more supportive for afternoon showers with some daytime heating.

Mid level ridging will weaken slightly today through mid week
allowing for some convection to get started each day. This is
mostly noted by the inversion level lifting and moistening to
about 10k ft. Most of this activity should be able to reach about
20k ft today which will be in the form of showers but there could be
a few cells that punch through to 35k ft or higher causing the
formation of a few ts. As always...these will be watched
Chances for rainfall will remain relatively stable through
After Wednesday...rainfall chances should rise to see a fairly
good area wide distribution as a cold front moves eastward out of
Tx. The long wave trough providing support will move through
slowly starting Thursday and should clear the area Saturday
Radar continues to show some showers around the area with most of
the activity west of all of our terminals. Lower ceilings are
possible in and around these showers, should they move into the
vicinity of one of the terminals. At this time, the expectation is
that the chances are not high for that to occur and therefore no
mention of rain are in the TAFs. Overall, mainly VFR conditions will
be the norm with MVFR conditions possible at times.
High pressure will continue to dominate the flow over the coastal
waters through the rest of the week with winds generally out of the
southeast at 10 to 15 knots through the weekend. Seas will be on the
order of two to three feet. With the center of the high developing
over the coastal waters Monday and Tuesday winds will decrease
and become light and variable with seas of 1 to 2 feet.
