.DISCUSSION...
KEY MESSAGE 1...

Mid level shortwave energy will dive south into the area into the
afternoon hours, followed by a cold front late this evening into the
overnight. As a cluster of elevated convection associated with this
shortwave approaches our area, it will encounter a very moist and
unstable environment, with convection becoming more surface based as
it enters our CWA. CAPE values progged to approach 2000 to 4000
J/kg, and increasing shear values of 40 to 60 kts in the 0-6km
layer, will result in potential for storms to become organized.
Damaging winds are the primary hazard, with convection potentially
organizing into lines/bowing segments, but with that being said,
there is a tornado threat as well, with low LCL heights less than
1500m and 0-3km SRH greater than 250.

Timing of the severe activity is difficult to pinpoint, but appears
most should occur in the afternoon to early/mid evening hours, with
an additional round of convection expected with the front later
tonight. It's possible some of this convection associated with the
front could be low end severe, but with loss of heating, and any
effects earlier convection has on the overall environment,
confidence isn't high.

Lastly, with any storms that occur, flash flooding is a possibility,
with the overall anomalously high PW are that continues to remain in
place. This should mainly be a threat in locations that receive
repetitive rounds of convection.

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
Heavy rain and strong thunderstorms will continue to produce
IFR flight conditions at times this evening. Although activity
will continue to taper off from west to east tonight, IFR or
worse conditions are expected to develop in fog and stratus.
CIGs/VIS will slowly improve to VFR after 12Z Wednesday.

Expect moderate southwest winds, with stronger gusts in storms
this evening. Flow will then become calm to light out of the northwest
after a front crosses the area tonight.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z THURSDAY...

FORECAST CONFIDENCE: Medium

ALTERNATE SCENARIOS: Impacts due to thunderstorms could vary.
