Pittsburgh: Brief Return of Winterlike Chill This Week

After the week started with soaring highs in 70s and 80s, temperatures will plummet below normal for the middle of the week.

Spring is the season known for drastic temperature swings, and this week will certainly be an example.

Approximately 30 degrees will separate the high in the 70s on Monday and Tuesday's high near 45 degrees.

This wave of cold air is following behind a storm system that will bring showers and thunderstorms late Monday into Monday night. Thunder is expected to subside by Tuesday, but as rain tapers off, temperatures will drop throughout the day.

Temperatures will get low enough by Tuesday afternoon that a trace of snow could mix in with rain showers.

A chilling low in the 20s is expected on Tuesday night, cold enough for the rain on some surfaces to freeze for the morning commute Wednesday.

However, temperatures are expected to rebound rather quickly with the return of sunshine. Highs will climb to near 50 on Wednesday and rise near average in the lower 40s on Thursday as sunshine persists.
