Oh brother. The entire weather blog should be a series of apologetic disclaimers today. We still don't know what we don't know, but models continue to suggest accumulating slush late in the weekend, especially Sunday night when we lose the sun's infrared radiation. No problems today; the sun may even peek through. Saturday looks tolerable, but Sunday will be a good Netflix-day with a cold rain mixing with or even changing to wet snow late. Monday, the 1st day of May, could bring plowable amounts of snow to portions of Minnesota. Where those heavy snow bands will set up is anyone's guess right now. Stay tuned.
Well, at least you won't be distracted by blue sky and chirping birds anytime soon - easier to focus on work, school and errands. Flurries may provide a mild jolt today; models still hinting at accumulating slush by Monday (but it's wildly premature to speculate about amounts). Spring fever returns in roughly one week. That's the thing about spring - across most of the USA it's taken as a foregone conclusion. Here in Minnesota, not so much. Minnesotans earn their springs.
We're paying a steep price for last weekend. I grant you it was very nice, especially Saturday, but I would have taken 10 degrees off the afternoon high temperature just to avoid saying the s-word again. Then again, July is the only month where snow hasn't been reported somewhere in Minnesota. Share that with a friend if you're hoping for shocked silence.
Monday turned out a little nicer than expected: low 70s with glimmers of sun. I think it sprinkled for 3 minutes or so. Not bad at all. We got all that "nice weather" out of the way, now it's time for a little payback, served runny and cold. Just rain today into much of Wednesday, but enough cold air may mix down for a slushy mix Wednesday PM, even an inch of snow close to the MSP metro by Thursday morning. Spring in Minnesota is a cool, cruel mistress. You'll see.
OK, so it will be tough topping this past weekend for beauty and splendor. Highs near 70s with generous sunshine, at least from the Twin Cities on south. North of MSP it got gray and chilly in a hurry. A few showers pop today with more 60s, and then a relapse arrives with jacket-worthy 40s, maybe even a few inches of slushy snow by Wednesday across parts of central and northern Minnesota. Isn't April fun?
