Concerns for flash flooding are increasing along the I-20 and I-30 corridors around the DFW Metroplex overnight. Widespread heavy rainfall and embedded thunderstorms will continue through the overnight hours and flooding is likely to become more widespread. If you are traveling, use extra caution as it is especially difficult to identify flooded roadways at night.
A Flash Flood Watch is is in effect thru Saturday afternoon for parts of the area. Widespread heavy rain is expected, especially near and northwest of a Stephenville to Denton to Sherman line. The most likely time frame for widespread heavy rain and Flash Flooding will be tonight into Saturday morning. Rainfall totals will generally be in the 2 to 4 inch range, with isolated higher amounts of closer to 6-8 inches possible.
Widespread showers and thunderstorms will be ongoing this evening and tonight across most of North and Central Texas. Rain will be heavy at times with flash flooding possible. Gusty winds and cloud- to-ground lightning will also be possible. A Flash Flood Watch remains in effect through Saturday afternoon.
An upper level disturbance along with a cold front and abundant moisture will lead to numerous showers and a few thunderstorms on Saturday. Heavy rainfall will be the main threat along with some flooding of low lying areas. The heaviest rainfall is likely along and north of I-20. There will be a low threat for severe weather Saturday afternoon, and we'll continue to monitor this potential.
Rain chances will continue on Sunday, but are lower than previous days. The best rain chances will be across the eastern counties. Highs will be in the mid 70s to mid 80s.
Here are a few flash flood safety tips. Be cautious of areas that are prone to flooding and be especially cautious at night when it's harder to recognize flood dangers. Never drive through flooded roadways!
Astronomical Fall starts this Saturday September 22nd. On this day, both hemispheres receive the same amount of radiation. Day and night are nearly equal in length (approximately 12 hours). Days will slowly become shorter and nights will be longer.
