ANOTHER QUIET AND CHILLY AFTERNOON IS UNDERWAY TODAY AS SURFACE
RIDGING SETTLES IN FROM THE NORTH. OTHER THAN SOME HIGH CLOUD COVER
MOVING IN FROM THE WEST, AMPLE SOLAR INSOLATION HAS PUSHED
TEMPERATURES INTO THE MID TO UPPER 20S ACROSS THE AREA. SAFE TO
EXPECT TEMPERATURES TO WARM A FEW DEGREES FURTHER THIS AFTERNOON
WITH SOME ACROSS SOUTHERN AREAS OF THE CWA TOPPING OUT AROUND
FREEZING. THE 'WARM' WEATHER CONTINUES INTO WEDNESDAY AS WEAK LOBES
OF VORTICITY ADVECT OVER THE CENTRAL ROCKIES, DEEPENING A LEE
CYCLONE OVER EASTERN COLORADO. PRESSURE GRADIENTS GRADUALLY TIGHTEN
IN RESPONSE DURING THE DAY WEDNESDAY, RETURNING WINDS BACK TO THE
SOUTHWEST AND PROMOTING MODEST WAA BY THE AFTERNOON. AFTERNOON HIGH
TEMPERATURES WEDNESDAY UNDER THE WAA REGIME AND AMPLE SUNSHINE
SHOULD TOP OUT IN THE MID TO UPPER 30S, POSSIBLY SOME LOW 40S ACROSS
NORTH-CENTRAL KS.
THE WARMER AIR DOES NOT LAST LONG AS THE LEE CYCLONE THAT HAS
DEEPENED ACROSS EASTERN COLORADO EJECTS SOUTHEAST INTO THE PANHANDLE
OF OKLAHOMA IN RESPONSE TO A COMPACT SHORTWAVE PUSHING INTO THE
CENTRAL ROCKIES. COLD AIR FILTERS IN ON THE NORTH SIDE OF THIS
SURFACE LOW THROUGH THE DAY THURSDAY, DROPPING HIGH TEMPERATURES
BACK INTO THE 20S. SOME WEAK LOW-LEVEL LIFT MAY BECOME REALIZED AS
THE 850MB LOW PASSES THROUGH CENTRAL KS THURSDAY MORNING THAT COULD
SQUEEZE OUT SOME FLURRIES/SNOW, BUT WITH FORECAST SOUNDINGS
DEPICTING VERY DRY 850-700MB AIR, OPTED TO KEEP POPS LOW. PROFILES
DO NOT SATURATE IN THE LOW TO MID LEVELS UNTIL LATER THURSDAY
AFTERNOON AND INTO FRIDAY MORNING AS A SECONDARY WAVE IN THE
NORTHWESTERLY FLOW EJECTS INTO THE CENTRAL PLAINS. THE PASSAGE OF
THE SECOND WAVE MAY PROVIDE ENOUGH LIFT TO SQUEEZE OUT SOME LIGHT
SNOW SHOWERS ACROSS FAR NORTHERN KANSAS, BUT OVERALL CONFIDENCE
REMAINS LOW IN ANYTHING WIDESPREAD AT THIS TIME, THUS, CONTINUED WITH
SMALL AREA OF 15-25% POPS THURSDAY NIGHT INTO FRIDAY MORNING.
CAA CONTINUES FOR FRIDAY AND SATURDAY AS HIGHS TOP OUT IN THE UPPER
TEENS BOTH AFTERNOON WITH LOWS SATURDAY MORNING DROPPING BACK BELOW
0 DEGREES. WINDCHILLS SATURDAY MORNING MAY APPROACH -10 TO -15
DEGREES SO WILL NEED TO MONITOR FOR THE NEED OF ANY COLD WEATHER
ADVISORY HEADLINES. ANOTHER WAVE PASSES OVER THE REGION SATURDAY
NIGHT THAT COULD AGAIN YIELD SOME SNOW SHOWERS ACROSS THE AREA. POPS
AT THIS TIME REMAIN IN THE 20-30% RANGE AS LONG RANGE ENSEMBLE
GUIDANCE DEPICTS A 30-50% CHANCE OF NORTHEAST KANSAS SEEING
MEASURABLE SNOW.
AVIATION /00Z TAFS THROUGH 00Z THURSDAY/
ISSUED AT 442 PM CST TUE JAN 27 2026
DRY AIR WITH THE SURFACE RIDGE AND DEWPOINTS HOLDING IN THE
SINGLE DIGITS INDICATIVE OF LITTLE SNOW MELT SUPPORT VFR
CONDITIONS PERSISTING. FORECAST SOUNDINGS ALSO SHOW BOUNDARY
LAYER MOISTURE REMAINING VERY SHALLOW AND FAILING TO SATURATE.

FORECAST.
