WHAT HAS CHANGED

Winter Weather Advisory has been expanded to include Trumbull and Mahoning, OH due to impacts from snow showers and squalls this evening with the Arctic front. Snow showers are possible on Sunday with a shortwave moving through the region.

KEY MESSAGES

1) An Arctic cold front will pass through the region this evening bringing the potential for snow squalls, gusty winds, and blowing snow leading to hazardous travel conditions this evening.

2) Dangerously cold temperatures and wind chills are expected tonight as Cold Weather Advisories and Extreme Cold Warnings are in effect. Additional Cold Weather Advisories may be needed Saturday night into Sunday morning.

3) Snow showers possible on Sunday with generally dry weather expected after through Tuesday night. Another low pressure system will bring precipitation to the region mid-week.

4) Temperatures begin to moderate early next week with above- freezing temperatures expected through mid-week.

KEY MESSAGE 4

Temperatures will begin to moderate across the region early next week as a upper level ridge develops to the west and builds eastward through Wednesday. Generally, southwesterly flow will allow for warm air advection across the region and we'll see high temperatures climb above freezing on Monday. Highs on Tuesday will touch upper 30s and may even see 40s here and there before dropping down into the mid 30s again with the approaching low pressure system.

AVIATION /00Z Saturday THROUGH Wednesday/

Mixed-bag of VFR, MVFR, and IFR across the TAF sites this evening, with non-VFR conditions associated with both lower ceilings and vsbys. Main concern will over the next several hours, generally along and east of the I-71 corridor, as snow squalls may briefly reduce vsbys to 1/2sm or less along an arctic front, which is currently moving southeast across Lake Erie and Northwest Ohio as of 7 PM EST. These squalls may also produce brief wind gusts of 35 to 40 knots.

Behind the arctic front, non-VFR vsbys will remain possible in scattered snow showers and/or blowing snow as north to northwest wind gusts remain elevated at 25 to 30 knots. Mainly VFR should return late tonight into early Saturday morning as drier air enters the region, though will need to keep an eye across far Northeast Ohio and Northwest Pennsylvania where downstream Lake Huron moisture may lead to lake effect snow and/or clouds.

Outlook...Non-VFR possible in snow showers on Sunday, generally along and west of the I-71 corridor. Non-VFR possible in rain/snow showers Tuesday night into Wednesday.

MARINE

Lake Erie is ice-covered. A strong Arctic cold front this evening will bring Northwest gales 35 knots to the central and western basin tonight into early Saturday morning. Gusts up to 40 knots are very possible overnight. Some shift of the ice on Lake Erie may be possible due to the stronger winds. Northwest winds will continue on Saturday 10 to 20 knots and then become light and variable Saturday night into Sunday.
