.SYNOPSIS...Seasonably warm temperatures will stick around today
and tomorrow, before cooler daytime highs return for the weekend.
Gusty winds forecast for Friday, with very slight chances for
showers/storms along the AZ/UT border. Milder weather looks to
return for the weekend and first part of next week.
&&
.DISCUSSION...High pressure remains focused across the Southwest
today, resulting in daytime highs 2-10 degrees above normal. Other
than warm afternoon temperatures, dry conditions and breezy winds
are expected today too.
Moving into Friday, an area of low pressure will move across the
Great Basin Region. This will cause pressure gradients to tighten
across Arizona and lead to gusty winds (35-45 mph). Strongest
winds will be north of the Mogollon Rim to the Coconino Plateau,
so we`ve issued a Wind Advisory for the corresponding zones for
Friday afternoon. These winds could create difficult travel
conditions for trucks/trailers, and any outside Halloween
decorations could be blown around if not secured. The core of this
system will stay north of the state, but a few sprinkles along
the AZ/UT border Friday afternoon/evening aren`t out of the
question.
Over the weekend, the trough will continue to move eastward and
limit gusty winds to areas near the AZ/NM border. Afterwards,
we`ll find ourselves under another weak trough pattern. This will
keep winds out of the south-southwest and mostly dry conditions.
We could see some moisture creep into the forecast towards the end
of next week, but confidence is very low at this time.
