.SYNOPSIS...

AN UNSEASONABLY STRONG UPPER TROUGH WILL FINALLY LIFT OUT OT THE
EAST OF THE REGION BY FRIDAY. HIGH PRESSURE WILL THEN BUILD IN AND
SLOWLY DRIFT OFF THE EAST COAST OVER THE WEEKEND. MUCH WARMER
TEMPERATURES WILL MOVE INTO REGION FOR THE WEEKEND...AND VERY WARM
AND INCREASINGLY HUMID WEATHER WILL CONTINUE INTO THE MIDDLE OF
NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...

VIZ LOOPS SHOW THE LARGE SHIELD OF STRATOCU FROM THE OHIO VALLEY
UP INTO EASTERN CANADA. OTHER THAN A STRAY LIGHT SHOWER OR
SPRINKLE OVER NORTHERN AREAS...WE WILL REMAIN DRY UNDER THE
M-CLOUDY SKIES THROUGH LATE DAY.

TODAY WILL BE THE LAST COOL DAY FOR QUITE A WHILE. BELOW SEASONAL
ENS MEAN 8H TEMPS OF ONLY AROUND 10C SHOULD TRANSLATE TO MAX TEMPS
FROM THE U60S OVER THE ALLEGHENIES...TO THE MID-UPPER 70S ACROSS
THE LOWER SUSQ VALLEY.

SKIES SHOULD SCATTER OUT QUICKLY WITH LOSS OF HEATING...LEADING TO
A COOL NIGHT WITH PRIME RADIATIONAL COOLING CONDITIONS. WITH
DEWPOINTS GENERALLY IN THE LOW TO MID 50S...WE SHOULD EASILY COOL
CLOSE TO THESE READINGS LEADING TO AREAS OF LATE NIGHT FOG AND LOW
CLOUDS.

&&

.SHORT TERM /FRIDAY/...

FRIDAY WILL BEGIN OUR WARM UP AS HEIGHTS ALOFT BEGIN TO BUILD.
AFTER SOME EARLY MORNING FOG...SKIES WILL BECOME PARTLY TO MOSTLY
SUNNY AND HIGHS WILL AVERAGE SOME 5-8 DEG WARMER THAN TODAY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
SFC HIGH SLIDES EAST AND OFF THE MID ATLANTIC COAST OVER THE
WEEKEND. DEVELOPING SWRLY SFC FLOW...TOPPED BY A GENERALLY
ZONAL/WESTERLY FLOW ALOFT WILL LEAD TO A STEADY WARMUP SATURDAY
AND SUNDAY.

A WEAK TROUGH AT THE SFC AND ALOFT WILL APPROACH FROM THE OHIO
VALLEY...BUT SHOULD WEAKEN AS IT ENCOUNTERS RISING HEIGHTS EAST OF
THE APPALACHIANS.

A FEW SCATTERED SHOWERS ARE POSSIBLE THIS WEEKEND...MAINLY ACRS
THE NORTHERN AND WESTERN MOUNTAINS.

THE WEATHER LOOKS GREAT INTO NEXT WEEK...AS IT REMAINS ON THE DRY
SIDE...AND TEMPERATURES WARM BACK UP TO NORMAL OR A LITTLE ABOVE
NORMAL.

WILL HAVE TO KEEP AN EYE ON THE S.E. US...AS WE GET INTO NEXT
WEEK WITH PROBABLE HURRICANE ERIKA LURKING SOMEWHERE JUST OFF THE
FL/GA COAST...AND MVG GRADUALLY NORTH OR NW.

IF THE UPPER LEVEL RIDGE BUILDS ACROSS THE NE EARLY NEXT
WEEK...AS INDICATED...THEN THIS WOULD KEEP ANY STORMY
WEATHER TO THE SOUTH AND WEST OF CENTRAL PA.

WIDESPREAD CEILINGS IN THE 4000-6000` RANGE WILL SCATTER OUT THIS
EVENING WITH THE LOSS OF HEATING. THE CLEAR SKIES AND LIGHT WINDS
