Here's our latest thinking on storm timing Late Saturday PM into Early Sunday AM. Storms will initially start out to the northwest in the early to late evening hours on Saturday. Initial storms may pose a tornado and hail risk, but the primary hazard will be damaging winds. Thereafter, they will likely grow upscale into a line of storms, resulting in mostly a damaging wind threat. There will be an enhanced threat for brief spin-up tornadoes within the line as well as the potential for an enhanced hail and tornado threat IF storms can develop ahead of the line. For midnight and beyond, most activity should be in the form of a squall line promoting a continued risk for damaging winds. Brief spin up tornadoes cannot be completely ruled out as well as a threat for hail.
Rain chances are low this afternoon and evening, but there are three opportunities for convection. This afternoon, some showers and storms are possible east of a Cooper to Corsicana to Cameron line. A cap should limit the extent of storms, but with considerable instability, any storms that are able to develop this afternoon could quickly become severe with large hail and damaging winds. An isolated tornado cannot be ruled out. Late this afternoon and evening, some thunderstorms may form along a dryline to our west and could move into areas west of a line from Gainesville to Weatherford to Stephenville. These storms could potentially be severe with a threat for damaging winds, hail, and possibly an isolated tornado. Finally, a line of storms, likely severe, will start moving in from the northwest late this evening.
A series of cold fronts will shape the temperatures the next several days. After a cloudy start to the day today, the sun will warm temperatures into the 80s. It will be the last humid day for a while as a cold front will move through the region tonight, bringing with it widespread thunderstorms, some of which may be severe. The sun will re-emerge, and Sunday will be mild but breezy. Temperatures will reach 80 degrees in some locations on Monday before the next front arrives. A warming trend through the middle of the week will get afternoon temperatures back into the 80s by Thursday. A stronger cold front will arrive late in the week, bringing with it the next chance for rain.
Here is some information on Wireless Emergency Alerts (WEA). Take time to review this information as we prepare for severe weather across the region!
