Areas affected...Central into northeast MT
Concerning...Severe Thunderstorm Watch 416...
Valid 150446Z - 150615Z
The severe weather threat for Severe Thunderstorm Watch 416
continues.
SUMMARY...Strong to locally severe storms may continue into the late
night.
DISCUSSION...Scattered storms are ongoing late this evening across
parts of central MT. While intensities have decreased somewhat from
the earlier severe hail producing storms, a storm has recently
intensified in Wheatland County. MUCAPE of 500-1000 J/kg and
relatively strong effective shear (40-50 kt) will continue to
support occasionally organized storms late tonight, with a threat of
isolated hail and strong to severe gusts.
Guidance varies regarding the magnitude of the severe threat into
the overnight, though persistent convection within a sufficiently
unstable and sheared environment could support an isolated threat
eventually spreading into parts of northeast MT with time.
