AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
315 PM EDT MON JUL 25 2011

.SYNOPSIS...
A COLD FRONT WILL MOVE THROUGH THE MID ATLANTIC REGION THIS
EVENING. HIGH PRESSURE WILL BUILD IN BEHIND THE FRONT FOR TUESDAY
AND WEDNESDAY...BRINGING A RETURN OF MORE SEASONABLE CONDITIONS.
HOT AND HUMID CONDITIONS WILL RETURN FOR LATE IN THE WEEK INTO THE
WEEKEND AS HIGH PRESSURE MOVES OFF THE COAST.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
CLUSTERS OF SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE MID
ATLANTIC REGION THROUGH THIS EVENING. ATMOSPHERE IS MOIST AND
UNSTABLE...AND THERE ARE MESOSCALE BOUNDARIES IN PLACE ALONG WITH A
LEE TROUGH AND COLD FRONT TO THE NORTH. COLD FRONT WILL CATCH UP TO
THE LEE TROUGH THIS EVENING...AND ONCE THE COLD FRONT MOVES THROUGH
THIS SHOULD HELP END THE THREAT OF THUNDERSTORMS.

ANY THUNDERSTORMS THROUGH THIS EVENING WILL BE CAPABLE OF PRODUCING
VERY HEAVY RAINFALL WHICH MAY RESULT IN LOCALIZED FLASH FLOODING. IN
ADDITION...WET MICROBURSTS COULD PRODUCE ISOLATED DAMAGING WIND
GUSTS.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
HIGH PRESSURE BUILDS IN BEHIND THE COLD FRONT ON TUESDAY. THIS WILL
ALLOW FOR MOSTLY SUNNY SKIES AND IT WILL FEEL LESS HUMID WITH
DEWPOINTS LOWERING TO AT LEAST THE LOWER 60S BY AFTERNOON.
TEMPERATURES WILL STILL BE WARM AROUND 90 DEGREES FOR HIGH
TEMPERATURES.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
THE COMPACT NATURE OF THE EXITING PARENT UPPER LOW ACROSS NEW
ENGLAND WILL BRING COOLER TEMPS LOCALLY TO THAT AREA. THIS WILL
KNOCK DOWN OUR TEMPS A COUPLE OF DEGREES BUT THE MORE FAVORABLE
CONDITIONS WILL BE OVER NRN NEW ENGLAND MID WEEK. THE PASSAGE OF
THIS UPPER LEVEL SYSTEM HOWEVER WILL DRAG SOME RELATIVELY DRIER AIR
DOWN INTO THE MID ATLC...WHICH WILL MAKE EVEN DAYTIME HIGHS IN THE
90S SEEM MORE BEARABLE THAN IN PREVIOUS DAYS. THEN THE WARM/MOIST
CONDITIONS RETURN STARTING ON THU. AN ELONGATED UPPER RIDGE WILL
STRETCH FROM THE DESERT SW TO THE SRN ATLC COAST. THE RIDGE AXIS
WILL JUMP SLIGHTLY NWD OVER THE TENN VLY AND INTO THE APLCN CHAIN
OVER THE COURSE OF THE DAY. THIS WILL HELP TO AGAIN DRAW A FETCH OF
LOW LEVEL MOISTURE AND WARMER AIR FROM THE SOUTH...WHICH WILL LINGER
THRU THE END OF THE WEEK AND INTO EARLY NEXT WEEK.

A WEAK COLD FRONT AND THE PARENT WEAKENING SHORTWAVE TROUGH WILL
APPROACH FROM THE GREAT LAKES BY THE END OF THE WORK WEEK. THE
SHORTWAVE WILL SPEED OFF TOWARD THE EAST /OVER SERN
CANADA/...LEAVING THE SFC BOUNDARY TO SETTLE OVER THE OHIO VLY
FRI/SAT. THE BOUNDARY WILL SINK DOWN ACROSS THE MID ATLC DURING THE
DAY OF SAT...W/ TYPICAL SUMMERTIME SCATTERED CONVECTION. THE
ASSOCIATED LIFT HOWEVER WILL BE MARGINAL...W/ THE MOST FAVORABLE
ELEMENT FOR CONVECTION BEING THE MOIST LOW LEVEL /AND THE DAYTIME
HEATING/. TEMPS WILL PEAK ON FRI...SINCE THE UPPER RIDGE WILL BE AT
ITS MOST AMPLIFIED JUST TO OUR WEST. HIGHS WILL AGAIN APPROACH THE
U90S W/ HEAT INDICES LIKELY TOPPING OUT IN THE L-M100S DURING THE
AFTN HRS. SAT AFTN WILL BE SIMILAR...POSSIBLY JUST A COUPLE OF
DEGREES LESS OVERALL BOTH IN TEMPS AND DEWPOINTS.

THE TAIL-END OF THE PSEUDO-STATIONARY BOUNDARY WILL BE LAID OUT OVER
THE MID ATLC...LIKELY JUST TO THE SOUTH OF THE CWA. THE PROXIMITY OF
THIS FEATURE WILL KEEP AT LEAST LOW CHANCES FOR DISORGANIZED
CONVECTION ACROSS THE SRN CWA INTO EARLY NEXT WEEK.

&&

.AVIATION /19Z MONDAY THROUGH SATURDAY/...
MEDIUM TO HIGH CONFIDENCE EXISTS IN THUNDERSTORMS AFFECTING THE HUBS
THROUGH ABOUT 20 OR 21Z. CONFIDENCE DECREASES BEYOND THEN HOWEVER
WITH A COLD FRONT DROPPING SOUTH THERE WILL REMAIN A CHANCE OF
THUNDERSTORMS /ACTIVITY CURRENTLY NORTH IN PENNSYLVANIA/ UNTIL
LATER THIS EVENING. COLD FRONT PASSES THROUGH OVERNIGHT. THERE MAY
BE MVFR BR AT IAD/MRB/CHO OVERNIGHT HOWEVER IFR APPEARS UNLIKELY
WITH ENOUGH OF A GRADIENT TO KEEP A NORTHWEST WIND AT 5 TO 10 KT
GOING AND DRIER AIR MOVING IN. VFR CONDITIONS WILL PREVAIL ON
TUESDAY AS HIGH PRESSURE BUILDS IN.

HIGH PRESSURE WILL REMAIN OVER THE REGION THRU THE END OF THE
WEEK...THOUGH A WEAK FRONTAL BOUNDARY WILL ARRIVE BY LATE FRI/EARLY
SAT AND REMAIN SETTLED OVER THE REGION INTO EARLY NEXT WEEK. PRECIP
CHANCES WILL BE LOW UNTIL THAT TIME...WHEN ONLY BRIEF SCATTERED
CONVECTION WILL BE POSSIBLE GIVEN THE PROXIMITY OF THE SFC FRONT.

&&

.MARINE...
SCATTERED THUNDERSTORMS ARE FORECAST TO MOVE ACROSS THE WATERS
THROUGH THIS EVENING...ANY OF WHICH COULD PRODUCE STRONG GUSTY
WINDS. COLD FRONT PASSES THROUGH OVERNIGHT...WITH A NORTHWEST SURGE
THAT MAY COME CLOSE TO SMALL CRAFT ADVISORY CONDITIONS LATE TONIGHT
INTO TUESDAY MORNING. EVENT APPEARS MARGINAL ATTM SO NO SMALL CRAFT
ADVISORY HAS BEEN ISSUED.

HIGH PRESSURE WILL DOMINATE MUCH OF THE WEEK. ONLY BRIEF PERIODS OF
WEAK CHANNELING OVER PORTIONS OF THE BAY OVER THE NEXT SEVERAL DAYS.
LOW PRECIP CHANCES TILL THE COMING WEEKEND.
