WHAT HAS CHANGED
12Z TAF AVIATION DISCUSSION UPDATED.
PREVIOUS FROM 341AM SUN...PLACED GEORGETOWN COUNTY WITHIN A
WINTER WEATHER ADVISORY. TEMPS CONTINUE AROUND 30 WITH PCPN
BEING REPORTED IN THE AREA. THE PCPN THAT FALLS WILL EITHER BE
IN THE FORM OF FREEZING RAIN OR FREEZING DRIZZLE AND WILL RESULT
IN ATLEAST A LIGHT GLAZE OR EVEN A FEW ONE HUNDRETHS OF AN INCH
POSSIBLE.
PREVIOUS FROM 250AM SUN... HAVE HELD ONTO THE FREEZING
TEMPERATURES A BIT LONGER THAN THE PREVIOUS UPDATE. THIS BASED
ON THE LATEST SFC OBS TRENDS AND HIGH RES MODEL DATA. HAVE TEMPS
CLIMBING ABOVE 32 BY DAYBREAK AT THE COAST, REACHING ALONG AND
WEST OF THE I-95 CORRIDOR BY EARLY TO MID AFTERNOON. THIS WILL
EXTEND THE FREEZING RAIN POTENTIAL ACROSS THE AREA BUT WITH PCPN
BEING LIGHT AND PATCHY IN NATURE, HAVE BASICALLY KEPT THE SAME
FORECAST ICING ACCUMULATION VALUES, THUS NO CHANGE WITH ANY OF
THE WINTER WEATHER HEADLINES.
KEY MESSAGES
1) FREEZING RAIN AND ASSOCIATED ICE ACCUMULATIONS WILL REMAIN
THE PRIMARY WINTER WEATHER HAZARD ASSOCIATED WITH THIS WINTER
STORM THROUGH THIS MORNING AT THE COAST AND EXTENDING INTO THE
AFTERNOON WELL INLAND. WINTER WEATHER HEADLINES REMAIN
UNCHANGED. THE MILDER TEMPS, ABOVE 32 DEGREES, WILL BE A BIT
SLOWER TO MANIFEST, SPREADING FROM THE COAST AND INLAND TODAY
AND THEN REMAINING ABOVE FREEZING ACROSS THE ENTIRE ILM CWA THRU
TONIGHT. REMOTE POSSIBILITY OF THUNDERSTORMS TONIGHT.
2) EXTENDED PERIOD OF UNSEASONABLY COLD TEMPERATURES
EXPECTED THROUGH NEXT WEEK WITH DANGEROUSLY LOW WIND CHILL
TEMPERATURES AT TIMES, ESPECIALLY MONDAY AND THURSDAY NIGHTS.
DISCUSSION
KEY MESSAGE 1: FREEZING RAIN AND ASSOCIATED ICE ACCUMULATIONS
WILL REMAIN THE PRIMARY WINTER WEATHER HAZARD ASSOCIATED WITH
THIS WINTER STORM THROUGH THIS MORNING AT THE COAST AND
EXTENDING INTO THE AFTERNOON WELL INLAND. WINTER WEATHER
HEADLINES REMAIN UNCHANGED. THE MILDER TEMPS, ABOVE 32 DEGREES,
WILL BE A BIT SLOWER TO MANIFEST, SPREADING FROM THE COAST AND
INLAND TODAY AND THEN REMAINING ABOVE TO WELL ABOVE FREEZING
ACROSS THE ENTIRE ILM CWA THRU TONIGHT. REMOTE POSSIBILITY OF
THUNDERSTORMS TONIGHT.
ONGOING CAD CONTINUES IN FULL TILT. SHALLOW ARCTIC AIRMASS
HOLDING TOUGH ACROSS THE FA, WITH 30-32 DEGREE READINGS
EVEN AT THE COAST. MODELS HAVING DIFFICULT TIME WITH SEVERITY
OF THIS CAD EVENT AS WELL AS THE COLDER TEMPS HAVING HELD ON
LONGER THAN EXPECTED. THIS WILL RESULT IN AN EXTENDED PERIOD OF
FREEZING RAIN AND ICE ACCUMULATION ALL THE WAY TO THE COAST,
WITH COASTAL GEORGETOWN COUNTY THE EXCEPTION, BUT THAT MAY NEED
TO BE RE- VISITED GIVEN LATEST PCPN TRENDS AND THE DENSE SHALLOW
ARCTIC AIR STILL IN PLACE. HIGH RES MODELS STILL WANT TO DECAY
THE ARCTIC AIRMASS FROM TOP/DOWN AND ALSO FROM EAST TO WEST AS
MILD FLOW ALOFT INCREASES ACROSS THE FA. LATEST SAT IMAGERY
DEPICTING THE LOW/MID LEVELS ALSO CONFIRMS THIS TREND. TIMING IS
THE PROBLEM CHILD HERE, WITH REGARD TO THE MILDER TEMPS RAISING
THE THE TEMPS ABOVE 32, AND THUS ENDING THE THREAT FOR FREEZING
RAIN/DRIZZLE. AS MENTIONED PRIOR, HAVE EXTENDED THE OCCURRENCE
OF THE FREEZING PCPN AND THE 32 DEGREE OR LESS READINGS. WILL
CONTINUE TO ADVERTISE THE ICE ACCUMULATION RANGE FROM A TRACE TO
LESS THAN ONE TENTH OF AN INCH AT THE COAST TO ONE TENTH TO TWO
TENTHS FROM THE COAST TO I-95 AND UP TO ONE QUARTER OF AN INCH
ALONG AND WEST OF I-95.
ONCE THE CAD CEASES, TEMPS WILL CLIMB INTO THE 40S INLAND AND
50S AT THE COAST LATER THIS AFTERNOON AND LIKELY CONTINUE THRU
THE NIGHT AHEAD OF THE APPROACHING COLD FRONT. THIS SHOULD GIVE
AMPLE TIME FOR MELTING TO OCCUR ACROSS THE ENTIRE ILM CWA, WITH
OBVIOUSLY THE AREAS ALONG AND WEST OF I-95 TAKING LONGER TO
MELT. THE PCPN EXTENDING AHEAD OF THE APPROACHING COLD FRONT TO
PUSH ACROSS THE FA LATER THIS EVENING AND OVERNIGHT. ELEVATED
INSTABILITY AND DYNAMICS FROM THE PASSAGE OF A 5H S/W TROF
(THAT WAS ONCE A CLOSED 5H LOW IN THE PACIFIC) WILL RESULT IN
THE POSSIBILITY OF AN EMBEDDED TSTORM.
KEY MESSAGE 2: EXTENDED PERIOD OF UNSEASONABLY COLD TEMPERATURES
EXPECTED THROUGH THIS WEEK WITH DANGEROUSLY LOW WIND CHILL
TEMPERATURES AT TIMES, ESPECIALLY MONDAY AND THURSDAY NIGHTS.
TEMPS WILL HOLD IN THE 40S FOR HIGHS MOST DAYS THIS WEEK AS DEEP
MID TO UPPER TROUGH LINGERS ACROSS THE EASTERN CONUS WITH
ARCTIC AIR FLOWING INTO THE CAROLINAS. THE 850 TEMPS DIP TO -10
C MON NIGHT AND THURS NIGHT AND POSSIBLY DOWN TO -15 C NEXT
WEEKEND. THE OVERNIGHT LOWS WILL BE IN SINGLE DIGITS MON NIGHT
AND THURS NIGHT WITH STIFF NORTHERLY WINDS MAKING IT FEEL EVEN
COLDER. SHOULD NOT SEE OVERNIGHT LOWS ABOVE FREEZING UNTIL AT
LEAST A WEEK FROM MON. THESE DANGEROUSLY COLD TEMPS MON NIGHT
AND THURS NIGHT SHOULD LEAD TO A COLD WEATHER ADVISORY.
AVIATION /12Z SUNDAY THROUGH THURSDAY/
IFR CEILINGS TO DOMINATE ACROSS ALL TERMINALS NEARLY THE ENTIRE
12Z FORECAST ISSUANCE PERIOD. AIR MASS HAS FINALLY MOISTENED UP
ENOUGH FOR LOW LEVEL STRATIFORM CLOUDS TO DOMINATE WITH CEILINGS
GENERALLY IN THE 300 TO 700 FT RANGE. CAD HOLDING ON TOUGH AND
AS A RESULT, TEMPS HAVE ONLY STEADIED OVERNIGHT. WITH LIGHT AND
PATCHY PCPN CONTINUING ACROSS THE AREA VIA 88D RETURNS AND HIGH
RES MODEL DATA, HAVE KEPT THE FREEZING RAIN AND DRIZZLE ONGOING
INTO THE MID DAYTIME MORNING HRS FOR THE COASTAL
TERMINALS...AND THRU MID AFTERNOON HRS FOR THE INLAND
TERMINALS. REDUCED VSBY IN FOG HAS BEEN A MAINSTAY AT THE
COASTAL TERMINALS AND SEE NO REASON TO CEASE FROM ADVERTISING
IT THRUOUT MUCH OF THE DAY. HAVE CONTINUED TO ILLUSTRATE A
PROB30 THREAT FOR THUNDER GENERALLY IN THE 22Z THRU 08Z TIME
FRAME AS PCPN AHEAD OF THE COLD FRONT PUSHES ACROSS. AN
EMBEDDED NORTHEAST MOVING 5H S/W TROF WILL PROVIDE DYNAMICS
COMBINED WITH ELEVATED INSTABILITY TO PRODUCE A
TSTORM. NNE WINDS 10 KT WILL DIMINISH TO AROUND NW 5 KT AS THE
CAD BREAKS DOWN ACROSS THE ILM CWA DURING TODAY. SW WINDS
INCREASE TO 10-15 KT G20 KT LATER THIS EVENING AHEAD OF THE
APPROACHING COLD FRONT ALONG WITH MILD TEMPS AS WINTRY PCPN NO
LONGER AN ISSUE.
EXTENDED FORECAST...FLIGHT RESTRICTIONS EXPECTED UP UNTIL
MOISTURE IS SCOURED OUT BEHIND A COLD FRONTAL PASSAGE MON. VFR
SHOULD RETURN BY MON AFTERNOON AND PREVAIL THROUGH THE REMAINDER
OF THE FCST PERIOD. NEXT CFP, ALBEIT DRY, SLATED FOR WED NIGHT
WITH GUSTY NW WINDS AS THE NEXT ARCTIC HIGH SETTLES IN.
MARINE
THROUGH TONIGHT...CAD BREAKING DOWN AND THE SFC PG TO RELAX-
SOME, RESULTING NE WINDS AT INITIALLY 15 TO 25 KT DIMINISHING
TO NEARLY A VARIABLE IN DIRECTION AT 15 KT OR LESS DURING
TODAY AS THE COASTAL TROF GETS PULLED JUST INLAND AND ONSHORE.
TONIGHT, THE COASTAL FRONT ACTUALLY LIFTS NORTH OF THE AREA
WATERS ALTOGETHER WITH S-SW WINDS BECOMING DOMINANT AND
INCREASING TO 15 TO 25 KT WITH A FEW GUSTS UP TO 30 KT. AN
ELONGATED AREA OF SHOWERS WITH POSSIBLE THUNDER, WILL ALIGN
AHEAD OF AN APPROACHING COLD FRONT TONIGHT, PUSHING ACROSS THE
WATERS AND JUST OFFSHORE AROUND DAYBREAK MON. WITH COLD SSTS,
MAY BE DIFFICULT FOR THOSE STRONGER MILD TEMP WINDS ALOFT TO
MIX DOWN TO THE OCEAN SFC. SEAS GENERALLY IN THE 4 TO 8 FT REALM
THIS PERIOD WITH SHORT PERIOD WIND WAVES, RELATIVELY SPEAKING,
DOMINATING GIVEN THE CHANGES IN WIND DIRECTIONS.
MONDAY THROUGH THURSDAY...A SMALL CRAFT ADVISORY WILL BE ONGOING
WITH SEAS RUNNING 5 TO 7 FT THROUGH MON AND WINDS NW AT 20 TO 25
KTS WITH HIGHER GUSTS. HEADING INTO TUES, WINDS AND SEAS WILL
DROP BELOW SCA THRESHOLDS WITH NORTHERLY WINDS DOWN TO 15 TO 20
KTS. WINDS AND SEAS WILL DROP OFF THROUGH TUES AND INTO WED AS
HIGH PRESSURE MIGRATES ACROSS THE SOUTHEAST, BUT WILL INCREASE
ONCE AGAIN AHEAD OF NEXT COLD FRONT WED NIGHT INTO THURS.
