***Fall-like weather across much of the nation***
***Moisture increasing for the Desert Southwest this week***
***Scattered showers and storms for the Gulf Coast***
A large surface high is controlling the weather pattern across much of the
country, with many states enjoying quality fall-like conditions. With the
surface high pressure covering most of the central and eastern parts of
the U.S., the majority of locations during this forecast period should
enjoy cool and dry weather.
Things will be different for the Desert Southwest through the middle of
the week with moisture on the increase again. Daily showers and storms
are expected each day from Arizona to western Texas with monsoonal
moisture flowing northward from Mexico. Of even greater importance is
moisture associated with Hurricane Odile, and this will be an issue later
in the week.
In the warm and humid airmass near the Gulf Coast and Florida, there will
be scattered showers and thunderstorms during the afternoon hours.
Locally heavy rainfall will be possible in areas where convective activity
is persistent. Showers are also likely across parts of the Great Lakes
region and Northeast U.S. as an upper level trough axis moves through the
