WV IMAGERY SHOWING CIRRUS COVERING CWA AND THICKENING WITH TIME AND
LOWER MID DECK PUSHING INTO SOUTHERN KENTUCKY ATTM.  A LITTLE BIT
MORE OF A PRESSURE GRADIENT AT THE SFC THIS EVENING AS WELL THAN

STEADY OVER THE PAST COUPLE OF HOURS.  WITH A BIT MORE WIND AND
CLOUDS WILL ADJUST TEMPS UP A TAD WEST OF THE MTNS.  OTHERWISE
FORECAST LOOKS TO BE ON TRACK.

345 PM EST TUE DEC 3 2002

TUESDAY NIGHT THROUGH THURSDAY...
WITH SYSTEM COMING IN THE TRICK IS FREEZING RAIN AND SLEET VS SNOW.
IN SW VA COUNTIES AND WYOMING/MCDOWELL THE SOUNDING ON BOTH ETA AND
AVN SHOWS BORDERLINE CONDITIONS FROM LATER WEDNESDAY AFTERNOON INTO
WEDNESDAY NIGHT.  THE THREAT OF BOTH ICE AND SNOW PROMPTED THE
WARNING FOR THESE COUNTIES FOR LATER IN THE AFTERNOON AND NIGHT.  IN
THE MOUNTAINS THE HEAVIER PRECIPITATION WILL NOT BE GETTING INTO THE
MOUNTAINS UNTIL WEDNESDAY NIGHT SO WILL KEEP THE WATCH THERE.  THE
INCREASE IN ELEVATION SHOULD MAKE IT ALL SNOW IN THE MOUNTAIN
COUNTIES.  WEST OF THE MOUNTAINS SHOULD BE ALL SNOW AND AMOUNTS NEAR
ADVISORY NEARER THE MOUNTAINS ARE EXPECTED WITH ONLY LIGHT AMOUNTS
FROM AROUND THE OHIO RIVER WEST.  FLOW TURNS WESTERLY QUICKLY
THURSDAY SO HAVE CUT OFF PRECIPITATION BY MID DAY.

THURSDAY NIGHT THROUGH TUESDAY...
ANY REMAINING PRECIPITATION IN THE NORTHERN MOUNTAINS WILL TAPER OFF
ON THURSDAY NIGHT AS A HIGH PRESSURE SYSTEM BEGINS BUILDING ACROSS
THE REGION. THIS HIGH WILL PROVIDE DRY WEATHER FOR FRIDAY AND
SATURDAY. A COLD FRONT WILL THEN PROVIDE A CHANCE OF RAIN OR SNOW ON
SUNDAY AS IT PUSHES ACROSS THE AREA. MRF NOW SHOWS MONDAY DURING THE
DAY AS DRY WITH LOW PRESSURE MOVING SOUTH OF THE AREA MONDAY NIGHT
AND TUESDAY. THIS SCENARIO LOOKS VERY SIMILAR TO WEDNESDAY
NIGHT...BUT WILL NOT GO THAT STRONG SINCE DAY SEVEN.

.RLX...
WV...WINTER STORM WARNING 4PM WEDNESDAY THROUGH 8AM THURSDAY MORNING
FOR ZONES WVZ033-034.

*********************************************************************
1000 AM EST TUE DEC 3 2002

ON LATE MORNING UPDATE WILL BE MAKING TWO SIGNIFICANT CHANGES.  MAX
TEMPERATURES FOR THIS AFTERNOON WAY TO HIGH.  LOWERING MAX
TEMPERATURES 6 TO 8 DEGREES.

ADDING A WINTER STORM WATCH FOR WEDNESDAY NIGHT FOR SNOW IN THE
MOUNTAINS AND MIXED BAG OR SNOW IN SW VA AND TWO WEST VIRGINIA
COUNTIES BETWEEN SW VA AND MOUNTAINS.  MODELS IN AGREEMENT FOR
POTENTIAL WARNING CRITERIA SNOWFALL IN WATCH AREA.  WILL HOLD OFF TO
THE WEST OF THE MOUNTAINS BECAUSE THE ISENTROPIC LIFT IS CLEAR EAST
OF THE MOUNTAINS BUT NOT AS CLEAR TO THE WEST.  WILL WAIT FOR NEW
MODEL RUNS FOR DOING ANYTHING TO THE WEST.

400 AM EST TUE DEC 3 2002

TODAY AND TONIGHT...

A COLD DOME OF HIGH PRESSURE BUILDS INTO THE REGION TODAY...ALONG
WITH COLD ADVECTION AND THE DECREASING CLOUDS AND THE LACK OF PCPN
WILL INCREASE THE HIGHS TEMPS AREAWIDE TODAY...AND UP THE LOW TEMPS
OVERNIGHT DUE TO AN INCREASING MOISTURE.  LIGHT TO MODERATE
NORTHEAST WINDS WILL KEEP A CHILL IN THE REGION TODAY.

WEDNESDAY THROUGH MONDAY...
TRIED TO SLOW DOWN THE ONSET OF GULF MOISTURE.  BELIEVE IT WILL TAKE
A LITTLE LONGER FOR THE ATMOSPHERE TO MOISTEN UP AFTER THE PAST
COUPLE DRY DAYS.  INCREASED POPS...AND WILL GIVE THE IDEA OF
ISSUING A WATCH FOR WINTER WEATHER TO THE DAY SHIFT.  LATEST MODELS
ARE INDICATING THE POSSIBILITY OF MIXED PRECIPITATION DURING THE
ONSET...BUT BELIEVE THAT THIS WILL BE FURTHER SOUTH.  HOWEVER...THIS
THINKING MAY CHANGE THE CLOSER WE GET TO THE EVENT.  KEPT MUCH OF
THE REMAINDER OF THE FORECAST SIMILAR TO THE PREVIOUS ISSUANCE...DID
TWEAK TEMPS A BIT TOO.
