Update from Jeff:

Storms starting to congeal into a forward moving line along/N of I-10. Starting to see radar DBZ weakening suggesting hail sizes may be decreasing. Additionally, supercell sturcutres appear to be weakening as well suggesting a lowering hail threat. Damaging wind threat may increase next 30-45 minutes along US 59 corridor as storms gust out.

A lot of reports of hail over NW/N/C Harris County in the last 2 hour from tennis ball size to marble size. Cores of greater than quarter size hail have likely produces swaths of property damage.

Note: Storm over Colorado County near Columbus is producing golfball size hail along I-10…just reported by DPS.
