Weather History

1958: Record high temperatures are set all across Lower Michigan as a southerly flow of air pushes afternoon high temperatures to around 70 degrees. At Muskegon, the temperature hits a record 71 degrees for the second day in a row.

2014: Arctic air prevails, with high temperatures in the teens and heavy lake-effect snow. Nearly 10 inches of snow fall at Grand Rapids, contributing to a record November total of 31 inches.

On November 18, 2016, unusual late-season Autumn warmth shattered record highs for the date across the region. Detroit reached 73 degrees (breaking the previous record of 69 from 1941) while Flint and Saginaw both reached 71. Their previous records were 69 (1941) and 68 (1975) respectively.

Also, on November 18, 1959, Flint experienced two days of record lows: 9 degrees on the 17th and 11 degrees on the 18th.

Forecast Discussion

- Rain Developing Late Today

A strong southern stream wave will push a surface low north from
Oklahoma today to Minnesota Tuesday. A band of rain will develop
southeast of the low near the warm front as isentropic lift
strengthens and condensation pressure deficits fall to less than
10 mb. Models have been consistent in showing this wave for
several days as it moves north and phases with a northern stream
upper low. For today, rain will move into the cwa from the
southwest late this afternoon and move across the entire cwa
through early evening. After a brief lull around midnight, more
rain will develop late tonight as the occluded front moves toward
the cwa and continue Tuesday before diminishing late in the day.

- Continued Unsettled and Turning Cooler Mid to Late Week


The same fcst challenges still exist with the mid to late week
system. While guidance has been consistent in carving out a deep
upper trough over the GrtLks Rgn by Thursday, they still differ on
the evolution/placement of the main upper low center and resultant
sfc cyclogenesis and thermal profiles. Thus still low confidence in
potential fcst outcomes.

The more northern placement of the GFS near Sault Ste Marie (then
south from there) ends up sending colder H8 air in from the west.
This results in lake enhanced rain and snow showers with some
light/slushy accumulations possible inland from the milder Lk MI
shoreline on Wednesday night into Thursday (favoring higher
elevations up north as well as grass/fields vs roads).

The more eastern placement of the ECMWF in the vicinity of Lk Erie
meanwhile presents the (low probability) scenario for some synoptic
wet/slushy snow accumulations over south central and southeast Lwr
MI on Wednesday night, before warmer air wraps in around the the nrn
side of the system from the east and changes things back to all rain
for Thursday. The colder Irish Hills would probably be most favored
for some accums in this (unlikely) scenario, but a few ensemble
members still suggest several inches possible.

Otherwise showery/cool weather persisting through at least Saturday
with highs in the 40s until the upper trough finally lifts out later
in the weekend.
