50 MOST LOCALES.

OVERNIGHT INLAND. ON THE COAST, PARTICULARLY THE OBX, WINDS WILL
GUST UPWARDS OF AROUND 45 MPH, THOUGH REMAIN BELOW WIND ADV
CRITERIA. THE BREEZY CONDITIONS WILL PREVENT A FREEZE OR FROST,

BY DAYBREAK.
SHORT TERM /SATURDAY/

- MULTIPLE FRONTS MID TO LATE NEXT WEEK
HIGH PRESSURE WILL REMAIN DOMINANT UNTIL TUESDAY WHEN THE NEXT
WAVE IS FORECAST TO TRAVERSE THE EASTERN U.S.
SATURDAY NIGHT...A LACK OF CLOUD COVER AND LIGHT WINDS WILL
ALLOW FOR EFFICIENT RADIATIVE COOLING, SO LOWS WILL BE BACK DOWN
TO THE MID 30S ACROSS THE COASTAL PLAIN (MID 40S BEACHES).
SUNDAY - TUESDAY...ZONAL FLOW ALOFT AND BUILDING HIGH PRESSURE
AT THE SURFACE WILL SUPPORT A DRY AND GRADUALLY WARMER FORECAST
FOR THE END OF THE WEEKEND AND START OF NEXT WEEK. HIGHS WILL
INCREASE FROM THE LOW TO MID 60S ON SUNDAY TO UPPER 60S TO LOW
70S ON TUESDAY. A FRONT IS FORECAST TO CROSS ENC ON TUESDAY
AFTERNOON, BUT GUIDANCE IS NOT IN AGREEMENT ON HOW WET OR DRY
THIS SYSTEM WILL BE, SO I OPTED TO LEAN TOWARDS THE DRIER
GUIDANCE AT THIS TIME AND CAPPED POPS AT 20%.
WEDNESDAY - THURSDAY...WEDNESDAY LOOKS MOSTLY DRY AS OF NOW AS
HIGH PRESSURE WILL BRIEFLY RESUME. BY WEDNESDAY EVENING,
HOWEVER, A STATIONARY BOUNDARY WILL SETUP ACROSS ENC AND LINGER
