A few showers possible Sunday; strong to severe t-storms possible Monday night

A cold front will move southeast across the Northland Sunday afternoon into Sunday night with a chance of a few showers as that front moves through.

A risk of strong to severe thunderstorms returns to the Northland Monday night.

An elevated mixed layer will be in place Monday over the Western High Plains with hot and dry conditions. Strong southerly flow ahead of this EML will help push higher amounts of (CAPE) instability and moisture E-NE into the upper Midwest Monday night which could lead to the development of strong to severe thunderstorms in parts of the Northland.

High temperature forecast for Sunday, September 1

…Weather Summary…

A very pleasant end to August with scattered clouds, light winds and high temps which were close to normal, ranging from the mid 60s to lower 70s.

Southerly winds on Sunday will draw a little more moisture into the area with dew points climbing into the mid 50s to around 60 degrees. Some lift associated with a southeastward moving cold front combined with the increase in low level moisture will cause a few showers in the Northland on Sunday into Sunday night. Note: Not expecting widespread heavy rain Sunday, only a few showers with many dry hours still expected. Highs Sunday should be quite similar to what we saw on Saturday with highs in the mid 60s to low 70s.

Looks dry during the day Monday, then will see shower and thunderstorm chances ramp up Monday night into Tuesday morning as a deepening low along with a warm front and cold front move across the upper Midwest.

High temperature forecast for Thursday, August 29

…Weather Summary…

Deep low pressure of around 994mb was over northern Ontario this afternoon with a tight pressure gradient still in place over the upper Midwest today because of the difference in pressure between the low to the north and high pressure across the Central Plains. West winds have been gusting to around 30 mph across the Northland today.

The last of the clouds associated with the Ontario low are moving out of the Arrowhead as of 5 PM Wednesday with mainly clear skies covering the Northland late this afternoon as widespread clouds from earlier in the day pushed off to the east.

Quick changes in the weather will take place through Thursday as a cold front pushes southeast through the area. Ahead of this front a brief surge of warm air advection will send 850mb temperatures to around +10 to +15C early Thursday morning, but once the cold front moves through will have another shot of cold air advection which will drop the 850mb temperatures to +5 to +10C during the afternoon.

There will be some weak CAPE (instability) that builds northeast into the area along with steepening mid level lapse rates, this combined with a SW low level jet of 30 to 50 knots will likely lead to some shower and isolated thunderstorm development in the Northland as a cold front moves through during the morning hours.

Looks mainly dry Thursday afternoon, although a pop-up shower is possible as colder air aloft moves in with H5 temps falling to around -20C.

Wind will be an issue once again Thursday as southwest winds shift to the northwest with gusts 20 to 30 mph.

Lows tonight will mainly be in the 50s, but a few 40s are possible in the typical cool spots. Highs Thursday in the mid 60s to mid 70s (warmest temps in northwest Wisconsin and eastern Minnesota)

Note: Looks mainly dry Friday and Saturday but we could be dealing with some scattered showers in parts of the Nortland Sunday and Labor Day (Monday) with the greatest chance of rain coming on Labor Day the way it looks now.

Forecast for Duluth and Superior

.Tonight… Breezy. Clear this evening. Partly to mostly cloudy overnight. Scattered showers and possibly a thunderstorm mainly after 3 AM. Low 52 to 57. Wind west 15 to 25 mph becoming southwest 10 to 20 mph.

High temperature forecast for Wednesday, August 28.

…Weather Summary…

A strong area of low pressure (~990mb) was over northern Ontario this Tuesday afternoon. This low won’t move very much as it moves over Hudson Bay the next few days. A tight pressure gradient between the low to our north and high pressure to our south will continue to produce gusty west winds through Wednesday with wind speeds of 10 to 20 mph with gusts to 35 mph.

Cold air advection continues tonight with 850mb temperatures falling to around +3C by Wednesday morning, this will be replaced by a strong push of warm air advection early Thursday morning as 850mb temperatures climb to around +10 to +18C, this won’t last very long, however, as another shot of cold air advection pours into the Northland during the day Thursday although not quite as intense as what we have tonight.

With the changing temperatures, wind will be an issue the next few days, just another sign that fall is approaching.

Lows tonight will range from the middle 40s to middle 50s with highs Wednesday in the lower 60s in far northeast Minnesota to the middle 60s to around 70 degrees elsewhere.

Mostly cloudy skies tonight with some light rain and drizzle which could linger a few hours past sunrise Wednesday, then will see increasing amounts of sun by Wednesday afternoon.

A cold front moves quickly through the Northland Thursday morning, we could see a few showers or thunderstorms develop as that front moves through. Instability doesn’t look very impressive with CAPE on the low side, but the mid level lapse rates steepen quite a bit, possibly in the 7.0-8.0 c/km range so we could see a few thunderstorms develop in parts of the area roughly in the 2 AM to 11 AM time frame on Thursday.

Dry weather is expected Thursday afternoon into Friday.


Forecast for Duluth and Superior

.Tonight… Breezy. Mostly cloudy. Some light rain or drizzle possible. Low 48 to 53. Wind west 15 to 25 mph.

.Wednesday… Breezy. Mostly cloudy early with some drizzle possible followed by mostly sunny skies in the afternoon. High 65 to 70. Wind west 15 to 30 mph.

.Thursday… Breezy. Isolated showers or thunderstorms possible before 10 AM, otherwise partly cloudy. High 68 to 73. Wind southwest 15 to 25 mph early, becoming northwest.

Steady rain ends from SW-NE this evening with spotty showers the rest of tonight. Then with some heating on Tuesday will see showers become more widespread during the day.

Another sign we’re heading into fall are quick changes in temperatures, instead of being in a stagnant pattern for what seems like weeks at a time (summer months) we tend to see more frequent changes in temperatures during the fall months. This will be the case Wednesday into Thursday with strong cold air advection Wednesday dropping 850mb temperatures to around +2C, but this will be replaced by a strong push of warm air advection Thursday morning which will boost the 850mb temperature to around +15C, but this also won’t last long as a cold front pushes SE through the Northland Thursday afternoon with some cold air advection taking place behind this front Thursday night.

High temperature forecast for Tuesday, August 27.

…Weather Summary…

A steady band of rain will continue to lift north/east while it affects northeast Minnesota and northwest Wisconsin tonight, this area of rain will diminish from SW-NE this evening and will be followed by a few showers and isolated thunderstorms overnight.

Surface and upper level areas of low pressure will deepen through Wednesday as they move slowly through Ontario. One or two troughs will rotate around this system, and those troughs will affect our weather through Wednesday morning.

Expect scattered showers along with a few thunderstorms Tuesday followed by some drizzle and light rain Tuesday night into Wednesday morning.

This system pulls far enough away from our area by Wednesday afternoon with nicer weather returning at that time.

With the low deepening to our north and high pressure setting up from the Northern Rockies to Central Plains will see the pressure gradient tighten which will lead to gusty westerly winds in the Northland through Wednesday. Winds of 10 to 20 mph are likely with gusts approaching 35 mph.

Lows tonight will mainly be in the 50s with highs Tuesday ranging from around 60 to 70 degrees.

Wet weather the next few days; windy and cool Tuesday-Wednesday

The final week of meteorological summer 2019 will be rainy at times, especially the period from Monday through Wednesday. Note: Going into today (August 25) Duluth is around -1.40″ below normal in rainfall for the month, and since June 1 we’re around -2.75″ below normal.

The first of what should be a few rounds of rain to affect the Northland in the coming days is moving northeast out of central Minnesota late this Sunday afternoon. Note: Reminder that Duluth’s radar (KDLH) is out of service until later this week as a major system upgrade continues. Alternate radar sites are Grand Forks (KMVX) or Minneapolis (KMPX)

Much of the Northland could get 1 to 2 inches of rain by Wednesday morning with isolated totals of more than 3 inches possible.

An impressive shot of cold air advection is possible late Tuesday into Wednesday. I believe this is the first time since last spring where we have blue colors showing up on the 850mb temperature map, another sign that fall is approaching. Note: You start thinking about snow when the 850mb temp falls to 0C, but we won’t be seeing any snow this week as the surface temps are just too warm to produce anything other than rain.

Wednesday looks like the chilliest day of the week with potential for daytime highs struggling to hit 50 degrees in the Arrowhead and Borderland areas. Might struggle to hit 60 degrees in Duluth. Note: Normal highs in late August are still in the lower 70s.


Note: The average temperature last week at Duluth, Minnesota was below normal for the first time in 8 weeks! You have to go back to the week of June 16 to find the last time where Duluth’s average temperature for a 7-day period was below normal.

The list below shows the average temp and departure from normal for the weeks from June 16 through August 18.

High temperature forecast for Monday, August 26

…Weather Summary…

A strong storm system (autumn like) will be impacting the Northland through midweek.

Energy to our northwest and southwest this afternoon will attempt to phase a bit during the next 24-36 hours, how much phasing occurs is still a bit uncertain, but there is potential for a deep surface low to develop by Tuesday with a central pressure down to around 985mb just northwest of Lake Superior. Note: Gale force wind gusts out of the west/northwest are possible over western Lake Superior from Tuesday into Wednesday if this system deepens enough.

As this system intensifies winds will increase out of the west by late Monday night or Tuesday with wind gusts of 20 to around 35 mph possible across much of the Northland on Tuesday, which could linger into Wednesday.

Cold air advection will also occur on the backside of this system with 850mb temperatures of +1 to +5C spilling into the Northland for Tuesday and Wednesday.

Low level moisture will continue to increase ahead of this system tonight thanks to a southerly flow with precipitable water of around 1.30 to 1.60 inches building into the Northland — Better forcing with the approach of a cold front will cause rain to become more widespread in our area tonight into Monday night with some breaks likely to occur in between the waves of precipitation. We could also see a few thunderstorms develop in the Northland along a cold front Monday afternoon-evening, but instability looks fairly limited due to the expected cloud cover and precipitation.

Lows tonight will be on the mild side because of the clouds, lows will be in the mid 50s to low 60s. Highs Monday in the 60s in northern Minnesota with low to mid 70s in northwest Wisconsin and far eastern Minnesota.

Occasional showers will continue Tuesday and Wednesday as moisture wraps around a low pressure system which will be off to our north.

Will dry out late this week, although there will be another cold front moving through the area Thursday, but right now this front looks to come through on the dry side.


Forecast for Duluth and Superior

.Tonight… Occasional showers developing. Mostly cloudy. Low 57 to 62. Wind south to southeast 10 to 20 mph.

.Monday… Occasional rain (dry hours mixed in) Mostly cloudy. High 66 to 71. Wind east to southeast 10 to 20 mph.
