Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
A chilly start to the day with widespread 20s and even some teens in our area, some of the colder lows This Morning include: Hayward, WI: 21 degrees. Silver Bay, MN: 19 degrees. Grand Marais, MN: 19 degrees. Superior, WI: 21 degrees. Embarrass, MN: 16 degrees. An area of low pressure was centered to our north This Afternoon with a trough attached to this low passing through the Northland This Morning and early This Afternoon. This system brought a few showers to our area Today with some snow and sleet mixed in with the rain in some spots. The precipitation associated with this frontal boundary exited to our east by early Afternoon, then we saw some instability showers develop during the Afternoon due to cold air aloft (-34 degree C 500mb temps) and some milder temps at the surface, this combined with steep lapse rates approaching 9.0 c/km, CAPE around 200 j/kg and Lifted Indices close to zero degrees C resulted in these popcorn type showers that developed in Northeast Minnesota and Northwest Wisconsin This Afternoon. High temperatures Today were in the middle 40s to lower 50s south of Highway 2 and in the mid 30s to low 40s in Northern Minnesota into the Arrowhead. Winds Today were out of the northwest or southwest at 5 to 15 mph with some higher gusts.
Today’s Upper Level Analysis:
Northwest 500mb flow was in place across the Upper Midwest with an upper level low churning southeast out of Southern Ontario Province per water vapor satellite imagery. This system is associated with 30-60 meter 12 hour 500mb height falls Today across the Upper Midwest per RUC model analysis.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Tonight:
Surface and upper level low will remain to our north/east. Scattered showers of rain, snow and sleet will taper off This Evening. A few spots up north could pick up a light dusting of snow in the most vigorous showers during the Evening. Looks dry Overnight with skies becoming partly cloudy. Lows will be in the 20s and 30s with some teens possible in the traditional cold spots. Winds will be out of the northwest or west under 20 mph.
Saturday and Saturday Night:
Dry weather is forecasted Tomorrow with partly cloudy to sunny skies. Temps will be close to average with highs in the 40s to around 50 degrees. Winds will be out of the south or west under 15 mph. Clouds will be on the increase Saturday Night as low pressure heads toward the Northern Plains. Some light rain or mixed rain and snow could move into Western-Southwest parts of our area, including the Cass Lake, Walker, Brainerd and Aitkin areas. Low temperatures Tomorrow Night will be in the 20s and 30s with winds becoming east at 5 to 15 mph.
Extended Forecast:
Low pressure will pass south/east of our area from Sunday into early Monday. Some light rain is possible on Sunday for Eastcentral Minnesota and Northwest Wisconsin, some of the rain could mix with snow especially early in the day. Most if not all of the precipitation on Sunday is expected to remain south of Highway 2 based on lasted model projections. Dry weather returns to Northern Minnesota and Northwest Wisconsin from Sunday Night into Monday Night. Highs on Sunday will be mainly in the 40s with lows Sunday Night in the 20s and 30s. Highs for Halloween will be in the 40s and 50s with lows Monday Night mainly in the 30s.
Not much going on for next week…Cold front will push southeast across the Upper Midwest during the Tuesday-Wednesday time frame, any meaningful rainfall should remain south of our area near the deeper moisture and near a possible low pressure wave that may form and move along this front. Could be a system for next weekend (November 4th-7th) time frame, but there is considerable spread on the track, timing and intensity of this potential low per long range computer models.
Note: Rainfall totals in Eastcentral Minnesota and Northwest Wisconsin are expected to remain under 0.10″ for Saturday Night and Sunday with little or no accumulation of snow expected at this time.
