Some isolated showers may move into portions of our western zones this morning, but the main activity is still expected to arrive later today. Scattered showers and storms are anticipated this afternoon and evening mainly near and west of I-35. A few strong to severe storms are possible mainly for areas along and west of US-281 corridor. Heavy rain and damaging winds are the main threats, but we can't rule out some small hail and a brief tornado. Coverage of rain and storms will increase tonight with heavy rain and flooding as the primary concerns.
