TODAY & FRIDAY:
SURFACE COOLING COMBINED WITH A SHALLOW LAYER OF MOISTURE IS
RESULTING IN FOGGY CONDITIONS ACROSS CENTRAL ALABAMA THIS MORNING.
OCCURRENCES OF DENSE FOG ARE COMMON PER ASOS AND CAMERAS.
HAZARDOUS DRIVING CONDITIONS WILL EXIST THROUGH 9 AM THIS MORNING.
THROUGH THE REST OF TODAY, THE WEATHER SETUP ACROSS THE SOUTHERN
CONUS WILL PROMOTE CONTINUED VARIABLE CLOUDINESS WITH ANOTHER
DAY OF NEAR-RECORD HIGH TEMPERATURES. A MID-LEVEL IMPULSE WILL
RIDE THE NORTHERN PERIMETER OF 500 MB RIDGING CENTERED NEAR THE
YUCATAN, BRINGING CLUSTERS OF SHOWERS AND THUNDERSTORMS TODAY TO
THE TENNESSEE VALLEY. A FEW SHOWERS MAY OCCUR AS FAR SOUTH AS THE
278 CORRIDOR OF NORTH-CENTRAL ALABAMA.
ANOTHER IMPULSE COMES BY ON FRIDAY WITH A BETTER OFFERING OF
SHOWERS AND THUNDERSTORMS ACROSS CENTRAL ALABAMA. CAMS SHOW THIS
OCCURRING IN THE FORM OF MULTIPLE CLUSTERS OF ACTIVITY, WHICH
MATCHES THE MODELED CONFIGURATION OF THIS SYSTEM. WHILE A MODEST
AMOUNT OF WIND SHEAR WILL OVERSPREAD THE REGION, FORECAST
SOUNDINGS SUGGEST POOR INSTABILITY PROFILES; SO, SEVERE WEATHER IS
NOT ANTICIPATED THOUGH A FEW BENEFICIAL DOWNPOURS MAY DEVELOP.
THE WEEKEND:
IF THE FRONT MOVES SLOWLY ENOUGH, SATURDAY'S WEATHER MAY INCLUDE
LINGERING AREAS OF CLOUDINESS AND SOME LIGHT SHOWERS. MODELS
AGREE THAT BY SUNDAY WE'RE TOTALLY RAIN-FREE. TEMPERATURES OVER
THE WEEKEND REMAIN ABOVE SEASONAL NORMALS, BUT NOT TO THE MARGINS
OF EARLIER IN THE WEEK.
NEXT WEEK:
AN UPPER-LEVEL TROUGH NEAR THE PACIFIC NORTHWEST TODAY (NOV 20) IS
FORECAST TO TRACK ACROSS THE SOUTHWEST U.S. THIS WEEKEND AS A
CLOSED LOW AND THEN MOVE EAST EARLY TO MID NEXT WEEK AS SOME FORM
OF AN OPEN TROUGH. ENSEMBLES SHOW SHOWERS AND THUNDERSTORMS
AFFECTING OUR AREA DURING A TUESDAY INTO TUESDAY NIGHT TIMEFRAME.
THERE HAS BEEN VARIABILITY REGARDING THE MODELED STRUCTURE OF THE
TROUGH; THIS HEAVILY IMPACTS THE DETAILS OF THE FORECAST. RIGHT
NOW, THE MORE AGGRESSIVE SOLUTIONS COULD SUPPORT A LOW SEVERE
WEATHER RISK, BUT THAT'S IN CONTRAST TO MORE TAME AND NON-SEVERE
SOLUTIONS. THERE'S NOT QUITE ENOUGH THERE TO INTRODUCE A SEVERE
WEATHER RISK AT THIS TIME.
