Philadelphia: Seasonable air to return following midweek warmth, rain and wind

Unseasonable warmth will continue in the Philadelphia area until a storm with drenching rain and gusty winds rolls through on Wednesday.

Temperatures will continue to average 10-20 degrees Fahrenheit above normal through Wednesday. Temperatures typically range from a low in the middle 20s to a high near 40.

Springlike warmth across the Northeast

A rare February thunderstorm could occur on Wednesday.

While temperatures will challenge the record high of 62 last reached in 2006 on Wednesday, windswept rain is in store with the potential for travel delays. The rain could be heavy enough to cause urban flooding, especially where piles of snow are blocking storm drains.

Since a significant amount of the existing snow from the storm in January, major river flooding is not likely from the midweek rainstorm. There can be significant rise on the smaller streams in the region, however.

With a return of sunshine late in the week, high temperatures will be within a few degrees of 40.

The latest indications are that a storm from the south will pass too far offshore to bring rain and snow across the area on Friday.

Another potent storm will be watched for possible impact on the area's weather spanning Monday to Wednesday of next week. Odds favor rain instead of snow or snow changing to rain at this time, unless the storm takes a track farther east.
