WHAT HAS CHANGED

No major forecast changes needed with this update.

KEY MESSAGES

1) Pleasant fall conditions expected to continue through the weekend. Patchy fog possible tonight into early Tuesday morning.

DISCUSSION

KEY MESSAGE 1... A Canadian high pressure will linger over the area through Tuesday before a weak cold front begins to push east across the area late Wednesday into Thursday. This frontal boundary is not expected to result in any precipitation. Ahead of it on Wednesday, temperatures will climb into the low to mid 70s before falling back into the upper 60s to low 70s on Friday. Low temperatures will be quite cool, especially tonight into Tuesday morning as amplified radiational cooling results in some areas dropping into the upper 30s especially in the typical cooler spots. Continue to opt for holding off on a Frost Advisory given the expected scattered nature. Will continue to monitor conditions over the next couple hours.

AVIATION /18Z Monday THROUGH Saturday/

VFR continues. Winds northwesterly gust 15-25kts through 22Z, then below 10kts overnight. Tuesday winds southwest less than 10kts, FEW flat cumulus FL040.

Outlook...Overall VFR conditions expected most of this week.

MARINE

Gusty northwest winds across the central and eastern basin of 15-20 knots will continue into tonight, resulting in waves of 3-5 feet pushing into the nearshore. These winds are expected to persist a bit longer than previously forecast, so the Small Craft Advisory has been extended until 4Z Tuesday. As the high pressure becomes more dominant over the area, winds will weaken across Lake Erie to 5-10 knots through Tuesday. Late Tuesday, a low pressure is expected to move east across Canada, ultimately moving a cold front east late Wednesday into Thursday. Ahead of this boundary, increased gradient will result in southwest winds of 20-25 knots Tuesday night through Wednesday. This will likely need an additional Small Craft Advisory. As the cold front pushes east, winds will back to be northwesterly and weaken to 10-15 knots. High pressure returns by the end of the week and allow variable winds of 5-10 knots.

CLE WATCHES/WARNINGS/ADVISORIES

OH...None. PA...None. MARINE...Small Craft Advisory until midnight EDT tonight for LEZ146>149.
