AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
642 PM EST THU DEC 6 2007
.SYNOPSIS...
AN UPPER LEVEL DISTURBANCE WILL SWING INTO THE OHIO VALLEY
TONIGHT...PRODUCING ANOTHER SHOT OF SNOW AND MIXED PRECIPITATION.
THE SYSTEM WILL PULL OUT QUICKLY FRIDAY AFTERNOON. A WARM FRONT
WILL PUSH INTO THE REGION FRIDAY NIGHT INTO SATURDAY AND WILL
STALL ACROSS THE AREA FOR MUCH OF THE PERIOD. THIS WILL KEEP THE
CHANCE OF PRECIPITATION IN THE FORECAST THROUGH THE NEAR FUTURE.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
H5 SHORTWAVE SWINGING OUT OF THE MID MS VALLEY WILL COMBINE WITH
ISENTROPIC LIFT TONIGHT TO BRING ANOTHER SHOT OF PCPN. ONCE AGAIN
THE MODELS DIFFER GREATLY ON THE STRENGTH...TIMING AND LOCATION OF
THE PCPN. 12Z NAM AND NGM ARE FARTHER NORTH THAN THE GFS...ALMOST
LEAVING THE EXTREME S DRY. I SEE THE 18Z NAM IS NOW FARTHER S
SIMILAR TO THE GFS. PREFERRED THE GFS SOLUTION FROM THE ONSET.
GFS IS SHOWING OK ISENTROPIC LIFT ON THE I285 SURFACE. AT 06Z THE
FLOW ISNT QUITE CROSS CONTOUR...BUT IT IMPROVES BY 12Z. WARM AIR
WORKS IN ON THE SOUTH SIDE OF THE SYSTEM AND SHOULD PRODUCE MIXED
PCPN ACROSS KY INTO SE OH. LOOKS LIKE THE
EXPECT LOWS TO OCCUR EARLY TONIGHT...THEN RISE LATE. AFTER BEING
WAY TOO WARM. LOWS LAST NIGHT WENT WITH THE COLD FWC GUIDANCE.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/...
PCPN FROM S/W WILL AFFECTING THE FA AT THE BEGINNING OF THE
PERIOD. 12Z NAM/NGM WERE SLOWER IN EXITING THE PCPN...BUT
PREFERRED THE QUICKER GFS. ISENTROPIC LIFT WORKS E QUICKLY AND ALL
PCPN SHOULD HAVE CLEARED THE AREA BY 18Z.
WRMFNT THEN DEVELOPS IN THE TN VLY INTO SRN OH VLY FRI NGT. ONCE
AGAIN LEANED TOWARDS THE GFS/ECMWF SOLUTION WHICH SPREADS PCPN
FARTHER N THAN THE NAM/NGM. TEMPS SHOULD JUST BE WARM ENUF FOR THE
PCPN TO FALL AS RA IN THE S...WHILE THE N WILL EXPERIENCE SNOW.
FNT GRADUALLY LIFTS N...AND IS LOCATED JUST S OF THE FA BY 12Z
SAT. WARM AIR WILL GRADUALLY WORK N ON SATURDAY AND SHOULD CHANGE
THE SN IN THE N INTO RA. FNT DOESNT REALLY WORK MUCH FARTHER N
THRU THE PERIOD...BUT LIFT ACROSS THE FNT KEEPS PCPN THRU THE
PERIOD. DEPENDING ON WHERE THE FNT ENDS UP...THE NRN COUNTIES
COULD STAY ALL SNOW...ITS THAT CLOSE.
WITH THE PCPN AND SNOW COVER IN THE FORECAST THRU THE
PERIOD...TEMP FORECAST IS TRICKY. GENERALLY TRIED TO STAY AT THE
COOL END OF GUIDANCE.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
PATTERN DOESNT CHANGE MUCH IN THE EXTENDED. THE FRONT REMAINS
HUNGUP OVER THE S...AND MOISTURE SURGES N. NRN COUNTIES REMAIN ON
THE EDGE OF THE RA/SN LINE. MODELS DIVERGE WITH THEIR SOLUTIONS
AS GFS EJECTS A STRONG S/W OUT THE W COAST H5 TROF ON TUE...PRODUCING
A CLOSED SFC LOW...WHICH RUNS THROUGH THE WRN OH VLY. THIS IS NOT
SHOWN ON THE MEDIUM RANGE ENSEMBLE OR THE ECMWF. AS THIS LOW
PUSHES NORTHEAST...IT FINALLY DISLODGES THE FNT...ALLOWING COLDER
AIR TO WORK IN. BACKED A WAY FROM THE GFS SOLUTION AND TRIED TO
DELAYED THE PUSH OF COLD AIR. FOLLOWED HPC TEMPS IN THE EXTENDED.
&&
.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
CLOUD COVER WILL INCREASE QUICKLY THIS EVENING AHEAD OF A WARM
FRONTAL FEATURE APPROACHING FROM THE PLAINS. THERE ARE SOME TIMING
DIFFERENCES...BUT IT APPEARS THAT ACCUMULATING SNOW WILL
OVERSPREAD THE TERMINALS WEST TO EAST 07Z-10Z...LASTING 3 TO 5
HOURS AT A GIVEN TERMINAL. KLUK AND KCVG COULD SEE A WINTRY MIX
09Z-12Z.
CIGS WILL BECOME MVFR AND THEN LIFR QUICKLY WITH THE
PCPN...BECOMING MVFR 14Z-18Z...AND PERHAPS VFR AT KCVG.
OUTLOOK...MVFR CIGS AND VSBYS POSSIBLE FRIDAY NIGHT INTO TUESDAY DUE
TO RAIN.
