FIRE WEATHER PLANNING FORECAST FOR NORTHERN ALABAMA
NATIONAL WEATHER SERVICE HUNTSVILLE AL
316 AM CDT FRI APR 19 2019
DISCUSSION
LIGHT RAIN WILL CONTINUE BEHIND A STORM SYSTEM MOVING THROUGH GEORGIA
INTO THE DAYBREAK HOURS. THIS ACTIVITY IS EXPECTED TO BECOME MORE
SCATTERED IN NATURE THROUGH THAT PERIOD.
THEN AS THE SURFACE LOW ASSOCIATED WITH THIS SYSTEM MOVES NORTHWARD
INTO THE APPALACHIANS THROUGH THE DAY, ADDITIONAL RAIN SHOWERS ARE EXPECTED
TO DEVELOP OVER THE TENNESSEE VALLEY. VERY BREEZY AND RAW CONDITIONS
AREA EXPECTED TODAY WITH SUSTAINED NORTHWESTERLY WINDS BETWEEN 10 AND 15
MPH WITH GUSTS UP TO 30 MPH EXPECTED. GOOD TRANSPORT WINDS WILL BE
ACCOMPANIED BY MIXING HEIGHTS AROUND 2000 FEET IN MOST LOCATIONS (THOUGH
MIXING HEIGHTS WILL BE A BIT HIGHER AROUND 3000 FEET IN NORTHEASTERN
ALABAMA). GENERALLY GOOD DISPERSION INDEX VALUES ARE EXPECTED. AN
ADDITIONAL HALF TO ONE INCH OF RAINFALL IS POSSIBLE TODAY THROUGH
TONIGHT.
AS CLOUDS MOVE NORTHEAST OF THE AREA ON SATURDAY AND MIXING HEIGHTS
INCREASE, DISPERSION INDEX VALUES WILL BE MUCH IMPROVED. TRANSPORT WINDS
WILL REMAIN FAIRLY STRONG AROUND 20 MPH. A FEW LINGERING SHOWERS AND
SOME CLOUDS COULD LINGER IN NORTHEASTERN ALABAMA, BUT MIXING HEIGHT
SHOULD STILL BE VERY HIGH. THE AIRMASS IN PLACE ON SATURDAY WILL BE
MUCH DRIER THOUGH, WITH MINIMUM RELATIVE HUMIDITY VALUES DROPPING TO
BETWEEN 29 AND 35 PERCENT. THE EXCEPTION AGAIN WILL BE NORTHEASTERN
ALABAMA, WHICH WILL BE MORE MOIST WITH RELATIVE HUMIDITY VALUES CLOSER
TO 45 PERCENT. NORTHWEST WINDS WILL REMAIN BREEZY AND SHOULD BE 15 TO
20 MPH WITH GUSTS TO AROUND 25 MPH.
FOG POTENTIAL OVER THE NEXT FEW DAYS: SOME PATCHY FOG DUE TO LOW CLOUD
COVER IS POSSIBLE IN HIGHER TERRAIN TODAY AND TONIGHT.
POTENTIAL FOR RED FLAG CONDITIONS: NONE ARE EXPECTED AT THIS TIME.
