Areas affected...Portions of the northern and central Plains
Concerning...Severe Thunderstorm Watch 500...
Valid 100418Z - 100615Z
The severe weather threat for Severe Thunderstorm Watch 500
continues.
SUMMARY...Gusty winds will continue to be noted along the leading
edge of squall line.
DISCUSSION...Weak short-wave trough has topped the northern High
Plains ridge and is now turning southeast across the eastern
Dakotas. This feature appears to be partly responsible for a near
500 mi broken squall line that is propagating across the eastern
portions of the northern and central Plains. Isolated severe wind
gusts continue along the leading edge of this linear MCS, but much
of this convection is producing sub-severe gusts. This activity
should continue propagating through the remainder of ww500 with an
attendant risk for at least isolated severe, and a local extension
may be warranted.
