SHORTWAVE TROUGH IS TRAVERSING OUT OF THE ROCKIES INTO KS WITH ITS
ASSOCIATED 850MB AND SFC LOWS SITUATED NEARBY IN THE TX/OK PANHANDLE
REGION EARLY THIS MORNING. THIS LOW PRESSURE WILL TREK SOUTH-
SOUTHEASTWARD ACROSS OK TODAY, BRINGING NNE WINDS AND BUILDING CAA
INTO THE AREA. THIS WILL LIMIT HIGHS TO THE 20S THIS AFTERNOON,
ENDING THE BRIEF WARM-UP THIS WEEK. IN TERMS OF SNOW CHANCES, THE
NAM NEST IS BY FAR THE MOST ROBUST OF ALL THE SHORT-TERM GUIDANCE
WITH ITS COVERAGE AND BRINGING LIGHT SNOWFALL INTO NORTHERN KS OUT
OF NE THIS MORNING INTO THE EARLY AFTERNOON. HOWEVER, EVEN THAT HAS
BACKED OFF WITH ITS 06Z RUN COMPARED TO ITS 00Z OUTPUT. THE OTHER
CAMS VARY A BIT IN THEIR COVERAGE AND SOUTHERN EXTENT, BUT GENERALLY
KEEP MOST SNOW BANDS NORTH OF THE KS/NE BORDER. OVERALL,
FRONTOGENESIS LOOKS RATHER WEAK AND SOUNDINGS DON'T LOOK ANY MORE
IMPRESSIVE IN TERMS OF LIFT WITHIN THE MID-LEVEL MOISTURE. LIFT
MIGHT BE A LITTLE BETTER IN SOUTHERN PORTIONS OF OUR AREA CLOSER TO
THE LOW, BUT THE LOW-LEVEL AIR IS DRIER THERE. PERHAPS THERE COULD
BE JUST ENOUGH TO SQUEEZE OUT SOME FLURRIES, BUT IT WOULD SEEM MUCH
MORE THAN THAT WOULD BE HARD TO COME BY. THERE IS ANOTHER SECONDARY
VORT MAX THAT COMES OUT OF THE ROCKIES INTO OK THIS EVENING, AND
ALTHOUGH SOUTHERN PORTIONS OF THE AREA MIGHT SEE SOME IMPROVEMENT IN
MOISTURE QUALITY BASED ON SOUNDINGS, THE LIFT DOESN'T LOOK MUCH
BETTER THAN TODAY. AS SUCH, HAVE KEPT POPS LOW AND FOCUSED ON NORTH
CENTRAL KS TONIGHT. SIMILAR TREND CONTINUES THROUGH THE DAY FRIDAY
AS LIFT AND MOISTURE DON'T LOOK TO CHANGE MUCH. HREF SNOW PROBS
INDICATE A 50% OR LESS CHANCE OF MEASURABLE SNOW THROUGH FRIDAY
EVENING, AND MOST OF THAT IS CONFINED TO NORTHERN OR NORTH CENTRAL
KS. OVERALL WOULD NOT EXPECT MUCH IMPACT FROM ANY SNOW THAT FALLS.
WE DO SEE STRENGTHENED CAA FRIDAY INTO SATURDAY MORNING AS A MORE
NOTABLE SHORTWAVE DIVES SOUTH THROUGH THE MIDWEST. THIS BRINGS HIGHS
DOWN TO THE TEENS TO LOW 20S BOTH DAYS, AND SATURDAY MORNING LOWS
BETWEEN 0 AND -5. EVEN WITH THE SFC RIDGE FOLLOWING THE UPPER WAVE
AND LIGHT WINDS, THERE COULD STILL BE JUST ENOUGH WIND TO BRING WIND
CHILLS TO BORDERLINE ADVISORY CRITERIA. WILL CONTINUE TO MONITOR
THAT POTENTIAL, ALTHOUGH LREF PROBS FOR WIND CHILLS AS LOW AS -15
HAVE LOWERED SOME.
ANOTHER WEAK SHORTWAVE COMES NEAR THE AREA SATURDAY NIGHT INTO EARLY
SUNDAY, ROUNDING THE UPPER RIDGE TO OUR WEST. THERE ARE STILL SOME
DIFFERENCES IN HOW FAR SOUTH ANY SNOW WOULD BE, WITH THE EURO AND
CANADIAN MOST FAVORING NORTHERN KS WHILE THE GFS AND NAM KEEP THE
SYSTEM FAR ENOUGH NORTH. ENSEMBLE DATA SUGGEST A 20-40% CHANCE OF
MEASURABLE SNOW DURING THIS TIME PERIOD, SO SIMILAR POPS FROM THE
NBM SEEM REASONABLE.
THE UPPER RIDGE LOOKS TO DAMPEN SOME INTO EARLY NEXT WEEK, BUT THE
INCREASING MID-LEVEL HEIGHTS STILL FAVOR A WARMING TREND DURING THAT
TIME. PRECIP CHANCES RETURN TUESDAY INTO EARLY WEDNESDAY AS A
PACIFIC TROUGH ENTERS THE REGION, BUT IT MAY NOT BECOME STRONG
ENOUGH TO PROVIDE ENOUGH FORCING UNTIL IT MOVES FURTHER EAST. GIVEN
THE UNCERTAINTIES, POPS ARE LIMITED TO 20-40%. ALSO GIVEN THE
FORECAST TEMPERATURES IT SHOULD BE NOTED THAT IF PRECIP OCCURS, IT
COULD START AS RAIN OR A RAIN/SNOW MIX BEFORE TRANSITIONING TO LIGHT
SNOW.
AVIATION /12Z TAFS THROUGH 12Z FRIDAY/
ISSUED AT 534 AM CST THU JAN 29 2026
VFR CONDITIONS ARE FORECAST. WINDS INCREASE OUT OF THE NORTHEAST
TODAY, LOOKING TO REACH AROUND OR ABOVE 10 KTS FOR AT LEAST PART
OF THIS MORNING AND AFTERNOON BEFORE BECOMING LIGHTER LATER THIS
AFTERNOON. FLURRIES HAVE A LOW CHANCE OF IMPACTING TERMINALS, SO
WILL LEAVE OUT ANY -SN MENTION. WINDS MAY TURN CALM OVERNIGHT
AS A SFC HIGH MOVES IN, SO WILL NEED TO WATCH FOR ANY FOG OR
STRATUS. AT THIS TIME, MVFR CIGS MAY MOVE IN AT THE VERY END OF
THE PERIOD, BUT WILL HOLD OFF FOR NOW UNTIL CONFIDENCE
INCREASES.
TOP WATCHES/WARNINGS/ADVISORIES
NONE.
