Areas affected...north central through west central Minnesota

Concerning...Severe Thunderstorm Watch 537...

Valid 040204Z - 040400Z

The severe weather threat for Severe Thunderstorm Watch 537
continues.

SUMMARY...Stronger storms, mainly those initially forming along the
eastward advancing cold front, may continue to briefly pose a risk
for severe weather into the 10 PM-midnight time frame.

DISCUSSION...The surface frontal zone now appears to be in the
process of advancing eastward, with 2-4 mb 2-hourly surface pressure
rises recorded in 01Z observations west of Bemidji MN through
Wahpeton ND and north through west of Watertown SD. This appears to
be occurring in the wake of a developing surface frontal wave which
likely will overspread the International Falls area (where 2 hourly
falls on the order of 2 mb are evident near and to its southwest)
within the next few hours.

Thunderstorm activity does continue to increase along and to the
cool side of the front, with initial stronger storms developing
along the front likely to continue to be quickly undercut. But
these could still briefly pose a risk for damaging wind gusts and
perhaps a brief tornado, in addition to large hail, into the 03-05Z
time frame.
