AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX

.DISCUSSION...
ABOUT HALF OF NORTH TEXAS SAW SNOW YESTERDAY WITH MAXIMUM SNOWFALL
TOTALS AROUND 9 INCHES FROM JACKSBORO TO BOWIE. LOCATIONS THAT
SAW SEVERAL INCHES OF SNOW WILL CONTINUE TO SEE A WHITE CHRISTMAS
THROUGH AT LEAST THE MORNING HOURS AND LIKELY LONGER IN THE
NORTHWESTERN COUNTIES. THE SNOW PACK WILL KEEP HIGH TEMPERATURES
LOWER THAN EXPECTED TODAY AND HAVE SIGNIFICANTLY TRENDED HIGH
TEMPERATURES DOWN ACROSS THE NORTHWESTERN HALF OF NORTH TEXAS.
OF COURSE THE MAIN CONCERN THIS MORNING ARE THE ICY ROADS THAT
COVER MOST OF THE AREA WHERE SNOW FELL YESTERDAY. MOST ROADS ARE
COVERED IN ICE PROVIDING TREACHEROUS DRIVING CONDITIONS AND
RESIDENTS ARE URGED TO AVOID TRAVEL AT LEAST THIS MORNING IF POSSIBLE.
VERY DRY AIR /DEWPOINTS IN THE SINGLE DIGITS AND LOWER TEENS/ IS
WORKING ITS WAY INTO NORTH TEXAS AND THIS DRY AIR WILL HOPEFULLY
HELP SUBLIMATE SOME OF THE ICE. ALSO...THE PRESENCE OF CLEAR SKIES
TODAY WILL ALLOW THE SUN TO HEAT THE SURFACE AND WE EXPECT
CONDITIONS TO HAVE SIGNIFICANTLY IMPROVED BY THE LATE MORNING
HOURS /DESPITE AIR TEMPS STILL BELOW OR NEAR FREEZING/.
HOWEVER...THERE WILL LIKELY STILL BE SOME ICY SPOTS DURING THE
AFTERNOON HOURS AND CAUTION SHOULD BE OBSERVED ALL DAY.
THE UPPER LEVEL LOW THAT WAS RESPONSE FOR YESTERDAYS SNOW STORM IS
NOW RAPIDLY MOVING NORTH THROUGH THE MIDWEST AND WILL MERGE WITH
ANOTHER UPPER LEVEL LOW OVER THE NORTHERN PLAINS. THIS LARGE LOW
PRESSURE SYSTEM WILL WANDER AROUND THE NORTHERN PLAINS/MIDWEST
THROUGH THE WEEKEND...KEEPING NORTH TEXAS IN NORTHWEST AND WEST
FLOW. A FEW SHOTS OF REINFORCING COOL AND DRY AIR WILL ARRIVE IN
THE NEXT FEW DAYS. TEMPERATURES WILL REMAIN FAIRLY CONSISTENT
THROUGH MONDAY WITH HIGHS IN THE 40S/LOWER 50S AND LOWS IN THE
20S/LOWER 30S. HOWEVER...LOCATIONS IN THE NORTHWEST COULD SEE LOWS
TONIGHT IN THE TEENS.
A SURFACE LOW PRESSURE SYSTEM WILL MOVE THOUGH THE NORTHERN GULF
OF MEXICO THIS WEEKEND BRINGING SOME RAIN TO SOUTH AND SOUTHEAST
TEXAS SATURDAY AND SUNDAY. IT IS POSSIBLE THAT A FEW SHOWERS MAY
WORK THEIR WAY INTO CENTRAL TEXAS /OUR SOUTHERN COUNTIES/ ON
SATURDAY BUT HAVE KEPT A DRY FORECAST FOR NOW.
THE NEXT PRECIPITATION EVENT AND POSSIBLE WINTER WEATHER EVENT
LOOKS TO BE TUESDAY AND POSSIBLY INTO WEDNESDAY. THE ECMWF IS
SLIGHTLY FASTER AND MORE AGGRESSIVE WITH THIS SYSTEM AND HAVE
CONTINUED TO KEEP THE FORECAST SIMILAR TO THE ECMWF. IT STILL
LOOKS LIKE A MIX OF RAIN/SNOW WILL OCCUR NORTH OF INTERSTATE 20
WITH A RAIN/SLEET MIX SOUTH OF INTERSTATE 20 BUT PRECIP TYPES WILL
LIKELY BE ADJUSTED IN THE COMING DAYS.
