About four inches of ice covers most of the Allegheny River beneath the Tarentum Bridge on Monday, Jan. 1, 2018.

A number of school districts in the region have announced two-hour delays and some closures for Tuesday because of the frigid weather.

A wind chill advisory where temperatures can plummet as low as -15 is in effect in Southwestern Pennsylvania until noon Wednesday, according to the National Weather Service in Moon Township.

A second advisory was issued for the higher elevations in the Westmoreland and Fayette counties' ridge areas where wind chills could dip down as low as -20 degrees.

Temperatures Tuesday morning hovered between 3 and 9 degrees throughout the region, according to Chris Leonardi, meteorologist with the National Weather Service.

The only break in the frigid weather comes Wednesday, when temperatures are expected to reach a high of 23 degrees; however, the region is expected to plunge back down into single-digit temperatures with a low of 8 degrees Wednesday night into Thursday morning; Thursday will offer a high of 14 degrees, with lows back to -1 at night and into Friday, with wind chills of -15, according to the National Weather Service.

Forecasted daytime highs for the weekend will be: Eight degrees Friday, 11 Saturday and 24 Sunday.

Monday's forecast high of 38 will be followed up by another cold snap.

We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers

We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING.
