More From Paul Douglas on Weather
For the first time in 20 months we may experience a cooler than average month in the Twin Cities. May has been cool, gray and wet. Let's hope the pattern warms up and dries out a little in June, although I'm not holding my breath. Today will be foul, but skies clear Wednesday with a shot at 70F. We may top 80F Friday before a swarm of T-storms arrive, a cooling wind may kick in again next weekend. I know - I'm just as annoyed as everyone else.
Sunday wasn't a total loss, in fact much of the day was just fine over central and southern Minnesota with plentiful sunshine and temperatures close to average. Instability showers and T-storms quickly sprouted, putting a damper on outdoor activities by late afternoon and evening. Expect more clouds and numerous showers again today - if it's any consolation it's too cool for anything severe out there. We warm up by late week but I see a persistent cool bias into at least the first week of June, maybe longer.
We salvaged a half-decent Saturday; nicer weather north of the cities, but at least it was lukewarm. A northwest wind kicks in today and Memorial Day as cooler air drains south out of Canada. It's even colder aloft, and heating of the ground will spark showers, mainly PM hours, the next couple of days. Not a total loss, but a few showers and sprinkles are likely. Summer could make an appearance by next weekend; details in the blog.
Friday was probably as good as it's going to get in the weather department anytime soon. 80 degrees, sunshine, a gentle breeze. Today will be a bit cooler and cloudier with showers likely over southern Minnesota. There will be some sunshine out there, especially central and northern Minnesota today, but the trend over the next 2-3 days will be more clouds, more wind and more numerous showers. Lousy timing: Monday appears to be the coolest, wettest day - although it won't be an all-day rain.
Thursday was a step in the right direction and today and much of Saturday will be fairly nice with 70s and sunshine much of the time. A shower or T-shower is possible late Saturday, likely Sunday and Memorial Day. No all-day washouts, but have a Plan B, especially for Monday. Pretty typical for a holiday, all things considered.
