.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/...
SECOND UPDATE...
RED FLAG WARNING NOW IN EFFECT FOR THE OVERNIGHT HRS...W/ MANY
AREAS ALREADY MEETING CRITERIA AND WILL CONTINUE TO WELL INTO THE
DAYTIME HRS TODAY.
PREV UPDATE...A WIND ADVISORY IS NOW IN EFFECT FOR THE NRN HALF OF
THE CWA UNTIL THE HIGH WIND WARNING TAKES EFFECT /5 AM/. MID 30KT
GUSTS ALREADY APPEARING ACROSS THE POTOMAC RVR VLY SITES AND WILL
LIKELY CONTINUE INTO THE OVERNIGHT HRS.
FROM PREV DISC...
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/...

MID ATLANTIC AS THE UPPER TROUGH DEEPENS OFF THE ERN SEABOARD. GUSTS

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.

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

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
