Forecast: A potent area of upper ascent will move through today across the Las Vegas Metro zones, with a couple of rounds likely. Instability has been noted with over 500 j/kg at the moment in the mid-levels and a forecast over 1000 j/kg likely.
This would be enough to warrant storms coming out of the northwest into the Metro Las Vegas areas. Mid-level shear and steep lapse-rates present support the chance that the hail out there could reach over an inch in diameter.
Along with that, soundings show a classic inverted-V profile which promotes strong sinking for damaging winds with the storms.
Low-level moisture is not abundant but there is some low-level shear for funnels to be sighted from this system through the evening.
Expecting a full cease-fire from mother nature after the 10-11pm hour.
