.SHORT TERM /THROUGH TONIGHT/...

Issued at 312 PM EDT Thu Jun 26 2025



Pattern Synopsis:



Short-lived ridging will slide east of the Great Lakes tonight as a 

relatively weak shortwave punches overhead. This feature will 

provide sufficient support aloft for a surface cyclone ~1010mb to 

trek across the region tonight and Friday. A warm front gradually 

working north downstate will struggle to make it past the CWA border 

this afternoon, eventually surging north across the area later 

tonight into Friday as the aforementioned system tracks through.



Forecast Details:



An isolated strong storm will be possible along and south of M-55 

later this afternoon/evening with the primary hazards being damaging 

winds, small hail, and frequent lightning. Otherwise, much more 

widespread showers and storms will work across the area later 

tonight through Friday morning. Mostly likely timing for storms will 

be from midnight to 10 AM Friday, beginning and ending from west to 

east across northern Michigan. A few strong storms can't be ruled 

out overnight with marginal elevated instability and shear in place, 

but severe storms are not currently expected overnight into Friday 

morning. The primary concern with showers and storms overnight will 

be the potential for locally heavy rainfall. PWAT values around 1.6" 

to 1.8" approach climatological daily max values, allowing for very 

efficient rainfall with activity tonight. Rainfall amounts of 1-2"+ 

will be possible by Friday morning across the eastern U.P. and Tip 

of the Mitt where most persistent showers and storms are 

anticipated, with lesser amounts around 0.5-1" for areas further 

south. While overnight activity should move east of the area by 

noon, a few additional storms may pop up across northeast lower 

during the afternoon. Otherwise, rain-free weather is expected 

across northern Michigan through the remainder of the day. 

Temperatures in the 70s and 80s are in store, with those near 

Saginaw Bay potentially warming into the upper 80s during the 

afternoon.

.LONG TERM /FRIDAY THROUGH THURSDAY/...

Issued at 312 PM EDT Thu Jun 26 2025



Pattern Synopsis:



Weak zonal flow looks to set up for the first half of the weekend, 

contributing to a nebulous surface pattern across the the region. 

Troughing will encroach on the Great Lakes heading into Monday, 

providing forcing aloft to generate surface pressure falls along a 

diffuse cold front that looks to gradually work across the region 

during the first half of next week as the parent cyclone treks to 

our north. Behind this, high pressure looks to build into much of 

the Midwest through the remainder of the period.



Forecast Details:



Pleasant weather is in store for the Northwoods to kick off the 

weekend with rain-free weather expected and highs in the 70s and low 

80s under partly to mostly sunny skies. Temperatures will continue 

to warm on Sunday as highs look to climb well into the 80s -- and 

even approach 90 across interior areas. Chances for showers and 

storms returns to the area late Sunday as the aforementioned front 

works into the region. Given ample instability and at least some 

deep-layer shear to work with, a strong storm or two cannot be ruled 

out. Rain chances will continue at times through the first half of 

the week with the middle of the week currently expected to be dry as 

high pressure builds in.

.AVIATION /18Z TAFS THROUGH 18Z FRIDAY/...

Issued at 128 PM EDT Thu Jun 262025



Showers have largely diminished across the Northwoods with 

cloudy skies expected to persist through the rest of today with 

a continued mix of VFR to IFR conditions. Clouds will generally 

increase again late tonight ahead of a developing area of 

showers/ storms expected ~04Z through early Friday. Ceilings and

visibility look to lower to MVFR to IFR in heavier showers/ 

storms during that time. East winds will decrease through the 

night and shift southwest Friday morning with occasional gusts 

10-15 kts-- with the exception of areas near the tip of the Mitt

and north where occasional gusts 20-25 knots are possible 

through tonight (PLN and CIU). Some low-level wind shear may 

develop overnight into early Friday as stronger winds aloft move

into the region.
