Too Much Warning?
As technology advances it brings up new opportunities and subsequent challenges. The average national lead-time for tornadoes (from detection to arrival) is 14 minutes, nationwide. Researchers are working on new algorithms that may lengthen that lead time to 45 minutes within the next 3 years. A major advance, right? Absolutely.
But anecdotal evidence suggests that having more lead time allows people to make bad choices: driving home from the office or picking the kids up at school - all of which increase the risk of becoming a tornado statistic. An odd conundrum.
Tornado season peaks in June here in Minnesota; yesterday was just the first warning shot across the bow.
Clouds linger today, the best chance of showers north of the Twin Cities. Fishing Opener starts out cool & dry, but showers push in by afternoon - highs near 60F north to mid 60s metro area.
Take your favorite mom to an early brunch Sunday; clouds thicken on Mother's Day with another surge of rain, heavy at times, Sunday night into Monday. Cool, Canadian exhaust on the backside of this next storm keeps highs in the 50s to near 60F much of next week. Nights dip into the 35-43F range, but no frost. No tornadoes either.

Now A "Pollen Vortex"? Wild Weather May Mean Allergy Nightmare. The polar vortex certainly delayed allergies across most of the USA, but we seem to be rapidly making up for lost time. Here's a clip from NBC News: "...Susan Kosisky, a microbiologist and chief of the United States Army Centralized Allergen Extract Laboratory, reports that daily average pollen counts from her laboratory in Silver Spring, Md., have been 50 percent or below what is normal for this time of year, which she attributes to cold temperatures. But before you throw away the tissues, experts say the slow start could mean a more intense wallop. “It will be a shorter period by a number of weeks but you will see it all hitting very intensely,” says Dr. Shulan..."
