LATEST FORECAST DISCUSSION
Meteorologist: Monica Ott
*TEMPERATURES WILL REMAIN 5-15 DEGREES BELOW AVERAGE RIGHT THROUGH THE WEEKEND*
A cooler but much more typical start to the morning with temperatures in the 40s. This is much cooler than yesterday but right where we should be for this time of year. A few clouds are hanging around but the area remains dry.
A quiet and dry day ahead with a weak area of high pressure over the region. Clouds will be mixing with sunshine and it will continue to be breezy with highs around 60. Clouds will then start to increase again at night as a low slides out of Canada to our northwest and drags another front through Wisconsin on Thursday. Moisture will be limited on the southern side of this system so overall rain chances aren't very high, with just scattered showers in the area. Much of the day will turn out dry with more clouds than sun. We could warm a few more degrees as winds briefly go back to the southwest out ahead of the front. Highs will be in the low 60's. The front will then slide east, returning a northwest flow and dropping even cooler air into the state by Friday.
The work week will finish up with cool and mostly dry weather, though a few sprinkles may be around the area Friday. A large high pressure system is now forecast to slide out of Canada and down into the Plains during the day, while we still have some upper level energy working through the area. It will be another breezy day and highs look to be no better than the mid 50's. Winds will then diminish and as the high works into the Upper Midwest, the sky will likely clear, leading to a colder start Saturday. This will lead to our first real chance at a widespread frost in Western Wisconsin. We are looking at temperatures dropping into the low and mid 30's which could be enough to bring the growing season effectively to an end. Outside of this, it will be dry Saturday with a partly sunny sky and highs will only be in the low 50's.
By Sunday we should see clouds returning from the south where a front and developing low will be situated in the Eastern Plains. Movement and timing of this system has been changing over the last few days so the forecast becomes more uncertain at this time, but we could see some showers begin to develop by late on Sunday. Chances will then increase at night and into Monday when this system is forecast to work through the state. It should also bring milder air back north, with temperatures rising back into the 60's.
