So ahhh this is the Sat night forecast....WTH kinda air m is this
Saturday Night Clear, with a low around 27. West wind 6 to 15 mph, with gusts as high as 22 mph.
of course the AFD says the winds decouple late but still windy and that cold is pretty nasty stuff in Jan much less April.
MODEL THICKNESSES HAVE BEEN FAIRLY CONSISTENT IN ITS DEPICTION OF
LOW LEVEL THICKNESSES IN THE 1285-1290M RANGE BY EARLY SUNDAY. THESE
VALUES HISTORICALLY SUPPORT MIN TEMPS SOLIDLY IN THE MID 20S. MOS
GUIDANCE APPEARS A TAD TOO WARM CONSIDERING THE THICKNESSES THOUGH
THIS MAY BE DUE IN PART TO A LIGHT BIT PERSISTENT NLY FLOW
OVERNIGHT. APPEARS THAT THE SFC HIGH BUILDS FAR ENOUGH INTO CENTRAL
NC TO CAUSE THE SFC WINDS TO DECOUPLE...ESPECIALLY ACROSS THE
PIEDMONT AFTER MIDNIGHT. A FREEZE WATCH/WARNING WILL LIKELY BE
ISSUED ON FRIDAY FOR SATURDAY NIGHT
