The storm chase season has offically begun. A trough system continues to make its way eastward into the plains. It looks like there may be enough moisture in the afternoon for severe potential. As a result, there is a slight risk today for north west Texas and for western Oklahoma. The tornado risk is currently at 2% for that area. Central Texas also has a chance for some severe weather as well.
The SPC said this:
THREAT OF SEVERE THUNDERSTORMS APPEARS TO BE WARRANTED GIVEN THE SOMEWHAT BETTER MOISTURE AND INSTABILITY THAN EARLIER EXPECTED.
THE SLIGHT RISK HAS BEEN EXPANDED SWD ACROSS WRN OK INTO NWRN TX...PRIMARILY FOR THE HAIL THREAT...HOWEVER ISOLATED SUPERCELLS ARE POSSIBLE WITH THE POTENTIAL FOR A BRIEF TORNADO AND/OR DAMAGING WINDS.
Moderate risk today, 12-24-09, for Gulf Coast States
The slight risk has been upgraded to a moderate risk for today for LA and MS, but a slight risk remains for the other gulf coast states. The tornado risk for the area is currently at 15%. The area is also currenlty under a tornado watch as a squall line makes its way eastward.
The SPC said this: SHEAR PROFILES ALREADY VERY FAVORABLE FOR TORNADIC SUPERCELLS ALONG AND AHEAD OF THE N/S SQUALL LINE NOW MOVING EWD ACROSS LWR MS VALLEY. IT NOW APPEARS THAT THE 50-60KT LOW LEVEL JET OFF THE GULF WILL PROVIDE SUFFICIENT LOW LEVEL MOISTURE AND INSTABILITY TO SUPPORT A CONTINUED THREAT OF TORNADIC SUPERCELLS EWD ACROSS SERN LA/SRN MS INTO AT LEAST SWRN AL BY THIS EVENING.
Slight Risk 12-23-09 today for East TX and West LA.
There is a slight risk today for north east Texas and for West LA. There is currently a tornado Watch for the area. Damaging winds are the main risk but there is also a 10% chance for Tornadoes.
The SPC said this: THE ENTIRE WIND PROFILE WILL IMPROVE WITH TIME THIS AFTERNOON INTO TONIGHT AS STRONGER WIND FIELD ATTENDANT TO UPSTREAM SYSTEM OVERSPREADS THE REGION. GIVEN THE MOISTENING BOUNDARY LAYER...WEAKENING CIN AND RESULTANT MLCAPE OF 500-1000 J/KG...SETUP WILL BECOME INCREASINGLY FAVORABLE FOR SUPERCELLS EMBEDDED IN LARGER CONVECTIVE SHIELD WITH THE THREAT FOR TORNADOES...HAIL AND DAMAGING WINDS.
