Training Continues…3pm

The SPC has placed southwest Oklahoma, including most of the CASA domain, under a Severe Thunderstorm Watch until 03 UTC. The outflow boundary has zipped up with a pre-frontal trough from Shattuck to Mangum, OK. Scattered CBs have formed off and on in this zone…but none have quite taken hold, as convergence and lift remain quite shallow. Other thunderstorms have begun to sustain themselves farther south along the trough axis into Texas. Opportunity for more robust convective initiation should increase up into Oklahoma with additional heating/destabilization. Water vapor imagery also hints at the influence of a short wave ridge exiting western Oklahoma…with a more diffluent upper flow pattern approaching from eastern New Mexico/West Texas.

The forecaster/evaluators have switched places so that both sets of two will receive training on both the PAR and CASA experiments. The Oklahoma IOP will either begin at 4pm (WDSS training on the fly) or 5 pm (WDSS traning at 4pm).
