Milwaukee stays sunny Sunday, with temperatures reaching about 66 degrees. Northwest winds near 10 mph are expected, and rain is not in the forecast, according to the National Weather Service’s updated Milwaukee forecast.
Clear skies continue Sunday night as temperatures fall to around 43 degrees. Northwest winds around 5 mph may make the evening feel crisp. Monday remains sunny and dry, with a high near 61 and northwest winds around 5 mph, according to the National Weather Service forecast.
The National Weather Service’s Milwaukee-area outlook flags a chance of patchy frost tonight in valleys and low-lying areas, but says no hazardous weather is expected Monday through Sunday. The outlook is a heads-up about localized overnight conditions, not a frost advisory specifically for Milwaukee County. The latest Milwaukee/Sullivan hazardous-weather outlook gives the area forecast.
Tuesday is expected to bring the week’s highest temperature, according to the National Weather Service’s updated forecast.
The forecast calls for a sunny high near 69 degrees Tuesday, with south winds of 5 to 15 mph and gusts as high as 25 mph. Wednesday is expected to be sunny with a high near 68; Thursday and Friday should be mostly sunny, with highs near 66 and 65, respectively, and Saturday sunny near 67, according to the National Weather Service’s current Milwaukee forecast.
That forecast describes the coming days, not a long-term climate pattern. Separately, the Wisconsin State Climatology Office reports that temperatures have risen since 1950 in Richland County and says the pattern also applies to most of Wisconsin. Its finding covers annual and seasonal time scales; it does not establish an October-specific trend or explain this week’s forecast.
The long-term trend is measurable: since 1950, Richland County’s annual average temperature has risen about 0.4 degrees Fahrenheit per decade, while its average winter temperature has climbed 4 to 5 degrees. The State Climatology Office says the warming pattern also applies to most of Wisconsin, with winter warming more than other seasons. Those historical averages describe decades of change, not what caused any particular sunny or warm day in Milwaukee. The Wisconsin State Climatology Office’s county profile details the trend.
