THE UPPER LEVEL PATTERN STILL DEPICTS A RIDGE INFLUENCING MUCH OF
THE SOUTHERN AND CENTRAL CONUS, WITH A SMALL LOW MOVING THROUGH
ONTARIO AND A LARGER LOW SPINNING OFF THE PACIFIC COAST. AT THE
SURFACE, AN AREA OF LOW PRESSURE IS NOTED IN MN WITH AN ASSOCIATED
COLD FRONT DRAPED ACROSS NE. THE LLJ IS BRINGING THE STRONGEST LIFT
AND WAA INTO SOUTHERN IA AND NORTHERN MO, WHICH IS WHERE THE MOST
WIDESPREAD THUNDERSTORMS HAVE BEEN THE LAST FEW HOURS. SO FAR OUR
AREA HAS ONLY BEEN CLIPPED BY AN ISOLATED SHOWER/WEAK STORM IN BROWN
COUNTY. THE PRIME AREA OF ISENTROPIC LIFT WILL CONTINUE TO PUSH
SOUTH THROUGH MO THIS MORNING, AND MAY EXTEND FAR ENOUGH WEST TO
IMPACT FAR EASTERN PARTS OF THE AREA FOR A BRIEF PERIOD AROUND 12-
13Z. THE FV3 HAS RAIN MISSING THE AREA ENTIRELY, BUT MOST OTHER CAMS
HAVE AT LEAST A FEW ISOLATED SHOWERS/STORMS IN OUR AREA FOR A FEW
HOURS THIS MORNING. THE WEAK FRONTAL BOUNDARY IS PROGGED TO MOVE
SOUTH THROUGHOUT THE DAY, BUT WILL DO LITTLE IN TERMS OF SENSIBLE
WEATHER CHANGES. TEMPERATURES STILL LOOK WARM WITH HIGHS IN THE 80S
FOR MOST, WITH THE UPPER RIDGE AXIS NEARBY.
A SUBTLE WAVE ROUNDING THE RIDGE LOOKS TO PASS NORTHWEST OF THE AREA
LATE TONIGHT INTO SATURDAY MORNING, BRINGING MID TO HIGH CLOUDS
DURING THAT TIME BUT KEEPING US OUT OF THE PATH OF ANY RAIN CHANCES.
FAR NORTHEAST KS MAY STAY IN THE 70S WHERE CLOUDS LINGER LONGER
WHILE MOST EVERYONE ELSE SEES HIGHS IN THE 80S ONCE AGAIN. SUNDAY IS
THE WARMEST DAY AHEAD, AS A SHORTWAVE ADVANCING ACROSS THE NORTHERN
ROCKIES INDUCES A LEE SFC TROUGH AND A TIGHT PRESSURE GRADIENT OVER
US. THIS WILL ENHANCE LOW-LEVEL SOUTHERLY FLOW AND HELP TO BOOST
TEMPERATURES TO THE 80S AREA-WIDE. A COLD FRONT IS EXPECTED TO MOVE
THROUGH THE AREA LATE SUNDAY NIGHT INTO MONDAY MORNING, BRINGING THE
NEXT BEST RAIN CHANCE (20-30%). MOST OF THIS LOOKS TO BE POST-
FRONTAL WITH LIMITED INSTABILITY TO WORK WITH, AND RAIN AMOUNTS LOOK
LIGHT.
FORECAST CONFIDENCE DWINDLES FOR MOST OF NEXT WEEK DUE TO LOW
PREDICTABILITY IN THE EXACT PLACEMENT IN EMBEDDED SHORTWAVES
ROUNDING THE UPPER RIDGE AS IT GETS PUSHED SOUTH. THE MOST RECENT
NBM HAS BACKED OFF SOMEWHAT ON POPS TUESDAY ONWARD, BUT TEMPERATURE
RANGES ARE STILL LARGE, INDICATIVE OF LOWER CONFIDENCE IN THE
FORECAST. THINK RAIN CHANCES, ALBEIT SMALL, ARE STILL A REASONABLE
POSSIBILITY UNTIL IT BECOMES CLEARER WHERE THOSE WAVES WILL TRAVEL.
FOR NOW, EXPECT A COOLDOWN MONDAY BEHIND THE FRONT WITH HIGHS IN THE
UPPER 60S TO LOW 70S, AND PERHAPS A SLIGHT WARMUP MID TO LATE WEEK
PENDING CLOUDS AND PRECIP.
AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
ISSUED AT 1220 PM CDT FRI OCT 10 2025
VFR CONDITIONS REMAIN IN PLACE THROUGH THIS EVENING AND PROBABLY
THROUGH THE ENTIRE PERIOD. COULD BE A WINDOW FOR GROUND FOG TO
FORM AROUND SUNRISE MAINLY AROUND KTOP. FOG POTENTIAL LOOKS TO
BE LOW CONFIDENCE OR IMPACT IF IT DOES FORM DUE TO HIGH LEVEL
CLOUDS BEGINNING TO OVERSPREAD THE AREA INTO THE OVERNIGHT
PERIOD. WINDS GRADUALLY VEER TO THE ESE INTO TOMORROW MORNING
BUT LIKELY REMAIN BELOW 10KTS THROUGH THE PERIOD.
TOP WATCHES/WARNINGS/ADVISORIES
