AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1120 PM CST FRI NOV 20 2009
.UPDATE...FOR 06Z TAFS/AVIATION DISCUSSION &&
.AVIATION...EVEN WITH GENERAL CLOUDINESS INCREASING ACROSS THE AREA FROM THE SW...CEILINGS ARE XPCTED TO REMAIN ABOVE VFR LIMITS THROUGH THE FORECAST PERIOD. RAIN/SHOWERS ARE ALSO XPCTED TO APPROACH THE TN VALLEY FROM THE SW STARTING AROUND 00Z SUN...BUT PRECIP COVERAGE IS NOT XPCTED TO INCREASE SIG UNTIL 06Z OR LATER. &&
.DISCUSSION...CLOUD COVER OUT OF THE SW CONTINUES TO GRADUALLY MAKE ITS WAY INTO THE TN VALLEY THIS EVENING. THE AREA OF LOW PRESSURE IN THE WRN GULF HAS MOVED LITTLE OVER THE PAST FEW HRS...ALTHOUGH MODEL GUIDANCE STILL INDICATES THIS SYSTEM BEGINNING TO DRIFT TOWARD THE NE OVERNIGHT...AND THEN TURNING MORE EWD DURING THE DAY SAT. THIS SHOULD ALLOW CLOUDINESS TO CONTINUE INCREASING ACROSS THE AREA WITH RAIN/SHOWERS THEN MOVING INTO THE TN VALLEY LATE SAT AFTERNOON AND EVENING. IN THE MEANTIME...WITH THE ONCOMING CLOUD COVER...OVERNIGHT LOWS MAY BE TRICKY ALTHOUGH CURRENT DEW PT READINGS SUGGEST TEMPS SAT MORNING HOVERING A FEW DEGREES ABOVE XPCTED DEW PT VALUES GIVEN SKIES BECOMING MOSTLY CLOUDY. CURRENT FORECAST SEEMS TO HAVE THESE TRENDS REPRESENTED WELL AND NO UPDATES ARE PLANNED AT THIS POINT. &&
.HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. &&
