Areas affected...Central into northeast Iowa
Concerning...Tornado Watch 378...
Valid 142247Z - 150045Z
The severe weather threat for Tornado Watch 378 continues.
SUMMARY...The potential for tornadoes will be focused in northeast
Iowa and potential parts of east-central Iowa. Farther west, veered
surface flow will limit tornado potential, though damaging winds and
perhaps isolated hail remain a possibility.
DISCUSSION...The remaining area of greatest concern for a continued
tornado threat exists in northeastern Iowa. A confirmed tornado was
located in Bremer County east of Waverly. This storm has remained
discrete and will likely be the focus for tornadic potential over
the next hour or two. To its southwest, another cluster of
supercells has recently grown upscale. While the storm mode would
indicate a lower tornado threat, temperatures downstream of these
storms have continued to warm into the upper 70s to low 80s F.
Surface winds remain backed and will continue to support enhanced
low-level SRH and potential for tornadoes.
To the west of I-35, surface winds have veered considerably and are
now west to west-southwesterly. Though storms have developed along
the cold front, these storms are more of a damaging wind gusts and
perhaps isolated large hail threat. The tornado threat in these
areas is relatively lower.
