Downpours to accompany plunge of chilly air in south-central US into Tuesday

Crashing temperatures and rounds of rainfall are in store for the south-central United States early this week.
The region first got soaked by Sergio’s leftover moisture on Saturday, which also helped to trigger a few damaging tornadoes in Texas.
More rainfall is in store into Tuesday.
The heaviest rain is expected to stretch from the Big Bend of Texas to southeastern Oklahoma and Arkansas, where a total of 4-8 inches is possible.
The ground in this corridor is already saturated from an unusually wet September and first two weeks of October.
“Many locations from Texas to Arkansas received two to as much as five times their normal rainfall during the month of September,” Rathbun said.
As a result, any additional rainfall will quickly run off the wet ground, heightening the risk of flooded roads, fields and neighborhoods.
In addition to needing to watch out for high water on roadways, motorists should slow down to avoid the risk of hydroplaning along portions of interstates 10, 20, 30, 35, 40 and 45.
High temperatures will be in free fall as the downpours sweep through, being slashed by 20-40 degrees Fahrenheit within the span of 24 hours.
Shorts and t-shirts will need to be traded in for long sleeves and jackets.
As the cold air collided with lingering moisture, Amarillo, Texas, recorded a trace of snow on Sunday for the first time since April 25.
San Antonio will experience temperatures dropping from Sunday's high of 88 to the upper 50s on Monday.
Dallas may remain in the 40s on Monday and Tuesday after the weekend ended with a high of 80.

A gusty breeze from the north, combined with the wet conditions, will make it feel downright raw, with AccuWeather RealFeel® Temperatures expected to be in the 30s and lower 40s at times.
“Record-low temperatures could be broken in some places,” Rathbun said.
This includes in Oklahoma City and Dallas and Amarillo, Texas.
“Freezing temperatures can kill any outdoor plants or vegetation that is not properly treated or covered,” Rathbun said.
Conditions will trend milder during the latter half of the week, but downpours are likely to continue to pester the area.
