DISCUSSION
KEY MESSAGE #1: RAIN WILL MOVE INTO THE AREA FRIDAY THROUGH THE
WEEKEND
A FRONT WILL SAG INTO THE MID-ATLANTIC MID-WEEK AS MOISTURE
INCREASES OVER THE SOUTHEAST. WITH PRIMARILY ZONAL FLOW ALOFT
THE FRONT WON'T MOVE MUCH THROUGH THE WEEK AS IT GRADUALLY
LIFTS NORTH AS A WARM FRONT. BY WEDNESDAY NIGHT, PWAT VALUES
FROM THE NAEFS RISE TO THE 90TH PERCENTILE OF CLIMATOLOGY AND
REMAIN NEAR OR SLIGHTLY ABOVE NORMAL THROUGH SUNDAY. THIS
SUPPORTS SHOWERS OVER THE REGION FOR LATE WEEK THROUGH MUCH OF
THE WEEKEND. THE MOST SUBSTANTIAL RAINFALL IS EXPECTED SATURDAY
AS A COLD FRONT PUSHES INTO THE SOUTHEAST. A FEW THUNDERSTORMS
ARE POSSIBLE SATURDAY, BUT THE LIMITED AMOUNT OF SURFACE BASED
INSTABILITY KEEPS THE OUTLOOK FOR SEVERE WEATHER LOW AT THIS
TIME.
KEY MESSAGE #2: WELL ABOVE NORMAL TEMPERATURES EXPECTED LATER
THIS WEEK
WITHOUT BELABORING THE POINT, TEMPERATURES WILL BE WELL ABOVE
NORMAL FROM WEDNESDAY THROUGH SATURDAY BUT WILL NOT BE IMPACTFUL.
THURSDAY AND FRIDAY ARE LIKELY TO BE THE WARMEST DAYS WITH
HIGHS IN THE MID TO UPPER 70S AND POSSIBLY BREAKING INTO THE
80S.
AVIATION /00Z WEDNESDAY THROUGH SUNDAY/
VFR EXPECTED THROUGH THE PERIOD.
WINDS DIMINISH WITH SUNSET AS THE NOCTURNAL INVERSION BEGINS.
WINDS ABOVE THE INVERSION WILL REMAIN STRONGER THOUGH, WITH
SPEEDS AROUND FEET FORECAST AROUND 25-30 KNOTS. THIS WILL BE
APPROACHING LLWS CRITERIA, BUT IS EXPECTED TO REMAIN BELOW IT AT
THIS TIME. THE WINDS SHOULD HELP WITH MIXING OVERNIGHT, AND
THUS KEEP ANY FOG AT A MINIMUM. EVEN SO, SOME PATCHY FOG GROUND
FOG COULD DEVELOP AROUND SUNRISE, ESPECIALLY AT AGS AND OGB.
WINDS WILL STRENGTHEN NOTABLY BY LATE WEDNESDAY MORNING, WITH
SOME GUSTS OVER 25 KNOTS LIKELY IN THE AFTERNOON.
EXTENDED AVIATION OUTLOOK...MOISTURE INCREASES THROUGH THE WEEK
LEADING TO INCREASING CHANCES OF MORNING FOG/STRATUS. THE NEXT
CHANCE OF RAIN IS TRENDING TOWARD THE LATE WEEK AND THIS
WEEKEND.
