Forecast Discussion: Updated Friday, September 19, 2014 10:15 a.m. Today and Saturday will be the last few days with abundant atmospheric moisture. Additionally, each day will feature chances for scattered thunderstorms and with that the possibility of strong outflow winds. Thankfully most areas have received sufficient rains over the past couple of weeks so blowing dust will be minimal. That said, have added the word “DUST” to the forecast as a reminder that strong outflow winds from thunderstorms can cause significant localized blowing dust. Atmospheric conditions will dry out on Sunday and into early next week. A Pacific low pressure system will skirt by northern Arizona early next week and for the local area mean very little. The winds should be light enough to not cause a significant increase in the dust levels for the beginning of next week and will last into the middle of next week. The PM10 levels will slowly rise each day due to the ground conditions drying out along with elevated weekday dust causing activities. A Pacific Northwest low pressure system will move into the southwestern United States late next week and will bring cooler temperatures and stronger winds. Forecaster – S. DiBiase
