Rain will move in Sunday to southern Minnesota, bringing potentially over an inch of moisture with it through the early part of the week. While a few flakes may mix in (mainly early Monday then again Monday Night), the best chance of any accumulating (and plowable) snow will be off to the north and west of the metro.

Look at the bright side, we could be tracking tornadic thunderstorms....or flash flooding...or river flooding...or wildfires. A little slush won't hurt anyone on Monday, and whatever falls should be gone by Tuesday. 75-150 miles north and west of MSP may be a different story with enough snow to shovel and scrape, delighting locals! Hard to believe but we should be in the 60s next weekend as spring stages a comeback. Whew...
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.
