AccuWeather: First 80° day of the year today for the Philadelphia region

PHILADELPHIA (WPVI) -- Today has a June-like feel, but a backdoor cold front arriving tomorrow will cause temperatures to vary widely.

TODAY: It will be our warmest day since Halloween! It'll be a great day to be outdoors with a mix of clouds and sun and a gusty breeze up to 35 mph. High 82, 70s at the shore.

TONIGHT: Clouds take over, patchy fog possible. Low 52.

SUNDAY: The front that's to our north on Saturday will slip back southward as a back door cold front. Where this ends up will likely bring a sharp contrast in temperatures across the area. Some locations could be well into the upper 70s south of the boundary, where other locations north of the boundary may end up in the 60s. It's a cloudy day with highs near 70.

MONDAY: It's a cloudy start to the week, and we could have scattered showers at any point during the day. With enough instability, we could even have a couple of thunderstorms. This could put the Phillies' Home Opener in jeopardy, high 74.

TUESDAY: Turning brighter, but it's much cooler for the first day of April, high 57.

WEDNESDAY: Another cool day with high clouds streaming in, high 54.

THURSDAY: Mild again with scattered showers and thunderstorms possible, high 72.

FRIDAY: Morning showers, high 69.

SATURDAY: An additional rain chance, clouds. High 62.
