Severe Thunderstorm Warning 8, NWS Nashville, TN

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
225 PM CST SUN MAR 8 1998

LATEST KGWX REFLECTIVITY PICS SHOWS RAPIDLY DEVELOPING ALONG LOW LEVEL
BOUNDRY IN AL INTO SW MIDDLE TN. THUS...WOULD NOT DUMP OVERBOARD THE
IDEA THAT THUNDERSTORMS WILL BE WITH US INTO THE EVENING HOURS. IN
FACT...WITH UPPER LEVEL JET SURGING ACROSS OUR AREA...THERE COULD ALSO
BE A FEW SEVERE THUNDERSTORMS AS WELL.

NGM/ETA SIMILAR IN PROGRESSION OF SURFACE LOW TO OHIO VALLEY
REGION AND UPPER LEVEL LOW TO NE ARKANSAS BY THIS EVENING. WITH COLD
POOL AND HIGH TT/K VALUES EXPECTED...BELEIVE PREFRONTAL TROUGH WILL
PROVIDE NEEDED FORCING MECHANISM FOR THUNDERSTORM ACTIVITY...WITH
SOME OF THESE STORM REACHING SEVERE THRESHOLDS. WOULD ADVISE CAT POPS
OVER WESTERN MIDDLE TN THRU 06Z MON. WOULD RECOMMEND LIKELY POPS
ELSEWHERE.

AFTER 06Z MON...LOOK FOR CAA TO PLAY QUITE A ROLE IN CWA WX SCENARIO.
WITH RESIDUAL MOISTURE LEFT BEHIND AND TEMPERATURES EXPECTED TO DROP
30 DEGREES FROM TODAYS HIGHS...THERE IS A POSSIBILITY OF SNOW FLURRIES
FROM WEST TO EAST OVER CWA AFTER 18Z ON MONDAY AS COLD FRONT FINALLY
PUSHES THROUGH AREA. HIGHS FOR MONDAY WILL PROBABLY BE SET IN THE
EARLY MORNING HOURS AND DROP THRU THE DAY...LEADING TO A CHILLY MONDAY
NIGHT. TUE WILL BE DOMINATED BY CANADIAN HIGH PRESSURE SYSTEM MOVING
INTO REGION. WILL GO CLOSER TO MOS NUMBERS FOR MON NIGHT AND TUESDAY.
