Peak fall color up north, rain returns Sunday

Fall color burst up north

This might just be the best weekend for leaf peepers in northern Minnesota. Fall color is at or near peak in many spots up north. There's still plenty of green in southern Minnesota with a few splashes of color.

Warmer by the lake?

Say what? It's usually "cooler by the lake." But this time of year water temperatures in Lake Superior are much warmer than surrounding land areas at night. That produces a protective blanket of warmth in nearshore areas. Water temperatures are still pushing 60 degrees around Two Harbors.

Sunday showers

High pressure keeps us sunny and dry through Saturday.

I'm optimistic we may just squeak in a favorably cool and dry Twin Cities Marathon Sunday morning. Most of the forecast models attempt to hold off rain until at least midday Sunday. Showers expand eastward Sunday afternoon.

Wet next week

Low pressure waves move along a stalled front next week. That sets up several waves of rain. We could see some soaking rainfall totals next week. Here's NOAA's GFS model rainfall output through next Wednesday.
