DISCUSSION

Diurnal showers and storms should dissipate quickly early this evening with the loss of daytime heating and as forcing diminishes. I would expect most of the activity through late afternoon focused from Saginaw Bay northwest into northeast lower, within a deeper moisture axis and with enhancement from inland penetrating lake breeze boundaries. Stronger storms could produce small hail and brief, heavy rain. Skies clear with light winds tonight, allowing temperatures to fall into the 40s over many interior areas. Some patchy fog will also be possible.

Northern Michigan gets squeezed between weather systems on Sunday with an upper low north of Lake Superior and low pressure sliding through the northern Ohio Valley. We will likely see an increase in clouds during the afternoon over southern parts of the area in association with the low tracking well to our south. Lake breezes are also likely during the afternoon under an overall light wind regime, with a few showers possible along these boundaries over eastern upper. Overall, a nice Fathers Day weatherwise across northern Michigan. Sunday night, the storm system sliding to our south may push some showers as far north as our southern border (south of M-55), dry elsewhere.

Quiet weather heading into the new week Monday-Tuesday with a quasi- zonal flow across the northern tier of the CONUS. Unsettled weather and increasing rain chances by later Tuesday extending into the second half of the week, as shortwave energy helps to once again carve out the upper trough across the Great Lakes. Temperatures generally remain below normal through the period. For those wanting some warmer temperatures, there are signals of a push of warmer air into the eastern half of the country for the end of the month into early July as troughing develops over the Pacific Northwest and inter-mountain west, inducing ridging over the central/eastern parts of the CONUS.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 702 PM EDT Sat Jun 20 2026

Only concern is the possible development of MVFR to even IFR producing stratus and mist/fog at KCIU and KMBL early Sunday morning...with the greatest confidence of this occurring at KMBL. Looking at VFR conditions tonight elsewhere under mostly clear skies. Any low clouds/fog/mist will erode quickly after sunrise Sunday, leaving behind VFR conditions across the taf locations under some higher based cumulus. Light winds through the period with local afternoon lake breeze development expected.
