PHILADELPHIA (CBS) — A high pressure system off the mid-Atlantic coast will bring in a southwest flow of warm, humid air, Tuesday.
High temperatures will climb well above average, into the upper 80s and the rise in humidity will be quite noticeable.
As a cold front approaches, the warm, humid air mass will help fuel some showers and storms, (with downpours) during the afternoon and evening.
In the wake of the front, Wednesday will be dry and sunny. High temperatures will be around 85 degrees.
Clouds will increase during the afternoon as our next system approaches.
That next system, a convective complex, (an organized group of storms) will move in from the Midwest, and is expected to stay together long enough to bring rain, some heavy, into the Delaware Valley Thursday morning.
There is also potential for gusty winds and lightning.
This will slow down the commute for some of us. This first wave of rain should clear the coast by late morning.
There is a chance of an afternoon shower or thunderstorm, as well.
Fortunately, this all clears by Friday as fair weather High Pressure builds back into our area.
Friday will be sunny with a high of 80 degrees.
The weekend looks pleasant as well, with lots of sun and highs above average, in the low to mid 80s.
