ISENTROPIC UPGLIDE IS AND WILL BE THE MAIN WEATHER PRODUCER FOR
THE ARK-LA-TEX OVER THE NEXT 24 HOURS. IN THE PROCESS OF THIS
ACTIVITY, SHALLOW COLD AIR WILL BOOST THE PROBABILITY OF FREEZING
RAIN NEAR THE OUACHITA MOUNTAINS, PROMPTING ISSUANCE OF THE WINTER
WEATHER ADVISORY. THERE IS SOME POTENTIAL FOR A TEMPORAL EXTENSION
OF THIS PRODUCT TEMPERATURE MAXIMUMS WILL NOT CLIMB MUCH INTO THE
40S BEFORE FALLING BACK INTO MINIMUMS IN THE 20S-30S AT THE
COLDEST ON MONDAY NIGHT BEFORE REBOUNDING BACK TO NEAR- NORMAL BY
MID- WEEK. LONG- RANGE GUIDANCE SHOWS THE WET PATTERN CONTINUING
WITH YET ANOTHER TROUGH TRAVERSING THE INTERMOUNTAIN WEST, EXITING
TO A CONFLUENCE OF PACIFIC MOISTURE FOR PRECIPITATION RETURNING
BY LATE WEDNESDAY THROUGH MOST OF THE REST OF THE WEEK. FRONTAL
PASSAGE BY SATURDAY WILL INTRODUCE THE NEXT REPRIEVE FROM RAINFALL
THROUGH THE NEXT WEEKEND. /16/

MOVE INTO AREA AIRSPACE AND WILL INCREASE IN COVERAGE THROUGHOUT
THE DAY. FLIGHT CATEGORIES HAVE DETERIORATED AS ANTICIPATED AND
FURTHER DETERIORATION TO MVFR LEVELS IS EXPECTED AS PRECIP IMPACTS

EXPECTED. THAT BEING SAID, KTXK AND KELD MAY SEE VERY BRIEF
FROZEN PRECIPITATION THIS MORNING. NORTHEAST WINDS WILL CONTINUE
