...ACTIVE WEATHER PATTERN THIS WEEK WITH THE THREAT FOR MULTIPLE
   ROUNDS OF SEVERE WEATHER...

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...Today and Tonight.

DISCUSSION...
A few rivers remain in flood across eastern Oklahoma. Refer to
the latest flood statements /OKCFLSTSA/ issued by the National
Weather Service in Tulsa. Otherwise, no hazardous weather is
expected through tonight.


SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
MONDAY...High Wind Potential.
TUESDAY...Severe Thunderstorm...High Wind and Heavy Rain Potential.
WEDNESDAY AND THURSDAY...Severe Thunderstorm Potential.
FRIDAY AND SATURDAY...Thunderstorm Potential...Heavy Rain Potential.

EXTENDED DISCUSSION...
Strong southerly winds will begin to increase Monday ahead of an
approaching upper level disturbance on Tuesday. A strong cap will
remain in place for much of the day Tuesday suppressing thunderstorm
development. The cap should weaken late Tuesday afternoon or Tuesday
evening with scattered thunderstorms developing as a cold front
moves into northeast Oklahoma. Any storms that develop will likely
be severe with the main threat of very large hail and damaging
winds, although a tornado or two can not be ruled out. The severe
threat should end Wednesday morning as the line of storms shift
east.

A stronger storm system is expected to move into the four corners
region by late week, impacting the area Friday and Saturday with the
threat for more widespread and significant severe weather. A few
elevated storms will be possible Friday morning as a warm front
begins to lift north. Multiple rounds of severe weather will be
possible Friday and Saturday before a Pacific front moves through
Sunday morning. Large hail and damaging winds will be likely,
including the threat for tornadoes. In addition, locally heavy
rainfall is expected which could lead to flash flooding.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Overall timing and specific severe weather threats will continue
to be refined in the coming days as additional data become
available.
