SCATTERED SHOWERS AND FEW EMBEDDED THUNDERSTORMS CONTINUE TO MOVE
ACROSS NORTH-CENTRAL AND FAR NORTHEASTERN KANSAS THIS MORNING
BRINGING BENEFICIAL RAINFALL TO THE REGION. THIS IS ALL IN RESPONSE
TO A WEAK MID-LEVEL WAVE AND SURFACE TROUGH THAT IS CURRENTLY
TRACKING ACROSS EASTERN KANSAS WITH ADDITIONAL HELP FROM THE
PROXIMITY OF THE RIGHT ENTRANCE REGION OF THE UPPER LEVEL JET AND
LOW LEVEL WAA WITHIN A 25-30 KNOT LLJ. THROUGH THE REMAINDER OF THE
MORNING AND AFTERNOON, SCATTERED SHOWERS AND SOME ISOLATED
THUNDERSTORMS WILL CONTINUE ACROSS EASTERN KANSAS, WITH CHANCES
SLOWLY SPREADING INTO EAST-CENTRAL KANSAS AS THE SURFACE TROUGH
TRACKS SOUTHEAST. CAMS DEPICT A SLIGHT LULL IN COVERAGE BY THE
AFTERNOON AS INCREASING ML SUBSIDENCE AND SOME DRY AIR MIXING IN
BUILD IN FROM THE SOUTHWEST. TEMPERATURES TODAY WILL REFLECT THE
PRECIPITATION AND CAA FROM THE NORTH AS AREAS ACROSS NORTHERN AND
CENTRAL KANSAS TOP OUT IN THE 60S AND LOW 70S. AREAS ALONG AND SOUTH
OF I-35 WILL SEE THE LINGERING SOUTHERLY FLOW AND LACK OF
PRECIPITATION KEEP TEMPERATURES TOPPING OUT IN THE LOW TO MID 80S
ONCE AGAIN.
BY THIS EVENING, LOW LEVEL CONVERGENCE WITHIN THE 850-
700 MB LAYERS INCREASES AS SOME MID-LEVEL VORTICITY LOBES ADVECT
ACROSS KANSAS AND HELP TO RETURN WIDESPREAD PRECIPITATION CHANCES TO
EASTERN KANSAS. APPRECIABLE INSTABILITY SEEMS TO STAY SOUTH OF THE
AREA SO EXPECTING MOSTLY RAIN SHOWERS, BUT A FEW RUMBLES OF THUNDER
COULD BE REALIZED WITH TALLER UPDRAFTS MONDAY NIGHT AND EARLY
TUESDAY MORNING. ENSEMBLE GUIDANCE SHOWS ADDITIONAL ACCUMULATIONS
TONIGHT AROUND 0.25"-0.75". FORCING COMES TO AN END AROUND SUNRISE
TUESDAY MORNING WITH MID-LEVEL SUBSIDENCE OVERSPREADING EASTERN
KANSAS FOR THE REMAINDER OF THE MORNING. A 1028MB SURFACE HIGH
ADVECTS IN FROM THE NORTH THROUGH THE DAY, SLOWLY BRINING IN CLEARER
SKIES FROM THE NORTH. EXPECT HIGH TEMPERATURES TO TOP OUT IN THE MID
TO UPPER 60S. SIMILAR CONDITIONS WILL BE EXPECTED THROUGH THE DAY
WEDNESDAY WITH MOSTLY CLEAR SKIES AND TEMPS IN THE UPPER 60S AND LOW
70S.
THE REMAINDER OF THE WEEK WILL SEE TEMPERATURES SLOWLY WARMING BACK
INTO THE LOW 80S WITH SOME SMALL CHANCES FOR LIGHT RAIN THURSDAY
MORNING (20%). LONG RANGE GUIDANCE BEGINS TO HINT AT A LARGE TROUGH
ENTERING THE CENTRAL US BY SUNDAY/MONDAY THAT COULD BRING OUR NEXT
CHANCE OF WIDESPREAD PRECIPITATION AND PERHAPS ANOTHER AIRMASS
CHANGE.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
ISSUED AT 626 AM CDT MON OCT 6 2025
ONLY SLIGHT CHANGES TO TIMING OF TAFS FOR PRECIPITATION THIS
MORNING AND EVENING. MAIN CHALLENGE WILL BE THE OVERALL TIMING
OF MVFR AND IFR CIGS LATER IN THE TAF. PERIODS OF HEAVIER RAIN
AND STORMS MAY BRING DOWN CEILINGS QUICKER. STILL EXPECTING A
A LULL IN PRECIPITATION DURING THE AFTERNOON, BUT STILL COULD
SEE SOME ISOLATED TO SCATTERED SHOWERS. ADDED A PREVAILING
PRECIPITATION GROUP FOR ALL SITES TONIGHT THROUGH THE END OF THE
TAF FOR A SECOND WIDESPREAD ROUND OF SHOWERS, POSSIBLY SOME
RUMBLES OF THUNDER AS WELL.
TOP WATCHES/WARNINGS/ADVISORIES
NONE.
