DISCUSSION
ISSUED AT 355 AM CST FRI DEC 26 2025
AN UNUSUALLY WARM WEATHER PATTERN WITH STRONG CENTRAL CONUS
RIDGING WILL CONTINUE THROUGH THIS WEEKEND. ASIDE FROM NEAR
RECORD WARMTH, WE WILL CONTINUE TO EXPERIENCE LATE NIGHT TO EARLY
MORNING DENSE FOG EVENTS, MAINLY OVER SOUTHERN AND EASTERN
PORTIONS OF THE AREA WHERE WIDESPREAD DENSE FOG IS CURRENTLY BEING
OBSERVED.
AFTER A LONG STRETCH OF WELL ABOVE NORMAL WARMTH, THERE WILL BE A
SHARP CHANGE TO MUCH COLDER TEMPERATURES EARLY NEXT WEEK AS A
STRONG COLD FRONT BRINGS IN A RUSH OF COLD POLAR AIR. THE BULK OF
GUIDANCE HAVE LOCKED IN ON A LATE SUNDAY NIGHT TO EARLY MONDAY
MORNING FRONTAL PASSAGE, MEANING THAT HIGH TEMPERATURES COULD BE
EARLY IN THE DAY FOR MUCH OF THE AREA GIVEN THE STRONG COLD
ADVECTION. RAINFALL WITH THE FRONT WILL BE LIGHT AND GENERALLY
LESS THAN A QUARTER OF AN INCH.
FOLLOWING THE FRONT, BRISK NORTHWEST/NORTHERLY WINDS MAY BE
STRONG ENOUGH TO REQUIRE FORMAL MESSAGING IN THE HWO GRAPHICS. THE
THERMAL TROUGH AND ASSOCIATED COLD SURFACE HIGH WILL SHIFT SLOWLY
ACROSS THE AREA THROUGH MID WEEK BRINGING A FEW NIGHTS OF LONG
DURATION FREEZES, BUT DANGEROUS COLD IMPACTS ARE NOT EXPECTED.
