A potent storm system will bring scattered strong to severe thunderstorms across the region, potentially in multiple rounds. The first storms, should they develop, will be very isolated in nature (20 percent chance) across northeast Texas Monday evening. More widespread thunderstorm development is expected Monday night, particularly after midnight, across central and north-central Texas. Thunderstorms Monday evening into the overnight hours will bring the potential for frequent lightning, small hail, and gusty winds. Tuesday, storms will move west to east, generally strengthening as the morning continues. Storms may become severe sometime Tuesday morning near or just east of the I-35 corridor. Severe weather threat will increase with eastward extent, and will be maximized towards the Arklatex region. The primary hazards at this time appear to be large hail and damaging winds, though a tornado or two can't be ruled out. There are still some uncertainties with details regarding timing and hazard magnitudes, so please check back for further updates to the forecast this weekend.
