DISCUSSION

- Dry and Breezy with Elevated Fire Weather Concerns
A large upper level low off the east coast will swing an upper level wave through the region today. While this wave will be moisture starved, it will allow for a tightening of the pressure gradients over Michigan. That will allow for gusty winds this afternoon. Those winds, coupled with the dry air and temps in the 80s will bring elevated fire weather conditions. Winds will subside this evening. Warm and dry conditions will continue through at least midweek, however the low will shift eastward tomorrow and winds are expected to be lighter.
- Showers and storms possible late this week
A positively tilted upper level ridge and a large sfc high pressure system will dominate the weather this week. This will keep any advancing showers from the west to stall or move around it. This will keep the Lower Peninsula dry through Thursday. The models begin to diverge due to timing and position of the incoming low. However, the ridge will flatten and moisture flow will increase Friday into Saturday. Couple that will the fact that the sfc high will have shifted to the south east US. That will stream gulf moisture through the central US, the Great Lakes and then through the Mid Atlantic. QPF is not expected to be abnormal, NAEFS mean PWATS are near normal, however it gives us the next chance for showers and storms.
AVIATION /12Z TAFS THROUGH 12Z TUESDAY/
Issued at 655 AM EDT Mon Jun 1 2026
VFR conditions will continue through the period. Light and variable winds will continue and then during the daytime will become E/NE 5-10 kt Monday. Winds will become gusty after 18Z with gusts upwards of 20kts. Any gusty winds will subside this evening.
MARINE
Issued at 249 AM EDT Mon Jun 1 2026
Latest wind models have backed off a bit though the HRRR continues to have slightly higher northerly flow near the points. There is the potential for waves to build to near SCA criteria this afternoon. However, the winds shift to the east with the front and become offshore flow.
