Windy weather on the way for Halloween with a few rain showers during the day, snow showers at night; much warmer next week (60 degrees?)

Milder but breezy conditions are expected on Halloween (during the day) but this will be replaced with colder temperatures and strong winds for Halloween night all thanks to a strong area of low pressure which passes by to our north on Saturday. Note: Gale and Storm Watches have been issued for portions of Lake Superior for Saturday into Sunday with a west to northwest gale event possible. This will be an offshore wind direction so the largest waves will be east of the Twin Ports and North Shore this weekend.

A shot of warmer air on southwesterly winds will occur ahead of this system on Saturday, and then will see winds shift to the northwest which will usher in a colder air mass Saturday night.

Highs on Saturday are expected to be in 40s, but a few locations may get into the lower 50s! Winds will be out of the southwest at 10 to 20 mph with gusts >30 mph.

Lows Saturday night will be in the 10s and 20s with winds shifting to the northwest at 15 to 30 mph with gusts >40 mph.

Note: Not looking at a whole lot of rain on Saturday, just a few passing showers. As for snowfall totals, not much, maybe up to an inch of snow Saturday night across northern Minnesota, but higher totals of 1 to 4 inches are possible late Saturday night into Sunday morning due to some lake effect snow along the South Shore of Lake Superior mainly around the Gile, Upson and Hurley areas west toward Mellen.

Our system for Saturday is a strong one, a lot of energy with it, but not much moisture so precipitation should remain light and spotty as this system moves across the Northland.

A brief surge of warmer air currently over the Northern Rockies and the Northern Plains this Friday afternoon will move quickly east and over the Northland Saturday morning, and then will see another brief surge of cold air move in Saturday night into Sunday.
