DISCUSSION
ISSUED AT 308 PM CST SUN JAN 11 2026
THROUGH MONDAY: LATEST SURFACE ANALYSIS HAD A DRY REINFORCING COLD
FRONT NEARLY ALONG INTERSTATE 20. SATELLITE IMAGERY/RAP ANALYSIS
SHOWED NORTHWEST FLOW ALOFT THAT IS PROGGED TO CONTINUE THROUGH
MONDAY. THIS WILL HELP THE COLD FRONT PUSH SOUTH OF OUR CWA BY THIS
EVENING. A >1034MB HIGH WILL CONTINUE BUILDING OVER OUR CWA FROM THE
NORTHWEST IN WAKE OF THE COLD FRONT. THIS WILL BRING IN A COOLER AND
EVEN DRIER AIRMASS TO OUR REGION. THE GUSTY NORTH WIND THIS
AFTERNOON WILL SUBSIDE BY THIS EVENING AND UNDER STRONG RADIATIONAL
COOLING TONIGHT TEMPERATURES WILL BOTTOM OUT IN THE MID 20S TO NEAR
30 DEGREES. MONDAY THE SURFACE HIGH WILL BECOME CENTERED OVER OUR
CWA AND WEAKEN RESULTING IN A MUCH LIGHTER WIND THAN TODAY.
TEMPERATURES WILL TOP OUT IN THE LOWER 50S WHICH IS SLIGHTLY COOLER
THAN NORMAL. /22/
MONDAY NIGHT THROUGH SATURDAY NIGHT: COOL AND DRY NORTHWEST
FLOW ALOFT WILL BE THE PRIMARY WEATHER INFLUENCE THIS WEEK, BUT
EXPECT A FEW TEMPERATURE SWINGS AS A COUPLE OF POLAR AIR MASSES WILL
BE POISED TO SURGE INTO THE AREA LATE THIS WEEK AND AGAIN NEXT
WEEKEND. ULTIMATELY, THE BULK OF GUIDANCE INDICATE A BRIEF WARM UP
FOR TUE-WED, FOLLOWED BY A MORE SIGNIFICANT SURGE OF COLD AIR FOR
WED NIGHT-THU NIGHT THAT SHOULD HAVE TEMPERATURES A GOOD BIT BELOW
CLIMATE NORMALS. ANOTHER BRIEF WARM UP SHOULD TAKE PLACE FRIDAY
AHEAD OF THE NEXT POLAR AIR SURGE OVER THE WEEKEND. GUIDANCE SHOWS A
GOOD BIT OF VARIABILITY WITH JUST HOW INTENSE THE COLD WILL BE, BUT
IT WILL BE SOMETHING TO KEEP AN EYE ON IN TERMS OF IMPACTS. AS HAS
BEEN DISCUSSED RECENTLY, WINTER WEATHER THREATS REMAIN LOW FOR THE
LONG RANGE FORECAST WITH THE BULK OF GUIDANCE NOT TIMING
MOISTURE/COLD WELL ENOUGH FOR ANY WINTRY PRECIP. /EC/
