AN AREA OF SHOWERS AND THUNDERSTORMS STRETCHES FROM SOUTHEAST
SOUTH DAKOTA SOUTHEASTWARD INTO NORTHWEST ILLINOIS EARLY THIS

IMPINGING ON A ELEVATED WARM FRONT DRAPED ACROSS THE AREA. THE
LOW LEVEL JET WILL VEER INTO EASTERN IOWA AND NORTHWEST
ILLINOIS THROUGH 12 UTC FRIDAY WITH POPS CONTINUING THROUGH LATE
MORNING ON FRIDAY. CHANCES FOR SHOWERS AND STORMS WERE EXTENDED
SOUTHWARD THIS MORNING FROM SOUTHEAST IOWA INTO NORTHEAST
MISSOURI AND WEST CENTRAL ILLINOIS TO ACCOUNT FOR A MORE
SOUTHERLY SHIFT BASED ON RADAR TRENDS.
SHOWERS AND STORMS ARE EXPECTED TO SHIFT TO THE NORTHEAST OF THE
AREA BY 18 UTC FRIDAY WITH LINGERING CLOUDS ACROSS THE AREA AS
THE SURFACE WARM FRONTS LIFTS NORTHWARD THROUGH FRIDAY NIGHT.

THERE HAS BEEN LITTLE CHANGE IN THE FORECAST FOR THIS WEEKEND
INTO NEXT WEEK FROM THE PREVIOUS FORECAST. PLEASE SEE THE
PREVIOUS FORECAST DISCUSSION BELOW.
THIS WEEKEND...
A BEAUTIFUL WEEKEND IS AHEAD OF US. WARM FRONT WILL HAVE FULLY MOVED
NORTHEAST AND OUT OF THE AREA, LEAVING US UNDER DECENT WARM
ADVECTION THROUGH THE WEEKEND. AS SUCH, TEMPERATURES ARE EXPECTED TO
INCREASE WELL ABOVE SEASONAL NORMALS, ESPECIALLY SATURDAY WITH THE
STRONGEST WARM ADVECTION. HOWEVER CLOUD COVER FROM THE REMNANTS
OF ISAIAS WILL HELP KEEP TEMPERATURES FROM REACHING THROUGH FULL
POTENTIAL ON SATURDAY. WIDESPREAD TEMPERATURES IN THE LOW 80S
ARE EXPECTED SATURDAY, WITH MID- UPPER 70S SUNDAY. MOSTLY CLEAR
CONDITIONS WILL PREVAIL ON SUNDAY AS CLOUDS ASSOCIATED WITH THE
REMNANTS OF ISAIAS SHIFT TO THE EAST.
NEXT WEEK...
ZONAL FLOW WILL START THE NEW WORK WEEK, WITH LLVL FLOW INCREASING
OUT OF THE SOUTHWEST AHEAD OF A PASSING WEAK SHORTWAVE. MONDAY WILL
REMAIN DRY AND UNSEASONABLY MILD, WITH THE WAVE AND ASSOCIATED COLD
FRONT PASSING THROUGH MONDAY NIGHT INTO TUESDAY. MOISTURE WILL
REMAIN LIMITED AHEAD OF THE FRONT, WHICH SHOULD LIMIT
PRECIPITATION CHANCES FOR MOST (<15% CHANCES). THUS, A LARGELY
DRY FORECAST. AFTER THAT WAVE, WE WILL SEE BRIEF RIDGING PRIOR
TO A STRONG WAVE DEEPENING OVER THE ROCKIES. AS THIS DEEPENS,
SOUTHWEST FLOW WILL SET UP OVER THE CENTRAL CONUS, SHUNTING THE
RIDGE EAST WEDNESDAY. WARM ADVECTION WILL INCREASE OVERHEAD
THROUGH MIDWEEK, WITH SHORTWAVES PASSING THROUGH AHEAD OF THIS
DEEP WAVE. THUS, A MORE ACTIVE PATTERN WILL TAKE SHAPE AND
CHANCES FOR SHOWERS/STORMS WILL BE ON THE RISE MIDWEEK AND
BEYOND. IT IS TOO SOON TO DETERMINE THE THREAT OF STRONG/SEVERE
STORMS, ALONG WITH HEAVY RAIN POTENTIAL.
AVIATION /06Z TAFS THROUGH 06Z SATURDAY/
ISSUED AT 1232 AM CDT FRI OCT 9 2026
A WEAK DISTURBANCE IS MOVING ACROSS THE AREA LATE TONIGHT INTO

WHERE PROB30 GROUPS WERE USED. USED TEMPO GROUPS AT KCID AND

STRONGEST SHOWERS AND STORMS. CONFIDENCE IS LOWER THAT
THUNDERSTORMS WILL DIRECTLY IMPACT TAF SITES TONIGHT.
