There's no doubt about it at this point. Spring is here much earlier than the past two years. One graphic pretty much tells the story. Here's a comparison of snow cover across Minnesota on March 30 for the past three years.
Our transition to April this year is warm and potentially bumpy. A spectacular spring Tuesday gives way to a warm and thundery Wednesday. Thursday brings cooler breezes, but even cold fronts now still bring above average temperatures.
Wednesday's low pressure system grabs hold of moisture and triggers rainfall as it passes over Minnesota. A warm breezy start should lead to towering cumulus clouds overhead by lunchtime. Its going to be touch and go to see if storms blossom right over the metro, or just off to the east.
There should be enough instability to trigger a few borderline severe storms capable of high winds and hail Wednesday afternoon. NOAA's Storm Prediction Center assesses the risk area.
I'll call the risk for storm in the metro and southern Minnesota slight for Wednesday afternoon.
Bottom line? Severe weather is possible. Stay situationally aware for rapidly developing storms that could contain downpours, hail and high winds. Severe weather watches and warnings are possible Wednesday afternoon.
Lake Wobegon forecast: Above average
Even with our late week cool down, temperatures run generally warmer than average for this time of year through the weekend.
Play Ball! Twins home opener on the horizon
A sure sign of spring in Minnesota? The Twins home opener is just two weeks away. The forecast will probably change three or four times between now and then. But the early indications from NOAA's Global Forecast System model hints at a potentially warm and sunny opening day in the 70s for April 13.
For now it appears temperatures favor a warm bias from Minnesota southward through the first half of April.
We'll probably see a cool bump here and there, but all indications continue to support my assessment that spring has sprung early in Minnesota this year.
