2/10ths of an inch of snow fell yesterday morning at MSP International Airport.

I don't like hearing the word "oops" when I'm around pilots, surgeons or tax accountants. And yet that's exactly what tumbled out of my mouth yesterday, watching a vigorous snow squall slush up the parking lot. "Did you predict this Paul?" my colleagues asked.
"How 'bout those Twins!" I answered, changing the subject.
In spite of towering technology: Doppler, the ECMWF model and bright, shiny weather objects there are still times Mother Nature throws us a curve; faces pressed up against the nearest window in shock and awe.
Yesterday a puddle of cold air aloft, an "upper air disturbance" sparked enough instability and upward motion for spring showers - and the lowest mile of the atmosphere was just cold enough for snow.
With any luck I won't be using the S-word again for a good, long time. After false starts spring blooms over the weekend as temperatures surge into the 60s; 70F not out of the question Sunday, again the middle of next week. A thundershower may sprout Sunday, with another chance of showers next week. No serious weather drama anytime soon, I'm happy to report.
On the weather blog below: a quieter hurricane season and are we turning the corner into a wetter pattern?

Bruce Rauner declared DeKalb and Ogle counties affected by the severe storms and tornadoes as disaster areas." (AP Photo/Daily Chronicle, Danielle Guerra).

Scientists Explore Changes to Tornado Warnings. WOODTV.com in Grand Rapids, Michigan has the story - here's an excerpt about Doppler radar that caught my eye:
- Radars have changed the way they scan the skies to better spot small tornadoes. Now when a storm is near, a radar is programmed to scan the base of a storm more frequently. This could help spot quick-starting tornadoes, like the one that rolled through Kentwood in 2014 un-warned.
- National Weather Service radars are all now “Dual-Pol,” which means they send out horizontal and vertically propagating microwaves. This helps meteorologists identify the size and shape of particles in the sky, which means the radar can identify debris from tornadoes on the ground...
