CONTINUE TO MOVE THROUGH THE AREA THROUGH MONDAY NIGHT. SOME
MIXING DOWN TO THE SURFACE IS POSSIBLE ON MONDAY.

SHORT TERM
ISSUED 217 PM CDT SUN JUN 1 2025
REST OF THIS AFTERNOON THROUGH MONDAY NIGHT:
HIGH PRESSURE REMAINS IN CONTROL ACROSS THE REGION TODAY.
NORTHWEST FLOW ALOFT CONTINUES TO BRING ELEVATED WILDFIRE SMOKE
FROM CANADA SOUTHWARD INTO THE CENTRAL PLAINS AND GREAT LAKES,
RESULTING IN FILTERED SUNSHINE ACROSS THE REGION. WINDS WILL
REMAIN LIGHT AND VARIABLE THIS AFTERNOON, WITH A LAKE BREEZE
PROGRESSING WESTWARD THROUGH THE EARLY EVENING.
NO CLOUD COVER IS EXPECTED OVERNIGHT TONIGHT, BUT MODEL GUIDANCE
DOES SUGGEST THE ELEVATED SMOKE MAY BECOME MORE DENSE. LOWS
TONIGHT WILL FALL INTO THE UPPER 40S AND LOW 50S.
DRY WEATHER CONTINUES ON MONDAY, BUT WITH MUCH WARMER
TEMPERATURES AS BREEZY SOUTHWEST WINDS ADVECT A WARMER AIRMASS
INTO THE REGION. HIGHS WILL GENERALLY BE IN THE LOW TO MID 80S,
WARMEST WEST OF MADISON. DEEPER MIXING ON MONDAY MAY ALLOW SOME
OF THE AFOREMENTIONED WILDFIRE SMOKE TO MIX DOWN TO THE SURFACE
DURING THE AFTERNOON.
WINDS WILL REMAIN BREEZY OVERNIGHT MONDAY NIGHT INTO EARLY
TUESDAY, AHEAD OF AN APPROACHING COLD FRONT. THIS WILL SUPPORT
MORE MILD TEMPERATURES, WITH LOWS ONLY FALLING INTO THE LOW TO
MID 60S.

LONG TERM
ISSUED 217 PM CDT SUN JUN 1 2025
TUESDAY THROUGH SUNDAY:
WIDESPREAD RAIN AND THUNDERSTORMS ARE EXPECTED LATE TUESDAY
MORNING/EARLY TUESDAY AFTERNOON THROUGH THE MORNING ON
WEDNESDAY, AS A SLOW MOVING COLD FRONT PROGRESSES EASTWARD
THROUGH THE AREA. A FEW STRONG STORMS WILL BE POSSIBLE WITH THIS
SYSTEM, BUT WEAK LAPSE RATES AND OVERALL LIMITED INSTABILITY,
ALONG WITH SHEAR LARGELY PARALLEL TO THE BOUNDARY, WILL KEEP THE
SEVERE RISK ON THE LOW SIDE. SEVERAL ROUNDS OF MODERATE TO
LOCALLY HEAVY RAIN ARE EXPECTED THROUGH WEDNESDAY MORNING.
ENSEMBLE PROBABILITIES SUGGEST A GOOD CHANCE (60-70%+) FOR AT
LEAST ONE INCH OF RAIN, BUT VERY LOW CHANCES (<10%) OF SEEING
MORE THAN 2 INCHES. THIS IS SUPPORTED BY DETERMINISTIC OUTPUT
GENERALLY FALLING BETWEEN AN INCH AND INCH AND A HALF IN MOST
LOCATIONS.
THURSDAY IS CURRENTLY LOOKING MOSTLY DRY, THOUGH A STRAY SHOWER
ISN'T OUT OF THE QUESTION. BEYOND THAT, GUIDANCE DIVERGES QUITE
A BIT, ESPECIALLY WITH THE EVOLUTION OF A CLOSED LOW OFF THE
SOUTHERN CALIFORNIA COAST. ENERGY FROM THIS FEATURE MAY BE OUR
NEXT WIDESPREAD RAIN MAKER, BUT COULD ARRIVE LATE IN THE WEEK,
OVER THE WEEKEND, OR NOT AT ALL. OTHERWISE, TEMPERATURES
THROUGH THE REMAINDER OF THE EXTENDED SHOULD GENERALLY BE
AROUND AVERAGE FOR THIS TIME OF YEAR.

AVIATION
ISSUED 217 PM CDT SUN JUN 1 2025
VFR CONDITIONS WILL PREVAIL THROUGH MONDAY. A LAKE BREEZE TODAY
WILL BRING EASTERLY WINDS NEAR THE LAKE, WITH THE BOUNDARY
PROGRESSING WESTWARD LATE THIS AFTERNOON INTO THE EARLY EVENING.
WINDS THEN TURN SOUTHERLY TO SOUTHWESTERLY TONIGHT, WITH BREEZY
SOUTHWEST WINDS PERSISTING ON MONDAY. SOME ELEVATED WILDFIRE
SMOKE MAY MIX DOWN TO THE SURFACE ON MONDAY; IF SO, A LIGHT HAZE
WILL BE POSSIBLE.
BOXELL
MARINE
ISSUED 217 PM CDT SUN JUN 1 2025
LIGHT TO MODEST SOUTHERLY WINDS WILL DEVELOP TONIGHT INTO
MONDAY NIGHT, BECOMING A BIT BREEZY OVER THE NORTH HALF OF THE
LAKE FOR MONDAY AFTERNOON AND NIGHT. BREEZY SOUTHERLY WINDS WILL
THEN DEVELOP OVER THE ENTIRE LAKE FOR TUESDAY INTO TUESDAY
EVENING AS A CANADIAN COLD FRONT APPROACHES FROM THE NORTHERN
GREAT PLAINS. THE COLD FRONT WILL THEN PASS LATE TUESDAY NIGHT
INTO WEDNESDAY MORNING WITH WINDS SHIFTING TO THE NORTH BEHIND
THE FRONT.
INCREASED WINDS AND WAVES WILL LIKELY RESULT IN A SMALL CRAFT
ADVISORY FOR THE NEARSHORE WATERS ON TUESDAY AND TUESDAY NIGHT.
