KEY MESSAGES
- DRY WEATHER UNDER HIGH PRESSURE EXPECTED THROUGH THE WEEKEND
AND INTO NEXT WEEK. FIRE WEATHER CONCERNS MAY INCREASE INTO
EARLY NEXT WEEK.
UPDATE
ISSUED 530 PM CDT THU MAY 28 2026
THE BREEZY NORTHEAST WINDS FROM EARLIER IN THE DAY ARE ALREADY
STARTING TO COME DOWN ACROSS SOUTHERN WISCONSIN. WINDS WILL
CONTINUE DECREASE BECOMING LIGHT AND VARIABLE TONIGHT. WITH THE
CLEAR SKIES TONIGHT THERE IS A SMALL CHANCE FOR SOME PATCHY FOG.
THIS WILL LARGELY BE LIMITED TO LOW LYING AREAS LIKE RIVER
VALLEYS AND MARSHES. THIS IS DUE TO THE LIMITED AVAILABLE
MOISTURE. DEWPOINTS ARE IN THE MID TO LOW 40S ACROSS MUCH OF THE
AREA ARE EXPECTED TO STAY FAIRLY CONSISTENT THROUGH THE NIGHT.
WITH OVERNIGHT LOWS IN THE UPPER 40S TO LOW 50S, THE DEWPOINT
DEPRESSIONS WILL JUST BE A BIT TO LARGE TO ALLOW FOR WIDESPREAD
FOG.
PATTERSON
SHORT TERM
ISSUED 203 PM CDT THU MAY 28 2026
TONIGHT THROUGH FRIDAY NIGHT:
NORTHEASTERLY BREEZES EXPECTED TO CONTINUE THROUGH THIS EVENING
BEFORE BECOMING CALM AFTER SUNSET AS HIGH PRESSURE SETTLES OVER
THE AREA. A FEW AREAS OF PATCHY FOG ARE POSSIBLE IN LOW LYING
AREAS TONIGHT, BUT DEWPOINTS IN THE LOW 40S WILL PREVENT MOST
AREAS FROM SEEING REDUCED VISIBILITIES AS AIR TEMPS WILL ONLY FALL
INTO THE MID-40S. ANY FOG THAT DOES DEVELOP WILL BURN OFF SHORTLY
AFTER SUNRISE FRIDAY AS TEMPERATURES CLIMB QUICKLY INTO THE UPPER
50S TO LOW 60S FOR THE MORNING COMMUTES. HIGHS IN THE LOW TO MID
80S ARE EXPECTED FROM THE KETTLE MORAINE WESTWARD, WITH HIGHS IN
THE UPPER 70S TO LOW 80S EAST OF THE KETTLE MORAINE. A LAKE BREEZE
WILL PUSH INLAND DURING THE AFTERNOON HOURS FRIDAY, BRINGING HIGHS
RIGHT AT LAKE MICHIGAN DOWN INTO THE 60S. RELATIVE HUMIDITY VALUES
MAY DIP INTO THE LOW 20S, BUT WITH MINIMAL WINDS NOT EXPECTING
FIRE WEATHER IMPACTS. FRIDAY NIGHT, WINDS BECOME CALM ONCE AGAIN
AND LOWS IN THE MID 50S ARE EXPECTED. NOT ANTICIPATING FOG
DEVELOPMENT FRIDAY NIGHT DUE TO WARMER LOWS AND CONTINUED
DEWPOINTS IN THE 40S.

LONG TERM
ISSUED 203 PM CDT THU MAY 28 2026
SATURDAY THROUGH THURSDAY:
A BRIEF BACKDOOR COLD FRONT WILL REINFORCE HIGH PRESSURE SATURDAY,
BRINGING HIGHS IN THE 70S. SUNDAY, WITH HIGH PRESSURE OVERHEAD,

BREEZE INFLUENCE TO KEEP TEMPERATURES LOWER. LIGHT SOUTHEASTERLY
WINDS ARE EXPECTED THROUGH THE DAY SUNDAY. AN ADDITIONAL BACKDOOR
COLD FRONT SWEEPS INLAND FROM LAKE MICHIGAN ON MONDAY AFTERNOON,
BUT THE MAJORITY OF SOUTHERN WISCONSIN WILL STILL SEE HIGHS IN
THE 80S. A FEW SHOWERS AND THUNDERSTORMS MAY DEVELOP ALONG THIS
FRONT DURING THE AFTERNOON AND EVENING HOURS (10-20% CHANCE). FIRE
WEATHER CONCERNS MAY DEVELOP MONDAY AS FUELS CONTINUE TO DRY AHEAD
OF THE FRONT AND GUSTY CONDITIONS DEVELOP BEHIND THE FRONT. HIGH

HIGHS IN THE UPPER 80S BECOMING POSSIBLE BY THURSDAY.

VFR TO MVFR CONDITIONS ARE EXPECTED THROUGH THE PERIOD. THE
BREEZY NORTHEAST WINDS THIS EVENING WILL CONTINUE TO DIMINISH

MADISON. FOR THE FEW TERMINALS THAT SEE FOG, VISIBILITIES ARE
EXPECTED TO FALL TO AROUND 4-7 SM. ANY FOG THAT DOES DEVELOP
WILL DISSIPATE SHORTLY AFTER SUNRISE. THE LIGHT AND VARIABLE
