SHORT TERM
ISSUED 1158 PM CDT THU OCT 8 2026
TODAY THROUGH FRIDAY NIGHT:
AN AREA OF MIDDLE TO HIGH CLOUDS WILL CONTINUE TO PUSH
SOUTHEAST INTO THE AREA OVERNIGHT. MOST OF THE SHOWERS AND
STORMS OVER IOWA SHOULD REMAIN TO THE SOUTHWEST OF THE AREA AS
WELL OVERNIGHT. LOWS TONIGHT SHOULD DROP INTO THE MIDDLE 40S
NORTH AND UPPER 40S SOUTH.
MODELS CONTINUE TO SHOW AN AREA OF FOCUSED WARM AIR ADVECTION
WITH THE NOSE OF THE LOW LEVEL JET MOVING ACROSS FAR SOUTHERN
WISCONSIN AND NORTHERN ILLINOIS MAINLY LATER FRIDAY MORNING INTO
THE AFTERNOON. THIS SHOULD COMBINE WITH SOME MOISTURE IN THE
LOW TO MIDDLE LEVELS PER FORECAST SOUNDINGS TO BRING CHANCES (20
TO 60 PERCENT) FOR SHOWERS, HIGHEST ACROSS AREAS NEAR THE
ILLINOIS BORDER. A FEW THUNDERSTORMS MAY OCCUR, WITH ELEVATED
CAPE PERHAPS 250 TO 500 J/KG. DESPITE THE SHOWERS AND CLOUDS,
HIGHS SHOULD STILL REACH THE UPPER 60S EAST TO AROUND 70 INLAND

THROUGH THE AREA FRIDAY NIGHT, WITH INCREASING SOUTH WINDS
DEVELOPING.

LONG TERM
ISSUED 1158 PM CDT THU OCT 8 2026
SATURDAY THROUGH THURSDAY:
THE GUSTY SOUTH WINDS WILL CONTINUE INTO SATURDAY, WITHIN A
TIGHT PRESSURE GRADIENT. THIS SHOULD BRING VERY WARM
TEMPERATURES INTO THE AREA, WITH 925 MB TEMPERATURES RISING TO
20 TO 21 DEGREES CELSIUS. HIGHS MAY REACH TO AROUND 80 DEGREES
OR INTO THE LOWER 80S. RECORD HIGHS ARE 84 DEGREES FOR
MILWAUKEE AND MADISON, SO THOSE MAY BE APPROACHED.
ONE THING TO WATCH WILL BE PERHAPS A SOUTH SOUTHEAST LAKE
BREEZE DEVELOPING FOR AREAS NEAR THE LAKESHORE BY MIDDAY AND
INTO THE AFTERNOON. THIS MAY HOLD DOWN HIGHS A BIT IN THOSE
AREAS. ALSO, THE CLOUDS ASSOCIATED WITH THE REMNANTS OF THE
TROPICAL CYCLONE MAY PUSH INTO SOUTHEAST WISCONSIN SATURDAY
AFTERNOON, WHICH MAY HOLD DOWN HIGHS A BIT THERE.
ANY RAIN WITH THE TROPICAL CYCLONE SHOULD REMAIN SOUTHEAST OF
THE AREA SATURDAY NIGHT INTO SUNDAY. THERE WILL BE CLOUDS FROM
THIS SYSTEM THAT LINGER SATURDAY NIGHT INTO EARLY SUNDAY IN
SOUTHEAST PARTS OF THE AREA. SUNDAY STILL LOOKS LIKE A WARM DAY,
WITH HIGHS WELL INTO THE 70S INLAND. ONSHORE WINDS SHOULD KEEP
EASTERN AREAS IN THE UPPER 60S TO LOWER 70S.
THERE STILL APPEARS TO BE A COLD FRONT THAT SHIFTS SOUTHEAST
THROUGH THE AREA MONDAY EVENING. ENSEMBLE MEMBERS ARE FAIRLY
WET MONDAY NIGHT, SO KEPT 20 TO 50 PERCENT CHANCES FOR SHOWERS
GOING. SOME THUNDERSTORMS MAY OCCUR AS WELL, AS THE AIRMASS MAY
BE SOMEWHAT UNSTABLE AHEAD OF THE FRONT.
HIGH PRESSURE BEHIND THIS SYSTEM WITH SOME COLD AIR ADVECTION
SHOULD BRING MORE SEASONABLE TEMPERATURES BY THE MIDDLE OF NEXT
WEEK. A MORE ORGANIZED LOW PRESSURE SYSTEM MOVING NORTHEAST
THROUGH THE REGION LATER IN THE WEEK MAY BRING A BETTER CHANCE
FOR SHOWERS AND PERHAPS SOME STORMS.
