...no severe thunderstorm areas forecast...
...summary...
severe thunderstorm potential appears low on thursday. however,
locally gusty winds could occur with thunderstorms across the
central high plains.
...discussion...
in the mean, an amplified upper ridge will persist across he west,
with the subtropical high over tx shifting west toward the four
corners vicinity through the period. an upper shortwave trough
embedded within the eastern periphery of the upper ridge will
migrate southeast from the central rockies to the mid/lower mo
valley through early friday morning.
southerly low-level flow across the plains will result in a belt of
modest boundary-layer moisture across the central high plains. steep
midlevel lapse rates will foster weak instability across parts of
wy/co into western ks. scattered thunderstorms will develop during
the afternoon and spread east/southeast across the central high
plains. a deeply mixed boundary layer will support isolated strong
outflow gusts. however, weak vertical shear and limited instability
will preclude severe probabilities at this time.
