...Flooding and severe weather possible across the southern Plains...
...Cold autumn air will spread across the central and eastern U.S...
An active pattern will continue across the southern Plains and into the
lower Mississippi Valley as a elongated trough digs across the
western U.S. This trough will pull tropical moisture across
these regions--giving way to showers and thunderstorms from the Big Bend
to the Arklatex region. Overnight and into tomorrow morning, showers and
thunderstorms will develop across the central Texas region and is expected
to produce heavy rainfall--notably in West Texas near the Big Bend and
into north Texas. There is a slight risk of flash flooding along with
severe weather with this activity. Another round of thunderstorms will
develop later into Monday and continue into Tuesday across central Texas
once again--with a slight risk of flash flooding possible. However,
severe weather is not expected on this day. By Tuesday evening,
thunderstorms may continue along the eastern portions of the Red River
Valley but begin to taper off across west and central Texas.
Heavy snow that has impacted most of the Rockies and Plains will continue
today. However, by tonight and tomorrow--most of this activity will come
to an end. Light snowfall will still occur in the southern Rockies and a
small portion of the central Plains into the middle Mississippi Valley.
The Upper Great Lakes can also expect very light snow.
As a strong cold front sweeps across the western and central U.S.,
cold temperatures will follow. On Sunday, high temperatures will
not escape the low 40s across the northern and central Plains in
addition to the Upper Midwest--which are 20 to 30 degrees below
average. As the cold front presses eastward over the southern
Plains and Mississippi Valley, high temperatures from the
Dallas-Fort Worth region to the Big Bend will settle into the
mid-upper 40s. Similar temperatures will also be felt for the
middle Mississippi Valley.
