KEY MESSAGES
- Quick Hitting Light Snow Tonight
- Potential for Lake Effect Snow Tuesday Night
- Chance of Snow/Mix Late Thursday/Friday
- Better Chance for Precipitation Next Weekend/Early Next Week
UPDATE
Issued at 956 PM EDT Mon Mar 18 2024
The few remaining lake effect flurries continue to fade as next shortwave diving south of Lk Superior approaches. Latest short range guidance still not very bullish with snow from this feature later tonight/early Tuesday, showing only a few tenths mainly north of I-96 and near/west of 131.
DISCUSSION
Issued at 311 PM EDT Mon Mar 18 2024
- Quick Hitting Light Snow Tonight
As the upper level trough continues to shift east, we'll remain in northwest flow for the next few days. Within this flow there will be a series of shortwaves that will bring chances for light snow.
As warmer temperatures advect into the area lake effect snow tapers off by the early evening. The 850 mb to 700 mb warm air advection will bring another round of lift and paired with a quick moving round of 500 mb positive vorticity advection should be enough to produce light snow mainly for areas along and north of I-96. Snow amounts under a half inch are expected and with lows in the 20s could cause some slick spots for the Tuesday morning commute. We lose our moisture during the day Tuesday resulting in dry conditions with highs in the low to mid 40s.
- Potential for Lake Effect Snow Tuesday Night
Northwest winds and colder air move into the area Tuesday evening bringing with chances for lake effect snow. 850 mb temperatures are expected to be around -12C and with lake surface temperatures 5C it should be an overall good set up for at least some light lake effect with the west northwest flow.
- Chance of Snow/Mix Late Thursday/Friday
Dry conditions return Wednesday as high pressure moves over the region. Breaks in cloud cover will be possible Wednesday with more sunshine expected for Thursday. Chances for precipitation increase overnight Thursday into Friday as an upper low moves east into the Great Lakes Region. An area of snow will track from the northwest along a cold front bringing a light accumulation of snow. Ensembles are narrowing in on the possibility for a few inches of snow possible across the area.
- Better Chance for Precipitation Next Weekend/Early Next Week
A more impressive system appears to be on the horizon with the potential to produce a rain/snow mix late in the weekend. A southern stream system with deeper gulf moisture advection ahead of the low will place lower Michigan in the warm sector. A mix of precipitation is possible, including snow and/or freezing rain then rain.
Thunderstorms will also be possible.

IR loop shows the back edge of the stratocu moving east across the lake. Concurrently, mid/high clouds were noted streaming southward from Ontario. Snow showers were also diminishing. We are likely to see the lower clouds decrease overnight leaving VFR conditions at the terminals that are currently MVFR.
The next wave of low pressure will move southeast through the state Tuesday. Gusty southwest winds to nearly 30kts are expected from late tonight through mid afternoon. Winds will shift to the northwest late Tuesday afternoon/evening.
MARINE
Issued at 311 PM EDT Mon Mar 18 2024
Winds briefly subside and turn to the southwest this evening before building once more. Gusts up to 30 knots are expected but could approach gales Tuesday morning. A front moves through during the day Tuesday with northwest winds Tuesday night into Wednesday.
Winds and waves again are expected to hit Small Craft Advisory levels with the potential for isolated gales during the day.
Winds and waves finally subside for Thursday and remain below Small Craft Advisory levels through the weekend.
