Areas affected...Parts of central and southeastern iowa
Concerning...Tornado Watch 27...
Valid 052333Z - 060130Z
The severe weather threat for Tornado Watch 27 continues.
SUMMARY...The tornado threat will be focused in parts of central and
southeast Iowa this evening. This threat may extend beyond the WW 27
and an additional downstream tornado watch will likely be considered
DISCUSSION...A strong supercell continues to move through southern
suburbs of Des Moines. This storm has had consistent rotational
velocities in the 55-70 kt range over the past hour. Other discrete
storms are moving out of north-central Missouri into south-central
Iowa. At least one tornado was reported in Wayne County, IA, with
this activity. These storms are moving into a similar environment
and will continue to pose a threat for tornadoes over the next 1-2
hours. To the west of these discrete storms, a more broken line of
convection has developed along the cold front. This activity will
pose greater threats for large hail and damaging winds than
Farther to the north and east, earlier cloud cover and precipitation
has limited destabilization. For parts of eastern Iowa and perhaps
far northeastern Missouri, an additional downstream tornado watch
will need to be considered this evening.
