Continuing The Tropical Muggies

We have one more really humid day in store for the region today -- we're starting off in the mid and upper 70's with dew points that are not much lower than those temperatures as the tropical airmass from Isaac's circulation is overhead.  A cool front is to our west and it is slowly pushing east this morning, with a line of showers and storms associated with it.

Scattered showers and storms will be with us today as the front moves through, with any of the storms producing heavy rains that could lead to localized flooding and ponding of water on roads.  A flash flood watch remains out for the region until 8 PM for the potential of heavy rains causing some additional flooding problems.   Rainfall in Philadelphia yesterday ranged from three inches at the Airport in Southwest Philly to over five inches in Northeast Philadelphia, with a two-day total of six inches in Northeast Philadelphia.  It won't take much rain to get local streams and streets to become a water hazard.

These showers and storms will be more prevalent from late morning through early this evening as the front approaches and crosses...until then, it will be humid with a few peeks of sunshine through clouds.  Highs will reach the middle 80's this afternoon before any thunderstorm activity begins to cool us (slightly).
