    Philly: Heat to Stay Away but Rain to Threaten This Weekend

    With a southerly flow of air turned off this weekend, heat will stay away from Philadelphia, but part of the weekend is likely to be unsettled.

    Temperatures will average near to slightly below normal this weekend. Temperatures typically range from a low in the middle 60s to a high in the middle 80s F around the Philadelphia metro area.

    A storm system from the Central states will cause rain to bulge northward for a time and brush the region Saturday into Saturday night.

    How much rain falls on Saturday and how quickly the weather clears on Sunday will depend on the strength of that storm system.

    According to Northeastern Weather Expert Dave Dombek, "A stronger, rather than weaker storm would allow more rain to fall farther north on Saturday but would also allow more drying and hence clearing farther south on Sunday."

    Low clouds and drizzle could linger in part of the area on Sunday, especially south and east of the city.

    "The daylight hours are long and the sun is strong this time of the year, so odds are in favor of clearing progressing across the region on Sunday," Dombek said.
