Region 1
As an area of low pressure lifts northeastward over the Plains, an active weather day is expected from east Texas northeastward across Louisiana, Arkansas, and Missouri. As of this morning, showers and thunderstorms are ongoing from eastern Texas into Missouri. The activity over southeast Texas is expected to persist and move across the Houston Metro through early afternoon.

Further to the north and east, current activity will dissipate by midday, allowing more intense thunderstorms this afternoon. The highest tornado threat appears to be focused across Arkansas into southern Missouri. The highest threat for severe winds and hail will be from northern Louisiana northward into central Missouri. By late evening and the overnight hours, thunderstorms will organize into squall lines resulting in the threat for severe wind gusts spreading eastward toward the Mississippi River.

Another area of low pressure moving into the Plains will bring the potential for thunderstorms across portions of the Southern Plains on Saturday. Snow is also forecast for portions of the Northeast as an area of low pressure intensifies off the coast. As the area of low pressure over the Plains intensifies, excessive rainfall is possible across the northwestern Gulf Coast on Sunday.
