....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not expected on Friday.

....Synopsis...
A somewhat progressive upper pattern is anticipated on Friday as a
pair of shortwave troughs, one initially extending from the Upper OH
Valley into the Mid-Atlantic and the other from the eastern Great
Basin into AZ, both move eastward across the CONUS. The lead wave is
forecast to move off the Northeast coast by Friday evening while the
wave in its wake moves into the central and southern Plains.

Some moisture return is expected ahead of the Plains shortwave, with
60s dewpoints likely in place across much of southern, central, and
east TX by Saturday morning. However, warm temperatures aloft should
limit thunderstorm development within this return flow. Dry and
stable conditions will preclude thunderstorm development elsewhere
east of the Rockies.

The upper pattern over the western CONUS should begin amplifying
Friday evening into Saturday morning as another strong shortwave
trough approaching the West Coast. Strong ascent and a well-defined
frontal band will approach the northern CA coast Saturday morning,
but any deeper convective cores capable of lightning should remain
offshore.
