DISCUSSION

Issued at 301 PM CST Sun Nov 8 2026

An area of low pressure was located between Lake Superior and James Bay this afternoon with a cold front trailing into northern Lower Michigan and northern Illinois. High pressure was located over the Plains setting up a pressure gradient across the Northland. This gradient was leading to winds gusting to 20 to 30 mph across the region. Heading into tonight, a ridge axis will move through the Upper Midwest with winds quickly becoming light and variable after sunset. Clouds will spread across the area overnight and keep lows slightly warmer than previously forecast in the middle to upper 30s.

Dry conditions will then prevail for Monday and Tuesday. A cold front will move through Monday afternoon into Monday evening, but is expected to be a dry passage with most of the energy with the system lagging behind the front. Highs Monday will be in the 50s before cooling into the middle 40s to middle 50s on Tuesday behind the front.

Our next chance of precipitation will be seen late Tuesday night into Wednesday as an upper trough swings through the Upper Midwest. This will be accompanied by a midlevel lobe of vorticity and low pressure. With not much of a surface reflection and limited moisture, overall precipitation chances are low across the region. The exception will be across the South Shore with lake-effect rain and snow showers thanks to 850 temps of -5 to -10C and Lake Superior temps in the 40s F. Mainly rain showers are expected for Wednesday before mixing with and changing to snow showers overnight and lingering for Thursday and Thursday night before drier air arrives and turns off the lake-effect. Any snow accumulations look to be minimal and limited to the northwest Wisconsin snowbelt from Ashland County into Iron County. Cooler air arrives for the latter half of the week with highs only in the 30s for Thursday and Friday. High pressure will then lead to dry conditions heading into the weekend with temperatures warming back into the 40s by Sunday.

AVIATION /00Z TAFS THROUGH 00Z TUESDAY/

Issued at 546 PM CST Sun Nov 8 2026

VFR conditions are expected through the period. Winds will be light and variable. A few models hinted at a possibility of mist or fog development early Monday morning. Think the potential is relatively low at this time since high clouds and light southerly winds will limit cooling tonight. A southwesterly low- level jet is forecast tonight ahead of a cool front approaching from the west. Included LLWS for INL and BRD. May need to add it to HIB, DLH, and HYR with later updates. Another period of LLWS is possible Monday afternoon and evening due to strong northwest winds aloft.

Issued at 301 PM CST Sun Nov 8 2026

Breezy northwesterly winds this afternoon will diminish quickly after sunset as weak high pressure moves in. Winds will become southwesterly tomorrow morning at 10 to 20 knots with a few higher gusts to around 22 knots along the northern Bayfield Peninsula. A weak cold front will move through late Monday afternoon into Monday evening and turn winds northwesterly at 10 to 15 knots with gusts to 20 to 25 knots along the North Shore. Stronger gusts to 30 knots will be possible from Taconite Harbor to Grand Portage. Small Craft Advisories will likely be needed along much of the North Shore. Winds then become southwesterly for Tuesday at 10 to 15 knots and northerly Tuesday night at 5 to 10 knots.
