Forecast Discussion: Updated Friday, April 24, 2015 10:55 a.m. After a chance of some lingering showers this morning and early afternoon, followed by fair skies by tonight, another more vigorous Pacific Northwest low pressure system will move into the state this weekend. This next system is expected to have stronger winds with gusts 25-30 mph on Saturday and possibly 30-35 mph on Sunday. The chance for additional shower activity will be present late Saturday through early Sunday. The likelihood of widespread blowing dust exists for the second half of Saturday through Sunday (depending on the amount and location of rain). The PM10 AQI forecasts are in the upper good to mid/upper range of the moderate AQI categories for Saturday and Sunday. The forecasts are holding just below the PM10 health watch criteria. Check back on the weekend to see if an updated air quality forecast is necessary. A warm up will take place next week with afternoon high temperatures expected to approach the century mark by mid week. Ozone will be the pollutant of concern most likely next week. Stay tuned.
