EXTENDED DISCUSSION...

An active weather pattern will develop this week with
multiple rounds of severe weather, including the potential
for heavy rain and flash flooding.

A strong cap will remain in place for much of the day Tuesday,
suppressing thunderstorm development until early evening as the
cap finally begins to weaken. Scattered strong to severe thunderstorms
will develop as a cold front moves into northeast Oklahoma. Any
storms that develop will have the potential to be supercells with
large hail and damaging winds the main threats. Tornado potential
is expected to be limited. The severe threat will continue into
the day Wednesday across southeast Oklahoma and northwest Arkansas
before the convective line sweeps east of the area.

A stronger storm system is expected to move into the Four Corners
region by late week, with the threat for more widespread and significant
severe weather Friday and Saturday. A few elevated storms will be
possible as early as late Thursday night and into 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, especially on Friday, including the threat for
tornadoes. In addition, locally heavy rainfall is expected which
could lead to flash flooding and additional rises on area rivers.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Continue to monitor future forecasts and outlooks, especially
concerning the Friday and Saturday severe weather and flooding
potential. Overall timing and specific severe weather threats
will continue to be refined.
