- 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.
AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/
Issued at 147 AM EDT Tue Mar 19 2024
VFR conditions will continue through Wednesday evening. Stratus deck will prevail with bases around 3500 to 5000 feet AGL this morning. West winds will gust over 20 kts this morning then go northwest in the afternoon.
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.
