Showers and thunderstorms will continue across much of the area this afternoon. A Marginal Risk (Level 1/5) for severe weather remains in place for our nearly the entire Four State Region, save for our southwesternmost zones of deep east Texas. Damaging winds and large hail look to be the primary associated hazard with these storms. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. The next organized severe weather threat will develop on Saturday, with areas along and north of the I-30 corridor included in a Marginal Risk (Level 1/5) and our extreme northern zones in a Slight Risk (Level 2/5). Damaging winds and hail look to be the primary associated hazards with these storms, as well as brief periods of heavy rainfall. Thunderstorm chances continue on a near-daily basis through the course of the coming week, with the best chances for stronger storms being across the northern and eastern zones of the CWA, into southwest Arkansas and parts of north & central Louisiana. Temperatures are on track to climb back into the mid to upper 90s late this weekend and into next week. .SPOTTER INFORMATION STATEMENT... Spotter activation may be needed.
