The warmer weather from the past few days, when highs reached the 50s on Wednesday, will soon be a thing of the past.

Time to grab those heavy coats, hats, gloves, scarves and —yes — snow shovels once again as more snow is on the way.

Thursday's highs in the Topeka area should crack the 50-degree mark for the second consecutive day. Not bad.

But a cold front that will push through the area later in the day on Thursday will bring with it a chance for snow and drop temperatures, with highs in the 20s on Friday and Saturday and around 30 on Sunday.

The National Weather Service has issued a Winter Weather Advisory is in effect for north-central, east-central and northeast Kansas from 6 a.m. Thursday through 6 p.m. Friday.

An upper-level disturbance will move east across the state on Friday, bringing a chance for snow, according to the weather service. The heavier snowfall will be along and north of a line extending from Concordia to Topeka to Lawrence.

Total snow accumulations of 2 to 4 inches are expected to fall between 6 a.m. and 6 p.m. Friday.

Plan on slippery road conditions and potentially hazardous conditions on the morning and evening commutes on Friday.

City crews were treating streets and bridges in advance of the anticipated storm.
