DISCUSSION

Issued at 212 AM EDT Tue Oct 6 2026

Today and Tonight:

Currently, there is broad northwest flow over the Upper Midwest, with energy and subsequent low pressure system across Manitoba. Low level jet is situated across Wisconsin, with generally a lack of meaningful moisture through the column. This will all move eastward through the day, with the leading edge of the low level jet and warm advection potentially producing a few showers across northern lower and eastern upper Michigan. The moisture quality is so poor though that this initial batch of showers will be minor and not a big deal in the slightest.

Low pressure system will move eastward today well to our north across Ontario, with subsequent weak warm front zipping across the eastern UP. Consequently, a renewed chance for showers is expected across the eastern UP this afternoon and evening, with some low end elevated instability. Thus, convection will be possible across eastern upper Michigan this afternoon and evening. Much like the previous night, if a relatively stronger storm were to develop, pea sized hail would not be impossible. Otherwise, perhaps some lightning but this will be a quick moving feature this afternoon.

Pressure gradient will be on the increase today along with increasing winds aloft. Thus, surface winds will increase as well. The winds will increase with time today, peaking late afternoon and evening, spreading from west to east across the area. Thus, the strongest winds will be across northwest lower, especially near the Lake Michigan shoreline. Peak wind gusts 25 to 35 mph this afternoon and evening, higher across the Lake Michigan nearshore and open waters, little lower near Saginaw Bay. Winds steadily decrease later into the overnight hours regardless, with the chance for a few additional showers as well. Worth fine tuning any shower potential tonight with the next cycle.

Wednesday through Thursday:

Deep upper low will dive across Ontario and Quebec Wednesday through Friday, with a few pieces of energy on the southern periphery of this trough. These southern pieces of energy will clip portions of northern MI, especially across the eastern UP. Warm lakes and the cooler temps may aid/promote some of these showers. The deepest piece of energy will move through later Wednesday and Wednesday night, resulting in scattered showers. Cold pool aloft Wednesday night will result in relatively steep mid level lapse rates (small elevated instability) so some low topped convection cannot be ruled out in the vicinity of eastern upper Michigan during this time. Overall though, the mid to latter portions of this week can be described as on and off shower potential, favoring eastern upper and adjacent northern lower, with more dry than wet periods. Temperatures will be within the range of seasonable, a little above Wednesday. Persistent northwest flow aloft and a modest pressure gradient will keep breezy conditions in the forecast each afternoon as well.

This Weekend:

This weekend will feature rising heights aloft and increasing southwesterly winds. Thus, despite breezy conditions, temperatures will rise into the 70s, especially on Sunday. Precipitation chances will be low during this time, but worth monitoring in the coming days.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 607 AM EDT Tue Oct 6 2026

VFR expected through the period. Light, spotty showers this morning will fall from VFR CIGs (~BKN050-100). A renewed chance for -SHRA, perhaps a rumble of thunder, for KCIU this afternoon, AOB 21-23Z. Worth keeping an eye on. Otherwise, south and southwest winds increase with gusts 25 to 30KTs during the afternoon and evening hours. LLWS will be possible this evening and early overnight if surface winds slacken. A few -SHRA remain possible into the overnight hours with decreasing winds, at least for the moment.
