Thunderstorms and a slight chance of severe weather could complicate this afternoon's rush hour, according to the National Weather Service.
"We may get some brief downpours that could cause ponding on roads and drainage problems, so drivers need to use caution," said Lee Hendricks, a meteorologist with the National Weather Service.
This morning's rush hour was slower than normal because of heavy rain. By 7 a.m., a quarter inch of rain had fallen at Pittsburgh International Airport.
The fast rain briefly closed a section of Route 65 near Sewickley and caused some flooding on roads near Morgantown, W.Va. Traffic on Route 28 slowed down near the 31st Street Bridge because of ponding near a construction area along the highway.
This afternoon, scattered thunderstorms are likely between 2 p.m. and 7 p.m. Rain will end by midday Thursday and could return Friday night and early Saturday.
On Sunday, the weather service says, there is a chance of snow showers.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.
While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.
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. Don't include URLs to Web sites.
We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.
We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.
We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
