Yesterday we had a high of 43.5° and a low of 37°.
We have settled into a cloudy/wet pattern that will continue the rest of the week, including snow chances, as colder air settles in, especially during the long Thanksgiving Weekend.
Most of the U.P. is under a winter weather advisory today and tonight.
While the snow has been delayed in getting here early this morning, we are still on track to receive generally 3 to 6 inches of mostly wet snowfall across most of Upper Michigan today and tonight. Expect the transition to pure lake-effect tonight, with the lake-effect machine continuing through the rest of this week into this weekend.
From the Gaylord NWS office:
A clipper system will bring our first decent shot at accumulating snowfall for the eastern UP. 3 to 6 inches…or even a little more in a few localized spots…could fall by Tuesday morning…with the worst conditions expected between 5 and 10 p.m. This system appears to be more straightforward than the previous one.
From the Grand Rapids NWS Office:
Real winter weather is set to arrive in Lower Michigan later this week, and it could slow down travel with slick roads, possibly starting Thanksgiving, then likely continuing through the long weekend with heavy lake-effect snow in some areas. Until then, mostly light rain or snow showers the next few days.
Weather History
950: The temperature plunges to an incredible 14 below zero at Muskegon, for the coldest November temperature on record. Grand Rapids hits 10 below for their November record low.
2004: A snowstorm drops between 3 and 10 inches of snow across southwest Lower Michigan. Grand Rapids has a daily record snowfall of 9.7 inches.
On November 25, 1950, it was a very cold and snowy day. A snowstorm hit on this date and continued into the early morning hours of November 26. Total accumulations were 6.2 inches in Saginaw, 8.1 inches in Flint, and 6.3 inches in Detroit. Also during the same time period in 1950 Detroit, Flint, and Saginaw all experienced record lows for 2 or 3 days. Temperatures in Detroit were 7 degrees on the 24th and 10 degrees on the 25th. In Flint, temperatures were 5 degrees on the 24th and 9 degrees on the 25th, and in Saginaw, temperatures were 7 degrees on the 23rd, 0 degrees on the 24th, and 7 degrees on the 25th.

Forecast Discussion
- Periods of showers into early Tuesday We had the first round of light showers pass through last evening associated with the nose of a low level jet and leading edge of better moisture transport. This band is in the process of moving out of our forecast area to the NE as of 2:30 am/0730z, with just some patchy light showers centered roughly near I-96. We are expecting multiple periods of showers to continue for today and tonight with multiple upper waves poised to move through the area. The first of which is over IA early this morning, will arrive by 12z. This will prolong the low level jet pumping moisture into the area this morning, and provide some weak instability for a few more showers to develop. Then the main wave will arrive toward dark this evening, providing more showers with better moisture to work with by then. This will then sweep most everything out by 12z Tuesday. Some light precipitation in the form of light rain or snow could continue into Tuesday along the U.S.-10 corridor as additional upper energy will be affecting mainly Northern Lower. - Light rain and snow Wednesday into Thanksgiving Day We should see a lull in the precipitation for most of the area Tuesday into early Wednesday before some light rain/snow chances arrive for Southern Lower. Some light precipitation in the form of light rain or snow could continue into Tuesday along the U.S.-10 corridor as additional upper energy will be affecting mainly Northern Lower. The rest of the area will be seeing ridging building in between the departing wave from today, and the next wave coming in later Wednesday. It will be noticeably cooler on Tuesday with temperatures likely falling through the day as the colder air arrives. The light precipitation coming in Wednesday will be associated with the next wave that will see phasing from a wave coming in from Canada and another that is currently the low offshore of the Pacific NW. This will support sfc low development that will travel now just south of the Ohio River Valley. The far southern rows of counties will be on the far northern periphery of the precipitation shield with this system centered on Wednesday night. Snow amounts and related impacts (especially with Wednesday being a high volume travel day) remain a little uncertain still at this time. The general consensus is that most of the snow with this system will be centered across Northern Indiana and Ohio. However there are still a few ensemble members that have the track a little further north, and dump a little bit more snow for our southern two rows of counties. Drier air on the northern edge of the precipitation shield should reduce the amounts a bit. The good news is that most of it will happen after dark, and hopefully after many are done traveling for the holiday. We will continue to fine tune the forecast with the latest trends. It does look like most of the holiday itself will be quiet and cool as short wave ridging builds in for the daylight hours. - Colder with lake effect snow showers Thu night and beyond The break on Thanksgiving Day itself will be short lived, as another stronger short wave arrives Thursday night and into Friday. This scenario will have the upper jet core dropping south of the area, and allowing the deep colder air and cyclonic flow to become entrenched over the area. 850 mb temps are expected to drop to between -11 and -13C, providing for more than sufficient instability over the lake with delta t`s in the 20`s C. The dominant flow pattern looks like it will be from the WNW. This will favor all of the lakeshore, and most of the SW quadrant of the forecast area. These areas are likely to see advisory type snows Thursday night into Friday night. We should see a break in the lake effect intensity centered around Saturday, as the models are showing that we see some short wave ridging build in. The upper jet core retreats temporarily north of the area. This will be short lived as yet another short wave drops down Saturday night, that will bring the jet back south of the area. We should see the lake effect ramp up at that time, and continue at least through next Sunday. The flow looks again to be from the WNW, but that is likely to change a little being seven days out yet.
WWA coming stay tuned ….INDY
