AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
936 PM EST FRI FEB 18 2011
.SYNOPSIS...
BEHIND A COLD FRONT...HIGH PRESSURE BUILDS INTO THE AREA THROUGH
THE WEEKEND. A TROUGH OF LOW PRESSURE WILL MOVE ACROSS THE
EASTERN STATES EARLY NEXT WEEK...WITH WELCOME RAIN ON
MONDAY...BEFORE CHANGING TO SNOW MONDAY NIGHT. HIGH PRESSURE THEN
THROUGH MID WEEK BEFORE THE NEXT TROUGH MOVES IN FROM THE WEST
LATE IN THE WEEK.
&&
.NEAR TERM /THROUGH SATURDAY/...
COLD FRONT WAS MOVING ACROSS THE CHESAPEAKE BAY REGION THIS
EVENING...WITH ANY ISOLATED SHOWERS ALONG IT FIZZLING OUT. SKIES
WERE CLEAR BEHIND THE FRONT...AND DEWPOINTS WERE DROPPING
PRECIPITOUSLY. IN ADDITION...WEST WINDS COULD LOCALLY GUST TO 40
OR 45 MPH IN SPOTS THIS EVENING BEFORE RELAXING A BIT FOR A TIME
OVERNIGHT.
MIXING WILL BECOME BETTER LATE AT NIGHT AND INTO SATURDAY MORNING AT
THE SAME TIME THAT 850 MB WINDS ASSOCIATED WITH A LOW LEVEL JET
INCREASE. THIS MEANS THAT WINDS WILL BE BACK ON THE UPSWING TOWARD
DAWN WHEN HIGH WIND WARNINGS AND WIND ADVISORIES GO INTO EFFECT.
WINDS COULD LEAD TO SOME DOWNED TREES AND POWER LINES DURING THE
DAY SATURDAY.
TO BE SURE...SATURDAY WILL BE COOLER THAN TODAY BUT WITH A
DOWNSLOPE FLOW THIS WILL OFFSET THE COLD ADVECTION SOME SO
TEMPERATURES WILL LIKELY BE ABOVE CLIMO.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/...
SATURDAY NIGHT...A STEEP SFC PRESSURE GRADIENT PERSISTS ACROSS THE
MID ATLANTIC AS THE UPPER TROUGH DEEPENS OFF THE ERN SEABOARD. GUSTS
OF STRONG ADVISORY CRITERIA /ABOUT 45 TO 55 MPH/ QUICKLY DROP OFF

MID TO UPPER 20S WITH LOW LEVEL MIXING AND 925 MB TEMPS AROUND -5C.
SUNDAY...LLVL RIDGE FROM A HIGH EAST OF FL MOVES EAST ACROSS THE
CWA...NLY FLOW STILL GUSTING TO AROUND 25 MPH EAST...WITH SWLY FLOW
QUICKLY BUILDING IN FROM THE WEST. LOWER-MID LEVEL MOISTURE
CONVERGENCE ALONG A WARM FRONT EXTENDING ACROSS THE MIDWEST FROM A
DEVELOPING LOW OVER THE CENTRAL GREAT PLAINS WILL BRING A SWATH OF
RAIN INTO THE OHIO VALLEY AND POSSIBLY EAST ALONG THE MASON-DIXON
LINE BY THE LATE AFTERNOON. THE GULF OF MEXICO WILL BE WIDE OPEN IN
THIS PRESSURE PATTERN...PROVIDING AMPLE MOISTURE FOR THE REGION INTO
EARLY NEXT WEEK.
&&
.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...

FORCE THE CENTRAL PLAINS LOW TO SKIRT EAST ACROSS THE MIDWEST AND
NORTHERN MID ATLANTIC. THICK CLOUDS AND OFF AND ON CHANCES FOR RAIN
WILL KEEP MIN TEMPS IN THE UPPER 30S TO NEAR 40F SOUTH. A COLD FRONT
WILL CROSS THE CWA MONDAY AFTERNOON AS THE LOW MOVES SOUTH OF NEW
ENGLAND...SHIFTING THE SLY FLOW TO WLY. HOWEVER...A PERSISTENT
TROUGH AXIS STRETCHING BACK TO THE TN VLY WILL KEEP COLD...CANADIAN
AIR TO THE NW. THEREFORE...DOWNSLOPING FLOW WILL ALLOW TEMPERATURES
TO WARM NICELY...WITH 12Z GFS/ECMWF BOTH PICKING UP MAX TEMPERATURES
INTO THE 60S.
MONDAY NIGHT...THE LOW FROM HUDSON BAY WILL MOVE SOUTH ACROSS NEW
ENGLAND...DRAWING COLD AIR /AROUND -10C H85 TEMPS/ DOWN ACROSS THE
MID ATLANTIC. CONTINUED GULF MOISTURE CONVERGENCE WITH THE TROUGH
AXIS WILL PROVIDE RAIN...ESPECIALLY NORTHWEST MONDAY EVENING. AS THE
BOUNDARY SAGS SOUTH...RAPID COLUMN COOLING SHOULD ALLOW FOR A
CHANGEOVER TO SNOW AROUND MIDNIGHT BEFORE THE BOUNDARY/END OF PRECIP
MOVES SOUTH BY EARLY TUESDAY. WITH GROUND TEMPERATURES WARMING FROM
RECENT ABOVE NORMAL AIR TEMPERATURES...ANY SNOW LATE MONDAY
NIGHT...SHOULD END UP BEING SLUSHY ON THE GROUND. HOWEVER...AMPLE
MOISTURE AND GOOD LIFT SHOULD ALLOW FOR SOME HEAVY PRECIP RATES.
PLEASE PAY ATTENTION TO THIS MONDAY NIGHT SCENARIO OVER THE WEEKEND.
TUESDAY THROUGH THURSDAY...HIGH PRESSURE MOVES SOUTH ACROSS THE
REGION AGAIN. ANY SNOW TUESDAY MORNING SHOULD END RAPIDLY WITH
DOWNSLOPING FLOW. BELOW NORMAL TEMPS TUESDAY...THEN RETURN FLOW
BRING TEMPS BACK TO NORMAL /MID 40S MAX TEMPS/ FOR WEDNESDAY...THEN
ABOVE FOR THURSDAY.
THE UPPER TROUGH MOVES EAST INTO THE ERN CONUS FRIDAY IN A SCENARIO
SIMILAR TO EARLIER IN THE WEEK. CURRENT GUIDANCE SUGGESTS RAIN

THAT SCENARIO AS WELL.
