DISCUSSION
AS OF 320 AM EDT FRIDAY...
KEY MESSAGE 1...SLIGHTLY COOLER BUT WARM TEMPERATURES AND
MINIMAL FIRE WEATHER CONCERNS EXPECTED TODAY.
MORNING WEATHER ANALYSIS SHOWS A WEAK UPPER TROUGH MOVING OVER THE
MID-ATLANTIC REGION. WHILE AT THE SURFACE HIGH PRESSURE CONTINUES TO
REMAIN STEADY OFF THE SE COAST. THE LINE OF SHOWERS TO THE WEST HAVE
BEGUN TO FIZZLE ONCE THEY MOVED OFF THE MOUNTAINS. DECIDED TO LOWER
POPS TO SLIGHT CHANCE DUE TO THE SHOWERS FIZZLING OUT AND HIGH-RES
GUIDANCE CONTINUING TO LIMIT SHOWER ACTIVITY. OTHERWISE,
TEMPERATURES THIS MORNING CONTINUE TO REMAIN QUITE MILD FOR THIS
TIME OF YEAR WITH TEMPS IN THE UPPER 60S TO LOW 70S.
THROUGH THE COURSE OF THE DAY A SHORTWAVE WILL MOVE THROUGH THE AREA
CAUSING AN INCREASE IN CLOUD COVER. DUE TO INCREASE IN HIGH LEVEL
CLOUDS, TEMPERATURES WILL REMAIN SLIGHTLY COOLER THAN PREVIOUS DAYS
WITH HIGHS REACHING IN THE MID TO UPPER 80S ACROSS VA & NC AND LOW
80S ACROSS THE EASTERN SHORE. IN ADDITION, FIRE WEATHER CONCERNS
REMAIN MINIMAL TODAY DUE TO THE LIGHTER WINDS BUT MIN RH VALUES WILL
BE BETWEEN 25-30% INLAND.
KEY MESSAGE 2... FIRE WEATHER CONCERNS ONCE AGAIN INCREASE SATURDAY WITH
UNSEASONABLY WARM TEMPERATURES. A POTENTIALLY MORE SIGNIFICANT FIRE
WX EVENT IS POSSIBLE NEXT MONDAY IN THE WAKE OF THE COLD FRONT BUT
WILL BE DEPENDENT ON RAINFALL SUNDAY.
SATURDAY CONTINUES TO REMAIN ON TRACK WITH WARM/HOT AND DRY
WEATHER CONDITIONS EXPECTED. TEMPERATURES ARE PROGGED TO BE IN THE
UPPER 80S TO LOW 90S INLAND AND MID TO LOW 80S ALONG THE SE COAST
AND MIDDLE TO UPPER 70S ALONG THE COAST. WITH WARMER TEMPERATURES
EXPECTED THIS COULD ALLOW FOR ADDITIONAL MIXING AT THE SURFACE
CAUSING WINDS TO BE HIGHER (15-20MPH GUSTS). THESE GUSTS MIXED WITH
RH VALUES BETWEEN 25-30% COULD LEAD TO AN INCREASE IN FIRE DANGER
ESPECIALLY ALONG AND WEST OF THE I-95 CORRIDOR. WHILE FURTHER EAST
TEMPERATURES ARE EXPECTED TO BE COOLER AND RH HIGHER DUE TO THE
ONSHORE FLOW.
MODEL GUIDANCE FOR SUNDAY CONTINUES TO SHOW A MUCH STRONGER COLD
FRONT CROSSING THE REGION WITH A LOW PRESSURE SYSTEM TRACKING INTO
ONTARIO/QUEBEC. AHEAD OF THE COLD FRONT MOISTURE RETURN LOOKS TO BE
QUITE MINIMAL FOR A WIDESPREAD SOAKING RAINFALL. POPS HAVE INCREASED
JUST SLIGHTLY AND ARE NOW BETWEEN 65-85% FOR MOST OF THE AREA WITH
THE LOWEST TOWARDS THE SW. SHOWERS ARE EXPECTED THROUGH THE DAY,
WITH PERHAPS A LOW END CHANCE OF THUNDER ACROSS THE SE. SHOWERS LOOK
TO FALL PRIMARILY BEHIND THE FRONTAL PASSAGE. WITH THE FRONT PASSING
THE AREA DURING THE DAY, TEMPS IN THE AFTERNOON WILL LIKELY DROP
INTO THE 60S (OR PERHAPS 50S ALL DEPENDING ON IF/WHERE IT RAINS).
THIS COULD EASILY YIELD 24 HOUR TEMP CHANGES ON THE ORDER OF 30
DEGREES F. THE 00Z/17 ENSEMBLE PROBS FOR .1"+ QPF IS REMAINING
STEADY BETWEEN 60-70% , AND ARE HIGHEST ACROSS ACROSS THE NE AND
LOWEST ACROSS THE SW. PROBAILITIES OF ANY GREATER QPF VALUES REMAIN
QUITE MINIMAL (LESS THAN 10%.
BEHIND THE FRONT MONDAY, A MUCH COOLER AND DRIER AIRMASS WILL MOVE
INTO PLACE. THE NBM WHICH OFTEN HAS A BIAS TO HIGH DEW POINTS,
DEPICTS MIN RH VALUES BETWEEN 15-25%. IN ADDITION, IT WILL BE QUITE
BREEZY BEHIND THE FRONT WITH WIND GUSTS BETWEEN 20-25MPH. IF
RAINFALL REMAINS QUITE MINIMAL WITH THE FRONTAL PASSAGE SUNDAY, THE
COMBINATION WITH BREEZY CONDITIONS AND LOW RH COULD GIVE WAY TO RED
FLAG WARNING CRITERIA ESPECIALLY W OF THE I-95 CORRIDOR.
KEY MESSAGE 3...POTENTIAL FOR PATCHY FROST INCREASES MONDAY NIGHT INTO
TUESDAY. THEN TEMPERATURES BEGIN TO INCREASE THROUGH THE MIDDLE
OF THE WEEK.
HIGH PRESSURE AT THE SURFACE IS PROGGED TO MOVE OVER THE AREA
LATE MONDAY INTO TUESDAY. AS THE HIGH MOVES OVERHEAD IT WILL ALLOW
FOR WINDS TO DECOUPLE AND SKIES TO REMAIN CLEAR. THIS WILL ALLOW FOR
STRONG RADIATIONAL COOLING TO OCCUR AND TEMPERATURES COULD DROP INTO
THE LOW TO MIDDLE 30S INLAND AND UPPER 30S TO LOW 40S ALONG THE
COAST. A FREEZE IS NOT EXPECTED AT THIS TIME DUE TO DEW POINTS
REMAINING QUITE LOW. HOWEVER, PATCHY FROST CANNOT BE RULED OUT
ESPECIALLY ACROSS THE FAR NW. BY TUESDAY, THE HIGH WILL MOVE BACK
OFFSHORE ACROSS THE SE AND TEMPERATURES WILL BEGIN TO WARM BACK UP.
THEN THROUGH THE REST OF THE WEEK A RIDGE BUILD BACK INTO PLACE AND
TEMPERATURES WILL ONCE AGAIN RETURN BACK INTO THE 80S WITH DRY
WEATHER PREVAILING.
AVIATION /09Z FRIDAY THROUGH TUESDAY/
AS OF 526 AM EDT FRIDAY...
VFR IS EXPECTED TO PREVAIL THROUGH THE 17/12Z TAF PERIOD.
MOSTLY CLEAR TO PARTLY CLOUDY SKIES THIS MORNING. SOME SHOWERS
HAVE APPEARED ON RADAR AND COULD MOVE OVER THE RIC TERMINAL.
HOWEVER, NO FLIGHT RESTRICTIONS ARE EXPECTED. SKIES GRADUALLY
CLEAR BEHIND THE FEATURE TODAY, WITH PERHAPS SOME CU DEVELOPING
NEAR THE COAST. SW WIND SHIFT TO THE NW TODAY. A LOCALIZED
ONSHORE WIND MAY DEVELOP LATER IN THE AFTERNOON FOR ORF AND ECG
AS A SEA BREEZE ATTEMPTS TO PUSH INLAND.
OUTLOOK: VFR AND DRY CONDITIONS ARE EXPECTED TO PREVAIL THROUGH
SATURDAY NIGHT. MAINLY S-SW WINDS ALSO PREVAIL THROUGHOUT THE
FORECAST PERIOD, AS HIGH PRESSURE SETTLES OVER THE WESTERN
ATLANTIC. SHOWERS ARE LIKELY SUNDAY WITH THE NEXT COLD FRONT,
ALONG WITH BREEZY SSW WINDS AHEAD OF THE FRONT, AND N-NW WINDS
BEHIND THE FRONT LATE SUN INTO MONDAY.
