Freezing Rain This Morning


Winter Wx Advisories have been hoisted for the overnight hours from 3AM - 5PM tomorrow for about a tenth of an inch of freezing rain and minor sleet accumulation.

Davie and Rowan counties under WWA's - either the same or Freezing Rain Advisories out for the majority of NC. Only difference being the NWS thinks it is possible some sleet/snow mixes in at the beginning in WWA counties and just freezing rain in others - talking very minimal before turns to freezing rain, which will also be minimal.

However, if enough precip falls it could make bridges/roads icy so be careful in the morning. Most likely just a tree branch / elevated surfaces ice glaze expected.

The NWS forecast for Rowan/Davie (GSP) has issued the following accumulation / forecast map, which lists Farmington as the top ice winner with expected .11" and Salisbury close but a mere hundredth off... Right...


So mainly nuisance type event with temps rising above freezing and therefore erasing any ice by the mid-afternoon if not sooner.

Current temps are below 32ยบ now most places or will be per wet bulb temps. 


Here is the WPC Winter Weather Statement and map concerning the chances of having .25: of ice or greater - not much.  Only expect .1-.2" freezing rain overnight and tomorrow morning mainly.

DESPITE THE RETREATING HIGH AND NOT VERY STRONG WARM NOSE WITH  FLAT SYSTEM... ARCTIC/SHALLOW AIR MASS IS EXPECTED TO HOLD STRONG AND COULD REPRESENT THE THREAT OF ICING FROM THE WRN CAROLINAS INTO THE NRN MID-ATL STATES. ITS THE CORRIDOR WEST OF I95 THATS MOST WORRISOME ESPECIALLY FROM WRN NC THROUGH SWRN VA INTO THE DC/BAL AREAS AND POSSIBLY EXTENDING INTO SERN PA. WPC GENERALLY FOLLOWED THE GFS HERE ON QPF AND A BLEND OF 12Z THERMAL PROFILES FOR A .10 TO .25 ACCUMULATIONS FROM CLT TO PHL
