(IowaStormCenter.com) — Severe thunderstorm and tornado threat increasing this afternoon through the evening over central and southern Iowa.
The main impulse of thunderstorms will build into western Iowa early this afternoon and gradually move east with additional development anticipated later in the afternoon.
The focus will be along the southern extent of this line where deep moisture and low-level shear will coincide along the frontal zone. This will support a tornado risk over southwest/central Iowa around 4-5pm extending through the evening.
Additional threats include hail, damaging winds and heavy rainfall. The severe threat will diminish before midnight tonight.
