DISCUSSION
ISSUED AT 300 PM CST SAT DEC 13 2025
SNOW WAS STARTING TO TAPER OFF EARLY THIS AFTERNOON AS DRIER
AIR AND SURFACE HIGH PRESSURE CONTINUED TO WORK IN FROM THE
NORTH. MODEL SOUNDINGS SUGGEST WE COULD STILL SEE SOME FLURRIES
HEADING INTO EARLY EVENING WITH A LITTLE SATURATION IN THE
DENDRITIC GROWTH ZONE JUST ABOVE THE SURFACE, BUT ANY
ACCUMULATING SNOW SHOULD LARGELY BE DONE NOW. OTHERWISE, HIGH
PRESSURE WAS ALSO HELPING TO GRADUALLY CLEAR THE CLOUDS OUT WITH
WINDS BECOMING LIGHT. AS A RESULT, WE'RE STILL ON TRACK FOR
VERY COLD TEMPERATURES TONIGHT INTO SUNDAY, WITH LOWS RANGING
FROM AROUND -10 IN NORTHEAST NE AND WEST-CENTRAL IA TO AROUND 5
ACROSS PORTIONS OF SOUTHEAST NE. WHILE THE WINDS WILL BE LIGHT,
ANY SMALL PUFF OF WIND COULD LEAD TO WIND CHILLS APPROACHING 20
BELOW 0 IN THE COLDEST AREAS. THAT SAID, THINK THOSE READINGS
WILL BE FEW AND FAR BETWEEN, SO ELECTED TO HOLD OFF ON A COLD
WEATHER ADVISORY, BUT REGARDLESS, IT'S GOING TO BE COLD. A FEW
PIECES OF GUIDANCE DO HINT AT FOG DEVELOPMENT ACROSS NORTH-
CENTRAL IN NORTHEAST NE EARLY SUNDAY MORNING. IF IT DOES HAPPEN,
GIVEN HOW COLD IT'S GOING TO BE, COULD SEE SOME SLICK SPOTS
DEVELOP. HOWEVER, A VAST MAJORITY OF GUIDANCE KEEPS THE LOW
LEVELS DRY, SO WOULD ONLY GIVE IT A 10-20% CHANCE OF HAPPENING.
OTHERWISE, WINDS WILL BECOME SOUTHERLY ON THE BACK SIDE OF THE
DEPARTING HIGH DURING THE DAY SUNDAY, BUT WE'LL STILL REMAIN
COLD WITH TEMPERATURES TOPPING OUT IN THE TEENS TO MID 20S.
WE'LL START TO SEE A SIGNIFICANT WARMUP ON MONDAY AS UPPER
LEVEL RIDGING STARTS TO NUDGE IN FROM THE WEST. EXPECT HIGHS IN
THE MID 30S TO UPPER 40S FROM EAST TO WEST ACROSS THE AREA. THE
RIDGE WILL FLATTEN OUT AS WE GET TOWARD MID-WEEK, BUT THE
WARMING TREND WILL CONTINUE, AS WE SEE MID 40S TO MID 50S
TUESDAY AND WEDNESDAY, WITH AN OUTSIDE SHOT AT A FEW LOCATIONS
MAKING A RUN AT 60.
OUR NEXT SYSTEM OF INTEREST WILL ARRIVE WEDNESDAY INTO THURSDAY
AS A CUTOFF LOW MOVES ALONG THE ND/CANADA BORDER AND DRAGS A
WARM FRONT INTO THE AREA DURING THE DAY AND A COLD FRONT THROUGH
OVERNIGHT INTO EARLY THURSDAY. STILL SOME QUESTIONS ON EXACT
TIMING OF THE VARIOUS FEATURES AS WELL AS MOISTURE AVAILABILITY,
BUT TRENDS ARE TOWARD INCREASING PRECIP CHANCES IN AT LEAST
NORTHEAST NE (20% CHANCE). IF WE DO GET ANYTHING, CONSENSUS
WOULD SUGGEST WE STAY ABOVE FREEZING WHILE ANY PRECIP FALLS, SO
IT SHOULD ALL BE RAIN. BEHIND THE COLD FRONT, WE'LL SEE STRONG
WEST TO NORTHWEST WINDS ON THURSDAY. STILL SOME DETAILS TO BE
WORKED OUT THERE, BUT EPS GUIDANCE SUGGESTS AT LEAST A 60-90%
CHANCE OF SEEING 30 MPH GUSTS ACROSS THE AREA AND A 50% CHANCE
OF SEEING AT LEAST 40 MPH GUSTS, MAINLY NORTH OF I-80. DESPITE
THE FRONTAL PASSAGE, THE WARMER WEATHER LOOKS TO STICK AROUND TO
END THE WORK WEEK, WITH HIGHS REMAINING IN THE UPPER 30S AND
40S.
AVIATION /18Z TAFS THROUGH 18Z SUNDAY/
ISSUED AT 1114 AM CST SAT DEC 13 2025
MOSTLY MVFR CEILINGS ACROSS THE AREA WITH MVFR TO IFR VISIBILITY
WITH SNOW CONTINUING TO PUSH THROUGH. SNOW LOOKS TO COME TO AN
END BY MID AFTERNOON WITH PERHAPS A FEW FLURRIES LINGERING INTO
THIS EVENING. ADDITIONAL ACCUMULATION SHOULD BE NO MORE THAN A
HALF INCH. CEILINGS SHOULD SCATTER OUT SHORTLY THEREAFTER,
THOUGH A FEW PIECES OF GUIDANCE HINT AT SOME LINGERING MVFR TO
IFR CEILINGS, OR MAYBE EVEN SOME FOG IN NEAR AND WEST OF OFK
INTO EARLY SUNDAY. THERE IS ONLY ABOUT A 10-20% CHANCE OF
THIS HAPPENING, SO DID NOT INCLUDE MENTION AT THIS TIME.
OTHERWISE, NORTH WINDS WILL CONTINUE OVERNIGHT WITH SPEEDS
AROUND 10-12 KTS THIS AFTERNOON FALLING UNDER 10 KTS THIS
EVENING. WINDS THEN BECOME SOUTHEASTERLY SUNDAY MORNING, BUT
SHOULD REMAIN FAIRLY LIGHT THROUGH THE REMAINDER OF THE PERIOD.
