NWS Huntsville, AL wrote its last area forecast discussion before the first event at Apr 3, 10:12 AM CST, 25 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1112 AM CDT TUE APR 3 2007 .UPDATE... ADJUSTING HIGH TEMPS UP A COUPLE OF DEGREES FOR WRN ZONES. && .DISCUSSION... ANALYSIS REVEALS SFC LOW PRESSURE IS CENTERED OVER THE UPPER MIDWEST WITH A COLD FRONT EXTENDING SW ACROSS MO AND INTO NRN TX. THE AIRMASS IN THE WARM SECTOR IS RATHER UNSTABLE WITH DEWPTS IN THE 60S ACROSS THE LOWER/MID MS AND TN VALLEYS. A WEAK CAP REMAINS IN PLACE...BUT IT IS QUICKLY BEING ERODED AS TEMPS WARM INTO THE MID 70S. A WEAK S/W KICKED UP A COUPLE OF ISOLATED TSTMS...WHICH QUICKLY DEVELOPED ACROSS NERN MS AND MOVED NE INTO NRN AL. INTERESTINGLY...SOME MAMMATUS CLOUDS UNDER THE ANVIL OF THE STORM TO THE WEST WERE SEEN HERE AT THE NWS OFFICE IN HUNTSVILLE. SO THERE DEFINITELY IS SOME STRONG MID LEVEL SHEAR PRESENT. 12Z SNDINGS INDICATE LOW LEVEL SHEAR WAS QUITE UNIDIRECTIONAL THUS FAVORING SPLITTING STORMS...WHICH HAS ALREADY OCCURRED WITH THE STORMS MOVING ACROSS THE AREA ATTM. AS TEMPS CONTINUE TO WARM INTO THE 80S TODAY...ADDITIONAL ISOLATED TO SCATTERED TSTORMS MAY DEVELOP...BUT NOT REALLY SEEING ANY SIGNIFICANT S/W TROFS UPSTREAM. SO ADDITIONAL TSTORMS WILL PROBABLY NOT BE UNTIL LATER THIS AFTERNOON NEAR THE PEAK OF THE DIURNAL TEMP CURVE. FCST SNDINGS SUGGEST LOW LEVEL HODOGRAPHS WILL BECOME MORE CURVED THIS AFTERNOON AS THE FRONT MOVES CLOSER AND WINDS BACK IN RESPONSE. THUS MORE ORGANIZED CONVECTION IN THE FORM OF SUPERCELLS ARE THE MORE PROBABLE STORM TYPE THIS AFTERNOON. LOW AND MID LEVEL LAPSE RATES ARE STILL EXPECTED TO BE RATHER STEEP AND THUS LARGE HAIL AND DAMAGING WIND GUSTS ARE A POSSIBILITY. FORTUNATELY 0-1KM SHEAR DOES NOT APPEAR TO BE VERY FAVORABLE FOR TORNADOES THIS AFTERNOON. SINCE TEMPS HAVE WARMED INTO THE MID 70S ACROSS THE TN VALLEY AND THERE IS LESS CLOUD COVER OVER NWRN AL...WILL RAISE HIGH TEMPS A FEW DEGREES. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. && PG
