Areas affected...Parts of central and eastern Iowa
Concerning...Tornado Watch 370...
Valid 242039Z - 242245Z
The severe weather threat for Tornado Watch 370 continues.
SUMMARY...The threat for large hail, tornadoes, and damaging winds
will continue this afternoon. The main risk will be in parts of
southeastern Iowa in the next 1-2 hours.
DISCUSSION...Winds in southwestern Iowa have veered to
southwesterly. This trend continues to expand into parts of central
Iowa as well. Where this has occurred, the tornado threat has
decreased. Convection continues into northeast Iowa this afternoon.
However, anvil debris and only partially modified outflow have kept
buoyancy less than in southern/southeastern Iowa. Large hail and a
brief tornado remain possible with the strongest storms.
The primary area of tornado risk for the next 1-2 hours will likely
exist with storms in south-central/southeastern Iowa. Here,
buoyancy, storm mode, and low-level shear remain favorable.
As storms progress farther into eastern Iowa, they will encounter
decreasing moisture and increasing temperatures. While the tornado
threat will decrease with eastward extent, large hail and damaging
winds could still occur.
