Valid 301200Z - 311200Z

...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorm potential appears low on Friday.

...Synopsis...
As upper-level ridging increases within the northern Plains, a
shortwave trough in the Southwest will evolve into a nebulous trough
within the southern/central Plains. Stronger mid-level flow will
arrive within the lower Colorado Valley vicinity towards late
afternoon into the evening as a shortwave trough approaches the Baja
Peninsula.

A broad swath of convection/precipitation is expected in association
with the shortwave trough and warm-advection within the Missouri
Valley vicinity. Poor lapse rates and limited buoyancy should limit
the intensity of this activity. Additional storms are possible
during the mid/late afternoon in the lower Colorado Valley into
parts of southern/central Arizona. Cooler temperatures aloft will
support modest buoyancy (500 to around 1000 J/kg MLCAPE). While a
strong storm or two could produce small hail, shear will remain
limited during the afternoon and should keep severe risk low.
