Forecast Discussion:
Rain chances are looking better and better as we move through the week, with multiple shortwaves providing moisture to the state at the end of the week. Chances for rain will occur Thursday and Friday, with better chances for rain on Friday for the southern half of the state.
Localized blowing dust will be possible as winds increase before both systems enter the region, with PM10 levels forecast to be highest on Thursday. If we're lucky and models hold, particulate matter pollution will improve dramatically this weekend thanks to rainfall on Friday. Let's hope this system follows through!
After this week, more chances for precipitation will be possible thanks to an active jet stream. After our seemingly endless dry spell starting at the end of last summer, it is crucial that we get some rain here soon to help out the dried soils and fuels here in Arizona.
Check in tomorrow for the latest.
