I hope you enjoyed the sunshine Wednesday. Highs reach the upper 40s to middle 50s across the region which isn’t too bad for Halloween. It will be nice having that gusty wind die off Wednesday night. It will stay tranquil into Thursday with partly cloudy skies. Lows will sink to near 30 with the highs rebounding to the mid or upper 40s Thursday afternoon.
Wednesday night: Partly cloudy. Low: 30 Wind: Light West becoming N late
Thursday: Partly cloudy and tranquil. High: 47 Wind: NNE around 5
Friday will probably be cloudier as the remnants of a small disturbance in the Plains moves in. It appears most of the moisture with it will dry up before getting here. So we just have a slight chance of some sprinkles or flurries. Lows will be in the upper 20s with cool highs around 43.
A stronger low pressure system is projected to move into the area Saturday night and Sunday from the southwest. Thus we have a high chance of rain and snow Saturday night, changing to all rain Sunday. It appears it will be a decent soaking with a general .30 to .50 an inch possible. At this point it looks a bit too warm for much in the way of snow accumulation, but again some flakes could be mixed in Saturday night into early Sunday morning. Highs over the weekend should reach the mid 40s with lows around 30 Saturday and the mid 30s Sunday.
That low pressure system could still throw a few light rain showers on us Monday as it departs just to our east. There will be little change in temperatures. The forecast for the middle of next week is very uncertain yet. There still is some potential of a powerful storm system to develop toward southern Illinois Tuesday, lifting northeast somewhere up into the Great Lakes region. Some models hint it will track far enough east to have only minor impacts on our weather in Wisconsin. Meanwhile some others suggest it will create a good deal of precipitation and strong winds, especially in eastern Wisconsin. We will just have to monitor the situation and fine tune the forecast as it gets closer. At this point we are calling for a low chance of some light rain and snow Tuesday and Wednesday with highs in the lower 40s. Colder air could move in after that.
Have a great evening! Meteorologist Tony Schumacher, 3:05 p.m., 31-October 2018
