.DISCUSSION...

HIGH CLOUDS CONTINUE TO STREAM IN FROM THE WEST THIS EVENING AS A
WEAK UPPER SHORTWAVE ROTATES AROUND THE UPPER LEVEL LOW THAT IS
CURRENTLY CENTERED ACROSS CENTRAL OKLAHOMA BASED ON THE LATEST
IR SATELLITE IMAGERY. THIS UPPER LEVEL LOW IS HELPING TO TRIGGER
STRONG TO SEVERE STORMS ACROSS NORTHERN TEXAS THIS EVENING. QUIET
WEATHER WILL BE THE TREND FOR CENTRAL ALABAMA OVERNIGHT
TONIGHT...WITH ONLY THE WIDESPREAD HIGH CLOUDS INCLUDED IN THE
FORECAST. DUE TO THE EXPANSIVE CLOUD COVER AND A BIT MORE MOISTURE
AT THE SURFACE WE SHOULD NOT BE ALLOWED TO COOL AS MUCH
TONIGHT...AND THIS HAS BEEN NOTICEABLE FROM THE DIURNAL TRENDS OVER
THE PAST FEW HOURS. I HAVE RAISED LOW TEMPERATURES A COUPLE OF
DEGREES FOR MOST LOCATIONS DUE TO THIS TREND. I HAVE ALSO RAISED
DEWPOINTS A BIT DURING THE OVERNIGHT BASED ON THE LATEST GUIDANCE
AND OBSERVATION TRENDS. UPDATES ARE ALREADY OUT.
