KEY MESSAGES

- Quiet weather with seasonable temperatures to kick off this work week

- Shower/storm chances return Tuesday night into Wednesday

- Typical summer weather to end the period

DISCUSSION

Issued at 230 PM EDT Sun Aug 2 2026

Pattern Synopsis/Forecast:

Shortwave troughing continues to exit slowly off to the east, taking corridor of forcing and deep layer moisture convergence east along with it. Large area of Canada originated high pressure building south into the northern Lakes, with attendant aggressive deep layer drying and subsidence bringing mostly sunny skies to areas north of the big bridge, and helping scatter out some of the overcast across northern lower. While nothing too extreme, system backside northeast winds ushering in a seasonably chilly airmass across the Northwoods, with current readings mostly in the lower to middle 70s.

Shortwave troughing will continue to exit off to our east, replaced by rather stout mid level ridging and its attendant surface reflection to kick off this work week. Central NOAM upper level flow regime does remain somewhat progressive, with next wave and cold front to visit the area the middle of this week. Deterministic guidance and a vast majority of their ensemble suite still support broad troughing dominating northern Great Lakes weather to end the week on into the start of the weekend, with at least some support for a more zonal flavor to the upper level flow regime developing toward the end of this forecast period.

Primary Forecast Concerns:

Temperature trends through the period and addressing periodic rain chances...especially those on Wednesday.

Details:

Really not a whole lot to discuss into Tuesday as vertically stacked high pressure controls our weather. Skies continue to become mostly clear tonight, and with some lingering low level moisture and winds becoming light/calm, will likely allow some patchy fog to develop... especially in more open areas and over/near inland bodies of water. Temperatures tonight will remain a bit chilly, with some of our traditional colder interior areas likely making a run into the mid and upper 40s. Just about ideal early August weather for Monday and Tuesday, with sun-filled skies and mild to warm weather. Simple airmass modification will help temperatures Monday reach near normal levels in the upper 70s to lower 80s. Developing return flow, coupled with that sunshine, will help tack on a few more degrees for highs on Tuesday...when widespread afternoon temperatures in the lower to middle 80s are expected.

Weather turns a bit more active Tuesday night and especially Wednesday as shortwave troughing and its attendant cold front work into and through the area...both collocated nicely with rather impressive right entrance region upper jet dynamics. Expect at least a broken line(s) of convection to attend this wave, with potential for some diurnally-driven instability support Wednesday afternoon helping both coverage and intensity of showers/storms (dependent on still highly uncertain timing of course). Not tentatively seeing any real support for any significant severe weather or heavy rain threat, although cannot completely rule out a stronger storm or two with isolated pockets of heavy rain given modest convective depth wind shear and precipitable water values up and over an inch and a half. Weather Prediction Center does highlight marginal risk wording for excessive rains on Wednesday, specifically mentioning those impressive jet dynamics. Plenty of time to work those details out in the coming days.

Rest of the week currently looks rather uneventful, although suppose a few showers are possible at times with any passing hard to time waves within that broad overhead troughing. Temperatures will fall well within the range of what is considered normal as we head into the second week of August.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 621 AM EDT Sun Aug 2 2026

The last of the MVFR CIGs at APN will be exiting shortly, with VFR conditions expected through the period and clearing skies. Breezy northeast winds to continue through the rest of this afternoon, 10G18-20KTs on average, decreasing tonight. Fog potential at terminals appears quite low, and patchy in nature, thus no inclusion at this time. Clear and VFR on Monday with light north to northwest winds.
