Valid 141200Z - 151200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not forecast Tuesday.
...Discussion...
Eastern US trough is forecast to move off the Atlantic Coast during
the latter half of the period as the associated upper low deepens
just east off the MA Coast. As a result, strong surface anticyclone
will settle into the MS/OH Valley region and this feature will
dominate much of the country east of the Rockies. Offshore flow will
prove detrimental for meaningful instability and the prospect for
severe thunderstorms is very low.
Weak convection may develop ahead of the front over extreme south
FL, portions of TX ahead of a weak short-wave trough, and across
portions of CA in response to the next in a series of short waves.
In each area, limited buoyancy will result in just isolated
thunderstorms where convection is able to deepen enough for
lightning discharge.
