We have 16° at 6:30 this morning. Yesterday’s high was 35° before a brisk west wind behind a cold front dropped the temps to a low of 16.5°. With dry air in place, there were no lake effect snows.
Temperatures north of Grand Rapids are in the single digits this morning and in negative territory in the U.P. With the Great Lakes protecting us from extreme wind chills, we are lucky to be spared from what northern Minnesota is experiencing today as the coldest air of the season moves in.
Hazardous Weather Outlook
Light lake effect snow showers may bring localized accumulations of an inch or two today and tonight west of Highway 131, which could also lead to hazardous travel conditions.
- Cold with Lake Effect Showers into Tonight The coldest air of the season thus far continues to funnel in with 850mb temps expected to drop to near -20C across lower Michigan. Temperatures around daybreak this morning are expected to be in the teens to single digits. West winds will still be just a touch breezy compared to a typical morning with winds at around 10-15 mph, so wind chills will be down into the -15F to 0F degree range early this morning. Afternoon temps will only warm into the teens with wind chills still hanging down in the -10F to 0F range. Lake effect snow showers will then be the other point of focus for the next 24 hours. Model soundings still show very shallow moisture (easily limited to below 5000ft) with the DGZ also near the surface. Therefore small flake sizes should limit accumulations to about 1-2 inches across the lakeshore counties. While snow accumulations should be limited compared to what we saw last week, visibilities may still become restricted in heavier snow showers leading to some hazardous travel. High pressure will slide in Tuesday morning cutting off northwest flow and put a stop to the lake enhanced showers. - Warming Mid-Week Strong high pressure will move to our southeast into the Ohio Valley Tuesday with a surge of warm air advection kicking off Tuesday afternoon. With a tight gradient setting up over lower Michigan, southerly winds will turn gusty Tuesday afternoon and evening with gusts up to 30-40mph possible. Temperatures will start out in the single digits Tuesday morning, but will quickly warm throughout the day and night into Wednesday. We will see a chance for some light precip Wednesday into Thursday as a weak clipper slides across our north, but limited moisture should keep much of the light snow at bay. - Possible End of the Week System In true fashion, deterministic model guidance has diverged considerably within the last 24 hours in regards to the possible weekend system. The Canadian holds true to measurable snow, while the GFS and Euro have backed off due to varying evolutions of the upper level trough. Meanwhile, long range Euro and GFS ensembles still suggest widely varying amounts of snow impacting the area. So overall we still expect some amount of snow next weekend, but with significant uncertainty still present in model guidance, the details on amounts, timing, etc. are still very muddled.
