DISCUSSION...
CLOUDY AND COOL TODAY AS CLOUDS HAVE MANAGED TO HANG AROUND FOR
MOST OF THE DAY HOLDING BACK THE HEATING. THIS SHIELD OF CLOUDS
WILL BREAK FROM WEST TO EAST AS THE UPPER LEVEL LOW CONTINUES
IT`S TRACK OFF TO THE NORTHEAST THIS EVENING. A VERY COLD START TO
CHRISTMAS MORNING WITH CLEAR SKIES AND LIGHT WINDS... TEMPERATURES
WILL FALL INTO THE 30S WITH FROST EXPECTED ACROSS CENTRAL
LOUISIANA AND THE LAKES REGION IN SOUTHEAST TEXAS... MID 30S ALONG

SINCE WE ARE IN A VERY PROGRESSIVE PATTERN IN THE ATMOSPHERE...
THE SURFACE HIGH OVER DEEP SOUTH TEXAS IS EXPECTED TO MOVE INTO
THE FLORIDA PANHANDLE BY TOMORROW AFTERNOON WITH WINDS SWINGING
AROUND TO THE SOUTHEAST. IN ADDITION WITH THE LOSS OF CLOUDS...THIS
WILL ALLOW THE SUN TO WARM UP THE REGION WITH TEMPS NEAR 60 BY
THE AFTERNOON HOURS.

THE WARM UP WILL CONTINUE INTO FRIDAY WITH OVERNIGHT LOWS INTO
THE 40S AND THE DAYTIME HIGHS EXPECTED INTO THE MID TO UPPER 60S.
SOUTHERLY WINDS FROM THE EXITING HIGH WILL DRAG MOISTURE OFF THE
