Breezy southerly winds, with showers and storms area-wide in the morning shifting to areas off the Caprock by the afternoon. A few of the storms could be strong to severe, or produce scattered flooding, off the Caprock this evening.
Renewed development of heavy showers and storms is possible Wednesday evening through the early morning hours on Thursday. Storms will be capable of producing large hail, damaging winds, isolated tornadoes, and flooding from heavy rainfall.
Showers and storms off the Caprock may produce localized rainfall amounts of 1 to 3" through Wednesday night. This may lead to isolated flash flooding. Never drive across flooded roads!
Storms will shift to areas off the Caprock Wednesday, some of which could be strong to severe and produce swaths of 1 to 3" of rainfall. Sporadic damaging winds and isolated flash flooding are the main concerns, although a tornado cannot be ruled out.
A broken line of showers and storms is expected to develop somewhere across the Rolling Plains. The potential for heavy rain increases with southeastward extent, with about a 50% chance for over 1" of rain across Stonewall County. This may lead to isolated instances of flooding.
The start of October will feature slightly cooler than normal temperatures, with decreasing rain chances (although a few light showers can't be ruled out Thursday night into Friday). Northerly winds are expected on Thursday, with gusts as high as 30 mph at times.

 

 

 

Local Weather History For September 30th...
2004: Scattered to numerous thunderstorms exited eastern New Mexico late this day and generated several cases of flooding
across the southern South Plains and southern Rolling Plains. Several roads from Brownfield east to Jayton and Guthrie had
to be closed due to impassable volumes of water. Ten miles west of Tahoka, flash flooding washed a car off the road on
Highway 380. In Post, several vehicles became stranded in several feet of water.
