Forecast Discussion: Updated Thursday, July 31, 2014 11 a.m. ** PM10 HEALTH WATCH IN EFFECT FRIDAY, AUGUST 1, 2014 ** A difficult air quality forecast is in store for today and tomorrow as a complicated weather setup adds a level of uncertainty. A Mesoscale Convective System (MCS) (i.e. a large area of active weather) over northern Mexico yesterday afternoon moved northward into southern Arizona last night and by this morning had reached southern and eastern Pinal County. Light sprinkles and showers took place in those areas during the early to mid part of this morning but have since dissipated. The instability in the atmospheric conditions today will keep the chance for storm development into late tonight. One area of concern is the mountains to our north where storm development is expected to take place this afternoon/evening. Some of this storm activity is projected to make its way south and into the desert locations. Strong outflow winds and blowing dust is anticipated to move from north to south and make its way through the Phoenix metro and into the county this evening. Therefore today’s PM10 AQI forecast has been increased into the middle of the moderate category. Friday is expected to be another active weather day with storm development over the mountains to our east moving westward into the county. Stronger outflows (as compared to today’s expected outflows) and associated blowing dust in central and western areas of the county are expected. Therefore as a precaution, a PM10 Health Watch has been issued for Friday. Anyone with respiratory and/or heart ailments should remain indoors during Friday afternoon/evening when blowing dust is likely. The storms on Friday afternoon/evening are expected to bring measurable rain to the central and western areas of the county. Therefore the forecasted PM10 levels for this weekend have been lowered. Keep tabs and check back on Friday for an updated air quality forecast. Forecaster – S. DiBiase
