Miserable weekend with temps 30 degrees below normal, maybe even some snow near the Twin Cities

The high Sunday might not get out of the 30s in parts of the metro.

A line of thunderstorms swept through the southern half of Minnesota overnight and was out of the Twin Cities before 7 a.m., setting the stage for what's going to be a rather miserable weekend. 

The high temp Saturday in the Twin Cities will struggle to reach 50 degrees, and simply getting to 40 degrees on Sunday is going to be a challenge. Temps in the 40s in mid-May is cruel and unusual punishment, but that's what's on tap for the weekend.

Really, the cool temperatures are the result of a powerful storm system that features a warm front that'll be draped somewhere near the Iowa border. Temps north of the front are colder while much warmer conditions – and potential for severe thunderstorms – exist south of the front. 

So while it'll barely reach 50 in the metro Saturday, the temp in Mankato and Rochester will inch close to 70 while the mercury could reach close to 80 near the Iowa border. And that's where there's a slight risk for severe storms.

Large hail is possible with storms as far north as the Twin Cities and St. Cloud, but the chances are slim. 

According to the National Weather Service, it'll be cold enough on Sunday that there could be snow mixing with rain along and east of the Interstate 35 corridor north of the Twin Cities. You can see some blue show up in the simulated future radar (may not work in all browsers) and that's an indication of snow.

Accumulations are not expected, but for gee gosh golly this is ridiculous. Last year on May 18-19, the high temps in the metro reached 84 and 72, respectively. Fortunately, the cool pattern will be gone by midweek with 70s returning by Wednesday.
