Summer-like temperatures on the way for Thursday, with a good amount of sunshine
If you like warm weather, this forecast will be for you as temperatures for many will feel more like summer.
For Thursday, early patchy fog will burn off quickly throughout the morning under mostly sunny skies. Northern Michigan will be under the influence of high pressure today, but will gradually slide off to the east of the Great Lakes. As high pressure exits (and low pressure begins to move across the Dakotas), a southwest flow will develop and help boost daytime temperatures into the lower to middle 80s for nearly all, which is about 10-15 degrees above average for late-May. The lone exception will be the lake shore communities (lake breeze), with lower 70s for highs. All in all, mostly sunny skies will be the theme all across northern Michigan throughout the day. With that said, an isolated shower/thunderstorm is possible late in the evening across the E. Upper as there will be some instability nearby due to the slow moving disturbance off in the Dakota.
It will be a mild Thursday night with upper 50s to lower 60s for overnight temperatures - starting to approach readings where the air conditioner will be better than having the windows open! Scattered showers/thundershowers will be present in the Upper Peninsula, some of which may drift into the E. Upper. No severe weather is expected, but a few rumbles of thunder are definitely possible as there will be modest instability in the vicinity. For the N. Lower, a mostly dry forecast is expected, especially the farther south you lie.
While the above mentioned disturbance inches closer to the Great Lakes/northern Michigan on Friday, scattered shower and thunderstorm action will be mostly confined to the E. Upper & Straits. Again, any activity will be on the scattered side and a washout is not in the forecast. An increasing southwest flow will continue to pump in a very warm air-mass, with high temperatures cruising into the 80s for many (all the inland communities with even 90 degrees possible in the NE Lower. The lake shore communities will be a few degrees behind in the 70s.
Scattered shower and thunderstorm chances work into the forecast Friday night and Saturday for both the E. Upper and N. Lower as the disturbance slides through. A washout is not expected, but be prepared for an occasional shower or thunderstorm in this time frame - especially if you are partaking in any Memorial Day weekend plans. Temperatures will continue to stay mild all weekend long, with 70s and 80s throughout northern Michigan.
