As a warm front slowly approaches from the southwest today, showers will develop throughout the Philadelphia and New York City metropolitan areas. Initially, a few of these showers are actually snow and sleet showers, especially over portions of northeastern Pennsylvania, northern New Jersey, all of southeastern New York including New York City, and all of Connecticut.
As warm air continues to overwhelm the cold air in place, all locations will have temperatures rise above freezing as the morning progresses with all rain expected by the middle of this morning. No accumulation is expected, but a few slick spots will be an issue for the morning commute.
Overcast skies can be expected today with scattered showers increasing in coverage. Winds will veer to the south at 5 to 10 mph with temperatures rising slowly into the upper 30's to mid 40's through this evening.
Rain will become wide spread as an area of low pressure over the Mississippi Valley lifts northeast towards the eastern Great Lakes. Winds will continue to veer to the southwest at 10 to 15 mph with higher gusts. Temperatures will continue to slowly yet steadily rise through the 40's and into the 50's by tomorrow morning.
Rain, heavy at times, can be expected through tomorrow afternoon followed by clearing skies. Winds will veer to the northwest behind the passing cold front at 10 to 20 mph with higher gusts. Windy conditions can be expected through tomorrow evening. Temperatures will peak in the lower to mid 50's ahead of the cold front.
High pressure will take hold by Saturday morning with windy conditions lingering into the afternoon. Otherwise, dry conditions are expected for Saturday on through Tuesday. Temperatures will range from the mid 20's to mid 30's for lows and lower 40's to lower 50's for highs for Saturday and Sunday. The coldest day of the period will be on Monday with lows in the lower 20's to lower 30's and highs in the mid to upper 30's.
A warm front will approach on Wednesday with scattered showers. Temperatures will rebound into the lower to mid 30's for lows and mid 40's to lower 50's for highs.
