Our Fleeting Spring
On KARE-11 Julie Nelson called it a "clingy winter", which sounds right. Like an annoying ex who posts inappropriate comments on your Facebook page. Depressed? My mom reminded us to "memorize the bad moments, because it makes the good times even sweeter."
Weather, like life, is cyclical.
One theory: 2012's record melting of Arctic ice knocked the jet stream out of alignment, displacing cold air south. Weather usually tracks west to east, but in recent months we've seen a sweeping north-south flow. Steering winds have buckled - pulling Gulf moisture north, erasing drought - while March-like air spills south, setting the stage for freak blizzards and May snowfall records.
Drier air pushing in from Wisconsin brightens skies today, with highs near 60F. Moods lighten Monday as highs nudge 70F, in fact lukewarm weather lingers all next week.
Dear diary: we're about to experience a May warm front.
Showers & T-storms sprout Wednesday into Thursday. Minnesota's Fishing Opener is next weekend; a cooler front sparks a few showers late Saturday & Sunday.
The ECMWF hints at an airmass cold enough for flurries one week from tomorrow, further delaying heat, tornadoes, bugs & humidity.
Insert gasp here.
April Numbers. April was more than 6F colder than average, 2.56" wetter than normal, with nearly 18" of snow (which is 15.5" snowier than average). More March than April. More details from the Twin Cities National Weather Service.

- April precipitation totals were
well above historical averages in the eastern one-half of Minnesota,
near to below historical averages for the western one-half of the
state. For many southeast Minnesota counties, monthly precipitation
totals topped the long-term average by more than three inches, erasing
drought concerns in those areas. Many observers reported measurable
precipitation on more than 20 days during the month. Some observers
reported precipitation on 10 or 11 consecutive days.

- Ten winter storm warnings and numerous winter weather advisories were issued for Minnesota counties by the National Weather Service during the course of the April. Frequent, and often heavy, storms piled up snowfall totals to record or near-record levels at many locations. Historical average monthly snowfall totals range from two inches in southern Minnesota to six inches in northern counties. In many Minnesota communities, April 2013 monthly snowfall totals exceeded 12 inches. Numerous locales reported monthly snowfall totals in excess of 24 inches. The focal point for the heaviest of the April snowstorms was northeast Minnesota, particularly Duluth, where April snowfall reached historic levels. The monthly snowfall total at Duluth's International Airport was an astounding 50.8 inches. Not only did this top the previous April record by nearly 20 inches, it was Duluth's snowiest month ever for any month of the year. The April snow and cold snarled roads, delayed agricultural field work, canceled outdoor events, and postponed natural signs of spring by many weeks.

"That Tweet likely articulates Google’s biggest fear for Glass, its wearable computer. What if the cool crowd doesn’t accept it? What if, like the Segway, it becomes an emblem of the awkwardly nerdy? What if consumers reject the technology because, even though it’s amazing, there’s too much social stigma to being seen in public with it?..."
