.DISCUSSION...through Tuesday.

Above normal temperatures and dry conditions will continue through
Friday. A ridge of high pressure will be the main feature through
Thanksgiving with a weak interior shortwave dampening the ridge on
Friday. The only noteworthy item will be northerly winds, down the
Colorado River Valley, particularly each afternoon through Thursday
afternoon. While these winds will remain 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.

The global ensembles are struggling with many of the details from
the weekend into the start of next week. The pattern will become
more unsettled but outside of the EPS, the GEFS and CMC have trended
more progressive and interior with all of the ensembles struggling
with timing. The most confidence is with regard to lowering
temperatures falling on average 10 degrees by Sunday and remaining a
few degrees below normal through Tuesday. Winds will also increase
across the area, particularly with north winds behind each
shortwave. Far less confidence with regard to precipitation but with
the more interior trajectory favoring the higher terrain of southern
Nevada and northwest Arizona.
