PHOENIX -- There were a limited number of thunderstorms around Arizona on Friday afternoon, and we expect the decline in the number of storms to continue through at least Saturday.
By Sunday night and Monday, we anticipate an upswing in the monsoon with the chances for rain in the Valley picking up slightly.
The weekend will feature rather hot temperatures, with highs Saturday and Sunday around 110 degrees.
Models indicate the dry air will not make much more headway eastward, generally stalling somewhere across central Arizona. However, we do think this will mainly keep thunderstorm chances for today over higher-terrain areas north and east of Phoenix.
A weak southwesterly steering flow should keep any storms that do fire over the high terrain from moving into the lower deserts.
Similar conditions will exist for Saturday, though monsoon activity will be even more suppressed and generally confined to southeast Arizona as the dry air infiltrates all but southeast and east central Arizona.
High temperatures will get a boost due to the drier conditions, with highs reaching around normal for today and likely peaking out around 110 in the hottest spots on Saturday.
