Philadelphia weather: Rain gets heavier throughout the day, Flood Watch in effect thru Sunday
PHILADELPHIA (CBS) -- After a bright and sunny Friday, you'll want to keep the umbrellas and rain gear close today. Several disturbances will roll past the region with heavy rain developing later this evening.
Scattered sprinkles move in Saturday morning before the rain picks up later in the afternoon, between 1-2 p.m. Meteorologist Tammie Souza said we can expect steady rain by 4 p.m. and could see some heavy bands of rain in Philadelphia by 7 p.m.
Overnight we could have periods of heavy rain with isolated thunderstorms into very early Sunday morning. Rainfall of 1-3 inches is possible especially under any thunderstorm.
With all this moisture expected to fall throughout the day, a Flood Watch goes into effect at 1 p.m. until 8 p.m. Sunday for all areas adjacent to the I-95 corridor including Philadelphia, Delaware county, lower Bucks and lower Montgomery counties in Pennsylvania and all of South Jersey away from the shore.
River, stream and creek flooding is likely with ponding and localized flooding on the roadways. Tonight travel on roadways will be slow at times and flight delays are likely at Philadelphia International Airport.
There is also a Coastal Flood Warning in effect through 7 p.m. Sunday for all low-lying areas and tidal ways near the Delaware River including the Philadelphia shoreline. Moderate flooding with 1-2 feet of inundation is possible at the high tides on Saturday and Sunday.
A separate Coastal Flood Advisory is in effect through noon Sunday for the shore points and back bays of South Jersey and Delaware. Up to 1 foot of inundation is possible at the high tides with street flooding the main concern. Despite the rain temperatures will climb to the low 50s later today.
Daylight Saving Time / St. Patrick's Day Parade
It's almost time to spring forward! Don't forget to turn those clocks ahead one hour tonight as Daylight Saving Time begins at 2 a.m. Sunday. Enjoy the extra hour of daylight in the evening, your sunset will be 7:02 p.m.
Sunday, we will have 11 hours and 43 minutes of daylight!
The luck of the Irish is with us tomorrow as the rain is expected to clear the area early in the morning leaving partly cloudy skies and dry conditions for the Philadelphia St. Patrick's Day Parade, but the winds following the storm will be howling so hang on to your green hats!
Those wind gusts to 35 mph will combine with highs in the upper 40s to create a feel-like temperature in the 30s and 40s. There are currently no wind advisories issued for our area, but they may be possible on Sunday if the expected wind gusts trend above 40 mph.
And if you're craving warm, spring weather, you're in luck! The end of this week has temperatures reaching the high 60s and even low 70s by Thursday and Friday. If we reach 70 in Philadelphia that will be the first time this year and the first time since Nov. 9, 2023. Rain chances return by late Friday.
