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. By Tuesday, light snow can be expected for the higher elevation areas in Arizona and New Mexico. Cold, autumn area currently sweeping across the central and southern U.S. will continue pressing east as a strong cold front presses eastward over the southern Plains and Mississippi Valley. High temperatures on Monday will hover in the mid 40s to low 50s across most of Texas (with exception to the Texas Gulf Coast). These temperatures will be nearly 30 degrees below average. By Tuesday, as the cold front exits the East Coast and stretches from the Southeast to the western Gulf of Mexico, cooler temperatures will also settle from the Northeast, Ohio Valley to the western portions of the Southeast.
