238 PM EST TUE MAR 14 2006

.SHORT TERM (TONIGHT THROUGH WEDNESDAY)...
GRADIENT REMAINS TIGHT SO GUSTY WESTERLY SURFACE WINDS WILL
CONTINUE. BUFKIT MOMENTUM TRANSFER SUGGESTS ADVISORY CRITERIA WIND
GUSTS CONTINUE INTO THE EVENING HOURS SO OUR WIND ADVISORY FOR THE
HIGHER ELEVATIONS EAST AND SOUTHEAST OF PITTSBURGH WILL REMAIN IN
PLACE TIL 10 PM THIS EVENING. MOSTLY CLOUDY OVERNIGHT WITH CYCLONIC
UPPER FLOW CONTINUING. SCATTERED SNOW SHOWERS/FLURRIES WILL PERSIST
WITH LIGHT ACCUMULATIONS POSSIBLE ACROSS OUR NRN ZONES AND IN THE
RIDGES EAST AND SOUTHEAST OF PITTSBURGH. BREAKS IN CLOUD COVER NOT
EXPECTED UNTIL DURING THE DAY ON WEDNESDAY AS SURFACE LOW PULLS OUT
TO THE NORTHEAST AND HIGH PRESSURE SLOWLY BUILDS IN FROM THE WEST.
TEMPERATURES WILL RUN 5 TO 10 DEGREES BELOW NORMAL.

&&

.LONG TERM (WEDNESDAY NIGHT THROUGH TUESDAY)...
CONCUR WITH HPC THINKING THAT RECENT GFS MODEL RUNS HAVE GOOD
HANDLE ON BUILDING UPPER LEVEL RIDGE ACROSS THE NORTHERN PLAINS
STATES LATE WEEK. RECENT ECMWF MODEL RUNS AND MOST GFS ENSEMBLE
MEMBERS SUPPORT THIS SCENARIO. THE NET RESULT IS A CONTINUED
INJECTION OF ENERGY FROM THE NORTHERN JET STREAM AND A
CORRESPONDING INFLUX OF COLDER CANADIAN AIR INTO THE UPPER OHIO
VALLEY. THIS WILL RESULT IN TEMPERATURES BEING COLDER THAN NORMAL
INTO EARLY NEXT WEEK.

AN EXTRATROPICAL CYCLONE EMBEDDED IN THIS JET STREAM WILL MOVE
SOUTHEASTWARD ACROSS THE UPPER OHIO VALLEY THURSDAY NIGHT INTO
FRIDAY, GENERATING SUFFICIENT LIFT TO CAUSE SHOWERS. DUE TO THE
COLDNESS OF THE ENTIRE AIR COLUMN, THE MAIN PRECIPITATION TYPE
WILL BE SNOW. DUE TO LIMITED MOISTURE AVAILABILITY, PRECIPITATION
AMOUNTS WILL BE LIGHT.

AS THE PLAINS RIDGE MOVES EASTWARD INTO THE OHIO VALLEY THIS
WEEKEND, DRY CONDITIONS WILL PREVAIL INTO EARLY NEXT WEEK.

&&

.AVIATION...
SCATTERED MVFR CONDS WITH CIGS 015-030 AND VSBYS 3-5SM IN -SN BR.
ISOLATED IFR CONDS IN -SN BR WITH CIGS AOB010 AND VSBYS BLO 3SM.
OTHERWISE GENERALLY VFR CONDITIONS WITH CIGS 030-050 AND VSBYS P6SM.
GUSTY SFC WINDS FROM 260-280 DEGREES. WINDS GUSTING UP TO ABOUT
45KTS AT THE HIGHER ELEVATIONS EAST AND SOUTHEAST OF PITTSBURGH AND
UP TO 35KTS ELSW.
