Another wintry Wednesday is in store for the Buffalo Niagara region.
Winter weather advisories are posted across Western New York as the result of a storm system that's expected to bring snow, sleet, freezing rain and rain to the region.
It'll be the fifth consecutive Wednesday with inclement wintry weather that's often involved freezing rain – along with a late January blizzard and last Wednesday's unexpected afternoon rush-hour snow squall.
The winter weather advisory is posted from 1 p.m. to 10 p.m. Wednesday for northern Erie County along with Niagara, Orleans and Genesee counties.
The weather service is calling for mixed precipitation with ice accumulations up to a few hundredths of an inch and less than an inch of snow. Forecasters expect periods of snow, sleet or freezing rain to result in slippery roads and limited visibility at times.
The evening commute could be hazardous, again.
"Ice accumulation will be problematic given temperatures warming so rapidly, not to mention a changeover time in the afternoon from snow to freezing precipitation," the weather service said.
It added: "We are now in late February, and the sun is strong enough to keep pavement temperatures above freezing in the afternoon even with temperatures a bit below freezing, so the impacts may not be very substantial even if freezing rain does occur."
In southern Erie County south of Route 20A as well as Wyoming County and the western Southern Tier, forecasters said an inch or less of mixed precipitation is forecast with ice accumulation of a few hundredths of an inch and winds as high as 40 mph.
Precipitation is expected to start as snow late Wednesday afternoon, transitioning to mixed precipitation as temperatures warm slightly above freezing and then to light rain overnight into early Thursday.
The weather service said gusty winds are expected behind the storm system. Breezy west winds are forecast Thursday with gusts over 40 mph in metro Buffalo, forecasts show.
Forecasters said there are slight chances for light rain Thursday morning.
Here's a look back at some of the highlights from Buffalo's past four wintry Wednesdays:

- Wednesday, Jan. 30: Commute will be nasty as 1-2 inches of snow per hour falls on metro Buffalo, Southtowns
- Wednesday, Feb. 6: Nearly 7,000 without power in Erie County as freezing rain coats WNY with ice
- Wednesday, Feb. 13: Nasty Wednesday evening commute snarled by whiteout conditions, snow squalls
