DISCUSSION
ISSUED AT 231 PM CDT TUE OCT 7 2025
THE SHORTWAVE TROUGH THAT BROUGHT YESTERDAY'S COLD FRONT IS MOVING
AWAY TO THE NORTHEAST, ALLOWING MORNING RAIN AND CLOUDS TO CLEAR
ACROSS OUR AREA. BEHIND THE FRONT, TEMPERATURES ARE STILL IN THE 60S
DESPITE PLENTY OF SUN, WITH NORTHERLY WINDS ADVECTING DRIER
DEWPOINTS SOUTHWARD. SURFACE RIDGING WILL STAY IN PLACE FOR THE NEXT
36 HOURS, KEEPING COOL TEMPERATURES AROUND. WITH CLEAR AND CALM
CONDITIONS, LOWS TOMORROW MORNING WILL FALL INTO THE LOW/MID 40S.
THIS MAY ALLOW FOR SOME AREAS OF FOG TO DEVELOP, MOST LIKELY IN THE
USUAL LOW-LYING AREAS OF NORTHEAST KANSAS. HIGH TEMPERATURES WARM A
BIT TOMORROW, BUT STILL STAY SLIGHTLY BELOW AVERAGE.
WE'LL WARM BACK UP THURSDAY INTO THE WEEKEND AS UPPER RIDGING AGAIN
TAKES HOLD ACROSS THE MIDDLE PART OF THE COUNTRY. A RATHER AMPLIFIED
PATTERN WITH UPPER LOWS OVER BOTH COASTS WILL PREVENT THE RIDGE AXIS
FROM MOVING TOO MUCH UNTIL LATER IN THE WEEKEND. SO WE'LL SEE A
RETURN TO TEMPERATURES IN THE 80S FRIDAY THROUGH SUNDAY, WITH
OVERNIGHT LOWS ALSO 5-10 DEGREES ABOVE AVERAGE. CAN'T COMPLETELY
RULE OUT A FEW SHOWERS THURSDAY MORNING AND AGAIN FRIDAY MORNING
WITH A PAIR OF WEAK MID-LEVEL PERTURBATIONS. HOWEVER MOISTURE AND
FORCING FOR ASCENT WILL BE LIMITED, KEEPING ANY RAIN CHANCES AROUND
OR BELOW 15 PERCENT. BY EARLY NEXT WEEK, WE MAY BEGIN TO SEE SOME
SLIGHTLY BETTER RAIN CHANCES AS THE RIDGE AXIS SHIFTS TO OUR EAST
AND MID-LEVEL FLOW BECOMES SOUTHWESTERLY AHEAD OF THE NEXT TROUGH.
HOWEVER THERE IS STILL A LOT OF UNCERTAINTY WITH THE OVERALL
EVOLUTION OF INDIVIDUAL SHORTWAVES BY THIS POINT, KEEPING CONFIDENCE
LOW ON THE DETAILS.
AVIATION /06Z TAFS THROUGH 06Z THURSDAY/
ISSUED AT 1246 AM CDT WED OCT 8 2025
WITH CLEAR SKIES AND LIGHT/CALM WINDS IN PLACE, SOME SHALLOW
GROUND FOG MAY DEVELOP AROUND SUNRISE. TOP HAS THE BEST CHANCE
OF BEING IMPACTED; FORECAST SOUNDINGS SHOW THE SURFACE TO BE A
BIT DRIER AT MHK, BUT GIVEN THE SETUP WILL MAINTAIN MENTION IN
TEMPO GROUP FOR NOW. OTHERWISE, VFR PREVAILS WITH WINDS PICKING
UP OUT OF THE SE IN THE MORNING, BUT STILL UNDER 10 KTS THROUGH
THE PERIOD.
TOP WATCHES/WARNINGS/ADVISORIES
NONE.
