NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC  
930 PM EST FRI FEB 22 2019  
   
SYNOPSIS
 
 
A FRONT WILL REMAIN STALLED TO THE SOUTH OF THE REGION OVERNIGHT.  
THE FRONT IS EXPECTED TO THEN LIFT BACK TO THE NORTH AS A WARM  
FRONT SATURDAY AND SATURDAY NIGHT, RESULTING IN A CONTINUED  
UNSETTLED WEATHER PATTERN. A STRONG COLD FRONT WILL CROSS THE  
REGION SUNDAY. HIGH PRESSURE WILL BUILD IN FROM THE NORTHWEST  
EARLY NEXT WEEK.  
 

 
   
NEAR TERM /OVERNIGHT/
 
 
AS OF 930 PM FRIDAY...LATEST SFC ANALYSIS SHOWS STATIONARY  
FRONT STALLED WELL SOUTH OF THE AREA THIS EVENING WITH HIGH  
PRESSURE BUILDING IN FROM THE NORTH, SETTING UP ANOTHER CAD  
SITUATION ACROSS ENC. NO SIGNIFICANT CHANGES NEEDED TO PREVIOUS  
FORECAST FOR UPDATE. OVERRUNNING LIGHT RAIN AND DRIZZLE  
CONTINUES ACROSS ENC, WITH BULK OF RAIN ACROSS THE NORTHERN  
TIER. THE BEST RAIN CHANCES WILL REMAIN ACROSS THE NORTHERN HALF  
OF THE FORECAST AREA OVERNIGHT, BUT LIGHT RAIN AND DRIZZLE  
EXPECTED EVERYWHERE. WITH A COOL NORTHEAST FLOW, TEMPS WILL HOLD  
STEADY UNDER THICK CLOUD COVER, GENERALLY IN THE 40S.  
 

 
   
SHORT TERM /SATURDAY/
 
 
AS OF 310 PM FRIDAY...THE FRONT MENTIONED ABOVE WILL SLOWLY  
LIFT BACK TO THE WARM FRONT DURING THE DAY SATURDAY. THIS WILL  
SHIFT THE AXIS OF PRECIPITATION NORTHWARD THROUGH THE DAY, WITH  
THE SOUTHERN HALF OF THE AREA DRYING OUT BY AFTERNOON. THE  
COLDER AIR WILL HANG IN TOUGH, ESPECIALLY INLAND AND AREAS TO  
THE NORTH WHERE HIGHS HOLD IN THE 40S. FARTHER SOUTH AND  
ESPECIALLY TOWARD THE CRYSTAL COAST, HIGHS WILL APPROACH 60 BY  
AFTERNOON DESPITE A FAIR AMOUNT OF CLOUDS HOLDING ON.  
 

 
   
LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/
 
 
AS OF 315 PM FRI...STEADY WARMING OVERNIGHT SATURDAY GIVES WAY TO A  
COLD FRONT CROSSING THE REGION SUNDAY AFTERNOON USHERING DRY HIGH  
PRESSURE FOR THE FIRST HALF OF THE WEEK. ANOTHER ROUND OF UNSETTLED  
WEATHER IS POSSIBLE AT THE END OF THE PERIOD ALTHOUGH CONFIDENCE IS  
LOW.  
 
SAT NIGHT THROUGH SUNDAY...WARM FRONT LIFTS TO THE N SAT NIGHT  
DIMINISHING PRECIP CHANCES, AND KEPT SLIGHT CHC ACROSS THE REGION. A  
NON DIURNAL TEMPERATURE CURVE IS LIKELY SATURDAY NIGHT AS THE REGION  
COMES UNDER THE INFLUENCE OF WAA AHEAD OF A DEEP SURFACE LOW LIFTING  
INTO THE GREAT LAKES AND ASSOCIATED COLD FRONT TO THE WEST. MDLS  
CONTINUE TO SHOW LIMITED MOISTURE AND VERY LITTLE QPF ALONG AND  
AHEAD OF COLD FRONT SUNDAY, SO CONTINUED LOW CHC POPS EARLY  
DIMINISHING AND ENDING LATE. VERY WARM SUNDAY WITH INLAND AREAS WELL  
INTO THE 70S WITH 65 TO 70 BEACHES. IT WILL BECOME WINDY SUNDAY WITH  
SW WINDS OF 15-25 MPH, WITH SOME GUSTS UP TO 30-35 MPH.  
 
SUNDAY NIGHT THROUGH TUE...DRY HIGH PRES BUILDS IN THRU TUE WITH  
TEMPS NOT FAR FROM NORMAL WITH HIGHS LOWER 50S NE TO AROUND 60/LOWER  
60S SW MON AND TUE. NW WINDS MONDAY WILL REMAIN AROUND 10-15 MPH  
WITH A FEW HIGHER GUSTS UP TO 20-25 MPH; OTHERWISE WINDS THROUGHOUT  
THE PERIOD WILL BE FAIRLY LIGHT.  
 
WED AND THU...MODELS CONTINUE TO DIFFER THIS PERIOD AS NEXT FRONTAL  
SYSTEM IMPACTS THE AREA. THE GFS IS THE WETTER SOLUTION, GENERATING  
MULTIPLE SOUTHERN STREAM SHORTWAVE TROUGHS OVER THE SOUTHERN PLAINS  
AND DRAGGING A COUPLE SYSTEMS OVER THE AREA DURING THE SECOND HALF  
OF THE WEEK. THE ECMWF IS MUCH DRIER, KEEPING MORE UNSETTLED WEATHER  
PINNED ALONG THE GULF COAST WITH HIGH PRESSURE REMAINING IN CONTROL.  
STILL PLENTY OF UNCERTAINTY THIS PERIOD AND KEPT POPS IN SLIGHT CHC  
TO LOW CHC RANGE FOR NOW. HIGHS WILL BE IN THE LOW/MID 50S NE TO  
LOWER 60S SW.  
 

 
   
AVIATION /02Z SATURDAY THROUGH WEDNESDAY/
 
 
SHORT TERM /THROUGH SATURDAY/...  
AS OF 930 PM FRIDAY...CHALLENGING FORECAST THROUGH THE  
OVERNIGHT PERIOD, BUT EXPECT PRED WIDESPREAD SUB-VFR  
CONDITIONS(IFR OR LOW END MVFR CONDITIONS). MIX OF IFR AND MVFR  
ACROSS THE TERMINALS RIGHT NOW WITH AREAS OF LIGHT RAIN AND  
DRIZZLE. GIVEN THE PATTERN IT WOULD MAKE SENSE THAT IFR CEILINGS  
WOULD REMAIN LOCKED IN THROUGH THE PERIOD, BUT MOST GUIDANCE  
SHOWS CEILINGS IMPROVING FOR A FEW HOURS THIS EVENING THEN  
LOWERING AGAIN LATE TONIGHT AND EARLY SAT MORNING. CEILINGS WILL  
CONTINUE TO LOWER SATURDAY, LIKELY BECOMING LIFR DURING THE DAY  
WITH AREAS OF LIGHT RAIN/DRIZZLE. AREAS OF FOG MAY DEVELOP LATE  
SAT AFTERNOON INTO SAT NIGHT.  
 
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...  
AS OF 645 PM FRI...LIMITED SHOWER COVERAGE SATURDAY NIGHT WILL  
SOME BOUTS OF SUB-VFR CONDITIONS STILL LIKELY. AREAS OF FOG WILL  
BE POSSIBLE SATURDAY NIGHT INTO SUNDAY MORNING. LLWS COULD  
DEVELOP SUNDAY MORNING AS SW JET STRENGTHENS. LITTLE SHOWER  
COVERAGE EXPECTED SUNDAY ASSOCIATED WITH PASSING COLD FRONT ON  
SUNDAY WITH REGION FIRMLY IN THE WARM SECTOR, SO MAINLY VFR  
EXPECTED. GUSTY SW WINDS EXPECTED SUNDAY WITH GUSTS UP TO 30  
KNOTS POSSIBLE. HIGH CONFIDENCE IN VFR DOMINATING THROUGH  
TUESDAY. LESS CERTAINTY ON WEDNESDAY DUE TO MODEL DIFFERENCES  
WITH A POTENTIAL ROUND OF UNSETTLED WEATHER BUT STILL EXPECT  
PREDOMINANTLY VFR.

SOUND. UP NORTH WE REMAIN JUST BELOW SMALL CRAFT CRITERIA. AS
