Area forecast discussion, Jun 21, 5:00 PM EDT, 2 hours 10 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
500 PM EDT THU JUN 21 2012
.SYNOPSIS...
UPPER-LEVEL HIGH PRESSURE WILL BUILD OFF THE MID-ATLANTIC COAST
THROUGH FRIDAY BEFORE A COLD FRONT MOVES THROUGH FRIDAY NIGHT. HIGH
PRESSURE AT THE SURFACE WILL BUILD OVERHEAD FOR THE
WEEKEND...PROVIDING MORE SEASONABLE CONDITIONS. ANOTHER COLD FRONT
WILL PASS THROUGH THE AREA MONDAY.
&&
.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
UPPER-LEVEL HIGH PRESSURE WILL CONTINUE TO SHIFT OFF THE
MID-ATLANTIC COAST THROUGH TONIGHT. A PRESSURE TROUGH WILL REMAIN
OVER THE REGION WHILE SURFACE HIGH PRESSURE REMAINS OVER THE
SOUTHEASTERN CONUS.
STRONG SUBSIDENCE FROM THE UPPER-LEVEL HIGH ALONG WITH SUNSHINE HAS
CAUSED HOT CONDITIONS THIS AFTERNOON. LOW-LEVEL MOISTURE HAS ROTATED
AROUND SURFACE HIGH PRESSURE TO OUR SOUTH...CAUSING DEWPOINTS TO BE
IN THE 60S AND LOWER 70S. THE COMBINATION OF THE HEAT ALONG WITH
HIGH DEWPOINTS HAS CAUSED OPPRESSIVE CONDITIONS THAT WILL LAST INTO
THIS EVENING. WILL CONTINUE WITH A HEAT ADVISORY EAST OF THE BLUE
RIDGE MOUNTAINS WHERE HEAT INDICES WILL BE AROUND 105 DEGREES. HOT
AND HUMID CONDITIONS ARE EXPECTED ACROSS LOCATIONS WEST OF THE BLUE
RIDGE MOUNTAINS...BUT AIR TEMPS WILL BE A FEW DEGREES COOLER CAUSING
HEAT INDICES TO TOP OFF IN THE UPPER 90S TO AROUND 100 DEGREES.
THE COMBINATION OF HEAT AND HUMIDITY HAS CAUSED MODERATE AMOUNTS OF
INSTABILITY TO DEVELOP THIS AFTERNOON. LATEST MESOANALYSIS SHOWS
AROUND 1500J/KG OF MLCAPE ACROSS MUCH OF THE AREA. THE CAPPING
INVERSION WILL LIKELY PREVENT T-STORMS FROM DEVELOPING NEAR
WASHINGTON AND BALTIMORE. HOWEVER...WEAK HEIGHT FALLS AND A PRESSURE
TROUGH ALONG WITH TERRAIN CIRCULATION HAS CAUSED THE CAPPING
INVERSION TO ERODE FOR LOCATIONS NEAR AND WEST OF THE BLUE RIDGE
MOUNTAINS INTO CENTRAL VIRGINIA. ISOLATED/SCATTERED THUNDERSTORMS
ARE EXPECTED TO ACROSS THESE AREAS INTO THIS EVENING. LATEST RADAR
ALREADY SHOWS SHOWERS AND T-STORMS DEVELOPING. DESPITE WEAK SHEAR
PROFILES...MODERATE INSTABILITY ALONG WITH MID-LEVEL DRY AIR AND AN
INVERTED V SIGNATURE IN THE FORECAST SOUNDINGS SUGGEST THAT ISOLATED
T-STORMS WILL BE CAPABLE OF BECOMING SEVERE...WITH DAMAGING WINDS
THE PRIMARY THREAT.
WARM AND HUMID CONDITIONS WILL CONTINUE TONIGHT WITH MIN TEMPS
RANGING FROM THE 60S IN THE POTOMAC HIGHLANDS TO THE LOWER AND
MIDDLE 70S IN THE SUBURBS OF WASHINGTON/BALTIMORE...TO NEAR 80 IN
DOWNTOWN WASHINGTON/BALTIMORE. DEWPOINTS IN THE UPPER 60S AND 70S
WILL CAUSE MUGGY CONDITIONS. RESIDUAL BOUNDARIES FROM AFTERNOON AND
EVENING CONVECTION MAY CAUSE ISOLATED T-STORMS TO CONTINUE
OVERNIGHT ACROSS THE AREA. MOST OF THE TIME WILL TURN OUT DRY
THOUGH.
&&
.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
AN UPPER-LEVEL TROUGH WILL BUILD OVERHEAD FRIDAY WHILE A COLD FRONT
APPROACHES FROM THE OHIO VALLEY. A SURFACE TROUGH WILL REMAIN OVER
THE REGION DURING THIS TIME. HOT AND HUMID CONDITIONS ARE EXPECTED
FRIDAY AHEAD OF THE COLD FRONT...WHICH WILL CAUSE MODERATE AMOUNTS
OF INSTABILITY TO DEVELOP. SHOWERS AND T-STORMS ARE LIKELY FRIDAY.
DESPITE WEAK SHEAR PROFILES...THE INSTABILITY ALONG WITH AN INVERTED
V SIGNATURE IN THE SOUNDINGS WILL CAUSE A THREAT FOR SEVERE
THUNDERSTORMS. THE PRIMARY THREAT WILL BE DAMAGING WIND.
CLOUD COVER AND PRECIPITATION WILL ALLOW FOR CONDITIONS TO NOT BE AS
HOT AS TODAY...BUT MAX TEMPS WILL STILL RANGE FROM THE 80S IN THE
MOUNTAINS TO THE MIDDLE 90S ACROSS MOST OTHER LOCATIONS. HEAT
INDICES MAY APPROACH 100 DEGREES...ESPECIALLY EAST OF THE BLUE RIDGE
MOUNTAINS.
&&
.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
COLD FRONT MOVES THROUGH THE CWFA FRIDAY EVENING...WITH
CONVECTION ENDING WEST OF THE BLUE RIDGE BY MIDNIGHT. SOME
SCATTERED ACTIVITY MAY LINGER ALONG AND EAST OF THE INTERSTATE 95
CORRIDOR UNTIL EARLY SATURDAY MORNING.
HIGH PRESSURE BUILDS IN FROM THE WEST LATER ON SATURDAY THROUGH
EARLY SUNDAY. BOTH THE NAM AND GFS BREAK PRECIP OUT AHEAD OF THE
COLD FRONT SUNDAY NIGHT ALONG A LEE TROUGH. CHANCES LOOK TO BE TOO
MINIMAL TO INCLUDE IN THE FORECAST NOW...BUT WILL HAVE TO MONITOR. COLD
FRONT MOVES THROUGH DURING THE DAY ON MONDAY...BRINGING ADDITIONAL
SCATTERED SHOWERS AND THUNDERSTORMS.
UPPER TROUGH SETS UP ALONG THE EASTERN SEABOARD FOR THE REMAINDER
OF THE WEEK...WITH NEAR NORMAL OR SLIGHTLY BELOW NORMAL TEMPS
EXPECTED. A LEE TROUGH MAY SET UP FOR THE MIDDLE PART OF THE
WEEK...BUT PRECIP CHANCE REMAIN TOO LOW TO MENTION AT THIS TIME.
&&
.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
VFR CONDITIONS ARE EXPECTED WITH LIGHT WINDS THROUGH THIS EVENING.
ISOLATED/SCATTERED T-STORMS MAY AFFECT THE WESTERN TERMINALS DURING
THIS TIME. PATCHY BR MAY CAUSE MVFR VSBYS LATE TONIGHT. ISOLATED
CONVECTION CANNOT BE RULED OUT DURING THIS TIME.
VFR CONDITIONS ARE EXPECTED MOST OF FRIDAY...BUT SHOWERS AND
THUNDERSTORMS WILL BE MORE WIDESPREAD. CIGS/VSBYS WILL BE REDUCED IN
ANY CONVECTION THAT DEVELOPS. THUNDERSTORMS WILL ALSO HAVE THE
POTENTIAL TO PRODUCE GUSTY WINDS AND HAIL.
SUB VFR CONDITIONS FRIDAY EVENING...ESPECIALLY IN THE EASTERN
TERMINALS...AS A COLD FRONT MOVES THROUGH THE REGION. SCT SHRA MAY
LINGER ACROSS AREAS EAST OF THE 95 CORRIDOR THROUGH EARLY SATURDAY
MORNING. OTHERWISE...NO REDUCTIONS IN CIGS/VSBYS ANTICIPATED
THROUGH SUNDAY.
A SECOND COLD FRONT MOVES THROUGH ON MONDAY BRINGING ADDITIONAL
SCT STORMS.
&&
.MARINE...
WINDS HAVE TURNED ONSHORE THIS AFTERNOON. WINDS WILL REMAIN LIGHT
THROUGH FRIDAY. AN ISOLATED SHOWER/T-STORM CANNOT BE RULED OUT LATE
TONIGHT...BUT MOST OF THE TIME WILL BE DRY.
MORE WIDESPREAD SHOWERS AND T-STORMS ARE EXPECTED
FRIDAY...ESPECIALLY DURING THE AFTERNOON AND EVENING. T-STORMS WILL
BE CAPABLE OF PRODUCING GUSTY WINDS AND HAIL. LOCALLY HEAVY RAINFALL
WILL ALSO REDUCE VISIBILITY.
NO HEADLINES ANTICIPATED FOR THE LONG TERM PORTION OF THE
FORECAST. WINDS MAY CHANNEL UP THE BAY SUNDAY NIGHT AHEAD OF AN
APPROACHING COLD FRONT...BUT SPEEDS LOOK TO BE JUST BELOW SCA
CRITERIA AT THIS TIME.
