Much needed moisture finally arrived in Arizona this past weekend, with anywhere from zero to over 2 inches of rain accumulation around the Prescott area. This rain has brought welcome relief to the extreme fire conditions that we have experienced, but until all areas are soaked by rain, fire danger still persists. Lightning can also ignite new wildfires if it strikes in areas that have not had much rain.
The lower atmosphere remains moist today for another round of possible showers or thunderstorms. Expect thunderstorms to develop over the higher terrain, then slowly drift eastward this afternoon and evening. Tomorrow through Thursday, slight drying of the atmosphere is anticipated as the upper-level ridge flattens and light westerly wind brings in a slightly drier airmass. However, there will continue to be a chance for thunderstorms.
By Friday, the upper-level high pressure will reestablish itself over to our north and east over Utah and Colorado, bringing a more humid airmass back across the state and increasing the likelihood of daily thunderstorm activity.
