Philadelphia is trading in its recent taste of spring for a chilly slap in the face on Thursday, March 12, 2026. Rain and blustery conditions moved in early, with temperatures near 60°F this morning set to tumble into the 30s by afternoon. Northwest gusts in the 25 to 35 mph range will make it feel more like the 20s and could create slick spots on bridges and elevated roadways.
Morning Commute: Rain Then Rapid Cooling
Steady rain is expected between about 7 a.m. and mid-afternoon Thursday, with the heaviest and most widespread precipitation during the morning into early afternoon. Forecasters say new rainfall amounts between a quarter and a half inch are possible, and the chance of precipitation is highest during the day as temperatures fall through the 50s into the 30s, according to the National Weather Service Mount Holly. Drivers should plan for slower travel times and patchy reduced visibility during heavier showers.
Afternoon Winds Pick Up
By Thursday afternoon, northwest winds will ramp up to 15 to 20 mph with gusts as high as 35 mph, knocking wind chills into the upper 20s to low 30s by late day. High-profile vehicles should use extra caution on bridges and exposed routes, and cyclists and pedestrians can expect a blustery, uncomfortable walk home. Some small branches may come down and exposed neighborhoods will be dealing with plenty of noisy gusts.
Wet Snow Mostly on Grassy Surfaces
As colder air pours in this afternoon, that rain is likely to mix with and briefly flip to wet snow, mainly late Thursday into early evening. Given the recent record warmth and warm pavement temperatures, any slushy accumulation should stay confined to lawns, grassy medians and other non-paved surfaces rather than roadways. The quickest changeover to snow is most likely near and south or east of the I-95 corridor.
Small Craft Advisory for Coastal Waters
Out on the water, it is not a great day to play captain. Small Craft Advisories are up for coastal and bay waters through the day, as seas and gusty winds whip up choppy, hazardous conditions. Anyone planning to be on or near the water should secure loose gear and consider staying in port until conditions ease later Thursday evening.
Looking Ahead
Friday is expected to bring a cooler but mostly sunny day. Saturday looks dry but gusty, with low humidity and 25 to 30 mph gusts Saturday afternoon that could raise some fire-weather concerns in outlying areas. A stronger system is on track for Sunday night into Monday, with widespread rain and a chance for thunderstorms before a colder push late Monday that could turn precipitation back to snow in some spots. Temperatures are forecast to run well below the recent highs into next week, with afternoon readings in the 30s and low 40s by midweek.
How to Prepare
Allow extra travel time, especially during the morning rain and afternoon cooldown. Secure outdoor furniture and umbrellas, and avoid taking high-profile vehicles across exposed spans during the strongest gusts. Keep an eye on updates from the National Weather Service and check transit status before heading out.
