Chill blunts storms

Paul Huttner and I keep trying to find the silver lining in the extended cool streak this spring. Light snow in northeast Minnesota, temperatures in the 20s and winds to 30 mph on Sunday transitioned into sunshine and an acceptable mid to late afternoon.

So far this month temperatures are running nearly ten degrees below normal along the Minnesota/Canadian border, and about three degrees below normal in central Minnesota. International Falls dipped to 26 degrees on Sunday morning, only two degrees shy of the record of 24 set in 1996.

This cold vortex anchored in the proximity of Hudson Bay is likely to continue the cool trend for the foreseeable future. Below normal temperatures could extend into the next two weeks.

Eight to fourteen day outlook

Severe weather has been the story to our south. The southern boundary of cold air has set up the focus for thunderstorms from Kansas to the Carolinas. There have been about two dozen killer tornadoes so far this season in the United States. The Web site of the Storm Prediction Center is listing a preliminary total of more than nine hundred tornadoes through May 11th.

Preliminary National tornado statistics

Based on rotation indicated on the Doppler Radar, the National Weather Service was able to give about thirteen minute lead time on the destructive tornado along the Oklahoma and Missouri border on Saturday afternoon. The radar signature, as I viewed it in progress, was a classic super cell, with the tornado formation on the southwest tail of the storm.

Showers in northwest Minnesota today expand and move southeast tonight and Tuesday.

    OK, guys….can we cut to the chase here?

    Going back to last October or so, this seems to be about the coldest seven-month stretch I can remember in Minnesota – ever. I’ve lived here 30+ years of my life, and maybe it was colder in the late ’70s, but I don’t remember that very well.

    My point is, that it’s not just that it’s been a “colder than average” winter or “colder than average” spring, but that it’s been consistently colder, in general, over this October-May stretch than any year I can think of. And while this may sound odd to phrase it this way, it’s not necessarily how “cold” it’s been, but also how “not-warm” it’s been – as in, there have been VERY few days that have been at all above-average, while there have been VERY many days that were slightly or greatly below average.

    Am I imagining this? Am I crazy? I don’t think so.

    But if you guys could start digging out some stats to back me up, I (and, I think many other Minnesotans who are similarly losing their minds with all this shivering) would be very grateful.

    Thanks!
