SHORT TERM
ISSUED 1230 PM CDT WED APR 8 2026
TONIGHT THROUGH SATURDAY:
THE DEVELOPING LOW OUT TO THE WEST WILL BEGIN TO PUSH IN
THIS AFTERNOON WITH THE BASE OF THE LOW AROUND THE CENTRAL
US/CANADA BORDER. THIS LOW WILL DRAG A COLD FRONT THROUGH THE
REGION THIS EVENING/NIGHT. FORCING AND MOISTURE WILL BE
PLENTIFUL HERE WITH THE FRONT AS THE PRIMARY FORCING MECHANISM
WITH SUPPLEMENTAL HELP FROM A LITTLE MIDLEVEL WAA AND SOME PVA
ALOFT EJECTING FROM THE STRONG UPPER LOW OVER SW ONTARIO. PRECIP
MAY BEGIN AS EARLY AS LATE THIS AFTERNOON IN THE NORTHWEST CWA
WITH PRECIP AHEAD OF THE FRONT BUT THE MAJORITY OF IT WILL COME
THROUGH WED EVENING INTO THE OVERNIGHT HOURS PRIMARILY ALONG THE
FRONT. A TINY BIT OF INSTABILITY MAY YIELD A RUMBLE OF THUNDER
OR TWO BUT FOR THE MOST PART THIS IS EXPECTED TO BE MODERATE
RAIN SHOWERS FOR A FEW HOURS IN ANY GIVEN AREA FROM NW TO SE
WITH RAIN PUSHING OUT OF SE WI BY THURSDAY MORNING.
WITH THE FRONT OUT OF THE AREA THURSDAY MORNING EXPECT HIGHER
PRESSURE TO PUSH IN BEHIND IT, THOUGH THIS WILL BE FAIRLY SHORT
LIVED. THURSDAY DURING THE DAY IS EXPECTED TO REMAIN DRY BUT BY
THURSDAY EVENING EXPECT A WARM FRONT TO LIFT NORTH INTO THE AREA
BASED FROM A WEAK LOW PRESSURE DEVELOPING IN LEE OF THE ROCKIES
INTO THE CENTRAL PLAINS. A SHORTWAVE ALOFT, STRONG WAA ON THE
NOSE OF THE LLJ IN THE LOW TO MID LEVELS WITH A MOIST COLUMN
SUGGEST A VERY HIGH CHANCE FOR PRECIP THURSDAY NIGHT WITH A SLUG
OF RAIN EXPECTED. THE BEST CHANCES (90+%) WILL BE FOR THE
SOUTHERN PORTIONS OF THE CWA WITH LESSER CHANCES (40-80%)
TOWARD CENTRAL WI. THUNDER LOOKS UNLIKELY GIVEN THE PROFILES
SUGGESTING VERY LIMITED INSTABILITY BUT WE CANNOT RULE OUT A
RUMBLE OF THUNDER, ESPECIALLY IF THE WARM FRONT LIFTS ANY
FARTHER NORTH THAN CURRENTLY EXPECTED. PRECIP WILL GENERALLY
PUSH OUT SOMETIME FRIDAY MORNING AS HIGH PRESSURE NUDGES IN FROM
THE NORTHWEST, SHOVING THE FRONT BACK TO THE SOUTH. HIGH
PRESSURE WILL CONTINUE TO PUSH EAST BUT WILL STRENGTHEN INTO THE
CENTRAL GREAT LAKES REGION KEEPING US DRY THROUGH THE DAY
SATURDAY. EAST WIND OFF THE LAKE FROM THE HIGH PRESSURE WILL
KEEP US FAIRLY COOL, HOWEVER.
LATER DURING THE DAY SATURDAY WE WILL START TO SEE THE NEXT
SYSTEM START TO PUSH IN AS A LOW DEVELOPS OVER THE NORTH CENTRAL
US. PRECIP MAY BEGIN TO PUSH IN BY THE LATE AFTERNOON.

LONG TERM
ISSUED 1230 PM CDT WED APR 8 2026
SATURDAY NIGHT THROUGH WEDNESDAY:
SOUTHERLY LOW LEVEL FLOW WILL CONTINUE SATURDAY NIGHT THROUGH AT
LEAST MONDAY PER LATEST MODELS, WHICH WILL RESULT IN EVEN MILDER
CONDITIONS LATE WEEKEND INTO EARLY NEXT WEEK. HIGHS INTO THE LOW
TO MID 70S ARE LIKELY FOR SUNDAY AND MONDAY. ADDITIONALLY, EXPECT
PERIODS OF WARM ADVECTION ALOFT AND INCREASING MOISTURE AS A
COUPLE OF SHORTWAVES ROLL THROUGH. THIS WILL BRING MULTIPLE ROUNDS
OF SHOWER/STORM CHANCES SAT NIGHT THROUGH MONDAY. COULD SEE SOME
STRONGER STORMS MONDAY OR MONDAY NIGHT AS THE LOW AND ASSOCIATED
COLD FRONT MOVE THROUGH, THOUGH CONFIDENCE IN LOW
STRENGTH/TIMING/PLACEMENT REMAINS NOT VERY HIGH AT THIS TIME GIVEN
VARIATIONS AMONG THE LATEST MODEL SOLUTIONS. PLUS, THIS PERIOD IS
SEVERAL DAYS OUT, SO PLENTY OF TIME FOR THE FINER DETAILS TO
CHANGE.
KEPT PRECIP CHANCES GOING TUESDAY AS THE LOW SLOWLY EXITS THE
REGION, WITH COOLER TEMPS ARRIVING ON THE BACK SIDE OF THE LOW FOR
MID-WEEK.

AVIATION
ISSUED 1230 PM CDT WED APR 8 2026
BREEZY SOUTH WINDS WITH MOSTLY HIGH CLOUDS OVERHEAD THROUGH
THIS AFTERNOON. A FRONT WILL BEGIN TO MAKE ITS WAY THROUGH
SOUTHERN WI FROM NORTHWEST TO SOUTHEAST LATE AFTERNOON THROUGH
THE OVERNIGHT PERIOD. THIS WILL BRING LARGELY WIDESPREAD SHOWERS
FOR A FEW HOURS TO ANY INDIVIDUAL AREA WITH PERHAPS A FEW
RUMBLES OF THUNDER. A PERIOD OF MVFR CIGS MAY COINCIDE WITH THIS
PERIOD OF SHOWERS BUT IS NOT CERTAIN. IN ADDITION, A PERIOD OF
LOWERED VSBYS MAY COME WITH THE RAIN AS WELL. OTHERWISE LIMITED
IMPACTS TO AVIATION EXPECTED. MORE WESTERLY TYPE WINDS RETURN
BEHIND THE FRONT.
QUIET DURING THE DAY THURSDAY WITH MODEST WEST WINDS AND MOSTLY
CLEAR SKIES. HOWEVER, COME LATE THURSDAY AFTERNOON INTO FRIDAY
MORNING WILL BRING MODERATE TO EVEN HEAVIER RAIN SHOWERS TO MUCH
OF SOUTHERN WI WITH LIKELY IFR/LIFR CIGS AND SOME IMPACTS TO
VSBYS WITH THE RAIN SHOWERS. CANNOT RULE OUT A FEW RUMBLES OF
THUNDER WITH THIS EITHER.

HIGH PRESSURE AROUND 30.6 INCHES HAVE PUSHED INTO THE EASTERN US
WITH A LOW PRESSURE AROUND 29.5 INCHES TRACKING ALONG THE
NORTHERN GREAT PLAINS AND CANADIAN BORDER WILL TRACK NORTH OF
LAKE SUPERIOR TONIGHT INTO THURSDAY MORNING. THE PRESSURE
GRADIENT ASSOCIATED WITH THE LOW AND BEHIND THE HIGH WILL BE
STRONG. THIS WILL RESULT IN VERY BREEZY SOUTHERLY WINDS OVER
LAKE MICHIGAN ON WEDNESDAY WITH GALE FORCE GUSTS UP TO 40 KT. A
GALE WARNING IS IN EFFECT FOR THE NORTHERN THREE QUARTERS OF THE
LAKE THROUGH LATE TONIGHT. GALE WARNING REMAINS IN EFFECT FOR
THE NORTHERN NEARSHORE ZONE AND SMALL CRAFT THE REST OF THE
NEARSHORE ZONES. A SMALL CRAFT WILL FOLLOW FOR THE NORTHERN
NEARSHORE ZONE AFTER GALES SUBSIDE.
BEHIND THE FRONT PRESSURE GRADIENT WILL FALL OFF QUICKLY WITH
HIGH PRESSURE OF 30.2 INCHES NUDGING IN. MUCH LIGHTER WESTERLY
WINDS ARE THEN EXPECTED ON THURSDAY IN THE WAKE OF THE COLD
FRONT. LIGHT AND VARIABLE WINDS WILL PREVAIL INTO SATURDAY,
UNTIL BREEZY SOUTHERLY WINDS RETURN LATE IN THE WEEKEND.
