Tuesday breaks more records for warmth as cold front moves in
Metro Detroit had another day of record-breaking warmth Tuesday, but a change is blowing through at night, bringing more seasonable conditions the rest of the workweek.
Detroit Metro Airport reached a high of 77 in the afternoon, breaking the previous record, 68, set in 1999. The normal high for the date is 52.
Flint and Saginaw both beat records set in 1931, hitting 78 and 75, respectively. In the Upper Peninsula, Sault Ste. Marie reached 68, surpassing a record st in 2016 of 62 degrees, according to National Weather Service records.
A temperature change is coming, though, as a cold front pushes through the region. The weather service calls for a chance of thunderstorms by 1 a.m., with wind gusts as high as 40-45 mph in some spots.
In the Grand Rapids area, those winds could gust to 50 mph.
There is a risk of severe outcomes due to high wind; utility companies are urging caution during power outages and around downed power lines.
Temperatures are set to fall more than 20 degrees, topping out only in the low 50s on Wednesday and Thursday, with lows in the 30s.
The forecast calls for highs in the upper 40s on Friday.
That's a shift from the summer-like warmth that started last week and shattered longstanding records across southeast Michigan on Tuesday.
Detroit had a high of 77 on Monday, breaking a Nov. 9 record of 75 in 1999.
The city hit 73 on Sunday, which broke a record for Nov. 8 of 71 set in 1915, according to the National Weather Service.
The prolonged stretch of warm weather started Nov. 4 with a high of 72.
The unseasonable temperatures were driven by warm air over the Great Lakes, meteorologists say.
"The reason for that is a large dome of high pressure that's been parked over the eastern U.S., and it's been driving an influx of warm air up into the Great Lakes," said Steve Considine, a meteorologist with the National Weather Service. "So pretty much most of the central and eastern U.S. has been very warm this past week."
Considine said the highs for the past six days have averaged 15 degrees above normal, which for this time of the year is usually in the low 50s.
