FIRE WEATHER PLANNING FORECAST FOR ALABAMA
NATIONAL WEATHER SERVICE HUNTSVILLE AL
426 AM CDT TUE AUG 25 2026
DISCUSSION
SURFACE HIGH PRESSURE (CURRENTLY CENTERED ACROSS THE UPPER OH
VALLEY) WILL GRADUALLY SPREAD EASTWARD TODAY. ALTHOUGH THE
INFLUENCE OF THE HIGH WILL PROVIDE ONE MORE DAY OF DRY WEATHER
(WITH MINRH VALUES OF 40-50%), A PASSING UPPER-AIR DISTURBANCE
WILL BRING BROKEN-OVERCAST MID-LEVEL CLOUDS AND PERHAPS A LIGHT
SHOWER OR TWO TO THE REGION THIS MORNING. AS THE SURFACE HIGH
SHIFTS FURTHER EASTWARD TONIGHT, LIGHT SOUTHEASTERLY WINDS WILL
RETURN AND ADVECT A MOIST AIRMASS BACK INTO THE REGION ON
WEDNESDAY. THIS WILL SET THE STAGE FOR AN INCREASING COVERAGE OF
SHOWERS AND THUNDERSTORMS, BEGINNING DURING THE LATE MORNING HOURS
AND CONTINUING THROUGHOUT THE AFTERNOON. WITH THE EXCEPTION OF
NORTHEAST AL (WHERE SMOKE DISPERSION WILL BE FAIR TODAY),
GENERALLY GOOD DISPERSION INDICES ARE PREDICTED DUE TO MIXING
HEIGHTS OF 6000-7000 FT AND TRANSPORT WINDS OF 5-10 MPH.
FOG POTENTIAL OVER THE NEXT FEW DAYS: THERE IS LITTLE-NO CONCERN
FOR FOG DEVELOPMENT EARLY THIS MORNING, BUT CONDITIONS MAY SUPPORT
DEVELOPMENT OF PATCHY FOG IN RURAL AREAS EARLY WEDNESDAY MORNING.
POTENTIAL FOR RED FLAG CONDITIONS: NONE AT THIS TIME.
