ADJUSTMENTS HAVE BEEN MADE TO OVERNIGHT LOWS TO RAISE THEM 2-3
DEGREES ACROSS MOST OF THE CWA. LOOKING UPSTREAM IT IS CURRENTLY
42F AT NASHVILLE AND 35F AT INDIANAPOLIS...WHICH IS THE SOURCE
REGION FOR THE AIRMASS COMING OUR WAY. WITH A STRONG PRESSURE
GRADIENT IN PLACE AND A WELL-MIXED BOUNDARY LAYER TYPICAL OF COLD
ADVECTION REGIMES...SEE NO REASON HAVE WIDESPREAD FREEZING
TEMPERATURES IN OUR FORECAST. NAM FORECAST SOUNDINGS INDICATE A
MORE MIXED BOUNDARY LAYER COMPARED TO THE GFS AT 12Z SATURDAY...
WHICH SHOULD BE MORE REPRESENTATIVE OF THE SITUATION. OVERNIGHT
LOWS ARE NOW BASED HEAVILY ON THE RAW NAM 2M TEMPS. WITH 850MB
TEMPS IN THE -4C TO -6C RANGE ACROSS THE NORTH AND NORTHEAST...
HIGHER ELEVATIONS WILL SEE FREEZING TEMPERATURES. THE FREEZE
WARNING FOR TONIGHT HAS BEEN TRIMMED BACK TOWARD THE NORTH AND
REMAINS IN PLACE FOR OTHER COUNTIES MAINLY FOR THESE HIGHER
ELEVATIONS. A WIDESPREAD FREEZE IS STILL EXPECTED SUNDAY MORNING
AS WINDS BECOME MUCH LIGHTER.
