FIRE WEATHER PLANNING FORECAST FOR ALABAMA
NATIONAL WEATHER SERVICE HUNTSVILLE AL
412 AM CDT SAT MAR 21 2026
DISCUSSION
LIGHT-MODERATE SOUTHWESTERLY FLOW WILL CONTINUE ACROSS NORTHERN
AL FROM EARLY THIS MORNING THROUGH THE DAY ON SUNDAY, WITH OUR
REGION LOCATED TO THE NORTH OF A HIGH CENTERED OVER THE GULF AND
TO THE SOUTH OF AN APPROACHING COLD FRONT. ALTHOUGH THIS WILL
CONTRIBUTE TO A VERY WARM AND INCREASINGLY MOIST AIRMASS, CHANCES
FOR WETTING RAINFALL APPEAR VERY LOW AT THIS TIME. AFTERNOON MIN
RH VALUES WILL BE IN THE 35-45% RANGE BOTH TODAY AND SUNDAY, ALONG
WITH GOOD-VERY GOOD SMOKE DISPERSION INDICES (DUE TO TRANSPORT
WINDS OF 15-25 MPH AND HIGH MIXING HEIGHTS OF 4500-5500 FT). IN
THE EXTENDED PERIOD, A COLD FRONT IS EXPECTED TO CROSS THE REGION
EARLY MONDAY MORNING, BRINGING A COOLER AIRMASS BUT ONLY A VERY
LOW CHANCE FOR RAIN TO FAR NORTHEAST AL. SLIGHTLY GREATER CHANCES
FOR SHOWERS AND THUNDERSTORMS WILL OCCUR FROM TUESDAY-FRIDAY, AS A
SERIES OF DISTURBANCES TRACK SOUTHEASTWARD ACROSS THE REGION IN
NORTHWEST FLOW ALOFT.
FOG POTENTIAL OVER THE NEXT FEW DAYS: BRIEF DEVELOPMENT OF PATCHY
FOG MAY OCCUR IN WIND-PROTECTED VALLEYS EARLY THIS MORNING AND
EARLY SUNDAY MORNING.
POTENTIAL FOR RED FLAG CONDITIONS: NONE AT THIS TIME.
