.DISCUSSION...

HOPE EVERYONE HAD/IS HAVING A MERRY CHRISTMAS. A NICE DAY OUT
THERE WITH TEMPERATURES THIS AFTERNOON RANGING FROM THE UPPER 40S
TO MID 50S. COOL AGAIN TONIGHT WITH LOWS IN THE 30S AND FRIDAY IS
A VERY NICE DAY WITH AFTERNOON HIGHS NEAR 60.

A LONGWAVE TROUGH WILL AMPLIFY OVER THE WESTERN CONUS TODAY AND
FRIDAY WITH BULGING RIDGE BUILDING OVER CUBA AND SOUTHERN FLORIDA.
MID AND UPPER LEVEL SOUTHWESTERLY FLOW WILL GRADUALLY BRING
MOISTURE BACK TO THE REGION WITH CLOUD COVER RETURNING FRIDAY
EVENING. A SERIES OF IMPULSES ROTATING THROUGH THE TROUGH WILL
TRACK FROM THE WESTERN GULF NORTHEASTWARD. WITH CONTINUED MOIST
FLOW AND THE ADDED LIFT ASSOCIATED WITH THE SHORTWAVES...RAIN WILL
RETURN TO CENTRAL ALABAMA BY MID DAY SATURDAY. THE WEEKEND
CONTINUES TO LOOK WET WITH ANOTHER ONE TO TWO INCHES POSSIBLE
THROUGH SUNDAY NIGHT...ESPECIALLY OVER THE NORTHERN HALF OF THE
CWA WHERE THE BEST CONVERGENCE WILL BE NEAR A SURFACE FRONT. WILL
CONTINUE TO MENTION ISOLATED THUNDER BUT THERE IS NO SEVERE
THREAT.

THE FRONT FINALLY CLEARS THE AREA ON MONDAY...AND A FEW DRY OR
MOSTLY DRY PERIODS ARE EXPECTED TO BEGIN THE WEEK. TRENDS FROM THE
12Z CYCLE WAS TO SLOW DOWN THE ARRIVAL OF THE NEXT SYSTEM UNTIL
THE SECOND HALF OF THURSDAY. AT THIS TIME IT WOULD BE A COLD RAIN
THURSDAY EVENING AND FRIDAY MORNING WITH THE AIRMASS STILL TOO WARM
FOR ANYTHING FROZEN. TEMPERATURES NEXT WEEK LOOK SEASONABLE.
