AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1019 AM CDT WED JUL 29 2015 .UPDATE...TO DROP HEAT ADVISORY AND RAISE POPS. && .DISCUSSION... THE ATMOSPHERIC COLUMN IS EVEN MORE SATURATED TODAY OVER THE TENNESSEE VALLEY. THIS IS DUE TO A NORTH TO SOUTH ORIENTED CONVERGENCE BOUNDARY WHICH STRETCHES FROM CENTRAL TN SOUTH INTO NORTHERN AL. SCATTERED TO MORE NUMEROUS SHOWERS AND THUNDERSTORMS HAVE ALREADY BEEN FORMING THIS MORNING ALONG AND WEST OF THIS BOUNDARY IN NW AL ESPECIALLY. MORE ACTIVITY CAN BE SEEN UPSTREAM IN SOUTHERN TN...WHICH WILL PUSH INTO NW AL LATER THIS MORNING. BASED ON THE EXPECTED ATMOSPHERIC FLOW PROGGED BY MODELS...BELIEVE MOST OF THIS ACTIVITY WILL PUSH INTO PRIMARILY NW AL AND LOCATIONS NEAR THE I-65 CORRIDOR THROUGH AROUND NOON OR 1 PM. THEN EXPECT SCATTERED ACTIVITY TO DEVELOP FURTHER EAST DURING THE AFTERNOON HOURS...WHERE MORE BREAKS IN CLOUD COVER AND BETTER INSOLATION HELP CONVECTIVE DEVELOPMENT. EXPECT THE BOUNDARY TO MOVE SLIGHTLY WEST AS THE DAY PROGRESSES...BUT NOT MUCH. THE GOOD NEWS IS THAT THE CLOUD COVER AND ACTIVITY THIS MORNING WILL HELP TO STABILIZE THE ATMOSPHERE LATER THIS AFTERNOON IN NW ALABAMA. ALSO THIS WILL KEEP HIGH TEMPERATURES LOWER THAN PREVIOUSLY EXPECTED.

ADDITIONAL SHRA ARE CURRENTLY DEVELOPING IMMEDIATELY E OF HSV BUT WILL LIKELY MISS THE TERMINAL. IR SATELLITE IMAGERY SUGGESTS A FAIRLY RAPID EROSION OF AS/CS CLOUDS WILL OCCUR FROM THE NE EARLY IN TAF PERIOD...ALLOWING AN INCREASINGLY UNSTABLE AIRMASS TO SUPPORT HIGHER THREAT FOR TSRA BTWN 15-00Z. AFTER A BREAK THIS EVENING...ANOTHER ROUND OF SHRA/TSRA IS EXPECTED TO DEVELOP ALONG COLD FRONT ADVANCING SEWD THRU MID TN. SOME OF THIS ACTIVITY MAY APPROACH THE TERMINALS BY END OF TAF PERIOD...BUT UNCERTAINTY TOO GREAT TO INCLUDE VCTS ATTM. OUTSIDE OF CONVECTION...EXPECT A CONTINUATION OF SCT CU BENEATH BKN MID/HIGH CLOUDS. SFC WINDS WILL REMAIN FROM THE NW AT 5-10 KTS TODAY...BUT WILL VEER TO NNE OVERNIGHT. 70/DD && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
