...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe storms are not expected on Thursday.

...Synopsis...

Upper ridging will persist over the Plains on Thursday. A weak
shortwave impulse will move through the top of the ridge toward the
Upper Great Lakes while another shortwave trough approaches the
northern Plains by the end of the period. A large upper cyclone is
forecast to remain offshore the Pacific Northwest coast while
Hurricane Priscilla parallels the Baja coast.

Strong surface high pressure over the Great Lakes will result in a
mostly dry and stable airmass across the Midwest. While some modest
moisture will return northward across the Plains on the western
periphery of the surface high and ahead of the northern Plains upper
shortwave trough, boundary layer moisture will remain meager across
the Plains, precluding thunderstorm activity. Isolated storms are
possible across parts of the Southeast where lingering moisture will
be in place behind a prior cold frontal passage, but severe storms
are not expected. Additional storms are possible across parts of the
Southwest where low-level south/southeasterly flow will transport
modest boundary layer moisture across the region. Poor lapse rates
will limit instability to less than 500 J/kg MLCAPE and severe
storms are unlikely.
