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.

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.

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!

Rain chances return by late Friday.
