DISCUSSION
A WEAKENING DOME OF HIGH PRESSURE ACROSS THE TN VALLEY WILL
MAINTAIN CALM CONDITIONS THIS MORNING, WITH A GRADUAL INCREASE IN
NW WINDS LATER TODAY AHEAD OF A WEAK REINFORCING COLD FRONT.
ALTHOUGH ABUNDANT SUNSHINE (WARMING TEMPS INTO THE L-M 90S) AND
DRY PROFILES WILL CREATE MINRH IN THE 40-50% RANGE TODAY, A FEW
SHOWERS ARE EXPECTED TO EVOLVE ALONG THE COLD FRONT AS IT DRIFTS
SOUTHWARD ACROSS NORTH AL OVERNIGHT (WITH THE GREATEST CHANCE FOR
A THUNDERSTORM OR TWO EXPECTED TO BE ACROSS NW AL LATE THIS
AFTERNOON/EARLY THIS EVENING). LIGHT NORTHERLY WINDS IN THE WAKE
OF THE FRONT WILL ADVECT AN EVEN DRIER AIRMASS INTO THE REGION
TOMORROW, WITH MINRH DROPPING INTO THE 35-45% RANGE. SMOKE
DISPERSION WILL BE GOOD BOTH TODAY AND TOMORROW, WITH MIXING
HEIGHTS OF 6500-7500 FT AND TRANSPORT WINDS OF 5-10 MPH.
FOG POTENTIAL OVER THE NEXT FEW DAYS: PATCHY, LOCALLY DENSE FOG
WILL IMPACT SMALL PARTS OF NORTH AL EARLY THIS MORNING. CONDITIONS
APPEAR LESS FAVORABLE FOR FOG DEVELOPMENT EARLY SUNDAY MORNING.
POTENTIAL FOR RED FLAG CONDITIONS: NONE AT THIS TIME.
