AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
1225 PM EDT TUE JUL 24 2012

.SYNOPSIS...
A SERIES OF UPPER LEVEL DISTURBANCES WILL CROSS THE MID ATLANTIC
REGION THROUGH WEDNESDAY...PRODUCING WIDSPREAD THUNDERSTORMS THIS
AFTERNOON AND EVENING...AND SCATTERED STORMS WEDNESDAY.

&&

.NEAR TERM /THROUGH WEDNESDAY NIGHT/...
AS OF 1030 AM...

ACTIVE SEVERE WEATHER DAY EXPECTED TODAY.

..MORNING UPDATE..LITTLE CHANGE IN THE THINKING ON THE NATURE AND
COVERAGE OF CONVECTIVE ACTIVITY. INITIAL SHOWERS RACING SOUTHEAST
OUT OF WVA AT 35 MPH THIS MORNING WILL INTENSIFY AS THEY REACH THE
AREA AROUND 18Z...MOVING RAPIDLY ACROSS THE AREA IN THE FOLLOWING
4-5 HOUR TIME FRAME. THIS WOULD TAKE THE BULK OF THE THREAT OUT OF
THE AREA A LITTLE EARLIER THIS EVENING THAN THE ONGOING FORECAST.
HOWEVER...AT THIS POINT WILL ONLY BACK UP THE ARRIVAL TIME TO MATCH
THE EXTRAPOLATION ABOVE AND ADD GUSTY WINDS TO THE GRIDDED FORECAST
AS THETA-E DIFF IN THE MID LEVELS WILL EXCEED 35C AND PROGGED DCAPE
EXCEED 1000J/K.

PREVIOUS DISCUSSION...

NORTHWEST FLOW NEAR 20 KNOTS ALOFT OFF THE MOUNTAINS WILL AID
PRODUCTION OF A THICK INVERTED VEE DRY ADIABATIC SURFACE LAYER THIS
AFTERNOON FOR HIGH DOWNDRAFT CAPE POTENTIAL. EXPECT POTENTIAL ENERGY
TO EXCEED 2500 JOULES... AND PERHAPS EXCEED 3500 NEAR AND SOUTHEAST
OF HIGHWAY ONE. PRECIPITABLE WATERS NEAR TWO INCHES. BULK SHEAR UP
FROM MONDAY... TO 24 TO 29 KNOTS... SUSTAINING THUNDERSTORM UPDRAFT
CORES. VORTICITY MAXIMA CURRENTLY IN INDIANA FORECAST TO WEAKEN AS
IT APPROACHES... BUT SET OFF SHOWERS IN WEST VIRGINIA BY LATE
MORNING... AND DRIVE THESE SOUTHEAST INTO NORTHWEST NORTH CAROLINA
BY MID AFTERNOON. SURFACE TROUGH NEAR HIGHWAY ONE THIS AFTERNOON
SHOULD AID CONVECTION NEAR AND EAST OF THE TROUGH.

CURRENT THINKING IS POTENTIAL FOR SEVERE WEATHER HIGHEST ROUGHLY 2
TO 4 PM IN THE NORTHWEST AND 4 TO 8 PM ELSEWHERE AS STORMS SHIFT
SOUTHEAST. PRIMARY THREAT OF DAMAGING DOWNBURST WINDS... THOUGH THE
STRONGER STORMS WILL PRODUCE HAIL LARGER THAN ONE INCH. ADDITIONALLY
SEVERAL STORMS SHOULD BE FREQUENT LIGHTNING PRODUCERS... AND
RESIDENTS SHOULD BE PROMPT IN MOVING INDOORS AHEAD OF STORMS.

FLOOD THREAT OUTSIDE URBAN AREAS LOOKS SMALL GIVEN THE EXPECTED
MOVEMENT OF THESE STORMS.

HAVE TAKEN A TINY TRIM TO FULL SUN HIGH TEMPERATURES IN THE
NORTHWEST DUE TO POTENTIAL FOR THUNDERSTORM OUTFLOWS ARRIVING BEFORE
MAXIMUM HEATING. HOWEVER WITH THICKNESSES FORECAST TO PERHAPS EXCEED
1440 METERS AT GREENSBORO BY 18Z... TEMPERATURES ACROSS CENTRAL
NORTH CAROLINA SHOULD BE WARMER THAN MONDAY. MOSTLY MID 90S TODAY
WITH A VERY FEW UPPER 90S. DEWPOINTS FORECAST TO FALL TO 69 TO 71
THIS AFTERNOON AHEAD OF THUNDERSTORMS. HEAT INDICES BRIEFLY TO
104. NO HEAT ADVISORY.

FORECASTING MOST THUNDERSTORMS TO BE SOUTHEAST OF OUR AREA BY
SUNSET. A SHOWER OR THUNDERSTORM WILL BE A RISK INTO THE EARLY
MORNING HOURS... BUT ISOLATED. THE NORTH CAROLINA TROUGH WILL BE
DRAGGED SOUTHEAST TONIGHT BY ITS PARENT LOW EXITING THE MAINE
COAST TONIGHT. A BACK DOOR FRONT WILL SLIP SOUTH INTO NORTH
CAROLINA AFTER MIDNIGHT... BUT NO MORE THAN AN ISOLATED SHOWER
EXPECTED. WINDS WILL SHIFT TO NORTHWEST TO NORTH OVER PARTS OF THE
NORTH AND THIS WILL ALLOW TEMPERATURES TO APPROACH 70 IN THE
NORTHEAST... WITH MID 70S FORECAST FOR MOST OF THE SOUTH.

LOW LEVEL WINDS WEAKEN A BIT FOR WEDNESDAY AND SHIFT TOWARD THE WEST
BY MID AFTERNOON. NO FAITH IN ANY MODEL FORECAST OF SHORT WAVES IN
THIS NORTHWEST FLOW PATTERN. WILL LEAVE THE CURRENT RAIN CHANCES
INTACT... WITH CHANCES PERHAPS ONE IN FOUR NORTHEAST WHERE MID LEVEL
FLOW FORECAST TO BE DIVERGENT INTO THE AFTERNOON... AND ONE IN THREE
ELSEWHERE.

DOWNDRAFT CAPE FORECAST TO SIGNIFICANTLY LOWER WEDNESDAY THAN TODAY
WITH LOWER MIXING HEIGHTS. A BIT MORE UPPER LEVEL CLOUDINESS WILL
MUTE TEMPERATURES A BIT BUT OTHERWISE THE AIR MASS RELATIVELY
UNCHANGED FROM TUESDAY. WITH QUESTIONABLE SUPPORT ALOFT... THE
NUMBER OF SEVERE THUNDERSTORMS SHOULD DIMINISH FROM TUESDAY.
DAMAGING DOWNBURST WINDS THE PRIMARY THREAT. LIGHTNING POTENTIAL
WILL REDUCED FROM TUESDAY WITH LESS MID LEVEL POTENTIAL ENERGY
AVAILABLE. AN ISOLATED SHOWER OR STORM POSSIBLE IN THE MORNING WITH
MOST CONVECTION AFTER 2 OR 3 PM.

HIGH TEMPERATURES 89 NORTHWEST TO NEAR 95 SOUTHWEST.

UNLESS AIDED BY SUPPORT ALOFT... EXPECT CONVECTION TO END BEFORE
MIDNIGHT. OVERNIGHT LOW TEMPERATURES NEAR 71 NORTHEAST TO NEAR 75
EXTREME SOUTH.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS OF 1225 PM TUESDAY...

MIGRATORY LOW LEVEL RIDGING MOVING EAST ACROSS THE AREA WILL PRODUCE
SOUTHWEST TO WESTERLY FLOW AND INDUCE A HEAT RIDGE REFLECTED IN LOW
LEVEL THICKNESSES IN EXCESS OF 1440M AND H85 TEMPS 22-24C.
CORRESPONDING SURFACE HIGHS EXPECTED TO REACH UPPER 90S...
POTENTIALLY SOME VERY LOW TRIPLE DIGITS. THESE ARE BELOW RECORDS FOR
THE DATES...WITH THE EXCEPTION OF THU AT RDU. SEE CLIMATE SECTION
BELOW. HIGH INSTABILITY WITH NO FORCING MECHANISM WILL FAVOR
CLIMATOGICAL DIURNAL CONVECTION IN THE WESTERN PIEDMONT AND IN THE
COASTAL PLAIN DUE TO DIFFERENTIAL HEATING AND SEA BREEZE
PENETRATION...RESPECTIVELY.

TROF APPROACHING FROM THE WEST AND AN ASSOCIATED SURFACE FRONT WILL
APPROACH FROM THE NW FRIDAY. FRONTAL PASSAGE WILL BE AFTER MAX
HEATING FRIDAY...WITH HIGHS REACHING UPPER 90S...AGAIN WITH
POTENTIALLY A STRAY 100 DEGREE READING. WILL INCREASE THE CHANCE OF
SHOWERS LATER FRIDAY NIGHT DUE TO A LITTLE QUICKER FROPA AS DEPICTED
ON LATEST MODEL RUNS. MILD AND MUGGY WITH LOWS WITHIN A DEGREE OR
TWO OF MIDDLE 70S BOTH NIGHTS.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
AS OF 1225 PM TUESDAY...

MEDIUM RANGE NWP GUIDANCE IS IN GOOD AGREEMENT REGARDING THE GRADUAL
ESTABLISHMENT OF A MEAN TROUGH ALOFT OVER THE EAST COAST THIS
WEEKEND THROUGH EARLY NEXT WEEK. AS THIS TROF BECOMES
ESTABLISHED...THE SURFACE COLD FRONT EARLY THIS WEEKEND WILL PUSH
THROUGH CENTRAL NC ON SAT...WITH RELATIVELY COOLER/DRIER (AND MORE
STABLE) HIGH PRESSURE BUILDING ACROSS THE APPALACHIANS SUNDAY
THROUGH TUESDAY. WITH THE DRIER NORTHWEST FLOW REGIME IN
PLACE...ONLY SLIGHT CHANCE POPS EXPECTED SUNDAY AND MONDAY...WHILE A
POTENTIAL SHORT WAVE DIGGING INTO THE EAST COAST TROF WILL INCREASE
CHANCES ON TUESDAY.

HIGH TEMPERATURES WILL BE NEAR NORMAL...IN THE 90 TO 95 DEGREE RANGE
SATURDAY THROUGH MONDAY...POTENTIALLY A LITTLE COOLER TUESDAY IF WE
GET A REINFORCING SHORT WAVE DEEPENING THE MEAN TROF. PERSISTENCE
LOWS EXPECTED THROUGH THE PERIOD...BASICALLY 70 TO 74.

&&

.AVIATION /18Z TUESDAY THROUGH SATURDAY/...
AS OF 1230 PM...

THE MAIN AVIATION IMPACT THROUGH THE FIRST 6-9 HOURS OF THE TAFS
WILL BE STRONG WINDS AND REDUCED VSBY AND CIGS ASSOCIATED WITH A
LINE OF THUNDERSTORMS EXPECTED TO SWEEP ACROSS THE REGION. OUR
WESTERN PIEDMONT TAF SITES WILL BE AFFECTED BETWEEN 17-20Z...WHILE
OUR EASTERN EASTERN PIEDMONT AND COASTAL PLAIN TAF SITES AFFECTED
BETWEEN 20-24Z. OUTSIDE OF THIS ACTIVITY EXPECTED GENERALLY VFR
CONDITIONS WITH MID/HIGH CLOUDS.

MOSTLY MVFR FOG DEVELOPING LATE TONIGHT AS WINDS SUBSIDE. THEN A
DAILY THREAT FOR ISOLATED TO SCATTERED CONVECTION IN THE
AFTERNOON AND EVENING HOURS WITH ASSOCIATED MVFR CEILINGS AND
VISIBILITY. THERE WILL BE POCKETS OF MVFR TO IFR FOG AND STRATUS
BETWEEN 5 AM AND 9 AM EACH MORNING.
