It is 20 degrees colder, than yesterday at this time, west of the
mountains. East of the mountains, temperatures are a few degrees
warmer. Clouds continue to cover the entire state with a few showers
falling as a result of an upper level low pressure system, tracking
along the Mason Dixon line.

High pressure will build in after the upper level low passage and
bring mainly dry conditions later today, right into early Friday.
Sun may be in short supply this afternoon. Only areas east of the
mountains will see any breaks in the clouds. Afternoon high
temperatures today will range from the upper 30s across the northern
mountains to near 50 degrees across the southeastern piedmont.

Clouds will linger through tonight into Thursday morning over the
mountains. Morning clouds Thursday will give way to a brief period
of clearing for the afternoon and evening hours.

Low pressure over the midwest will push another warm front back
north across the commonwealth during the day Friday. This front will
be accompanied by periods of rain during the day Friday. 

Temperatures late this week and right into the middle of next week
will be persistently mild, averaging greater than 10 degrees above
normal.
