FIRE WEATHER PLANNING FORECAST FOR ALABAMA
NATIONAL WEATHER SERVICE HUNTSVILLE AL
344 AM CDT WED AUG 19 2026
DISCUSSION
THE HEAT AND DEEPER MOISTURE WILL MAKE A RETURN TODAY. UNDER
PARTLY CLOUDY SKIES, HIGH TEMPERATURES SHOULD RISE INTO THE
LOW/MID 90S, WITH HEAT INDEX VALUES UP TO 107 OVER NW ALABAMA THIS
AFTERNOON. THE MOISTURE PLUS INTERACTION WITH PASSING BOUNDARIES
WILL BRING LOWER END SHOWER/THUNDERSTORM CHANCES ACROSS PORTIONS
OF NW ALABAMA THIS AFTERNOON. SOME OF THESE STORMS COULD BECOME
STRONG TO MARGINALLY SEVERE, WITH STRONG GUSTY WINDS THE MAIN
THREAT. LIGHT WINDS FROM THE SURFACE TO TRANSPORT LAYER WILL
RESULT IN FAIR TO GENERALLY GOOD SMOKE DISPERSION RATES TODAY.
LOW END CHANCES FOR ADDITIONAL SHOWERS/THUNDERSTORMS ARE FORECAST
TONIGHT, AS YET ANOTHER DISTURBANCE NEARS THE AREA. SOME OF THESE
STORMS COULD PRODUCE STRONG GUSTY WINDS AND HEAVY DOWNPOURS.
FOG POTENTIAL OVER THE NEXT FEW DAYS: A RISK FOR PATCHY OVERNIGHT
TO EARLY MORNING FOG CONTINUES, DUE TO PLENTY OF ENVIRONMENTAL
MOISTURE AND HIGH RELATIVE HUMIDITIES IN THE NIGHT. FOG WOULD BE
MORE PREVALENT IN SHELTERED LOCATIONS, AND/OR IN AREAS THAT
RECEIVE WETTING RAINFALL. ANY FOG THAT FORMS SHOULD QUICKLY
DISSIPATE SHORTLY AFTER SUNRISE.
POTENTIAL FOR RED FLAG CONDITIONS: NOT FORECAST AT THIS TIME.
