Pittsburgh Weather Cloudy skies snow showers
Pittsburgh is facing the coldest days of the season with snow chances and alerts, followed by a brief warm-up. Stay informed!
The next two days are going to be the coldest of the season so far, with today and tomorrow being First Alert Weather Days due to late day snow chances. A trough of Canadian air will be dropping into place, causing temperatures to drop and snow showers to develop. The polar jet will push very cold air into the region, leading to dense squalls of snow moving through Monday evening and most of Tuesday. This will not be pleasant for anyone stuck outside for any period of time.
As of 5 a.m. on Monday, only Mercer and Venango Counties are under any type of advisory for overnight snow showers, but it is likely that advisories will be issued for the westward-facing slopes of the Laurel Highlands, along with the Ridges of Fayette and Westmoreland Counties. These communities are expected to see most of their snow overnight, with the lake effect snow event lasting around 24 hours and really picking up after sunrise on Tuesday.
The coldest air of the season will be in place by tonight, with temperatures remaining cold throughout Tuesday and not as cold on Wednesday. However, Wednesday and Thursday are looking dry with highs in the upper 30s and mid-40s, respectively. Another rain chance is expected on Friday with highs in the mid to upper 40s. Stay aware and be prepared for the cold and snow over the next couple of days.
