October has been quiet on the severe weather front in the southern Plains, but that is expected to change tonight. Large hail, damaging wind gusts and several tornadoes are possible.
A strong cold front will accelerate eastward across the central and southern Plains by this evening, igniting robust thunderstorms and possible flash flooding in northeastern Texas, eastern Oklahoma, Arkansas, and southern Missouri. This includes the Dallas-Fort Worth metroplex, Tulsa, Okla., Little Rock, Ark., and Springfield, Mo.
Tornado Watches have been issued for eastern Oklahoma, northeastern Texas, western Arkansas and northwest Lousiana, including Ardmore and Tulsa, Okla., Dallas and Tyler, Texas, Fayetteville and Texarkana, Ark., Shreveport, La., and Joplinh and Springfield, Mo.
These storms will be fueled by a clash between warm, humid air and cooler, drier air meeting along a cold front. This is fostering storm development this evening from near the Dallas-Fort Worth metroplex to just east of Oklahoma City. From there, the storms will multiply and converge into clusters or lines and rumble eastward across eastern Oklahoma, northeastern Texas, western Arkansas, and southern Missouri through early Monday morning.
The severe thunderstorms will have great potential to produce quarter-sized hail or larger. Dallas, Fort Worth, Arlington, Plano and Garland, Texas, to McAlester, Okla., and Fort Smith, Ark., all have the greatest chance for severe weather. In addition to hail, destructive wind gusts topping 60 mph and even several tornadoes could develop.
This part of the country hasn’t experienced severe weather since October 10, when there were more than two dozen reports. Hail larger than baseballs pelted White Settlement, Texas, while a gust of 65 mph was clocked in Cecil, Ark. A pair of thunderstorm gusts peaking at 61 mph were measured at Granbury, Texas, and near Eufaula, Okla., as well.
