Synopsis and Discussion
A strong Cold Air Damming (CAD) weather pattern has set up over the Triad, Monday. Cool high pressure over the NE US has ridged down the east coast while warm, moist air, from a series of disturbances to the SE of NC, rides over the cool dome resulting in cloudy skies and periods of cool rain. Thus far, the rain hasn't overcome the slightly elevated code YELLOW particle pollution readings, Monday. Continued rain, which will increase in intensity through Tuesday, will help to push particle pollution values lower and code GREEN. The CAD regime will persist, Wednesday, as low pressure, spinning to the west of the state, will swing another batch of rain, into the region, helping to keep particle pollution lower and code GREEN. A few lingering showers are still possible, Thursday, as the rain and dense clouds finally exit the state. Particle pollution will contine in the GOOD range, Thursday. Ozone will be very low and code GREEN throughout the forecasting period (GENTRY).
