FIRE WEATHER PLANNING FORECAST FOR ALABAMA
NATIONAL WEATHER SERVICE HUNTSVILLE AL
215 PM CDT FRI MAY 22 2026
DISCUSSION
CLUSTERS OF MODERATE-HEAVY SHOWERS AND EMBEDDED THUNDERSTORMS
WILL CONTINUE TO SPREAD NORTHEASTWARD ACROSS NORTHERN AL THIS
AFTERNOON, BEFORE DIMINISHING IN COVERAGE EARLY THIS EVENING.
HOWEVER, REDEVELOPMENT OF ADDITIONAL CONVECTION MAY OCCUR EARLY
SATURDAY MORNING AS A SLOW-MOVING PREFRONTAL TROUGH BEGINS TO
DRIFT SOUTHEASTWARD INTO THE REGION. THIS ACTIVITY IS EXPECTED TO
EXPAND IN COVERAGE LATE TOMORROW MORNING, WITH A COMPARATIVELY
LOWER COVERAGE OF THUNDERSTORMS DURING THE AFTERNOON. IN THE WAKE
OF THIS CONVECTION, A TEMPORARY PERIOD OF DRY WEATHER IS
ANTICIPATED SATURDAY NIGHT, BEFORE WIDESPREAD RAIN AND
THUNDERSTORMS RETURN TO THE REGION ON SUNDAY. DUE TO AN ABUNDANT
COVERAGE OF PRECIPITATION AND LOW CLOUDS, MIXING HEIGHTS WILL ONLY
REACH THE 3500-4500 FT RANGE ON A DAILY BASIS, AND THIS (ALONG
WITH TRANSPORT WINDS ~10 MPH) WILL RESULT IN FAIR SMOKE DISPERSION
BOTH DAYS THIS WEEKEND. IN THE EXTENDED PORTION OF THE FORECAST,
WE EXPECT A WET WEATHER PATTERN TO CONTINUE FOR MUCH OF NEXT WEEK,
WITH DAILY CHANCES FOR WETTING RAINFALL IN THE 60-90% RANGE.
FOG POTENTIAL OVER THE NEXT FEW DAYS: FOG MAY DEVELOP ACROSS
PORTIONS OF THE AREA EARLY THIS EVENING, IF THERE IS A BRIEF
WINDOW OF CLEARING PRIOR TO THE REDEVELOPMENT OF LOW STRATUS
CLOUDS LATER THIS EVENING. CONDITIONS WILL BE MORE FAVORABLE FOR
FOG FORMATION LATE SATURDAY NIGHT-EARLY SUNDAY MORNING.
POTENTIAL FOR RED FLAG CONDITIONS: NONE AT THIS TIME.
