Phoenix weather: Drying out

PHOENIX -- We should see some drier weather through the weekend with a slight warming trend.

From the National Weather Service discussion:

A drying and warming trend will begin today and continue into Friday as high pressure rebuilds over the region. A very slow increase in moisture and chances for thunderstorms will begin late Friday and continue into the upcoming weekend.

Next week, the upper level flow aloft becomes more southeasterly over the desert Southwest.

A very gradual increase in southeasterly flow is expected to allow moisture to slowly seep northward into the region from late Friday onward into the weekend.

A further increase in moisture is then expected early next week as tropical depression 15e, which is expected to become tropical storm Odile later today, moves northwestward just off the West Coast of mainland Mexico.

This should allow at least isolated showers and thunderstorms to return to the higher terrain north and east of Phoenix on Friday afternoon, with slight chances for thunderstorms returning to the deserts next week.

However, we are not expecting anything like we saw this week at this time, since weather models keep Odile and most of its moisture well offshore.

Also, the fact that the upper-level ridge axis will be remaining pretty much overhead during the whole time will likely serve to inhibit the development of showers/thunderstorms.
