a risk for severe weather next week. A few waves of low pressure are likely to move across the Southern Plains. The second of these waves will carry an incresed chance of severe weather, perhaps around midweek. Stay tuned.

From the SPC:

...DAY6-8/TUESDAY THROUGH FRIDAY... THE SYSTEM CROSSING THE PLAINS THROUGH DAY5 MAY SET THE STAGE FOR A MORE WIDESPREAD EPISODE OF SEVERE WEATHER OVER THE CNTRL U.S./MS VALLEY REGIONS ON DAY7/WEDNESDAY. THIS COULD OCCUR AS A HIGHLY AMPLIFIED AND FAST-MOVING SHORT WAVE TROUGH MOVES EAST FROM THE PLAINS AND SUPPORTS THE DEVELOPMENT OF A STRONG SURFACE CYCLONE AND COLD FRONT PER LATEST GFS. THIS NEXT SYSTEM WILL HAVE THE POTENTIAL TO TAP INTO HIGHER MOISTURE/GREATER INSTABILITY BROUGHT ABOUT BY THE ENHANCED RETURN FLOW LEFT IN THE WAKE OF MONDAY/S DISTURBANCE.
