414 AM EDT THU OCT 24 2013
.SHORT TERM /TODAY THROUGH TONIGHT/...
MAIN STORY THROUGH THE SHORT TERM REMAINS THE UNSEASONABLY COOL
TEMPERATURES. DEEP UPPER LOW CONTINUES TO DOMINATE THE EASTERN HALF
OF THE COUNTRY...WITH A SHORTWAVE DIVING DOWN THE NORTHWEST FLOW TO
BRING A SLIGHT INCREASE IN MID-LEVEL MOISTURE TO NORTH GEORGIA THIS
MORNING AND EARLY AFTERNOON. WEAK SURFACE HIGH WILL REMAIN IN PLACE
OVER THE SOUTHEAST TODAY WITH THE STRONGER...COLDER HIGH COMING DOWN
THE NORTHWEST FLOW INTO THE CENTRAL PLAINS TODAY. GUIDANCE IN FAIRLY
GOOD AGREEMENT THROUGH THE SHORT TERM...THOUGH MET TEMPS ARE A BIT
COOLER THAN MAV WITH THE ECMWF SORT OF BETWEEN THE TWO. WENT WITH A
BLEND BUT DID NOT USE AS MUCH BIAS CORRECTION BECAUSE OF THE AIRMASS
CHANGE.
FROST ADVISORY CONTINUES FOR THIS MORNING...AND IT SEEMS THAT SOME
ISOLATED AREAS IN THE MOUNTAINS MAY REACH FREEZING...BUT NOT ENOUGH
TO UPGRADE TO A FREEZE WARNING. MOST CLOUD COVER ASSOCIATED WITH THE
MIDLEVEL MOISTURE WILL REMAIN ACROSS EXTREME NORTHERN ZONES THIS
MORNING AND TODAY...BUT WITH SOME MOISTURE REMAINING TEMPS TONIGHT
PROBABLY WILL NOT GET QUITE AS COLD AS THEY WILL THIS MORNING. THAT
SAID...HAVE ISSUED ANOTHER FROST ADVISORY FOR FRIDAY MORNING BUT A
SMALLER AREA OF NORTH GEORGIA. SAME STORY WITH SOME ISOLATED AREAS
POSSIBLY REACHING FREEZING BUT NOT ENOUGH FOR FREEZE WARNING.
SURFACE HIGH WILL BE CENTERED OVER THE MID-SOUTH ON FRIDAY TO SHIFT
INTO THE SOUTHEAST FOR THE FIRST PART OF THE EXTENDED. HIGHS ON
FRIDAY WILL BE ANOTHER 6-8 DEGREES COOLER THAN HIGHS TODAY.
TDP
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
EXTENDED MODELS IN GOOD AGREEMENT THROUGH PERIOD. SURFACE HIGH
PRESSURE CENTERED OVER THE FORECAST AREA FRIDAY NIGHT WILL KEEP
WINDS NEAR CALM...AND WHEN COMBINE WITH EXPECTED CLEAR SKIES WILL
ALLOW GOOD RADIATIONAL COOLING TO SET UP. LOW TEMPERATURES
SATURDAY MORNING WILL DROP BELOW FREEZING NORTH OF A LA GRANGE TO
THOMSON LINE WITH A HARD FREEZE POSSIBLE IN PORTIONS OF NORTH
GEORGIA. ATHENS WILL APPROACH THE PREVIOUS RECORD LOW /SEE CLIMATE
PORTION BELOW/...AND HAVE GONE AHEAD AN ISSUED A FREEZE WATCH FOR
06-14Z SATURDAY /SEE ATLNPWFFC FOR MORE INFORMATION/. HIGH
PRESSURE AND DRY CONDITIONS WILL CONTINUE INTO EARLY NEXT WEEK AS
TEMPERATURES MODERATE BACK TOWARD NORMAL HIGHS/LOWS. THE NEXT
SYSTEM CONTINUES TO APPROACH BY THE END OF THE WEEK WITH
INCREASING MOISTURE ACROSS THE AREA BY MIDWEEK.
ATWELL
