AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
950 AM CDT FRI MAY 19 2000

LOOKS LIKE 00Z AVN VERIFIED THE BEST WITH THE EXTENT OF
MID-LVL MOISTURE THIS MORNING OVER NRN ALABMA, AND THE 12Z ETA
HAS MADE APPROPRIATE ADJUSTMENTS AS WELL. IN ADDITION, 12Z ETA
NOW SWINGS BAND OF 80-90% RH AT 700MB NWD ACROSS ALL OF OUR
AREA TODAY, WITH POS UVVS OVER AT LEAST THE SRN 1/2 OF OUR COUNTIES.
DUE TO THE MORE EASTWARD EXTENT OF PRECIP, IT LOOKS LIKE OUR
SERN COUNTIES WILL NOW HAVE A THREAT OF RAIN SIMILAR TO OUR
SWRN COUNTIES. THUS, WILL PROBABLY BUMP POPS UP OVER ALL OF OUR
SOUTHERN COUNTIES INTO THE LIKELY CATEGORY FOR TODAY, WHICH WILL
ALSO MERGE WELL WITH MRXS NEW AFTERNOON FCST.

FOR NOW, WILL LEAVE POPS IN CHC CATEGORY OVER THE NORTH.

DONT EXPECT MORE THAN A 5 TO 8 DEG TEMP RISE TODAY, AS CLOUDS
AND N-NWLY SFC FLOW TAKE THEIR TOLL. WILL PROBABLY SHAVE 1ST
PD TEMPS BACK JUST A BIT OVER THE NORTH, BUT LEAVE THEM AS THEY
ARE OVER THE SOUTH, WHERE READINGS ARE ALREADY IN THE UPPER
60S.

.BNA...NONE.
