Additional Rain and Ongoing Flooding in Texas; Snow in the Southern Rockies

The heavy rain in central Texas will shift slightly providing some relief to flood ravaged areas. Flooding and flash flooding will still be possible across portions of Texas. An upper level low will move east from southern California, which will allow California offshore winds to ease reducing fire weather threats. As this system moves east, snow will increase across the Southern Rockies. Read More >

Several days of rainfall have led to several areas seeing 5 to 7.50 inches of rainfall since 6 PM last Friday evening through 6 PM this evening. Today's daily rainfall generally ranges from 0.5 to 1.5 inches (ending at 6 PM as well). The above graphic details the swath of heavier rainfall, but is overestimated many areas south of I-20 due to hail contamination from severe storms over the weekend. A Flood Watch continues in effect for this swatch area through 7 AM Wednesday morning.
An areal flood watch has been extended through 7 am CDT Wednesday for the green-shaded area. An addition 1-2 inches could fall across a few areas within the watch overnight. Soils are supersaturated and any additional, even brief moderate to heavier rain will run off and flood typical low-lying areas or exacerbate ongoing river and creek flooding.
Light to moderate rain and cool temperatures will continue through the remainder of the work week for North and Central Texas. Cloud cover and rainfall will keep temperatures from warming significantly but most areas will see slightly warmer temperatures by the weekend. New rainfall totals of 1-3" will be possible so ongoing flood issues may continue for several days.
