Areas affected...Southwest into southern/central MT vicinity

Concerning...Severe potential...Watch unlikely=20

Valid 051907Z - 052100Z

Probability of Watch Issuance...20 percent

SUMMARY...Thunderstorms will increase in coverage and intensity
through the afternoon while spreading from southwest Montana into
central portions of the state through evening. Isolated strong wind
gusts will be possible, though a watch is not expected.

DISCUSSION...Strong heating into the 80s amid steep midlevel lapse
rates is supporting weak destabilization early this afternoon across
the higher terrain of southwest MT and vicinity. Isolated
thunderstorms are developing over the higher terrain within 30-40 kt
effective shear magnitudes, and coverage should increase as storms
track toward the northeast. Fast-moving storms may pose a risk for
strong winds through the afternoon, particularly given large temperature-dewpoint spread and steepening low-level lapse rates.
However, instability will remain weak and limit greater organized
severe potential.
