KEY MESSAGE 1...INCREASED FIRE DANGER FOR TODAY.
EARLY MORNING ANALYSIS SHOWS AN UPPER TROUGH SITUATED OVER THE
EASTERN UNITED STATES. WHILE AT THE SURFACE, THE SECONDARY COLD
FRONT IS SITUATED ALONG THE SPINE OF THE APPALACHIAN MOUNTAINS WITH
THE SURFACE HIGH FURTHER WEST OVER THE UPPER MIDWEST. AHEAD OF THE
FRONT TEMPERATURES ARE IN THE LOW TO MIDDLE 40S WITH SOME UPPER 30S
ACROSS THE FAR NW PIEDMONT AND EASTERN SHORE. SOME PATCHY GROUND FOG
IS POSSIBLE THIS MORNING ESPECIALLY ACROSS SE VA AND NE NC WHERE
SOME POCKETS OF HIGHER DEW POINTS REMAIN.
THROUGH BY THE MID TO LATE MORNING THE SECONDARY COLD FRONT WILL
PUSH THROUGH THE AREA HELPING TO INCREASE WINDS AND USHER IN ADDITIONAL
DRIER AIR. WINDS WILL INCREASE OUT OF THE NW WITH GUSTS UPWARDS OF
20-25MPH. WILL NOTE, SOME 30MPH GUSTS CANNOT BE RULED ESPECIALLY
ACROSS THE EASTERN SHORE. WITH THE DRIER AIR COMING INTO PLACE DEW
POINTS WILL LOWER THROUGH THE DAY WITH RH VALUES CRASHING BETWEEN 20-
25% AND PERHAPS SOME TEENS ACROSS THE PIEDMONT. WITH THE VERY
LIMITED RAIN THAT FELL SUNDAY AN SPS FOR INCREASED FIRE DANGER HAS
BEEN ISSUED FOR VA AND NC. WILL COLLABORATE WITH MD FOREST SERVICE
IN THE MORNING TO SEE IF AN SPS FOR INCREASED FIRE DANGER IS NEEDED.
IN ADDITION, THERE HAS BEEN HINTS OF POSSIBLE SHOWERS ACROSS MD IN
THE AFTERNOON ASSOCIATED WITH THE FRONT. HOWEVER, LATEST SOUNDING
PROFILES SHOW A VERY DRY LOW LEVEL. THIS WOULD ALLOW FOR THE RAIN TO
EVAPORATE BEFORE REACHING THE SURFACE CAUSING VIRGA.
KEY MESSAGE 2...COLD TEMPERATURES TONIGHT WITH TEMPERATURES FALLING INTO THE
LOW TO MID 30S INLAND. FROST AND/OR FREEZE CONDITIONS ARE
EXPECTED TONIGHT INTO TUESDAY MORNING, WITH THE BEST CHANCES
FOR FREEZING TEMPERATURES ROUGHLY ALONG/WEST OF I-95 AND OVER TO
THE MD EASTERN SHORE.
A SURFACE HIGH PRESSURE BUILDS IN ACROSS THE AREA TONIGHT, ALLOWING
FOR MUCH STRONGER RADIATIONAL COOLING TO OCCUR COMPARED TO THE
PREVIOUS NIGHT. TEMPERATURES ARE PROGGED TO FALL INTO THE LOW TO MID
30S FOR MUCH OF THE INLAND AREAS AND PERHAPS SOME UPPER 20S ACROSS
THE NW PIEDMONT. THERE IS THE POSSIBILITY OF LOW TO MID 20S ACROSS
THE NW PIEDMONT AS MOS GUIDANCE HAS NOTED. IT IS NOT OUT OF THE
POSSIBILITY GIVEN THE EXTREMELY DRY AND COLD AIRMASS IN PLACE AND IF
THE HIGH IS OVER AHEAD AND DECOUPLING OCCURS. WITH HIGH ENOUGH
CONFIDENCE IN THESE COLD TEMPERATURES THE FREEZE WATCH HAS BEEN
UPGRADED TO A FREEZE WARNING WEST OF I-95 AND OVER TO THE MD EASTERN
SHORE WHERE THERE IS THE BEST POTENTIAL TO SEE SUB-FREEZING
TEMPERATURES. WHILE FURTHER EAST, TEMPERATURES ARE PROGGED TO BE
BETWEEN 32-36F AND FROST FORMATION IS POSSIBLE. THEREFORE, FROST
ADVISORIES HAVE BEEN ISSUED ACROSS PORTIONS OF EASTERN AND SE VA AND
NE NC.
KEY MESSAGE 3...A WARMING TREND IS EXPECTED THROUGH MID TO LATE WEEK. RAIN
CHANCES CONTINUE TO REMAIN LOW UNTIL PERHAPS THE WEEKEND.
THE SURFACE HIGH WILL EVENTUALLY SLIDE OFF THE SE COAST TUESDAY
ALLOWING FOR TEMPERATURES TO MODERATE (THOUGH STILL REMAINING BELOW
AVERAGE, ESPECIALLY ON THE COAST AND THE EASTERN SHORE). THEN
THROUGH THE MIDDLE TO LATE WEEK TEMPERATURES RETURN BACK INTO THE
HIGH 70S AND 80S. RAIN CHANCES CONTINUE TO LOOK MINIMAL THROUGH MUCH
OF THE WEEK. THE NEXT CHANCE OF RAIN IS WEDNESDAY AS A COLD FRONT
MOVES THROUGH THE AREA. A STRAY SHOWER CANNOT BE RULED OUT. WILL
ALSO MENTION THAT A POSSIBLE RUMBLE OF THUNDER CANNOT BE RULED OUT AS
SHORT RANGE MODELS HINT ON SOME MUCAPE AHEAD OF THE FRONT. NEITHER
THE 00Z EPS OR GEFS CONTINUE TO REMAIN NOT IMPRESSED WITH THIS
SYSTEM, CONTINUING TO AVERAGING ~0.10" OF QPF (AT MOST).BY THIS
WEEKEND MODELS ARE CONTINUING TO HINT ON A MUCH STRONGER SYSTEM,
BRINGING ANOTHER CHANCE FOR RAINFALL. AS OF THIS FORECAST UPDATE IT
DOES NOT LOOK TO BE A DROUGHT BUSTER BUT IT COULD STILL POTENTIALLY
BRING ADDITIONAL BENEFICIAL RAINFALL TO THE AREA.
AVIATION /09Z MONDAY THROUGH FRIDAY/
AS OF 508 AM EDT MONDAY...
PREDOMINATE VFR/DRY CONDITIONS EXPECTED AT MOST SITES THROUGH
TODAY. SOME PATCHY GROUND FOG HAS FORMED ACROSS PHF AND ECG AND
IS CAUSING THE SENSOR TO READ A VARIETY OF FLIGHT RESTRICTIONS.
HOWEVER, AS WINDS HAVE STARTED TO INCREASE THE PATCHY GROUND FOG
HAS BEGUN TO MOVE AWAY FROM THE SENSOR AND HAS RETURNED TO
PRIMARILY VFR STATUS. OTHERWISE WINDS BECOME GUSTY BY LATE
MORNING INTO THE AFTERNOON, IN THE WAKE OF A SECONDARY COLD
FRONT DROPPING SOUTH ACROSS THE AREA. THEN BY TONIGHT, HIGH
PRESSURE SETTLES OVER THE AREA ALLOWING WINDS TO BECOME LIGHT
AND VARIABLE UNDER CLEAR SKIES.
OUTLOOK: CONDITIONS REMAIN VFR THROUGH TUESDAY NIGHT. ANOTHER
WEAK FRONT MAY DROP SOUTH ACROSS THE AREA WEDNESDAY, BRINGING
AT LEAST A LOW-END CHANCE FOR RAIN SHOWERS AND INCREASING CLOUD
COVER. VFR CONDITIONS THURSDAY INTO FRIDAY.
