Storm Prediction Center Severe Weather Outlook for Tuesday
Projected helicity values at noon Tuesday
Projected helicity values Tuesday at 6 p.m.
Excerpt from NWS Birmingham's HWO:
THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORMS ACROSS ALL OF
CENTRAL ALABAMA TUESDAY...ESPECIALLY BETWEEN NOON AND 10 PM. THE
GREATEST THREAT WILL BE FROM DAMAGING WINDS ASSOCIATED WITH BOW
ECHOES. TORNADOES WILL ALSO BE POSSIBLE WITH THE STRONGER
STORMS. The Storm Prediction Center has placed Central and South Alabama under a slight risk for severe weather on Tuesday. Dew points will be between 60 and 65 in these areas but instability will be limited. However, vertical shear values may be rather strong.Here is an excerpt from their outlook:
FORECAST HODOGRAPHS INDICATE THAT VERTICAL SHEAR /BOTH THROUGH A DEEP LAYER AND IN THE LOW LEVELS/
WILL BECOME QUITE STRONG OWING TO COLLOCATION OF 50-60 KT SWLY LLJ AND 80-100+ KT SWLY MIDLEVEL FLOW.
AS SUCH...THE POTENTIAL WILL EXIST FOR EMBEDDED SUPERCELL AND BOWING STRUCTURES CAPABLE OF DAMAGING
WINDS AND POSSIBLY A FEW TORNADOES.

Are you going to be able to get out? A little SDS Rx early in 2009.

Not unless it is relatively close. I used up a lot of leave over the holidays.
