Regional Weather View.

Some of the region will be getting their first real measurable snow this weekend as a system passes through Iowa then through central Wisconsin. Minor accumulations of snow is possible across much of Minnesota and Northern Wisconsin. But some significant accumulations are possible in South Dakota, and the Snowbelt areas of Northern Wisconsin. Further south a mixture of rain sleet and snow is possible in a narrow area from Central Wisconsin to southern Minnesota to Northwest Iowa. South and east of here light drizzle is all that is likely. There will be a very large temperature difference from north to south. Northwest Minnesota will have teens for highs, while southern Iowa and Missouri will have lower 60s. Arctic air will move in behind this system and cool everyone down.

Local View.


This system for the area will not be a major issue. But becuase of where it is expect to go, we will have to deal with a mixture of light rain, sleet and snow. With temps starting off the the upper 30s, Light rain or drizzle will start during the day Saturday. amounts will be a quarter inch or less. But as the system slides a bit more eastward, temps will plummet into the mid 20s, changing precip from rain to sleet and eventually snow, But by this time most of the precip will have moved to the east. So this will limit accumulations up to 1 inch for place like Cannon Falls and Red Wing where this changeover will occur first. For the rest of the area, a coating to a half inch is possible. Slick roads may be an issue as temps fall and water starts to freeze Saturday Night.  The bigger story with this system for our are will be the very cold air behind it which will settle in Sunday and may come in with a few flurries.I'm calling it arctic air, but really the coldest conditions will stay well northwest of here. Still Even with sunny skies, highs will likely remain at 32.F or below at most areas. Temperatures at night will be well into the upper 10s and 20s. Monday and Tuesday will be slightly warmer with highs in the upper 30s both days, and lows in the 20s.

Saturday, Cloudy with light rain and drizzle developing. Highs in the upper 30s. Saturday Night, Breezy, drizzle or rain changing to sleet, then eventually all snow area wide. Accumulations up to 1 inch far northwest areas, and a coating to 1 inch rest of area. Lows plummeting to the mid 20s by morning.

Sunday, Cold air settles in. Sunny with highs in the upper 20s to low 30s. Sunday Night, Partly cloudy with a chance for a few flurries. Otherwise cold with lows in the upper teens to low 20s.

Monday, Chilly but warmer. Sunny skies, highs in the mid to upper 30s. Monday Night, Clear skies and cold. Lows falling to the upper teens to lower 20s.

Tuesday, Sunny skies with fair temps. Highs in the upper 30s to low 40s. Tuesday Night Clear skies with lows in the low to mid 20s.


Looking Ahead- Thanksgiving Early Outlook!
As we approach the end of the early workweek for many, We will have dry and warming conditions. A mild and dry Thanksgiving weekend looks likely at this point, with sunshine and 40s for highs, possible nearing 50 or above towards Friday/Saturday! Saturday night a weak system may produce a few light rain showers, making way for a clear Sunday the 27th. Tuesday the 29th a cold front pushed Southward, which may produce a few light snow showers here. The only threat of any significant snow does not appear until Sunday December 4th, when a system passes to out southeast. It looks too far east at this time to effect our area, but as many know this will change. Check back for updates.
