CHANGES SINCE PREVIOUS FORECAST...
* A WINTER STORM WARNING IS NOW IN EFFECT FOR ALL COUNTIES IN THE
WARNING AREA.
WATER VAPOR IMAGERY THIS AFTERNOON DEPICTS A MID/UPPER JET MAX
SPANNING FROM THE HIGH PLAINS TOWARD THE OHIO RIVER VALLEY. AT THE
SURFACE, HIGH PRESSURE SLIDING SOUTHEAST TOWARD KENTUCKY HAS ALLOWED
FOR SOUTHERLY WINDS TO RESIDE OVER THE SOUTHERN HALF OF THE FORECAST
AREA TODAY, WHILE AREAS TO THE NORTH HAVE OBSERVED EASTERLY WINDS.
SNOW TONIGHT THRU TUESDAY EVENING...
TEMPERATURES LATER THIS EVENING INTO TONIGHT WILL QUICKLY TUMBLE
INTO THE LOWER TEENS AND SINGLE DIGITS AS THE WELL-ADVERTISED ARCTIC
AIRMASS PUSHES ITS WAY FROM NORTH TO SOUTH ACROSS THE REGION. THE
ASSOCIATED COLD FRONT WILL WORK IN CONCERT WITH WIDESPREAD SYNOPTIC
FORCING FOR ASCENT PROVIDED BY THE RIGHT ENTRANCE REGION OF THE
UPPER JET TO RESULT IN SNOW IMPACTING THE NORTHERN 3/4 OF THE STATE
TONIGHT INTO EARLY TUESDAY MORNING. AS THE BOUNDARY MOVES SOUTH,
COVERAGE WILL GRADUALLY EXPAND TO INCLUDE THE ENTIRE FORECAST AREA
AND A LARGE PORTION OF THE STATE ITSELF. LATEST HI-RESOLUTION
GUIDANCE HIGHLIGHTS THE CONTINUED POTENTIAL FOR EMBEDDED BANDS OF
LOW/MID-LEVEL FRONTOGENETICAL BANDS ALLOWING FOR SNOWFALL RATES
AROUND 1"/HR ESPECIALLY THROUGH THE MORNING AND AFTERNOON
TIMEFRAMES. THESE MODERATE TO HEAVY SNOWFALL RATES PAIRED WITH GUSTY
NORTHERLY WINDS WILL RESULT IN POOR VISIBILITIES, BLOWING AND
DRIFTING SNOW, AND OVERALL DANGEROUS TRAVEL CONDITIONS THROUGH
TUESDAY EVENING ACROSS MOST OF THE AREA.
PREVIOUS DISCUSSIONS HAVE HIGHLIGHTED THE VARIABILITY BETWEEN MODEL
RUNS REGARDING TOTAL SNOW ACCUMULATIONS THROUGH TUESDAY EVENING.
WHILE SOME MODELS (EURO/UKMET) HAVE TRENDED HIGHER TOTALS DOWN AND
FURTHER SOUTH, HIGH-RESOLUTION AND REGIONAL MODELS (NAM/HRRR/RAP,
ETC.) HAVE REMAINED RELATIVELY CONSISTENT IN THEIR DEPICTIONS OF
POTENTIAL FOR RELATIVELY HIGH AMOUNTS. AS SUCH, THE CURRENT
EXPECTATION IS FOR WIDESPREAD ACCUMULATIONS OF AT LEAST 4-6 INCHES
THROUGHOUT THE AREA, WITH THE POTENTIAL FOR UPWARDS OF 8+ INCHES IN
SOUTHEAST KANSAS. AS STATED BEFORE, EMBEDDED BANDS OF ENHANCED
SNOWFALL ARE LIKELY PER HI-RES SOLUTIONS, SO LOCALLY HIGHER TOTALS
ARE POSSIBLE AS WE HEAD INTO TUESDAY EVENING.
TEMPERATURES TONIGHT THRU FRIDAY MORNING...
IN ADDITION TO THE ARRIVAL OF SNOW TO THE AREA TONIGHT INTO TUESDAY,
THE ARCTIC AIRMASS WILL ALSO PROVIDE THE REGION WITH FRIGID
TEMPERATURES AND DANGEROUS WIND CHILLS. LATEST GUIDANCE CONTINUES TO
HOLD VALUES AROUND 20-30 DEGREES BELOW ZERO THROUGH AT LEAST
THURSDAY MORNING, WITH THE LOWEST VALUES EXPECTED IN CENTRAL KANSAS.
WIND CHILLS BACK OFF SLIGHTLY BY FRIDAY MORNING (AROUND -10) BEFORE
THE ARCTIC AIRMASS DEPARTS THE REGION AS WE HEAD INTO THE WEEKEND.
DAYTIME HIGHS IN THE SINGLE DIGITS AND LOW TEENS WILL PERSIST
THROUGH THURSDAY, THEN MODELS SUGGEST HIGHS IN THE 20S ON FRIDAY AND
40S ON SATURDAY. THESE WILL MORE THAN LIKELY BE SUBJECT TO CHANGE AS
SNOW COVER ON THE GROUND INHIBITS DAYTIME WARMING TOWARD THE END OF
THE WEEK.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1248 PM CST MON FEB 17 2025
MVFR CEILINGS ARE BEGINNING TO DROP SOUTH ACROSS CENTRAL KANSAS
EARLY THIS AFTERNOON BEHIND A STRONG ARCTIC COLD FRONT. THIS
FRONT WILL CONTINUE TO STEADILY MARCH SOUTH THIS AFTERNOON
BRINGING LOW CLOUDS AND BREEZY NORTHEAST WINDS TO ALL TERMINALS.
A STORM SYSTEM WILL APPROACH FROM THE WEST LATE TONIGHT INTO
EARLY TUESDAY MORNING BRINGING WIDESPREAD ACCUMULATING SNOWFALL
TO THE REGION. WITHIN THIS SNOW, CONDITIONS SHOULD GRADUALLY
DETERIORATE TO IFR OR LOWER FOR MANY LOCATIONS. ACCUMULATIONS OF
GENERALLY 4"-8" ARE EXPECTED HOWEVER A HEAVIER BAND OF SNOW NEAR
CNU MAY LEAD TO LOCALLY HEAVIER AMOUNTS.
