Oh stop your whining. Yes, you. I know it's buried somewhere in the Constitution - or maybe the Bill of Rights? I should have paid attention in history class. Yes, it's our God-given right to honk, bellow and bray about the vicissitudes of the weather. It's just all SO unfair!
A dollop of perspective is in order. April 2015 is still running 3.5F warmer than average, to date. We've picked up .3 inches of snow this month. That compares to 7 inches in April, 2014, and a whopping 21.8 inches of snowy fun in April, 1983. That was my first full month living at MSP. I remember wondering what parallel universe I had tumbled into.
So it hasn't been that rough a spring, all things considered. Moisture has been sparse though, lake water levels are down; all but far southeast Minnesota is in moderate drought. A 3-day soaking qualifies as "good weather" this year.
NOAA's NAM model prints out .76 inches of rain Friday night but I think that may be generous; once again the brunt of the rain is forecast to pinwheeling south of Minnesota. Long-range ECMWF guidance shows a string of 70s next week, even a shot at 80F. It will feel like spring again next week.
In today's blog: dual polarization Doppler at 152 National Weather Service sites is so sensitive it can see the "debris ball" of a tornado on the ground. That should mean fewer false alarms.

* If you've smoked at least 100 cigarettes over the course of your life you are at increased risk of COPD. Phil is a dear friend of mine (we worked together at WLOL-FM). He isn't letting COPD slow him down, but his mission is to raise awareness among the general population. Many people have COPD and they don't even realize it yet. Take the screening test from the COPD Foundation; it takes a minute or two.

What the present paper shows is that future changes to clouds will cause slightly more warming. Scientists describe clouds as a “positive feedback” on global warming. This finding is consistent with the work of Dr. Andrew Dessler. He had published work here and here showing changes in clouds are making the Earth warm more than otherwise expected..."
