.SYNOPSIS...Warm and dry conditions are expected for the start of
the week. Expect breezy and cooler weather from Wednesday through
Friday, with chances for showers and thunderstorms. Dry conditions
develop again for the weekend.
&&
.DISCUSSION...A slow moving trough will meander through the western
states for the next week or so, significantly changing our weather.
Ahead of the trough, much drier mid-level air has moved into Arizona
today and has capped the atmosphere. High hghts and anti-cyclonic
flow will transition to lower hghts and cyclonic flow as early as
Tuesday. This also means increased southwest winds, especially
Wednesday and Thursday, as the trough moves into the Great Basin.
The trough may tap into some of the remnant monsoonal moisture pool
by mid-week, which could lead to some stronger thunderstorms. The
best chance for this moisture tap looks like eastern Arizona. The
bigger story is the winds, which may top 40 mph by Thursday, this
will be the most wind seen in some time. Fire danger isn`t horrible
right now, but this pattern will need to be watched.
By next weekend, the trough ejects and winds will come down. The air
mass trailing the trough will be quite dry, so expect a sunny and
seasonably cool weekend.
