A forecast of "6 more weeks of winter" on February 2 - at our latitude - has a very high probability of verifying. No great surprise, but we'll just have to be content with (mostly) 40s in the coming days. A few 50s sprinkled in to keep us moderately sane, but nothing remotely resembling a warm front. I'm relieved, no mosquitoes, wicked thunderstorms or mulching duties anytime soon...whew.
We're down to a trace of snow (officially at MSP International) but I still have 3-4 foot piles of snow in my yard, and they won't be going anywhere anytime soon, it seems. Our slow meltdown drags on - no 50s or 60s imminent, but rain late in the week may accelerate melting. Today the atmosphere is cold enough for a coating of slush by tonight; maybe a couple inches west and southwest of MSP
A round of light snow is expected Monday Night into Tuesday, with the highest amounts (up to 3") across western Minnesota. Highs in the 30s and 40s are expected this week, and we're keeping an eye on a late week/early weekend storm. Click for details! - D.J. Kayser
Clouds increase today and a light mix is possible Tuesday into Wednesday. A more significant period of rain coupled with mid-40s will accelerate snow melt later this week, and models hint that a cold rain may end as wet snow next weekend. Keep a shovel handy just in case. Check the blog for more details. -Todd Nelson
Our well-timed sunny streak continues into most of the weekend with temperatures above average. Today's forecast calls for showers of green beer set against a royal-blue sky. If everything goes just right we should hit 50F. We cool off early next week; just a generic cool front before another warm-up the latter half of next week.
