Areas affected...Parts of southern Arizona

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

Valid 300119Z - 300215Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated severe wind gusts are possible this evening
across southern Arizona.

DISCUSSION...A few storms have formed across the higher terrain
across southern Arizona this evening. SPC mesoanalysis shows a
mostly capped airmass across most of the region, suggesting that
storms may struggle to maintain intensity once they move off of the
terrain. More organized storms remain mostly in Mexico where
stronger instability and better easterly shear is present. Both
shear and instability are more marginal north of the border and
thus, the severe wind threat should remain marginal/isolated.
Therefore, no severe thunderstorm watch is anticipated this evening.
