AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
950 PM EST SUN DEC 4 2005

.SHORT TERM (REST OF TONIGHT)...

CURRENT FCST OK...NO UPDATE NEEDED. NOT A LOT OF FLURRIES/SNOW
SHOWERS...BUT STILL A FEW N PA...AND MORE CLDS ARE COMING OFF
ERIE...THUS WILL LEAVE MENTION OF SNOW SHOWERS AND FLURRIES IN FCST.

SOME CONCERN ABOUT SE PART OF CWA FOR LATE MONDAY INTO EARLY
TUE...AS ENSEMBLE DATA SHOWS SOME RISK OF GETTING .5 INCHES OF
PCPN. FOR NOW...WILL LEAVE FCST AS IS...2 TO 4 INCHES...IF
SLIGHTLY MORE CAME...IT WOULD BE ON EDGE OF OF AREAS LIKE SE
YORK...S LANC. COUNTIES. NEW ETA IS SLIGHTLY FURTHER S AND E.

MID SHIFT CAN LOOK NEW GFS OVER...AND ADJUST MORE. LOOKS LIKE MOST
OF THE SNOW WOULD FALL IN A 6 HOUR PERIOD OR LESS...MAINLY MONDAY
EVENING...TAPERING OFF TUE AM.

LOOKING LONGER OUT...SOME LAKE EFFECT POSSIBLE...BUT LIKE
WED...INSTEAD OF LATE MONDAY...EARLY TUE...THUS NO NEED FOR
WATCHES ACROSS THE NW YET.

HUDSON BAY LOW LOOKS LIKE IT WANTS TO DRIFT WESTWARD...A
COMPLICATED AND PERHAPS ACTIVE PATTERN FOR EARLY DEC...PLENTY OF
COLD AIR AROUND. HOWEVER...REST OF THIS WEEK LOOKS FAIRLY
DRY...OUTSIDE THE LAKE EFFECT AREAS.

TEMPS WILL REMAIN BELOW NORMAL.

.PREVIOUS DISCUSSION...
(ISSUED 246 PM EST SUN DEC 4 2005)

SHORT TERM (TONIGHT THROUGH MONDAY)...

FRONT MOVING THROUGH CWA WILL BRING ONE LAST ROUND OF SHSN TO THE
AREA...THEN EXPECT SLOWLY IMPROVING CONDITIONS OVERNIGHT. A FEW
BREAKS MAY DEVELOP OVERNIGHT AND EARLY TOMORROW BEFORE CLOUDS FROM
THE NEXT APPROACHING SOUTHERN STREAM SYSTEM APPROACH. NAM AND GFS
STILL IN DISAGREEMENT ON THE TRACK AND EXTENT OF SIGNIFICANT PCPN
INTO CENTRAL PA. BASED ON WWD DISC AND CONFERENCE CALL...ATTM ARE
THINKING THAT SNOW WILL BE BELOW WINTER STORM CRITERIA FOR THE CWA.
SREFS DO HOWEVER SHOW THAT ALMOST HALF THE MEMBERS BRING HIGH
ADVISORY SNOW AMOUNTS UP TO UNV FROM THE SOUTH AND EAST. WILL
MONITOR NEXT MODEL RUNS...BUT ATTM WILL NOT BE ISSUING A WATCH.

LONG TERM (MONDAY NIGHT THROUGH SUNDAY)...
MOST EXCITING WEATHER IS IN THE FIRST PART OF THE SHORT TERM
FORECAST PERIOD...HOWEVER AS MON SYSTEM MOVES OFF TO THE EAST. ON
TUE FLOW COMES OFF THE LAKES AND SNOW BEGINS AGAIN IN THE
NORTHWEST CWA. ALTHOUGH THIS TIME AMOUNTS SHOULD BE LOWER AND NOT
EVEN REACH ADVISORY CRITERIA. COLD HIGH FILTERS IN FROM THE NORTH
AND WEST DURING THE MIDDLE PART OF NEXT WEEK AND AND SOME SNOW
SHOWERS ARE CERTAINLY POSSIBLE INTO WEDNESDAY. HIGH SETTLES OVER
THE CENTRAL PORTION OF THE US ON WED NIGHT/THURSDAY AND KEEPS US
PRECIP FREE INTO THE WEEKEND.
