.DISCUSSION...

Issued at 320 PM CDT Sun Mar 22 2026



This afternoon will see the Northland remain cool as high 

pressure builds in from the northwest. While early morning 

flurries have largely tapered off, the cloud cover has been 

persistently draped over all but the Arrowhead region. Skies 

will gradually clear through the remainder of the day and this 

evening, which should allow for some sunshine before dusk for at

least parts of the area. 



High pressure moves across the area on Monday, bringing plenty 

of sunshine and a return to milder temperatures. Southerly winds

will develop by the afternoon, helping highs climb into the mid

to upper 40s. The quiet weather will be brief as a fast- moving

cold front arrives late Monday through early Tuesday morning. 

This system will bring a mix of light rain and snow, though 

accumulations are expected to be minimal.



Confidence is increasing in a more organized weather system for

the middle part of the week. A warm front will advance into the

Upper Midwest on Wednesday, followed by a deepening low 

pressure system on Thursday. This system develops over the high 

plains of NE/SE WY, then moves east across the plains and mid 

Mississippi River Valley through Thursday. A wintry mix of rain,

snow, and freezing rain is likely across much of the region. 

The highest potential for accumulating snow is currently focused

on the tip of the Arrowhead, where chances for 2 or more inches

are in that 40 to 60 percent range. 



Drier but much colder air arrives for Friday and Saturday. A

large high pressure ridge builds into the area, bringing a pool

of cold air from the Northwest Territories into the area. For

now we have stayed close to the NBM forecast, but should we

manage to clear out underneath that ridge for Friday or Saturday

morning, overnight lows below zero are possible. Given the

uncertainty at this point in time that probability is only 30

percent.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...

Issued at 1239 PM CDT Sun Mar 22 2026



Predominantly MVFR conditions remain draped across the

Northland, though they are slowly, slowly sliding south, and I

expect KHIB, KDLH and KINL to break out to VFR by 21z this

afternoon. It will take a little longer for the clearing line to

reach KBRD and KHYR, though have been a bit more optimistic

given the upstream clouds may lift to low end VFR later this

afternoon. A ridge of high pressure to build in this afternoon

and evening, leading to widespread VFR conditions for the

remainder of the terminals once they do clear for the remainder

of the TAF period. Visibilities should remain VFR through the

period, with winds gradually dropping below 10kts this afternoon

and dropping below light and variable after 03z.

.MARINE /FOR NEARSHORE WATERS OF WESTERN LAKE SUPERIOR/...

Issued at 320 PM CDT Sun Mar 22 2026



A Small Craft Advisory is in effect for the South Shore and outer

Apostle Islands until 7 PM this evening. Northeast winds have

already dropped off to less than 15 kts, but waves of 3 to 5

feet are expected to linger for a few more hours. There will be

a period of gusty southwest winds up to 20 kts Monday night, but

these decrease again and turn northerly for Tuesday. Conditions

will be quiet until Wednesday when east to northeast winds

increase and waves build. There may be a need for additional

Small Craft Advisories. 



For the open water discussion, refer to the NWS Marquette Area 

Forecast Discussion at weather.gov/mqt.
