Our NWS is sure getting creative lately.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAKE CHARLES LA
147 PM CDT FRI JUN 18 2004
.SYNOPSIS...
A warm cirrus-level HIGH, which currently ridges southwest from
Georgia through the upper Texas coast, will begin its breakdown on
Saturday. A difluent southerly flow will subsequently evolve across
southwest Louisiana and southeast Texas. Meanwhile, further north
across the Ohio Valley, a cool surface HIGH will abruptly push a cold
front south. This sudden push of the cold front southward will send
gravity waves into southwest Louisiana.
The ongoing breakdown will continue into Sunday; permitting group
waves, emanating out of the Colorado Rockies, to rotate through
northern Louisiana. Meanwhile gravity waves will continue to
propagate southwest through southwest Louisiana.
.DISCUSSION...
A friendly environment will be in-place this weekend for convective
rains. Strong thunderstorms are possible; the normally short-lived
thunderstorms will be more organized; and thus last longer.
Otherwise, temperatures will be about seasonable.
&&
Yesterday it looked like the weekend will be dry. By the way, how would gravity waves affect precipitation?
