.DISCUSSION...through Monday.

Seasonal temperatures and dry conditions will continue through
Thanksgiving thanks to the ridge of high pressure building over the
Southwestern US. The combination of a weak shortwave ejecting into
the Northern Plains and this ridge shifting inland will result in an
enhanced pressure gradient, allowing for northerly afternoon breezes
today and tomorrow. The strongest of these winds are expected in the
lower Colorado River Valley around Laughlin/Bullhead City and
Needles. While these winds will remain well below wind advisory
criteria (sustained winds in excess of 30 mph or wind gusts in
excess of 40 mph), they will be enough to produce 1.5 to 2 foot
waves on Lake Mohave each afternoon resulting in hazardous boating
conditions for small water craft.

Our ridge of high pressure will begin to break down on Friday as a
shortwave begins to move through the Pacific Northwest. Beyond
Friday, forecast confidence decreases due to disagreements regarding
the timing and strength of a stronger trough that is expected to
impact the area. At a minimum, we can expect temperatures to
decrease over the weekend with an uptick in winds. As far as
potential precipitation goes, there remains a wide envelop of
possibilities at this time so make sure to keep an eye on the
forecast as this system could impact post-Thanksgiving travel plans
across the Southwest.
