LATEST UPDATE . Aviation

SYNOPSIS. Issued at 330 PM EST Fri Dec 6 2019

-Above normal temperatures Saturday through Monday

-Dry Saturday and Sunday, rain showers Sunday night and Monday

-Rain showers changing to snow showers Monday night

-Arctic blast Tuesday and Wednesday with lake effect snow and travel impacts

DISCUSSION. (This evening through next Friday) Issued at 330 PM EST Fri Dec 6 2019

The primary talking point in the next 7 days is the Arctic blast and associated travel impacts next Tuesday and Wednesday. After a very mild period Sunday and Monday with highs well into the 40s and rain showers, the rapid temperature drop into the 20s and lake effect snow showers will likely result in a slick Tuesday morning commute. Travel impacts will persist into Tuesday night and Wednesday as H8 temps around -22C continue to pour in and generate lake effect snow showers.

Although inversion heights are progged to be relatively low for this event, around 5-6K feet, the DGZ is shown to be in the cloud layer - at least on Tuesday. This supports high snow ratios and production of dendrites. However on Wednesday as the coldest temps arrive, the DGZ lowers closer to the ground and supports finer snow crystals. Typically accumulations are on the light side when this type of snow occurs, but travel is greatly impacted due to reduced visibilities and icy roads.

In the meantime, we have relatively quiet weather this weekend. A ridge of high pressure builds in tonight and brings some clearing before another batch of clouds impacts areas near/north of I-96 on Saturday. We end up on the back side of the sfc high over the weekend and the southwest/return flow leads to a warming trend.

Guidance is in agreement that the main risk of rain holds off until Sunday night as the sfc front drops in from the northwest and stalls. The best chance of rain is on Monday as a sfc wave moves along the front. The cold air rushes in late Monday night once that wave moves by and winds shift northerly.

AVIATION. (For the 06Z TAFS through 06Z Saturday night) Issued at 1235 AM EST Sat Dec 7 2019

VFR conditions will prevail for much of the area this morning, however MKG may see some lower MVFR ceilings for the late morning hours before ceilings lift again. Otherwise southerly flow develops later today into tonight.

MARINE. Issued at 1133 PM EST Fri Dec 6 2019

The pressure gradient has weakened enough to limit the winds over the nearshore waters. Thus the waves have decreased as well. As a result we allowed the small craft advisory to expire. Conditions do change Saturday evening with increasing south to southwest winds. Headlines will likely be needed and the event could rise to the gale level. Mariners should plan on impacts returning this weekend.

HYDROLOGY. Issued at 330 PM EST Fri Dec 6 2019

Area rivers will continue to slowly recede over the weekend. Rainfall amounts Sunday night into Monday do not look excessive at this time (a half inch or less) and should have little impact on river levels. The cold Arctic air next week will probably result in some ice formation in the rivers.

GRR WATCHES/WARNINGS/ADVISORIES. MI . Lakeshore Flood Advisory from 7 PM this evening to 7 PM EST Sunday for MIZ037-043-050-056.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
