AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
402 AM CST MON DEC 9 2013

.DISCUSSION...
LOW CLOUDS AND AREAS OF FOG WILL CONTINUE THROUGH MID
MORNING...MAINLY ACROSS THE WESTERN TWO THIRDS OF NORTH TEXAS
WHERE WINDS ARE LIGHT AND THE GROUND IS SATURATED IN MANY
LOCATIONS. WE WILL CONTINUE WITH A FREEZING FOG ADVISORY THROUGH
10 AM GENERALLY NORTHWEST OF A GAINESVILLE...WAXAHACHIE
TO GOLDTHWAITE LINE WHERE TEMPERATURES WILL REMAIN AT OR BELOW
FREEZING. WE WILL ALSO KEEP A DENSE FOG ADVISORY IN PLACE SOUTH
OF THE FREEZING FOG ADVISORY WHERE TEMPERATURES WILL REMAIN ABOVE
FREEZING BUT FOG WILL BE DENSE AT TIMES. ALL VISIBILITIES SHOULD
IMPROVE ABOVE 1 MILE BY 10 AM. MODEL GUIDANCE CONTINUES TO HOLD
CLOUDS IN PLACE AT MOST LOCATIONS THOUGH THE DAY WHICH WILL LIMIT
SURFACE HEATING...ESPECIALLY SINCE A REINFORCEMENT OF COOL AND DRY
AIR WILL ACCOMPANY A COLD FRONT TODAY. AFTERNOON HIGHS SHOULD WARM
ABOVE FREEZING IN ALL SPOTS BUT NOT AS MUCH AS PREVIOUSLY THOUGHT.

A COLD FRONT IS CURRENTLY MOVING ACROSS THE RED RIVER AS NOTED BY
THE DISCONTINUITY IN DEW POINTS. THE FRONT WILL ENTER NORTH TEXAS
QUIETLY AND DO LITTLE MORE THAN LOWER DEW POINTS AND BRING A
SLIGHTLY STRONGER NORTH TO NORTHEAST WIND. CLOUDS WILL BE ON THE
DECREASE TONIGHT AND TUESDAY AS AN UPPER LEVEL TROUGH MOVES EAST
OF THE REGION AND THE DRY AIR BEHIND THE COLD FRONT GETS DEEPER.
THESE CONDITIONS WILL ALLOW TEMPERATURES TO FALL INTO THE TEENS
AND 20S BY TUESDAY MORNING. THEREFORE...RESIDUAL WATER ON ROADS
WILL LIKELY FREEZE AND CONTINUE TO CREATE HAZARDOUS DRIVING
CONDITIONS IN SOME PLACES.

THE INCREASE IN SOLAR HEATING TUESDAY WILL RESULT IN AFTERNOON
HIGHS IN FROM THE MIDDLE 30S TO THE MIDDLE 40S WHICH WILL HELP THE
THAWING PROCESS ACROSS THE REGION. LOWS TUESDAY NIGHT WILL STILL
FALL BELOW FREEZING WITH MAINLY 20S EXPECTED.

A WEAK RIDGE OF HIGH PRESSURE WILL BEGIN TO BUILD OVER TEXAS
WEDNESDAY AHEAD OF A DEVELOPING UPPER TROUGH OVER BAJA. INCREASING
HEIGHTS AND ABUNDANT SUN WILL RESULT IN AFTERNOON HIGHS MAINLY IN
THE 40S. SUB-FREEZING TEMPS ARE EXPECTED AGAIN WEDNESDAY NIGHT.
HOWEVER...TEMPERATURES WILL QUICKLY WARM ON THURSDAY AS THE UPPER
RIDGE STRENGTHENS OVER TEXAS AND SOUTHEAST TO SOUTH WINDS RETURN.

RAIN CHANCES WILL RETURN TO NORTH TEXAS THURSDAY NIGHT/FRIDAY AS
LARGE SCALE LIFT AND LOW LEVEL MOISTURE BOTH INCREASE. THE UPPER
TROUGH WILL MOVE EAST ACROSS THE REGION SATURDAY AND ANOTHER COLD FRONT
WILL MOVE THROUGH. THE PASSAGE OF THE FRONT WILL INITIALLY BRING
ANOTHER CHANCE OF RAIN FOLLOWED BY DRIER AND COOLER AIR SATURDAY
NIGHT AND SUNDAY.
