Awake at 3:22... Pouring here in Saluda at 31.1. Ice storm warning issued... Looked out side and saw a little ice on the deck rail. Tended the wood-stove looked outside ten minutes later to 1/2 icicles on deck rail. Going to be a long night... This might be one of those events where the micro climate up here stays below freezing well into late tomorrow afternoon.

AS OF 400 AM...THE COMPLEX OCCLUDED LOW AND WEDGE COMBO SYSTEM IS
LIVING UP TO AND SURPASSING EXPECTATIONS A LITTLE THIS MORNING. THE
COOLING ACROSS THE NC MTNS AND THE AMOUNT OF PRECIP EXPECTED THE
NEXT SEVERAL HRS WILL COMBINE TO GIVE A GOOD AMOUNT OF -FZRA ACROSS
THE CENTRAL MTNS AND HIGHER ELEV OF THE SRN FOOTHILLS...ALONG WITH
THE ESCARPMENT AREA NEAR THE SC/NC BORDER. STILL EVALUATING THE NRN
MTNS AND HIGH ELEV NRN FOOTHILLS FOR A POSSIBLE WARNING
UPGRADE...BUT FOR NOW WILL COUNT OF THE PRECIP/ICE ACCUMS REMAINING
THE HIGHEST ACROSS THE AREAS TO THE SOUTH WHERE THE BEST LIFT AND
ISENT OMEGA EXIST. ALSO...WILL ADD A FREEZING RAIN ADVISORY FOR
AREAS EAST OF THE MTNS ACROSS THE NRN/SRN FOOTHILLS AND THE NC
PIEDMONT WEST OF THE I-77 CORRIDOR.

THE MODELS ARE DOING AN ADEQUATE JOB WITH THE DYNAMICS OF THIS
SYSTEM THROUGH THE NEAR TERM AND GIVE GOOD CONFIDENCE WITH THE
WARMING TAKING OVER THE LLVLS BY 14Z OR SO AND CHANGING THE MAJORITY
OF LOCALES TO ALL -RA. HOWEVER...THERE MAY BE SOME LINGERING POCKETS
OF -FZRA ACROSS ISOL MTN VALLEYS THROUGH LATE MORNING. HAVE NOTICED
THE WETBULB FREEZING ZONE EXPANDING IN COVERAGE THIS MORNING INTO
THE UPSTATE AND THREATENING AREAS AROUND CLT AND THE I-77. THIS WILL
BE MONITORED FOR A POSSIBLE FZRA ADVISORY INCLUSION.

 

Latest from GSP, they make mention of possibly expanding the freezing rain advisory for the upstate towards charlotte

 

**I'm at 32.1 right now and wet bulbing at 31.6**

McDowell County Schools going in 2 hours late...

We have been holding at 32.4 for about the past 3 hours. Ice is starting to build up on trees, being that this is a borderline event, the ground itself will prob stay wet. That and the rainfall rates picking up will also help.

 

I also think we wetbulb a bit lower due to the fact that it started to drizzle late yesterday evening before the main batch of heavier rain came in.
