AREA FORECAST DISCUSSION
NWS GRAY ME
AFDGYX 817 PM EST FRI JAN 28 2000
NO SIG CHANGES TO THE FCST FOR THIS UPDATE.
WV LOOP SHOWS THE UPPER TROF MOVG THRU THE FA ATTM...WITH THE BACK
EDGE (AND THE DVV/S) ENTERING SERN QUEBEC. INVERSIONS ALREADY
LOWERING (AS EVIDENCED BY THE 2-3KFT INVERSION TOPS ON THE 28/00Z
RAOB...AS WELL AS THE KPWM/KMHT ACARS SOUNDINGS BETWEEN 2200-
0045Z). WUD EXPECT THE LOWERING INVERSIONS TO CUT OFF THE 20-30 KT
WINDS JUST ABV THE INVERSION...SO THE GUSTY WINDS SHUD CONT TO
DIMINISH. SINCE THE BEST GRAD IS OVER THE FA NOW...WUD EXPECT
WINDS TO DROP BLO 10 KT FM W TO E AFT MIDN.
SINCE THE WINDS WL DROP OFF...WL LIKELY HOLD OFF ON ANY MENTION OF A
WIND CHILL ADVISORY. WL PROBABLY BE BORDERLINE THRU ABT MIDN...
ESP OVER ERN ZNS WHERE THE GRAD WL EXIT LAST. WL WATCH OBS THRU 9
PM...BUT DON'T ANTICIPATE RAISE THE ADVISORY ATTM.
THE LOWERING INVERSION MAY TRAP SUM OF THE CLDS IN THE MTNS A LTL
LONGER...SO WL BACK OFF MENTION OF CLEARING TIL AFT MIDN. HOWEVER...
WITH SLACKENING WINDS AND DRYING IN THE LOWER AMS IN THE WAKE OF THE
UPPER TROF...WUD EXPECT THAT -SHSN ACTIVITY SHUD JUST ABT BE OVR
CANADIAN RADAR MOSAIC SUPPORTS THIS...SO UNLESS OBS SHOW REASON...
WL LIKELY LEAVE MENTION OF -SHSN OUT AS WELL.
AS THE UPPER LO MOVS EWD...MOST OTHER ZNS SHUD SEE WHATEVER MID/HI
CLDS THEY HAVE DISAPPEAR...SO M/CLR OR BECOMING M/CLR SHUD BE OK.
TEMPS MAY BE A BIT TUFFER TO FCST...SINCE DWPTS ARE COLD ENUF (EVEN
ALG THE CST) TO DROP MINS A FEW DEGREES. MUCH WL DEPEND ON HOW
QUICKLY THE WINDS DROP OFF. MAY LOWER MINS ALG THE CST (AS WELL
AS THE MTNS...WHERE TEMPS ARE ALREADY GETTING CLOSE TO THE HIGHER
END OF THE MIN RANGE)...BUT ELSEWHERE THE FCST MINS SHUD BE OK.
NO CHANGES TO THE REMAINDER OF THE FCST.
ON THE COASTAL WATERS...WINDS ARE ALREADY IN THE STG SCA REALM...AND
THE CURRENT FCST HANDLES THIS WELL.
PRELIM WRKZFP/WRKCWF. AS ALWAYS...COMMENTS/OPINIONS WELCOME.
