"Triple Point" Becoming Active

Cumulus clouds (a precursor to thunderstorm development) are organizing near the "triple point" (intersection of a surface low pressure center, dryline and warm front) across north-central Oklahoma.  See the latest visible satellite image above for greater detail.

Thunderstorms can be expected to develop in this region during the next 2 hours and move East/Northeast with time.  Large hail is likely, and isolated tornadoes are also possible.

A Tornado Watch has just been issued for the region until 9 o'clock tonight.
