The SPC continues to monitor the severe weather threat across Alabama this morning.
A line of strong storms is moving east through Central Alabama, currently these storms are not severe, but are producing gusty winds and very heavy rainfall. There remains a threat for severe weather, especially along and east of this line of thunderstorms. The line of storms is approaching the edge of the current tornado watch, and a new watch could possibly be issued for portions of East Alabama.
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 587…588…CONTINUES.
SUMMARY…THE SVR THREAT CONTINUES FOR REMAINING VALID PORTIONS OF
WW 587… AND A NEW TORNADO WATCH IS BEING CONSIDERED TO THE EAST
AND SOUTH THAT WOULD INCLUDE FAR SRN PORTIONS OF WW 588.
DISCUSSION…A LINE OF TSTMS HAS GRADUALLY STRENGTHENED ACROSS
NRN/WRN AL EARLY THIS MORNING WHILE THUS FAR REMAINING BELOW SVR
LIMITS. THE LINE IS IN ADVANCE OF AN EWD-MOVING COLD FRONT IN A
STRONGLY SHEARED AND MODESTLY UNSTABLE ENVIRONMENT AS SAMPLED BY THE
06Z BMX SOUNDING. HIGH-RESOLUTION GUIDANCE…INCLUDING THE NSSL WRF
AND HRRR…SUGGESTS THE LINE WILL CONTINUE MOVING EWD THROUGH THE
EARLY MORNING HOURS WITH A RISK FOR DAMAGING WINDS AND ISOLATED
EMBEDDED QLCS TORNADOES. LATEST RADAR REFLECTIVITY TRENDS INDICATE
SHOWERS DEVELOPING IN ADVANCE OF THE LINE OF TSTMS…AND THE
STRONGER UPDRAFTS WOULD POSE SOME RISK OF DEVELOPING LOW-LEVEL
CIRCULATIONS GIVEN THE STRONG LOW LEVEL AND DEEP LAYER SHEAR IN
PLACE.
A NEW TORNADO WATCH IS BEING CONSIDERED THAT WOULD INCLUDE AREAS TO
THE EAST AND SOUTH OF THE LINE IN WW 587 AND ALSO SRN PORTIONS OF WW
588.
