Steamy, heavy rains,some severe

Temps near 90 with a very moist atmosphere will mean conditions will
be favorable for heavy rain showers and storms today and tomorrow. The
heat will be on its way out starting tomorrow with many areas seeing
highs in the low to mid 80s verses the upper 80s and low 90s. Temps
will then stay in the low and mid 80s until at least Wednesday in the
north, some upper 80s in the south. The biggest difference will be the
lack of humidity which will be a welcome change.

In the meantime, synoptic features may develop the next 24 hours to
bring heavy rains to the Northern VA, central MD, Eastern PA, Western
NJ, on up through Eastern New England. Rains may be as high as 3 to 6
inches in what is known as a PRE. This is a feature that happens far
away from a Hurricane, but definitely is tied to the Hurricane's
influence on the storm pattern. If this does occur it appears to favor
areas northeast of the Northern VA and MD area, but may begin there.

Bill will impact the coast starting later today with high waves. He is
expected to start moving more to the north later today and tonight.
There is a definite deteriation in Bill's appearance this morning and
he has likely peaked. It does concern me that the new England Coast
and especially the Canadian Maratimes could see direct impacts from
the storm. It will be watched closely the next 24 to 48 hours to see
if he behaves as models say he will.

As mentioned yesterday, Bill will clear the tropics and things settle
as much they were before last weekend's tropical onslaught!

All for now!
