DISCUSSION
DRY AND COOL CONDITIONS ARE FORECAST ACROSS NORTHERN ALABAMA WITH
LOW TEMPERATURES FROM THE LOWER 50S EAST TO NEAR 60 WEST. DRY
WEATHER IS EXPECTED IN THE MORNING. AN INCREASE OF ATMOSPHERIC
MOISTURE, ALONG WITH DAYTIME HEATING AND RESULTANT INSTABILITY,
AND AN APPROACHING SYSTEM WILL BRING CHANCES OF SHOWERS AND
THUNDERSTORMS IN THE LATE AFTERNOON. THE ACTIVITY SHOULD
OVERSPREAD THE AREA FROM WEST TO EAST FRIDAY EVENING. SOME OF THE
STORMS COULD PRODUCE STRONG GUSTY OUTFLOW WINDS AND HEAVY
DOWNPOURS.
MIXING HEIGHTS GENERALLY GREATER THAN 6000 FT AGL, AND TRANSPORT
WINDS AT OR ABOVE 15 MPH WILL PRODUCE DISPERSION RATES, RANGING
FROM GOOD WEST TO VERY GOOD EAST. FAIR TO GENERALLY GOOD
DISPERSION RATES ARE EXPECTED ON SATURDAY.
FOG POTENTIAL OVER THE NEXT FEW DAYS: LATE NIGHT PATCHY FOG
DEVELOPMENT COULD OCCUR IN SHELTERED AREAS ACROSS NORTHERN ALABAMA
LATE TONIGHT. MORE PATCHY FOG IS POSSIBLE LATE FRIDAY NIGHT INTO
EARLY SATURDAY MORNING.
POTENTIAL FOR RED FLAG CONDITIONS: IS NOT FORECAST AT THIS TIME.
