Public weather briefingAfter a cloudy Tuesday, the good chance for clear conditions into the rest of the week continues. High pressure moves into the area tomorrow from Canada, providing calm conditions for the week ahead. Along with this, another high pressure system from the Rockies has an impact in the region later in the week providing for more mild conditions. Low temperatures tonight will be cold at just below 20 degrees. Daytime high temperatures will slowly increase throughout the week providing for a very comfortable weekend, temperature wise. It is looking very likely for above 40 degree highs for the weekend. Partly to mostly sunny skies are the main feature for the middle to end of the week, before the clouds return for end of the weekend. Also, the possibility for rain or snow comes into the picture at the start of next week. Attributed to this is a low pressure system to the west along the Great Plains and north into Canada.
Tonight. Partly cloudy and light winds. Low around 20.
Wednesday. Mostly sunny with light winds. High around 30.
Wednesday night. Clear and cold. Low in the upper teen's.
Thursday. Sunny and cool. Light winds. High of 35 and a low around 23.
Friday. Continued sun and warmer with a high in the upper 30's. Low in the mid 20's.
Outlook for Saturday through Monday. Clear Saturday, before clouds return Sunday and Monday. Very nice temperatures in the mid to up 40's for Saturday and Sunday before cooling to the upper 30's on Monday. There is likely going to be precipitation along with the cooling Monday. Probably a mix of snow and ice.[CONFIDENCE: MEDIUM-HIGH]
Late Thursday, into Friday, a secondary anticyclone from the Rockies, mentioned yesterday is likely to travel through the southern plains and eventually keep moving west to east through the central U.S., missing the upper Midwest to the south. The effects are still felt however, as there will be warm air advection from the south giving us warmer than average temperatures for the weekend. Along with this are clear conditions for most of the weekend as well.
Later in the forecast, Sunday, a low pressure trough pushes its way south from Canada into the Wisconsin region. This brings ascending air and clouds return to the forecast along with a small chance of showers.
After this pressure trough from the north, a low pressure system to the southwest, centered over the Great Plains brings in colder conditions and a good chance for a rain/snow mix on Monday. There will most likely be rain during the morning/afternoon when temperatures are higher, and then snow once the cold front moves in and daytime highs end.
