PHOENIX — Get ready for some big weather changes across the state later this week.
Heading into Wednesday the Valley will stay dry and warm, with highs well into the upper 90s across the Valley with a few cities reaching 100 degrees.
What’s coming next, however, could bring record amounts of tropical moisture to the Arizona.
Here is the breakdown...
Moisture from the remnants of Priscilla will start moving in from the south, pulling in higher humidity and even a few afternoon showers across eastern Arizona as early as Wednesday.
A Pacific storm system will also move in from the northwest, and the combination of these two systems could lead to several days of rain.
Starting Thursday and going through the weekend with Friday and Saturday looking to bring our best chances for widespread and heavy rainfall.
Isolated thunderstorms are possible, bringing strong gusty winds, small hail, lightning and brief heavy downpours.
Models are not in great agreement as for the amount of rainfall.
Some areas could get only a quarter of an inch to a half an inch of rain. Others could pick up one to two inches of rain with isolated pockets of up to three inches of rain.
This means Flash Flooding is a BIG concern around the state.
With several days of rain expected, dry washes and small creeks could start flowing and some low-lying spots may flood as well.
The wet weather pattern will also cool us down quite a bit!
Highs will fall into the 80s by the weekend, which is roughly five degrees below normal for this time of year.
