Areas affected...north-central Montana

Concerning...Severe Thunderstorm Watch 609...

Valid 070256Z - 070400Z

The severe weather threat for Severe Thunderstorm Watch 609
continues.

SUMMARY...Damaging wind threat continues in WW609.

DISCUSSION...A cluster of storms across northern Montana continues
eastward, with a trend toward more linear storm mode. This will
support increasing potential for strong to severe gusts. Radar from
Great Falls (KTFX) shows an increase in winds 45-55 mph around 1 kft
within the line northwest of Great Falls, with an increase in
lightning activity over the last 30 minutes. Though the downstream
environment is characterized as weakly unstable (MLCAPE around 250
J/kg), strong deep layer shear around 45-50 kts could continue to
support a few organized segments with potential for strong to severe
gusts.
