Area Forecast Discussion National Weather Service Duluth MN 615 AM CDT Wed Sep 11 2024
KEY MESSAGES
- Hazy skies and warm temperatures the next couple days
- Possible rain chances this weekend (20-30%)
DISCUSSION
Issued at 325 AM CDT Wed Sep 11 2024
Current Conditions/Today:
A stalled out boundary cuts through Northern MN this morning and is expected to linger through the day. Ridging aloft and dry air over the region will lead to a quiet weather day. Large quantities of wildfire smoke continue to pour in from the west which will lead to hazy skies through the day. Look for highs to climb into the low and mid 80s.
Tonight/Tomorrow:
Warm air advection ramps back up overnight with southerly flow streaming into the region. This may lead to fog forming once again.
The rest of the day will be similar to what we'll see today. Warming afternoon temps into the 80s with hazy skies aloft.
Weekend:
Our next pattern change looks to arrive this weekend. The NBM still seems to be oscillating with 20-30% PoPs this weekend, but the signal is consistently there. The overall conundrum is how an upper level trough that digs in across the Intermountain West will interact with the Rex Block expected to set up over the Great Lakes region thanks to Hurricane Francine. Some ensembles favor the upper level trough weakening and being deflected north of the region. Another possible scenario is remnant moisture from the Hurricane advects north through NW WI. Overall we likely won't get a good grasp on the pattern until both features move onshore later this evening.
AVIATION /12Z TAFS THROUGH 12Z THURSDAY/
Issued at 615 AM CDT Wed Sep 11 2024
Lingering fog this morning is expected to erode by mid morning.
The rest of the day will be VFR with hazy skies and light winds. Overnight there will once again be a chance for fog to form impacting many of the terminals across the Northland.
MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/
Issued at 325 AM CDT Wed Sep 11 2024
Light southerly winds today becoming northeast overnight. Speeds increase on Thursday. Currently carrying some gusts of 20 kts at the head of the Lake but funneling could warrant advisories for small vessels.
