.SYNOPSIS...
Dry and tranquil weather is expected to continue through this
weekend and next week. A couple weak and dry disturbances will
pass by early next week in between periods of high pressure
ridging. Otherwise, above normal temperatures, with highs mostly
in the low to mid 70s, light winds, and periods of high clouds
will prevail.

.DISCUSSION...
Dry and tranquil weather conditions will continue on through much
of the next couple weeks with no indications of when the next
considerable chance of rain is. At the moment, strong NW flow
continues across the Southwest with strong high pressure between
here and Hawaii. Thinner clouds and less coverage of clouds will
allow for temperatures to be a bit warmer than yesterday,
especially across central AZ. Noon temperatures are running 2-5
degrees warmer than they were yesterday. Heading through this
weekend temperatures are expected to warm a little further, as
the high pressure nudges further east into the region, with lower
desert highs increasing into the middle 70s by Sunday. While
afternoon highs warm up to 10 degrees above normal, morning lows
will remain closer to normal and quite cold in some valley
locations like Casa Grande.

The ridge over the Desert Southwest will eventually be flattened
and dissipate following a couple dry troughs moving through the
West. The first will pass well to the north, through the Great
Basin, on Sunday and the second is then likely to pass a bit
closer to our region Tuesday. With the latest NBM forecast, these
troughs are expected to lead to to temperatures dropping a few
degrees for Tuesday into Wednesday. The pattern then essentially
repeats itself during the latter half of next week with another
ridge (likely stronger) building over much of the Western U.S.
Guidance is now hinting at highs potentially reaching above 75
degrees across portions of the lower deserts at some point late
next week into the following weekend.
