.SYNOPSIS...Seasonable daytime temperatures, lighter winds, and
dry conditions are expected through mid week. Expect low storm
chances to return to areas from the Mogollon Rim southward by
Thursday, with chances increasing and spreading northward over
the region for Friday and Saturday.

.DISCUSSION...Quiet weather is expected around northern Arizona
through mid week as the low that brought storms to eastern parts
of the state Friday into early Saturday is moving into the plains
states this morning. Much drier air left in the wake of the system
will remain over our area for the next several days, with light
westerly flow. Daytime temperatures will be within a few degrees
of average for mid September. Overnight lows will be chilly in the
high country the next couple days with the dry air mass in place,
dipping near freezing at the usual cold spots (Tusayan, Bellemont,
Ft Valley) and into the 40s for places like Prescott and Winslow.
High pressure over northern Mexico up into California is forecast
to shift eastward later in the week as a low remains off the
coast. This should cause a more southerly flow into Arizona
helping advect deeper moisture northward. Ensemble mean
precipitable water is still showing a significant increase by
Friday/Saturday. Low shower and thunderstorm chances (10-20%) are
in the forecast Thursday from the Mogollon Rim south, increasing
to 30-60% by Friday and Saturday over the region. There is still
uncertainty in this pattern and the amount of moisture that will
be present in our area as ensemble model clusters show east-west
variation in the position of the offshore low - and this will
impact moisture availability. Stay tuned for updates.
