PHOENIX — A trough will begin digging in Wednesday, finally pushing our blockbuster high pressure eastward. As a result, temperatures will lower but are expected to still stay in above average territory.
Winds will also race in from the southwest and even drier air will be on deck. This setup will yield critical fire weather conditions, prompting for a fire weather watch in northwestern Arizona on Wednesday and Thursday.
Southwest wind gusts could jump to around 35 mph with relative humidity values sinking between 4-9 percent. Any fires that spark will likely spread rapidly. Outdoor burning is not recommended during this time.
Southeastern Arizona and the White Mountains will be more resilient to the invasion of dry air and could still see the eruption of some afternoon monsoon showers and thunderstorms the remainder of this workweek and weekend.
