OVER THE WEEKEND.

&&

.NEAR TERM /THROUGH SATURDAY/...
RECORD LOW MAX TEMP WAS SET AT ECG TODAY...BOTH ORF AND SBY TIED
THEIR RECORD LOW MAX TMPS. SEE RERECG/RERORF/RERSBY FOR DETAILS.

PVS DSCN:
THE CURRENT SURFACE ANALYSIS SHOWS A LARGE SPRAWLING AREA OF
ARCTIC HIGH PRESSURE CENTERED FROM THE ARKLATEX INTO THE INTERIOR
NORTHEAST, WITH A SFC RIDGE EXTENDING E-NE ACROSS THE SOUTHEAST
INTO THE MID-ATLANTIC. ARCTIC HIGH PRESSURE SETS UP ALONG THE
COAST OVERNIGHT, ALLOWING FOR CLEAR AND UNSEASONABLY COLD
CONDITIONS. MANY LOCATIONS WILL EXPERIENCE LOWS IN THE LOW/MID
TEENS...WHICH AGAIN ARE NEARLY -2 ST DEV FROM THE SEASONAL MEAN.

INCREASING ZONAL FLOW THIS WEEKEND WILL PUSH THE ARCTIC HIGH WELL
OFFSHORE. ADDITIONALLY ANY NRN STREAM SYSTEMS WILL STAY WELL N OF
THE MID ATLANTIC. SW LOW-LEVEL FLOW WILL RESULT IN A SUBSTANTIAL
MODERATING TREND...WITH TEMPERATURES RETURNING TO SEASONAL NORMALS
INTO EARLY NEXT WEEK. HIGHS SATURDAY RANGE FROM THE MID 40S TO
LOW 50S OVER INTERIOR VA AND NE NC...WITH LOW/MID 40S OVER THE ERN
SHORE AND COASTAL SE VA/NE NC. LOWS SATURDAY MORNING SHOULD BE
MILDER AND RANGE FROM THE UPPER 20S TO MID 30S. SKY COVER SHOULD
GENERALLY REMAIN MOSTLY CLEAR/SUNNY SAT...WITH OCCASIONAL HIGH
CLOUDS STREAMING ACROSS THE NORTHERN MID-ATLANTIC.

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
LATTER HALF OF THE WEEKEND INTO EARLY NEXT WEEK CHARACTERIZED BY
A GRADUAL WARMUP IN TEMPS SUN-MON, THOUGH TEMPS STILL REMAIN
SLIGHTLY BELOW NORMAL FOR THE PERIOD. SPLIT FLOW SETUP CONTINUES
SUNDAY AND MONDAY...W/NORTHERN STREAM SHORTWAVE ENERGY REMAINS
WELL NORTH OF THE MID ATLANTIC TOWARDS THE GREAT LAKES AS SOUTHERN
STREAM SHORTWAVE ENERGY CONFINED TO THE 4 CORNERS/SOUTHERN HIGH
PLAINS REGION INTO NW MEXICO. DO HAVE INCREASING RAIN CHANCES BY
SUNDAY NIGHT, MAINLY ACROSS THE SOUTHERN THIRD OF THE AREA, AS THE
SOUTHWEST TROUGH WILL EJECT SOME WEAK SHORTWAVE ENERGY THAT WILL
SCOOT ACROSS THE PLAINS AND MID-SOUTH SUNDAY AND SUNDAY NIGHT. AS
THIS ENERGY PROGRERSSES EAST, IT`LL SPREAD SOME LIGHT RAIN/SCT
SHRAS ACROSS SOUTHERN SECTIONS SUNDAY NIGHT/MONDAY MORNING. DO TO
LOW CHCS FOR MEASURING, WL STICK WITH NO HIGHER THAN A 20% POP
MAINLY ALONG AND SOUTH OF THE VA/NC BORDER. REMAINING CLOUDY
THROUGH MONDAY, WITH POPS INCREASING BY LATE AFTERNOON AND NIGHT
AHEAD OF MORE SUBSTANTIAL PIECE OF SOUTHERN STREAM SHORTWAVE
ENERGY, WHICH SHOULD BRING MORE WIDESPREAD PRECIPTATION FROM SW TO
NE TO THE AREA MONDAY NIGHT.

FOR TEMPS, THICKNESS TOOLS INDICATING AFOREMENTIONED WARMUP FROM THE
WEEKEND INTO NEXT WEEK. WENT TOWARDS THE HIGHER END OF GUIDANCE ON
SUNDAY WITH SFC HIGH IN PLACE ACROSS THE CAROLINAS. HIGHS IN THE MID
50S NORTH TO NEAR 60 SOUTH (EXCEPTION BEING UPPER 40S TO NEAR 50
ALONG ATLANTIC COAST OF EASTERN SHORE). GIVEN CONSIDERABLE
CLOUDINESS, WENT TOWARD THE LOWER END OF THE GUIDANCE ENVELOPE ON
MONDAY WITH PLENTY OF CLOUDS. TEMPERATURES GENERALLY SIMILAR TO
THOSE OF SUNDAY...U50S TO NEAR 60 SOUTH...LOW TO MID 50S NORTH.

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
SFC HIGH PRESSURE SLIDES EAST AND OFF THE MID-ATLANTIC COAST MONDAY
NIGHT INTO TUESDAY. MEANWHILE...LOW PRESSURE WILL BE MOVING
NORTHWARD FROM THE GOMEX ALONG A STALLED FRONTAL
BOUNDARY...EVENTUALLY PUSHING OFF THE MID-ATLANTIC COAST LATER
TUESDAY. AS A RESULT...SOME DEEPER LOW LEVEL MOISTURE WILL LIFT NWRD
INTO THE REGION...BRING A GOOD CHANCE OF RAIN ON TUESDAY..ESPECIALLY
SOUTHERN AREAS. THE STALLED BOUNDARY REMAINS OVER THE SE WEDNESDAY
FOR LOW CHANCE POPS ACROSS THE SOUTHERN HALF OF THE FA. HIGH
PRESSURE OVER THE GREAT LAKES WILL EXPAND SOUTHWARD BY THURSDAY FOR
DRY WX. THERE IS THE POTENTIAL FOR ANOTHER GOMEX SYSTEM TO BRING
RAIN BACK TO THE AREA NEXT FRIDAY. MIN TEMPS WILL RANGE FROM THE MID
30S TO LWR 40S...AND MAX TEMPS WILL RANGE FROM THE MID 40S TO MID 50S
ON TUE...TO THE LOW/MID 50S TO LWR 60S WED AND THU. COOLING BACK
