.DISCUSSION...

...Thunderstorms in High Terrain and Southern Plains Today...
...Increasing Thunderstorm Activity This Week...

Isolated to scattered thunderstorms will develop over the higher
terrain this morning, and spread across southern zones this
afternoon/evening. Northern zones will see little chance of
precipitation. Minimum RH values are expected to be higher today,
with cooler temps and increased cloud cover. Light northerly winds
are expected to prevail through the day. Humidity recoveries will
be better tonight, as winds turn east and southeast, bringing
monsoonal moisture into the area. More showers and thunderstorms
are expected Wednesday, bringing improved CWR to much of the
region. Unsettled weather will continue through the week, as a
series of systems bring increased thunderstorm chances, more
seasonable temperatures, and higher humidities. AAG
