LONG TERM [Thursday through Monday]...
As the extended period begins, the upper flow is forecast to be
largely zonal. However, a shortwave within this flow will be
pushing through Texas, with southwesterly flow overrunning the
stalled frontal boundary along the northern Gulf coast. Isentropic
lift is forecast to intensity along this boundary on Thursday,
allowing for a broad area of showers to push north into the
forecast area. At this time, it appears the instability will not
be sufficient for thunder, as the sfc boundary remain very close
to the coast.
By Friday, the shortwave will push off to the east. However, the
sfc front is expected to remain stationary or push just south of
the region. This may allow for a few showers even during the day
By Saturday, high pressure will nose down the eastern seaboard
and push the boundary farther south of the area. This should keep
the region dry through the weekend. With the zonal flow aloft and
no source of cold air, temperatures are expected to remain above
normal through the end of the week.
