....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not expected on Tuesday.

....Synopsis and Discussion...
A shortwave trough is expected to extend from southern British
Columbia to off the central CA coast early Tuesday morning. A belt
of enhanced, largely zonal westerly flow is anticipated east of this
system, extending from the Great Basin through the OH Valley and
Northeast. The shortwave is forecast to make gradual eastward
progress throughout the day, likely extending from eastern MT across
the Great Basin and into southern CA by early Wednesday. Modest
upper ridging will build over the eastern CONUS downstream of this
system.

At the surface, lee troughing is anticipated across the High Plains,
with eventual cyclogenesis likely over the central High Plains
Tuesday evening. Resulting surface low is then expected to progress
eastward across KS. A broad warm sector, characterized by dewpoints
in the low to mid 60s, will exist from south TX into MO ahead of
this low. Warm-air advection will persist across this warm sector
throughout the day, with some low-level convergence possible along
the warm front as well. However, mid-level temperatures are expected
to remain warm, resulting in substantial convective inhibition and
prohibiting thunderstorm development. Dry and stable conditions are
expected elsewhere across the CONUS, with no thunderstorms expected
during the period.
