Discussion
The weather conditions will continue to be pleasant through the
weekend. A high pressure system, which has moved through our area
for the beginning of the week, will continue eastward through the
weekend. This high pressure system will cause the winds to be
northerly through Sunday into Monday. This northerly wind helps
add to the subsidence and lack of lift caused by upper level
convergence. So, through Sunday the atmosphere is expected to be
mostly stable with no showers.

As this high pressure system moves out of the area, the winds
will shift from having a northerly component to a southerly
component. This wind shift from the south will cause warm air
advection into the area, which in turn will enhance the moisture
and lift in the area. In addition, these winds from the south
will allow for some directional shear to be present in the
atmosphere as well. A low pressure system is expected to move into
the area at the beginning of the next week, mainly Monday and
Tuesday. The models show uncertainty in the amount of speed shear
present. Ultimately, the amount of speed shear will be dependent
upon the strength of the frontal system and the jet stream. There
is expected to be upper level divergence in the area Monday
morning, which will also enhance the amount of uplift in the area.

Mid-level winds leading up to and during the passage of this cold
front are northerly, which is indicative of cold air advection.

The presence of this cold air in the mid-levels will cause the
lapse rates to be higher, which raises the chance of a
thunderstorm or two occurring during the passage of this frontal
system. In summary, a wind shift from northerly to southerly will
allow for some uplift and shear in the area to begin building at
the end of this weekend. Ahead of the frontal system on Monday the
winds and lift are still expected to enhance the atmosphere to be
favorable for the development of some showers and a few
thunderstorms as the frontal system propagates through our area
Monday into Tuesday.

After the cold front passes Tuesday, the atmospheric pattern is
expected to be neutral, and the environment is expected to return
to the normal diurnal pattern into Wednesday of next week. Msw

Aviation
Very favorable terminal conditions will continue with clear skies
and excellent visibility expected through Friday. 22 td

Marine
High pressure will build into the central gulf coast region
through Friday before moving east across the atlantic coast over
the weekend. The pressure gradient will continue to support
northwest to west winds up in 10 to 15 knots to locally stronger
range at times through tonight and early Friday morning. A weak
pressure gradient should allow wind speeds to drop to around 10
knots or less across most waters by late Friday morning and
continuing through Sunday as they veer around to east then
southeast. Southerly winds mostly around 10 knots are expected on
Monday, then the next moderate strength cold front is expected to
push through the area Monday night. This will cause winds to shift
to west then northwest and north late Monday night through
Tuesday night with speeds up at least around 15 knots. 22 td
