While the next week will be active here in the state of Iowa, the weather will also be active across the rest of the country.
A low is forecasted to move from eastern Colorado east southeastward into northern Oklahoma as a dryline moves quickly eastward across the southern Plains on Friday. The models are in agreement with storms developing east of the dryline Friday afternoon and moving these storms quickly eastward across eastern Oklahoma and northeast Texas during the late afternoon and into the Arklatex during the evening.
The dynamics will make conditions favorable for severe storms and an organized wind-producing line segment possible. Moisture return is forecast to strengthen by Friday evening suggesting any severe convective line could become more organized with time as it moves eastward. The models still agree that the line should reach the lower Mississippi Valley by sunrise Saturday.
On Saturday, storms will slow down, which will keep the attention on the lower Mississippi Valley for most of the day. The severe threat will continue into Sunday as another system develops across the southern and central High Plains. A severe threat could develop from Oklahoma and Texas Sunday afternoon, but a lack of moisture is creating uncertainty regarding the magnitude of any severe threat.
