March 20, 2016 Weather Report - Around 40 degrees on Monday; Around 1" of slop Monday night which could lead to mass chaos Tuesday morning

/Issued 5:09 PM CDT, Sunday, March 20, 2016/

Not much change in this map from Saturday -- Still expecting this storm during the middle of the week to miss Duluth and Superior.  As for snow totals down south, potential is certainly there for several inches of snow, maybe as much as 6-10" in the blue outlined area on the map.

Another week that was warmer than average in Northeast Minnesota and Northwest Wisconsin.  Here's last week's temperature departure map.

A ton of precipitation with that storm last week which led to the week being 1-2"+ above average in most of Northeast Minnesota and all of Northwest Wisconsin.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  Medium to High.

Tonight (March 20)

Mainly quiet under a partly to mostly cloudy sky.  Could be a few flurries or snow showers in far Northeast Minnesota and in far Northern Wisconsin but most of us will remain dry.  Lows will be in the 20s to around 30 degrees with teens and possibly a few single digits in far Northern Minnesota.  Winds will shift from the northwest to a southerly direction later in the night.

Monday and Monday night (March 21)

Partly to mostly cloudy skies for Monday with highs in the 30s and 40s, winds will be out of the south at 10 to 20 mph -- A weak cold front will continue to pass through the Northland tomorrow morning and should move into Southern Minnesota by tomorrow night...A band of light snow and mixed precipitation is forecast to develop tomorrow night in our area to the north of that frontal boundary.  Lows Monday night will be in the 20s and 30s with winds shifting to the east at 10 to 20 mph.

Note:  Snowfall accumulations of around 1-2" are possible Monday night especially along and north of Highway 2.

Extended Forecast - Confidence:  Medium to High.

Tuesday through Thursday (March 22-24)

Lingering snow or rain showers are possible on Tuesday with highs in the 30s and 40s, lows Tuesday night will be in the teens and 20s.  The main weather story for Wednesday and Thursday will be an area of low pressure which tracks from the Central Plains toward the Southern Great Lakes/Ohio Valley region -- Several inches of snow and gusty winds are possible north of this system in Southern Minnesota into portions of Iowa and Wisconsin.  

Note:  This storm should remain far enough south of the Northland to give us any snow during the middle of the week.

High temperatures on Wednesday and Thursday will be in the 20s and 30s with lows Wednesday night in the teens and 20s.

Gusty east or northeast winds could affect areas near Lake Superior from Tuesday into Thursday morning due to a tightening pressure gradient between low pressure to our south and high pressure to our north; Wind gusts of 25-30+ mph could develop during the aforementioned time frame.

Long Range Forecast - Confidence:  Medium to High.

(March 25-30)

Below to near normal temperatures during the long range.  A chance for some snow or rain on the 25th-26th and possibly again sometime during the 28th-30th time frame.  No major storms are expected to affect the Northland though the way it looks now.
