.DISCUSSION...through Friday.

Early afternoon infrared and water vapor satellite imagery shows
elongated troughing across the Southwestern US from the shortwave
that dropped into the area last night. This shortwave was
responsible for the overnight uptick in north winds across the
region. These winds will gradually decrease throughout the afternoon.
 In addition to breezy north winds, Mohave County will see isolated
showers and thunderstorms as this trough lingers across the area
today. For the most part precipitation will be light. However, with
the cold air aloft and lingering moisture, stronger storms will be
capable of producing moderate-to-heavy rain. Nuisance flooding and
isolated instances of flash flooding will be possible.

Weather will calm down heading into next week as the trough exits on
Sunday. Dry conditions and seasonable temperatures are on tap for
the first half of the week. Guidance continues to show the weather
pattern becoming more active late next week as the subtropical jet
draws moisture into the Southwestern US. Cluster analysis shows
several variations of offshore troughing during this time, so there
remains a fair amount of uncertainty, but there appears to be a good
signal for the existence of an offshore trough and southwesterly
flow over us. Should this come to fruition, we should see an
increase in southwest winds and low to moderate (10-50%)
precipitation chances around Halloween weekend.
