KEY MESSAGES

- Benign weather with cooler than normal temperatures expected the rest of this week.

DISCUSSION

Issued at 216 AM EDT Tue May 5 2026

Expect fairly quiet weather over the next several days as troughing remains over the area and the jet stream remains to the south of us for the next week. While multiple weak shortwaves look to roll through the region and could potentially bring some light rain (and snow on Wednesday) showers at times, dry air at and just above the sfc looks to limit precipitation amounts seen over the next week. With high pressure ridging being seen over the PacNW the rest of this week before slowly progging eastward early next week, expect cooler Canadian air to generally move into the U.P. throughout the forecast period; thus, below normal temperatures are projected for today into early next week as highs typically only get into the 40s and 50s and lows drop into the 20s and 30s.

With the dry conditions expected at the sfc the next several days, expect mixing in the boundary layer to induce dry RHs on the ground. Therefore, don't be surprised if we see several days at a time where RHs get below 30% over portions or even much of the U.P., with the south central expected to get into the 20 percents RH this afternoon. The days where this may be an exception are possibly on Wednesday when rain and snow showers are possible and potentially when rain showers occur this weekend and beyond with the passage of some weak shortwave lows. Yet, because temperatures are still expected to be below normal for this next week or so, no elevated fire weather conditions are predicted, although we may approach it today as winds remain gusty from the west (gusts generally 20 to 30 mph).

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1229 AM EDT Tue May 5 2026

VFR conditions prevail through the TAF period. A broad trough over the Great Lakes will continue to bring colder air into the region and maintain gusty northwesterly winds. As cold air aloft strengthens today a few very light rain or snow showers can't be ruled out but not expecting any impactful vsby or cig restrictions. Expect winds to diminish during the evening as the pressure gradient relaxes and mixing ceases.

MARINE

Issued at 216 AM EDT Tue May 5 2026

West to northwest winds of 20 to 30 knots continues today as cold air advection pumps into the Upper Great Lakes. However, winds drop down to 20 knots or less tonight as weak high pressure ridging begins to build back into the area. Expect the light winds to continue through the rest of the week as weak ridging and troughing oscillates over the area.
