Some sun at times, with a shower or thunderstorm possible

If you ask a meteorologist whether you'll need your sunglasses or your umbrella this weekend, they'll probably say "yes".

We'll have some periods of sun or a sun/cloud mix, but scattered showers and a few thunderstorms are possible both days, mainly during the afternoon and evening hours.

The Storm Prediction Center of the National Weather Service indicates the potential for general thunderstorms, not severe weather, over Minnesota and Wisconsin this Saturday and Saturday night:

Our Saturday highs should reach the 70s statewide, with similar highs on Sunday:

The week ahead

There isn't any big warmup in sight.

Temperatures are likely to run slightly below average over much of Minnesota this coming week.

Twin Cities high temps will be around 80 Monday and Tuesday, with upper 70s Wednesday through Friday.

The best chance of rain this week will be Wednesday into Thursday.

The National Oceanic and Atmospheric Administration’s Global Forecast System model shows the potential rain pattern:

August 21 eclipse

There's already a lot of buzz about the total solar eclipse that will be viewable in parts of the U.S. on August 21:

The darkest blue band shows the areas that will see a total solar eclipse.

It  won't be a total solar eclipse in Minnesota, but a 75% eclipse is also impressive!

As we get closer to August 21, the NWS Solar Eclipse page will be a good source of viewing information.

NASA has posted some guidelines for safe viewing of the solar eclipse.
