LATEST UPDATE . Discussion/Marine

DISCUSSION. (Today through next Saturday) Issued at 302 AM EST Sun Jan 16 2022

- Some lake effect still poised for Tonight/Monday

The forecast generally remains unchanged with good continuity regarding the arrival of some snow showers for tonight and through much of Monday. We continue to think that we will not see significant accumulation by January standards.

We will see mainly clear skies this morning, before mid and high clouds arrive through the day. Snow showers are expected to hold off pretty much until 00z or after for the NW areas, and later further South and East, if at all. It is at that time that an upper short wave arrives, and colder air at the surface.

Most of the snow shower activity will be of the lake effect variety, as the upper trough runs into the storm system bringing the wintry weather to the srn and ern portions of the country. A bit of ridging aloft holds on over the area with the main low over the NE. Lake effect parameters are marginal with the 850 mb temps around -10C (delta t's around the 13C threshold). Forecast soundings indicate that inversion heights will keep the top of the convective layer around 5k ft, even with the lake modified parcels.

The flow will become mostly NNW, keeping the snow showers limited to the coast. We could see a couple of inches or so by the time things wind down later Monday for the favored NNW flow areas. We do not anticipate needing headlines for this event at this time.

- Better chances for lake effect Wed through Fri with colder air

We will see a break in the precipitation develop Monday night and last into Tuesday. Some light snow remains possible up along U.S.-10 in the warm air advection occurring ahead of the next incoming low that will track north of the area. Other than that though, not much precipitation until late Tuesday night/Wednesday morning.

The cold front is expected to push through the area roughly between 06z and 12z on Wed. Good cold air advection will take place, and lake effect should get going by Wednesday afternoon as the over lake instability becomes sufficient. We will see a boost in the activity Wednesday evening and night as a well defined short wave approaches. The flow aloft then becomes cyclonic, and forecast soundings show modified inversion heights over 10k ft.

The flow continues to look to be in a NNW orientation once again, favoring the lakeshore. Instability will be moderate to extreme with 850 mb temps dropping to around -20C. Conditions will become less favorable for good accumulations by Thursday morning as inversion heights drop a little behind the short wave, and the DGZ drops down to almost being below the cloud layer. This will produce a finer and small flake. We could see this event needing a headline eventually. The snow showers will then slowly taper off on Friday.

Quite a bit of uncertainty exists beyond Friday, with additional energy coming into the picture. Last night, it looked like the upper trough/cyclonic flow would move out and give the area a break. Now, there is another feature that will be in the region, and could bring some additional synoptic snow. One thing looks for sure though, and that is we will be colder for most of the next week.

AVIATION. (For the 06Z TAFS through 06Z Sunday night) Issued at 1219 AM EST Sun Jan 16 2022

Most of the forecast period will be quiet with no impacts. The terminals are starting off with clear skies this morning, and should stay clear into the morning before high clouds start moving overhead. The exception to this are a few clouds from Lake Erie that may bring some 2k ft clouds to KJXN. These would be short lived as they are drying up.

Mid clouds will then move in late this afternoon. KMKG will see some low clouds around 2500 ft and a few snow showers develop toward 03-06z tonight. The other sights may see some of this, but it would be after 06z Mon.

MARINE. Issued at 302 AM EST Sun Jan 16 2022

Winds will be ramping up later today up North, and then tonight and Monday for the remainder of the area. We will issue a Small Craft Advisory(SCA) for these higher winds and waves that will last through Monday night.

There will be a break for early Tuesday, but winds will be on the increase later Tuesday and go through Wednesday night again. SCAs are almost a sure bet, with Gales a distinct possibility as some arctic air comes in. Freezing spray could also become a problem with the winds/waves combining with the arctic air.

GRR WATCHES/WARNINGS/ADVISORIES. MI . None. LM . Small Craft Advisory from 10 AM this morning to 7 AM EST Tuesday for LMZ849.

Small Craft Advisory from 4 AM Monday to 7 AM EST Tuesday for LMZ844>848.
