AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
309 AM CST SUN DEC 13 2015

.DISCUSSION...
SQUALL LINE MOVING THROUGH MUCH OF NORTH AND CENTRAL TEXAS WILL
CONTINUE TO MOVE STEADILY EAST THROUGH THE REMAINDER OF THE
MORNING HOURS. RAIN AND THUNDERSTORMS ARE EXPECTED TO END AROUND 9
AM FOR AREAS WEST OF I-35/I-35W. TO THE EAST...LIGHT RAIN WILL
LINGER FOR A FEW MORE HOURS BEFORE DIMINISHING AFTER NOON. THE
HIGH TEMPERATURE FOR TODAY HAS ALREADY BEEN ACHIEVED...AS DAYTIME
TEMPERATURES WILL BE LIMITED TO THE LOWER 60S. IN THE RECORD
BOOKS...TODAY WILL GO DOWN WITH HIGHS IN THE 70S...BUT YOU AND I
WILL KNOW BETTER.

ONCE THE RAIN STOPS...THE WINDS WILL BEGIN TO INCREASE ESPECIALLY
IN THE WESTERN THIRD OF THE AREA. WIND GUSTS TO AROUND 35 MPH ARE
POSSIBLE FROM EASTLAND COUNTY TO MILLS COUNTY. OTHER AREAS WILL
SEE WIND GUSTS TO AT LEAST 25 MPH AT TIMES.

THE REMAINDER OF THE FORECAST IS RELATIVELY QUIET. THE UPPER LOW
AND ASSOCIATED SHORT WAVE TROUGH WILL MOVE EAST AND BRING THIS
RAIN TO AN END. HIGH PRESSURE IS BACK ON MONDAY AND THE NEXT
SYSTEM BEGINS TO ARRIVE ON TUESDAY. THIS SYSTEM WILL HAVE SOME
MOISTURE WITH IT AND WILL CONTINUE TO KEEP SMALL CHANCES FOR RAIN
GOING IN THE EAST AND SOUTHEAST. THIS SYSTEM WILL MOVE THROUGH
QUICKLY...ALLOWING FOR HIGH PRESSURE TO RETURN FOR THE LATER HALF
OF THE WEEK.

.CLIMATE...
AS OF 3 AM...THE GAINESVILLE AIRPORT HAS RECEIVED 0.19 INCHES OF
RAIN...WHICH BRINGS THE TOTAL IN GAINESVILLE TO OVER 80 INCHES FOR
THE YEAR.

THE LOW TEMPERATURE AT DFW AIRPORT ON SATURDAY WAS 70 DEGREES.
THIS BROKE THE DAILY RECORD FOR THE 12TH OF DECEMBER...AND ALSO
BROKE THE RECORD FOR THE WARMEST LOW TEMPERATURE IN DECEMBER. THE
FORMER RECORD WAS 69 DEGREES FOR THE LOW ON DECEMBER 16 1924

.AVIATION...
/ISSUED 1129 PM CST SAT DEC 12 2015/
/06Z TAFS/

SHOWERS AND ISOLATED THUNDERSTORMS ARE DEVELOPING ACROSS THE
REGION IN ADVANCE OF A LINE OF STORMS. WIND SPEEDS WILL ALSO BE ON
THE INCREASE OVER THE NEXT FEW HOURS AND ARE EXPECTED TO SHIFT FROM
SOUTHEAST TO SOUTHWEST AHEAD OF THE SQUALL LINE. THE LINE OF
STORMS IS STILL ON TRACK TO AFFECT THE AIRPORTS BETWEEN 08-10Z
WITH STRONG AND GUSTY WEST WINDS POSSIBLE. WEST WINDS WILL PREVAIL
BEHIND THE LINE FOR A FEW HOURS AND EVENTUALLY BECOME SOUTHWEST
DURING THE SUNDAY MORNING HOURS. SPEEDS WILL INCREASE IN THE
AFTERNOON TO 10-15 KTS WITH HIGHER GUSTS. MVFR CIGS WILL PREVAIL
UNTIL THE SQUALL LINE PASSES AND THEN CIGS WILL IMPROVE TO VFR
AND SHOULD BECOME MOSTLY CLEAR SUNDAY AFTERNOON.
