Temperature surge; Sunday thunder

Our minutes of daylight increase nicely as we go through April.

April in Minnesota can also bring us some impressive temperature swings.

The official Twin Cities high temperature was 56 degrees on Wednesday and Thursday, and we'll see rising high temps the next couple of days.

We should see highs in the 60s in the Twin Cities metro area and much of Minnesota this Friday afternoon, with some 50s in northeastern Minnesota.

The warming trend doesn't stop there. Temps take another jump on Saturday.

Highs in the 70s will be common over much of Minnesota Saturday afternoon:

Temps fall back a bit on Sunday in southern and central Minnesota, with highs in the 60s:


Twin Cities metro area highs are expected to be in the mid 50s on Monday, lower 50s Tuesday, then around 60 Wednesday and Thursday.

2016 was our wettest year on record in the Twin Cities, but it's been fairly dry in recent weeks.

Precipitation (rainfall plus the water content of snowfall) is 1.53 inches below normal since March 1 in the Twin Cities metro area.

Sunday severe risk

The Storm Prediction Center of the National Weather Service shows a slight risk of severe thunderstorms Sunday and Sunday night over most of Iowa and a small part of far southern Minnesota:

The remainder of southern Minnesota has a marginal risk of severe weather.

A marginal risk of severe weather means that isolated severe thunderstorms are possible.
