The past 7 days have been very busy in the weather department. It started on Sunday with the hottest day of the year where high temperatures reached the upper 80s and lower 90s.
We are still searching for our first 90º day in many cities in southeast Minnesota, if we don’t see it, it will only be the fifth year on record to not reach 90º. Rochester’s yearly high temperature of 87º (felt on Sunday) is still cool enough to have it tied as the coolest high temperature in a calendar year.
After our hot Sunday, Monday was a transition day with cooler, drier weather in place for Tuesday and Wednesday. On Thursday our short lived dry stretch came to an end with a steady, soaking rain falling almost all day with pockets of heavy rain. Most cities in our community ended up with 0.75 – 2 Thursday through Friday morning.
More heavy rain arrived Friday, especially Friday night into Saturday. By Saturday the 3-day official total for rainfall for some communities almost reached 4”!
We are expecting our dry conditions to last most of Saturday and Sunday until late afternoon. Late on Sunday our weather turns wet once again with thunderstorms forming by late afternoon/early evening and lasting through Monday morning.
Some strong to severe storms are definitely possible as these thunderstorms form along a cold front. The risk for severe weather is greater to our west, but as storms move eastward towards MN/IA a few severe storms may remain.
The main threats for any severe storms that develop will be hail and damaging wind, an isolated tornado cannot be ruled out and although heavy rain is expected, the threat for flash flooding is low.
Pockets of very heavy rain will likely occur Sunday night/Monday morning but it is hard to pin point exactly where those heavy pockets will form. Most of us should expect 1-2” with isolated locations expecting more.
After noon on Monday we have a few more dry days moving our way, but this recent stretch of wet weather we have been going through should be enough to vanquish any signs of abnormally dry conditions across our area and eliminate any precipitation deficit.
