..no severe thunderstorm areas forecast...
severe thunderstorms are not expected on Monday.
..synopsis and discussion...
Model guidance is in good agreement that the upper pattern will
become more progressive on Monday with the deep upper troughing
covering the eastern Continental U.S. Beginning to lose amplitude and shift
eastward. At the same time, western Continental U.S. Ridging will likely dampen
as it gradually moves eastward. A southern-stream shortwave trough
is expected to approach the Southern California coast late in the period.
Expansive high pressure will dominate the sensible weather across
the majority of the lower 48 states. The only exception is along the
Texas Gulf Coast, where are stalled front may interact with remnant
low-level moisture to support isolated thunderstorms. No severe
thunderstorms are anticipated.
