the higher elevations of southwest virginia and northeast tennessee.

kjan:

Beyond wednesday...models suggest an arctic airmass
will settle into the region suggesting lower teens/single digits for
lows and 20s for highs. Will be interesting to see how the models
evolve over the next week and what the cold air will look like on the
next few runs.

From the Birmingham NWS….two words, “Epic Cold”:
BEYOND MONDAY…A PATTERN EVOLUTION REALLY BEGINS TO TAKE SHAPE
WITH A BULGING WEST COAST RIDGE AND EASTERN U.S. TROUGH
DEVELOPING. SEVERAL RE-ENFORCING SHOTS OF COLDER AIR WILL BE
POSSIBLE NEXT WEEK UNDER THIS SCENARIO. THE GFS REALLY STEPS OUT
ON A LIMB WITH SOME OF THE LOWEST 1000-850 THICKNESSES I`VE EVER
SEEN (THIS FAR SOUTH) BY WEDNESDAY MORNING. HOWEVER…GONE IS THE
GULF LOW FROM YESTERDAY`S 00Z GFS RUN WHICH ADDS TO THE
CREDIBILITY OF THE ECMWF. NONETHELESS…LOOK FOR A CHANGE TO BELOW
AVERAGE TEMPERATURES NEXT WEEK.
