.DISCUSSION...Thunderstorms in the vicinity of the Marzano wildfire
remain the main concern, with a 30-40% chance of thunderstorms
persisting through late this evening, and a 50-60% chance Wednesday
afternoon through Wednesday night. Moderate to heavy rain, erratic
gusty winds, and lightning will accompany any storm that develops,
with potential impacts from outflow even from distant storms. Given
increasing moisture, recovery will be good to very good, with min RHs
Wednesday and Thursday around 40%. Outside of convective influences,
20ft winds will generally remain terrain-driven, around 5-10 mph.
Ventilation rates will be marginal to good tonight through Wednesday
night, improving to very good on Thursday.
