NWS STORM PREDICTION CENTER NORMAN OK
0534 PM CST FRI JAN 10 2025
AREAS AFFECTED...PORTIONS OF CENTRAL AND NORTHERN SOUTH CAROLINA
INTO CENTRAL NORTH CAROLINA
CONCERNING...FREEZING RAIN
VALID 102334Z - 110330Z
SUMMARY...HEAVIER FREEZING RAIN RATES WILL CONTINUE TO SPREAD INTO
NORTHERN SOUTH CAROLINA INTO CENTRAL NORTH CAROLINA THROUGH THE
EVENING HOURS. .06 INCH/3 HOUR RATES ARE EXPECTED.
DISCUSSION...LOW-LEVEL WARM-AIR ADVECTION CONTINUES TO INTENSIFY
ACROSS GA INTO SC AHEAD OF AN APPROACHING MID-LEVEL TROUGH. WHILE A
WINTRY MIX IS ONGOING ACROSS CENTRAL PORTIONS OF NC INTO SC, THE
CONTINUED WAA IN THE 850-700 MB LAYER WILL ENCOURAGE FREEZING RAIN
TO BECOME THE PREDOMINANT MODE OF WINTRY PRECIPITATION INTO THE
EVENING HOURS, AS EVIDENT VIA 22Z RAP FORECAST SOUNDINGS AND 23Z
MESOANALYSIS. SURFACE OBSERVATIONS DEPICT AN INCREASE IN FREEZING
RAIN ALREADY UNDERWAY ACROSS NORTHERN SC INTO CENTRAL NC, WITH
HEAVIER ICE ACCRETION RATES LIKELY THIS EVENING. FURTHERMORE,
HIGH-RESOLUTION MODEL GUIDANCE ALSO SHOWS A HIGH LIKELIHOOD OF .06
IN/3 H ICE ACCRETION RATES, ESPECIALLY IN THE 00-06Z TIME FRAME.
