Updated key messages for the very active week of weather ahead. A strengthening storm system passing to our northwest will bring high winds to the region, which will itself bring a multitude of hazards. Heavy lake effect snow will also develop downwind of the lakes and continue through much of the week. Wind gusts in excess of 50mph are already being observed across far western NY early this morning.
Strong to damaging winds of 65 to 75 mph today within the High Wind Warning areas (see graphics for your area). Strongest winds will be northeast of both Lake Ontario & Erie. All other areas, winds will potentially gust up to 55 mph. Prepare now in the event that there will be power outages.
Additional details regarding the timing of peak wind gusts through Thursday. Winds diminish some tonight, though remain very blustery through Tuesday.
Once lake effect snow develops downwind of the lakes, it will continue through much of the week. Snows will be intense at times in the heart of the lake effect areas with significant blowing and drifting, especially through Tuesday. Lake bands will not remain stationary, likely making northward and southward oscillations throughout the week.
Lake effect snow will initially develop northeast of the lakes today, first off Lake Erie starting late morning, with Lake Ontario to follow by the evening. While some uncertainty in initial intensity remains, lake effect snow off Erie combined with the strong winds may lead to a period of whiteout conditions with very treacherous travel this afternoon.
