Severe Thunderstorm Watch until 10 PM includes Stearns, Benton and Sherburne
A Severe Thunderstorm Watch has just been issued for the St. Cloud area, including Stearns, Benton and Sherburne Counties. The watch goes until 10 PM, and also includes parts of the northern Twin Cities and the Duluth area. Storms are starting to initiate within the watch area, and could go severe shortly. Large hail up to 1.5 inches in diameter and damaging winds up to 70 MPH appear to be the main threats along with typical cloud-to-ground lightning associated with thunderstorms. I'm not too sure on the threat for the St. Cloud area (front might already be too close), but it does increase as you head east of the area.
What follows below is the watch area image and the statement from the Storm Prediction Center. We will have updated watch areas, warnings and statements as they are issued, mainly ones which impact the STC area.

Snow in May? You betcha!
Ah, Spring in Minnesota. Sure, we've been spoiled so far, especially with a snowless March and April. But snow all the way into May is not as rare as you may think it is.
Overall, the St. Cloud area averages 0.1" of snow during the month of May historically. Here are some other snow facts:
Otherwise, mainly cloudy Saturday with a high around 50, and a mix of clouds and sun Sunday with a high in the middle 50s. Looking into next week: It will stay "coolish" with highs mainly around 60 (except Tuesday with a high in the lower 50s) and a chance of showers Monday into Tuesday, and again late in the week.
Now, embrace the snow. Don't go running away from it. It won't last long. And it is not out of the norm.
Overall, the St. Cloud area averages 0.1" of snow during the month of May historically. Here are some other snow facts:
- The biggest May snow? 3.2 inches on May 19, 1971 -- also the date of the latest inch of snow during the month of May in St. Cloud.
- The latest measurable snowfall? May 23, 1925. BUT snowflakes have been seen up to May 27.
- St. Cloud's last measurable snowfall in May? 0.1 inch on May 1, 2005. If we get a measurable snowfall tonight, it will be the first since then

Weather Watch Likely Soon For Eastern MN
A severe weather watch is likely soon over portions of MN, WI, and IA, including the Twin Cities and Rochester areas. Storms are likely to develop soon, and will at least approach severe limits. The main threats appear to be large hail and damaging winds, though an isolated tornado or two cannot be ruled out, mainly over western WI. Here is the following Mesoscale Discussion from the Storm Prediction Center -- We will follow up with any watches that are issued for the area.

Slight Risk of Severe Storms Thursday
Storm Prediction Center's Slight Risk area for Thursday
We are carefully watching for the possibility of some strong to severe storms over southern Minnesota during the late afternoon and evening Thursday. Currently the Storm Prediction Center has a Slight Risk of Severe Storms over much of southern Minnesota for Thursday as a cold front and low pressure area approaches the area.
Some concerns over the formation of these storms though. It looks as though over a good portion of the Slight area, stretching down to Oklahoma, will be capped, which would limit formation of storms until the cap is broken (think of a shaken up bottle of pop. The energy can't be released until you unscrew (remove) the cap).
Also, at least up in our neck of the woods, we have a dry atmosphere, which will only help set off any storms that we do get.
Percent probability of severe weather within 25 miles of a point -- Hatched (blue dashed area) is probability of significant severe weather within 25 miles of a point
The main threat that should occur with these storms in our area is large hail and some damaging winds. I won't rule out an isolated tornado or two, mainly in southern Minnesota (south of the cities), but the main tornado action (along with the main severe weather event) should be from Iowa down toward Kansas in the afternoon and evening.
I do not think that this will be a big outbreak in our area - more an isolated event. We could see a bigger outbreak, including tornadoes, as the system pushes eastward into Wisconsin, Iowa, Illinois, and south through Louisiana and Mississippi on Friday.
