***Stormy weather for the southern Plains and Inter-Mountain
West***

***Coastal low pressure near the southeast coast this weekend***

***Warmer weather for eastern U.S. before next cold front
arrives***

After all of the rain and flooding from the remnants of Hurricane
Odile, lingering moisture over Texas will keep the threat of
locally heavy rainfall and flooding going through Sunday, although
the areal coverage should be less than what has recently been
observed.  Anomalous moisture is also expected over the
Four-Corners region and westward to Nevada, where showers and
storms will also be scattered to occasionally numerous.

Over the coastal waters of the southeast U.S., a surface wave of
low pressure has developed on a stationary front that currently
extends over the Florida peninsula.  This low should slowly
migrate towards the northeast just offshore of the Carolina coast
tonight and early Sunday.  By Sunday night, the system should
track towards the Gulf of Maine.  Current forecasts indicate the
bulk of the precipitation will remain offshore, but occasional
showers and light rain will affect the majority of the immediate
East Coast shoreline.

Across the eastern U.S. this weekend, expect a brief return to
warmer than average temperatures ahead of the next storm system to
the west.  The departing surface high off the East Coast will
cause the winds to veer towards the south and southwest, ushering
in a warmer and more humid airmass.  The highest temperatures for
the East Coast are expected on Sunday, when widespread readings
well into the 80s are likely from southern New England to Florida.
 A refreshing change to fall-like weather will resume early next
week as another quality airmass settles in behind the cold front.
