Area forecast discussion, Jun 2, 3:41 AM EDT, 1 hour 27 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
340 AM EDT SUN JUNE 2 2002

TODAY AND TONIGHT...
COLD FRONT PUSHES SOUTHWARD TODAY WITH INSTABILITIES BY THIS
AFTERNOON ONLY OVER THE SOUTHERN COUNTIES. RATHER WELL DEFINED
VORTICITY LOBE THEN PUSHES OVER THE REGION TONIGHT. FEEL ANY
PRECIPITATION WOULD BE CONFINED TO THE SOUTHERN COUNTIES...BUT SINCE
PRECIPITATION IS ALREADY IN THE FORECAST AND MODELS HAVE BEEN
PUSHING FRONT TOO FAR SOUTH...WILL LEAVE MINIMUM POP TONIGHT ALL
AREAS.

EXTENDED RANGE (MON-SATURDAY)...OVERALL CONTINUED TREND OF PREVIOUS
FCST.  MODELS SEEM IN GOOD AGREEMENT THRU ABOUT 60 HRS.  THE TIMING
OF THE MOVEMENT OF THE WARM FRONT TO THE NORTH IS A LITTLE DIFFERENT
IN THE NGM/ETA/AVN.  TO ACCOUNT FOR THIS HAVE LEFT 30 POPS IN ACROSS
THE NRN PORTION OF THE CWA FOR MON NIGHT.  WARM AIR SURGES IN BEHIND
THE FRONT AND HAVE RAISED TEMPS A CAT ON TUESDAY IN LINE WITH THE
AVN GUIDANCE.  ALSO WARMED MINS TUES NIGHT AS FRONT REMAINS NORTH
AND WEST OF CWA SO MINS SHOULD BE SIMILAR TO MON NIGHT.

FROM WED ON THE FORECAST IS UNCHANGED AS THE MODEL UNCERTAINTY
CONTINUES.  THE AVN IS STILL THE MOST PROGRESSIVE WITH THE
SOUTHWESTERN TROF AND ENDS UP WITH A POSITIVELY TILTED TROF FROM THE
GREAT LAKES BACK INTO TX.  THE OTHER MODELS...ECMWF AND
CANADIAN...ALONG WITH THE 60 HOUR OF THE ETA/NGM...LEAVE A CUTOFF
TYPE FEATURE OVER THE SOUTHWESTERN US AND ALLOW NRN STREAM ENERGY TO
RUN OVER THE RIDGE THAT IS IN PLACE OVER THE CENTRAL AND
SOUTHEASTERN US.  INSTEAD OF HAVING A FRONT STALL IN THE SW FLOW
ACROSS THE REGION AS THE AVN SUGGEST...A NRN STREAM TROF SWINGS
THROUGH THE MID ATLANTIC STATES...WHICH DRIVES A SURFACE FRONT INTO
THE SOUTHEAST.  HIGH PRESSURE MOVES SOUTH OUT OF CENTRAL CANADA.
THIS WOULD BRING DRIER WEATHER AND COOLER TEMPERATURES.  AT THIS
POINT...WILL LEAVE THIS FOR THE DAY SHIFT AND WILL LET THEM
COORDINATE THIS WITH HPC AND OTHER ERN CLUSTER SITES.
