.AVIATION DISCUSSION...

THE LINE OF SHOWERS THAT MOVED THROUGH MUCH OF CENTRAL ALABAMA
THIS EVENING IS FINALLY STARTING TO DISSIPATE. AS THE LINE PUSHED
SOUTHWARD, WIND GUSTS UP TO 40 MPH WERE OBSERVED ON SOME SURFACE
OBSERVATIONS. THIS MAY HAVE BEEN DUE TO THE AMOUNT OF DRY AIR
ALOFT MIXING STRONGER WINDS DOWN TO THE SURFACE ALONG THE LINE OF
SHOWERS. GUSTS BETWEEN 20 AND 30 KNOTS ARE STILL BEING REPORTED
ACROSS SOUTHERN ALABAMA AT THIS HOUR. THE ACTUAL COLD FRONT ITSELF
IS LAGGING BEHIND THAT LINE OF SHOWERS, CURRENTLY BEING BEING
ANALYZED ACROSS NORTHERN MISSISSIPPI AND MOVING INTO NORTHWEST
ALABAMA. 30S AND 40S DEWPOINTS ARE BEING OBSERVED TO THE NORTH OF
THE FRONT, AND THAT DRY AIR WILL ADVECT SOUTHWARD THROUGH THE
NIGHT WITH DECREASING CLOUDINESS.

FOR THE FORECAST, HAVE UPDATED POPS TO REFLECT CURRENT CONDITIONS
AND HAVE DECREASED POPS THROUGH THE OVERNIGHT HOURS AS THE SHOWERS
EVENTUALLY DISSIPATE. OVERNIGHT LOWS WERE DECREASED BY A DEGREE OR
TWO ACROSS THE NORTHERN COUNTIES BASED ON THE LATEST GUIDANCE. MID
40S CAN NOW BE EXPECTED NORTH TO THE LOWER 50S SOUTH.

56/GDG

SHOULD PREVENT WIDESPREAD VIS REDUCTIONS.

WINDS WILL INCREASE AGAIN TOMORROW AFTERNOON...WITH DRY CONDITIONS
CONTINUING.
