Areas affected...primarily southwest Missouri into northwest
Arkansas

Concerning...Severe Thunderstorm Watch 575...

Valid 310328Z - 310530Z

The severe weather threat for Severe Thunderstorm Watch 575
continues.

SUMMARY...A severe MCS continues to move south/southeast across
southwest Missouri and far southeast Kansas, with severe winds
measured. An additional watch will be considered downstream into
northwest Arkansas should current trends persist.

DISCUSSION...A small but impressive MCS continues to produce severe
gusts across much of the length of the line, with the most intense
portions generally west of the longitude of Springfield MO thus far.
Objective analysis shows some decrease in instability in that area
and extending to the east. However, a plume of higher PWAT does
exist per 00Z LZK sounding and GPS water vapor sensors with values
of 1.80-2.00" vs the 1.60" in the 00Z SGF sounding. Therefore, given
the organization of this MCS, it is possible that the severe risk
persists at least within a narrow corridor extending south/southeast
into parts of AR.
