Forecast Discussion: An upper level trough in the mid-latitude storm track – that is currently centered just east of Arizona – will move east on Tuesday as a ridge aloft briefly builds overhead from the west. Another trough is forecast to then develop along the west coast with Arizona positioned beneath its southeastern flank. For the Nogales area this means that low-level gradients will be sufficient for breezy to gusty winds each afternoon, followed by some enhancement of the winds Thursday thru Saturday. However, the risk for significant blowing dust and high PM-10 concentrations should remain low. Impacts from smoke due to the SOLDIER BASIN FIRE, located five miles east of the Nogales Airport, are currently expected to be minimal due to tall mixing depths, excellent dispersion, and a persistent westerly wind regime. However, during the overnight hours some smoke may reach the Nogales city limits due to topographical drainage effects. This situation will be updated as needed but for now the highest concentrations of both PM-10 (coarse particle) and PM-2.5 (fine particle) are forecast to remain in the good range of the Air Quality Index. |
