UPDATE
ISSUED 800 PM CDT TUE OCT 13 2026
THE OVERALL TRAJECTORY OF EVENING STORM ACTIVITY HAS SHIFTED TO
MOSTLY IMPACTING THE SOUTHERN PORTION OF THE CWA. AT TIMES WE
HAVE SEEN SOME GROWTH WHERE HAIL BECAME A MILD CONCERN BUT STORM
GROWTH NEVER ENDED UP BECOMING SIGNIFICANT ENOUGH TO WORRY ABOUT
LARGER HAIL AND GIVEN INSTABILITY GRADUALLY DECREASING THIS
EVENING WE DO NOT ANTICIPATE STORMS GETTING MUCH STRONG AS THEY
TRACK ACROSS SOUTHEAST WI OVER THE NEXT FEW HOURS. SOME
LINGERING SHOWERS AFTER STORMS PASS BUT WILL GRADUALLY CLEAR OUT
WITH LOW CLOUDS COMING IN BEHIND IT.

SHORT TERM
ISSUED 101 PM CDT TUE OCT 13 2026
THIS AFTERNOON THROUGH WEDNESDAY NIGHT:
AN AREA OF WARM AIR ADVECTION ALOFT ALONG WITH A WEAK PUSH OF
HIGHER MOISTURE IS EXPECTED TO MOVE THROUGH THIS EVENING.
THIS FORCING NEAR THE NEBRASKA/IOWA BORDER EARLY THIS AFTERNOON
IS PRODUCING SOME INCREASED CLOUDINESS AND OCCASIONAL SHOWERS.
THE DEEPER MOISTURE AND BETTER FORCING WILL REMAIN WITHIN THE
FRONTAL REGION TO THE SOUTH OF WISCONSIN, BUT COULD SEE ENOUGH
FORCING/MOISTURE MOVING THROUGH SOUTHERN WISCONSIN LATER FOR
SCATTERED SHOWERS. A RUMBLE OR TWO OF THUNDER WILL BE POSSIBLE,
AS MODELS ARE SHOWING A LITTLE INSTABILITY SNEAKING NORTH OF THE
WI/IL BORDER. ANY SHOWERS THAT DO DEVELOP SHOULD DEPART TO THE
EAST BY AROUND MIDNIGHT TONIGHT, WITH DRY WEATHER THEN EXPECTED
OVERNIGHT.
DRY WEATHER IS EXPECTED WEDNESDAY AS HIGH PRESSURE MOVES THROUGH
THE REGION. TEMPERATURES WILL BE COOLER TOMORROW UNDER THE HIGH,
BUT STILL NEAR OR EVEN A COUPLE DEGREES ABOVE NORMAL FOR MID-
OCTOBER.

LONG TERM
ISSUED 101 PM CDT TUE OCT 13 2026
THURSDAY THROUGH TUESDAY:
WIDESPREAD SHOWERS ARE EXPECTED ON THURSDAY, DUE TO INCREASING
MOISTURE AND WARM AIR ADVECTION AHEAD OF A STRONG APPROACHING
TROUGH OF LOW PRESSURE. THOUGH CONFIDENCE IS HIGH IN PRECIP
CHANCES OVERALL, THERE ARE INDICATIONS THAT THE HIGHER RAINFALL
TOTALS MAY BE NORTH NEAR TOWARD THE BETTER UPPER TROUGH FORCING
AND ALSO SOUTH NEAR THE SURFACE LOW TRACK. OVERALL THOUGH, THE
FORCING AND MOISTURE ARE ENOUGH TO MAINTAIN HIGH PRECIP CHANCES
FOR THE FORECAST AREA.
THE MAIN COLD FRONT WITH THE LATE WEEK SYSTEM IS EXPECTED TO
MOVE THROUGH THURSDAY EVENING, WITH THE TROUGH PASSAGE LATE
THURSDAY NIGHT INTO EARLY FRIDAY MORNING. A FEW SHOWERS MAY
LINGER WITH THE TROUGH PASSAGE LATE THU INTO EARLY FRI, BUT
PRECIP CHANCES WILL BE MUCH LOWER BEHIND THE COLD FRONT AS A
MUCH DRIER AIRMASS MOVES IN. MUCH COOLER CONDITIONS ARE ALSO
EXPECTED BEHIND THIS SYSTEM, WITH HIGHS ONLY IN THE 50S FRIDAY
AND SATURDAY. IT STILL LOOKS LIKE THERE IS THE POTENTIAL FOR THE
FIRST WIDESPREAD FROST OF THE SEASON FRIDAY NIGHT INTO SATURDAY
MORNING UNDER HIGH PRESSURE.
SURFACE HIGH PRESSURE IS EXPECTED TO BE IN PLACE ACROSS THE
REGION MUCH OF THE TIME OVER THE WEEKEND INTO EARLY NEXT WEEK,
WITH DRY WEATHER LIKELY THROUGH THIS PERIOD. SOUTHERLY WINDS
WILL DEVELOP ON THE BACK SIDE OF THE HIGH BY EARLY NEXT WEEK,
WITH TEMPERATURES RETURNING TO AT LEAST NORMAL, IF NOT SEVERAL
DEGREES ABOVE NORMAL BY TUESDAY.

NORTHWEST WINDS THIS AFTERNOON WILL GRADUALLY BECOME NORTHERLY
MOST PLACES THIS EVENING INTO TONIGHT BETWEEN DEPARTING LOW
PRESSURE OVER THE EASTERN GREAT LAKES AND AN APPROACHING HIGH
OF 30.3 INCHES. WINDS WILL INCREASE TO 10 TO 20 KNOTS BY THE
AFTERNOON TOMORROW, ESPECIALLY ACROSS THE SOUTHERN HALF OF THE
LAKE. WINDS WILL THEN BECOME EASTERLY WEDNESDAY NIGHT INTO
THURSDAY AS THE HIGH HEADS EASTWARD, WITH THE STRONGER WINDS
REMAINING OVER THE SOUTHERN HALF OF THE LAKE. A SMALL CRAFT
ADVISORY MAY EVENTUALLY BE NEEDED FOR LATER WEDNESDAY INTO
THURSDAY DUE TO BUILDING WAVES UNDER THE PERSISTENT ONSHORE
FLOW.
A STRONG SYSTEM WILL MOVE THROUGH LATE IN THE WEEK, BRINGING
INCREASING NORTHWEST WINDS THURSDAY NIGHT INTO FRIDAY BEHIND
THE LOW AND ASSOCIATED COLD FRONT. THERE IS INCREASING
CONFIDENCE IN A PERIOD OF GALES, WITH A FEW GUSTS POTENTIALLY
APPROACHING STORM FORCE.
