..no severe thunderstorm areas forecast...
thunderstorms will be possible across the Southern Plains and
southern New Mexico Friday...however severe storms are not expected.
A blocking pattern will result in little change to the large-scale
flow aloft on Friday with an upper-level low remaining over the
Great Basin and ridging aloft over the Gulf of Mexico/southeast U.S.
Stronger flow aloft will remain from the southern rockies east to
the southern/Central Plains. A strong cold front will continue
moving south and extend from the southern Great Lakes southwest into
central/southwest Texas by Friday evening.
Latest guidance remains in agreement in developing generally weak
instability in the vicinity of the cold front over central Texas
Friday afternoon...where widespread cloudiness should limit diurnal
heating despite middle-upper 60s surface dew points. In addition...this
area will be generally south of the more favorable deep-layer shear.
A few thunderstorms are expected near the front...however the severe
threat appears low.
Behind the front...precipitation will be widespread from the
southern rockies east across the Southern Plains and middle-Mississippi
Valley...and an isolated lightning strike is possible across
Texas/southern Oklahoma in the presence of weak elevated
