QUICK LINKS:

If you spent prolonged time outside on Friday, Saturday or Sunday and didn’t have to dig out the hats, gloves and jackets then you are a braver person than me. Friday was our day of transition when temperatures in the early morning started in the lower 50s (which would be the high temperature of the day), cooled to the lower 40s in the morning then barely rose to the middle 40s in the afternoon. By the time we reached midnight Friday night into Saturday our temps were already in the 30s.

Besides being chilly, Friday was a very windy day. Wind gusts as high as 43 mph were reported across the area Friday afternoon. This pushed wind chill values into the 20s for Friday night.

Friday night brought a round of very light rain & snow showers. Almost all of our communities in southeast Minnesota & northern Iowa picked up their first trace of snow. Over the border in Wisconsin as high as 1 – 1.5” of snow fell!

Rochester International Airport picked up a trace of snow on both October 3rd & October 4th. Seeing a trace of snow on the 3rd tied a record & picking up a trace of snow on the 4th was the first time Rochester has ever seen snow on the date.

It was definitely a little early to be seeing snow. Typically the first trace of snow doesn’t fly until the second half of October on the 20th.

If the snow Friday night wasn’t enough, Saturday morning we woke up to the coldest temperatures since the end of July with lows at or barely above 32º.

That chill lasted through most of Saturday leading to an even colder Sunday morning. Widespread frost settled in across the region with some areas of freeze occurring to our NE in Wisconsin. Pretty much every community in our area has now picked up their first 32º night, but we still haven’t seen a killing freeze that usually occurs around 28º.

Now for the good news, bad news. Good news: Temperatures in the week ahead will not be nearly as cold as the weekend. Bad news: Temperatures in the week ahead will stay below average (but only by a few degrees).
