Today's temperature won't get out of the 30s and there will be some clouds, but the weather also will feature something that's been absent all month: sunshine.

According to the National Weather Service, Valentine's Day will be the first this month to escape the cloud cover that has muffled the region under a gray blanket.

School kids and commuters likely will be the ones who appreciate the sun the most. Many students yesterday had to wait in the cold for buses delayed by the early morning snow and roads still tricky from Tuesday's snow.

Snow and ice may have played a role in a three-truck accident on Interstate 80 in Clarion County that killed a driver from New York.

State police said the unidentified driver was traveling westbound in Clarion Township when his tractor-trailer crossed the median and hit two other trucks. One other driver suffered severe injuries.

Commuters were caught predawn as rain changed to snow after temperatures fell across the region.

State police responded to nearly 50 mostly minor accidents from Tuesday at midnight until about 6:30 p.m. yesterday. That's about 10 times the number on a fair-weather day, said Trooper Robin Mungo.

She said "weather was a factor" but the main culprit was likely distracted drivers, like any other day.

The weather service characterizes a sunny day as one during which no more than three-tenths of the sky is covered all day by clouds. This month, five days have been partly cloudy and the rest cloudy.

Pittsburgh Public Schools received complaints from parents who were upset that the district did not call a weather delay yesterday.

Spokeswoman Ebony Pugh said attendance was affected in some schools but she did not have figures.

Ms. Pugh said some buses did not pick up students because of hazardous roads. In at least one case, she said, buses unable to reach schools returned students to bus stops.

Ms. Pugh said the decision to operate on a regular schedule was made before 5 a.m., when primary roads were clear.

U.S. District Court in Pittsburgh will reopen today following repairs to an electrical system.
