2017 PRELIMINARY Tornado Count
According to NOAA's SPC, the PRELIMINARY tornado count for 2017 is at 410 (thru March 29). Interestingly, this is the highest number of tornado reports (thru March 29th) since 2012 when nearly 500 tornadoes were reported through that time frame. The 2005-2015 average number of tornado reports through March 29th is 214.
Precipitation Last 90 Days
Here's an interesting map! The radar estimated precipitation over the last 90 days suggests that nearly 40"+ of liquid precipitation has fallen across parts of the Western US since the end of December 2016! A steady stream of Pacific moisture earlier in the year really helped to boost precipitation values across the region.

Happy last day of March 2017! Are you sad to see it go? It has been in interesting month, no question. From our earliest Minnesota tornado(es) on record (March 6th) to a persistent southerly storm track keeping snowfall amounts down, March 2017 has been a memorable one.
Note that March is typically the 3rd snowiest month for the Twin Cities, which averages a little more than 10 inches. This year, we are running a deficit of nearly 5 inches, bringing our seasonal snowfall deficit to a little more 20 inches. Snow shovels across Central Minnesota were cheated this year, while those in southern Minnesota were put to extra use. Rochester, MN has seen more than 50 inches of snow this season, nearly 5 inches above average.
Average temps in the Twin Cities were running below average through mid March, but have since warmed. It'll be close, but March 2017 will likely end up being the 19th consecutive month with above normal temps! Unreal.
Mild sunshine will brighten spirits Friday. Clouds thicken Saturday and give to showers Sunday.
Average: Low: 30F (Record: -1F set in 1969)
