Current/Weekend weather in Flag/Sedona/Phoenix?

The NWS weather report is looking pretty ominous for this weekend through Tuesday for most of Arizona. My girlfriend and I are planning on leaving CA today and heading to Flagstaff and then Sedona... What's the weather looking like now? Any suggestions on which areas get the least chance of precipitation? If it made sense, we might even head towards Phoenix if there's a good likelihood it would be drier there (although the weather report doesn't look too stellar for Phoenix either).

Any suggestions? We've been waiting for this trip for a long time, and we want to make the most of it!

Thanks,
Scott

Rain!

It doesn't look like a very good weather for all the above. There is currently a hazardous urban rain warning in Phoenix (Scottsdale) and more rain and thunderstorms are expected over the weekend.

Flag says rain and snow for the weekend forcast.
Sedona says rain and snow at the 5500 level.
Tucson says scattered rain and thunderstorms.

Hope it works out for you.

A low pressure system is currently digging southward over the Western
U.S.,
bringing a cooler, less stable airmass towards Arizona. The system is
cutting off from the jet stream, which is currently located in Northern
Canada. Current forecasts indicate that the low pressure system will
stall
over the Southwest for the next few days, then slowly move eastward on
Sunday. However, cut-off lows tend to have more erratic
movement/development
than systems that are steered by the jet stream. Thus there has been
considerable inconsistency and uncertainty in the weather forecasts for
this
weekend.

What is certain however, is that we will see a cooling trend this
weekend.
Highs will be in the 60s today, dropping into the 50s on Friday and
Saturday. Overnight low temperatures will drop from the lower 40s
tomorrow
morning to around freezing on Sunday morning.

Current forecasts indicate that south to southwest winds will develop
today
through Friday, with sustained winds 10-25 mph, and higher gusts
possible.
The south wind will usher increased moisture into Arizona. This
moisture,
combined with lifting and cooler air aloft, will give rise a chance of
showers or thunderstorms this afternoon through Saturday (especially
over
Eastern Arizona and New Mexico).

Instability will be weak, but if thunderstorms form, moderate wind
shear
over Arizona will help organize them. Showers/thunderstorms that
develop
will move towards the north-northeast at around 20 mph, with gusty wind
and
small hail possible.

The best chance of showers will be Friday morning through early
afternoon.
