Comfortable weekend temps and dew points

Let’s take a walk through the weekend.

Most of our weekend hours will be dry, but a few scattered showers are possible in central and southern Minnesota late Friday evening into Saturday morning. The National Oceanic and Atmospheric Administration’s North American Mesoscale (NAM) forecast model shows the potential rain pattern Friday evening through Saturday afternoon:

The NAM model also shows scattered showers in south-central Minnesota Saturday afternoon, while other models do not.

You can hear updated weather information on the MPR network, and you’ll see updated weather info on the MPR News live weather blog.

Saturday highs are in the 70s in many areas, with a few 80s in southwestern Minnesota and some 60s northeast:

Temps ramp up next week

The Twin Cities metro area will see highs in the upper 80s next Monday, followed by lower 90s Tuesday and possibly mid-90s on Wednesday.

The European Center for Medium-Range Weather Forecasts (ECMWF) model shows temps in the 90s in much of the southern half of Minnesota at 1 p.m. next Tuesday:

Our highs this time of year often occur around 4 p.m., so Tuesday highs will probably exceed those 1 p.m. temps.

The European forecast model also shows many 90s at 1 p.m. on Wednesday:

Dew points in the sticky 60s are expected in the hottest areas on Tuesday and Wednesday, so it’ll feel summery.
