the Southern Plains and Lower Mississippi Valley...

At 900 AM CDT...Pacific moisture associated with former Tropical
Depression 19-E combined with moisture from the Gulf of Mexico
continues to allow for an impressive axis of moisture to impact
portions of the Southern Plains and Lower Mississippi Valley.  At
the surface, the center of a low pressure system with a sea-level
pressure of 1011 mb or 29.86 inches was located just east of Fort
Worth, Texas.  From this low, a slow-moving cold front stretched
south and westward through central Texas, while a stationary front
extended through northeastern Texas into Arkansas and attached to
a cold front moving through the Ohio and Lower Mississippi
Valleys.  National Weather Service radars and surface observations
indicated that moderate to heavy rain was widespread throughout
southeastern Oklahoma, central and northern Texas, much of
Arkansas, and into portions of the Ohio River Valley.  Meanwhile,
bands of thunderstorms with heavy downpours were moving eastward
across eastern Texas into western Louisiana.

The low pressure system and associated fronts are forecast to move
slowly southeastward through Texas over the next couple of days.
The slow-moving nature of the system will result in heavy rain to
continue across the Southern Plains through Sunday, with rainfall
totals of 6 to 10 inches over northern Texas and southern Oklahoma
in particular, with local amounts in the 15-20 inch range
possible. This would be similar to other tropical cyclone
remnant-related events from Norma 1981 with 18.71 inches at
Kingston 4 SSE OK...Tico 1983 with 16.95 inches at Chickasha OK...
and similar heavy rain events from September 28-October 2, 1927
with 14.59 inches at Dutton AR... October 19-24, 1908 with 16.23
inches at Meaker OK...and October 11, 1973 with 15.68 inches at
Enid OK. For the rest of Saturday into Sunday morning, a MODERATE
RISK is in effect for portions of northeast Texas and including
the Arklatex. Additional rainfall amounts of as much as 3 to 5
inches, with locally higher amounts are expected over this region,
with the rainfall also overspreading adjacent areas of the Lower
Mississippi and Tennessee Valleys through the weekend.

The next storm summary will be issued by the Weather Prediction
Center at 400 PM CDT. Please refer to your local National Weather
Service office for additional information on this event.
