QUIET AND MILD CONDITIONS THIS AFTERNOON AS A COLD FRONT CURRENTLY
NEAR THE KS/NE BORDER SLOWS AS IT SHIFTS SOUTHWARD, BISECTING THE
CWA BY LATE AFTERNOON. NORTHEAST WINDS INCREASE ALONG/NORTH OF THE
BOUNDARY FROM 15-20 MPH, GUSTING TO 25 MPH. MID CLOUDS INCREASE THIS
AFTERNOON AS AN EMBEDDED UPPER TROUGH ROUNDS THE RIDGE TO THE WEST
BEFORE TRACKING SOUTHEAST THROUGH EASTERN NE AND NORTHERN MO
TONIGHT. LATEST SHORT TERM GUIDANCE IS CONSISTENT WITH THE NARROW
BAND OF FORCING STAYING NORTH COUPLED WITH THE LACK OF DEEP MOISTURE
IN NORTHEAST KANSAS. HAVE THEREFORE REDUCED POPS FOR MUCH OF THE
AREA, CONFINED MOSTLY TO THE HIGHWAY 36 CORRIDOR. TEMP PROFILES AFT
06Z TUESDAY SUGGEST THE POSSIBILITY FOR BRIEF LIGHT SNOW TO MIX IN,
HOWEVER NO ACCUMULATIONS OR IMPACTS EXPECTED.
UPPER PATTERN SHIFTS AS THE RIDGE BREAKS DOWN, ALLOWING FOR SEVERAL
WAVES TO TRAVERSE THE PLAINS FROM WEDNESDAY INTO THE WEEKEND.
INITIAL TIME PERIOD TO HIGHLIGHT IS WEDNESDAY EVENING INTO THURSDAY
AS A COLD FRONT ENTERS THE REGION. ENSEMBLE SPREAD IS HIGH DUE TO
TIMING OF THE WAVE WITH THE FRONT AND DEGREE OF MOISTURE AVAILABLE.
SPREAD OF QPF IN THE 25TH-75TH PERCENTILE IS IN UPWARDS OF AN INCH
WITH OVERALL LOW CONFIDENCE ON THE LOCATION OF THE LIKELY POPS IN
THE FORECAST.
WHILE A WASHOUT IS NOT ANTICIPATED FOR THE WEEKEND, THE STALLED
FRONT NEARBY COUPLED WITH SEVERAL PERTURBATIONS ARRIVING UPSTREAM
OF A SOUTHERN STREAM CLOSED LOW WARRANTS MODEST POPS FOR THE
ENHANCED ISENTROPIC LIFT. PWAT VALUES ARE NOT WELL ABOVE CLIMO
VALUES FOR THIS TIME OF YEAR TO SUGGEST A ELEVATED RISK FOR FLOODING
OR HEAVY RAINFALL. NEVERTHELESS, LOCALLY HEAVY RAINFALL IS POSSIBLE
FOR PORTIONS OF THE REGION BY THE WEEKEND. OVERALL SEVERE THREAT IS
LOW, BUT COULD SEE A FEW STRONGER STORMS DURING THIS PERIOD.
AVIATION /18Z TAFS THROUGH 18Z TUESDAY/
ISSUED AT 1152 AM CDT MON APR 6 2026
VFR TAFS ARE EXPECTED TO CONTINUE THROUGH THE PERIOD AT ALL
SITES. WINDS WILL REMAIN OUT OF THE NORTHEAST FOR MOST OF THE
PERIOD BEFORE SHIFTING OUT OF THE SOUTHEAST BY LATE TUESDAY
MORNING. SOME OCCASIONAL GUSTS TO 20-25 MPH MAY OCCUR IN THE
OVERNIGHT HOURS, ESPECIALLY AT KMHK, BUT OPTED TO KEEP OUT AT
THIS TIME.
TOP WATCHES/WARNINGS/ADVISORIES
