NEAR TERM /Now Through Monday/...Ridging, both surface and aloft,
building over the forecast area tonight and Monday. This will result
in a continued rainfree pattern with clear skies and gradually
moderating temperatures and dew point temperatures. Surface winds
will remain light, mainly out of the east and southeast through
Monday. With the gradually increasing atmospheric moisture,
afternoon relative humidity will also be on the increase. Minimum
RH`s in the upper teens and lower 30s across the region this
afternoon will moderate to the low to mid 30s across most of the
region Monday afternoon. Temperatures will also be slowly increasing
across the region as well. Lows tonight ranging from the mid to
upper 40s across inland areas to the low to mid 50s along and south
of the I-10 corridor. Highs on Monday ranging from the mid to upper
70s near the coast to the lower 80s over most interior locations.

SHORT TERM /Monday night Through Wednesday night/...Surface high
pressure will move east of the area Monday night with the upper
ridge also slowly moving east. This will maintain dry conditions
with warming temps. Moisture levels will also slowly increase
through the period. Highs will be in the upper 70s and low 80s.

LONG TERM /Thursday Through Sunday/...Global models have come
into better agreement in a strong southern stream shortwave
closing off into an upper low across the southern plains with the
associated sfc low and trailing cold front moving east. This will
bring increasing rain chances Thursday into Thursday night as the
cold front moves through. Rain showers linger into Friday as the
upper low moves across the Gulf coast. High temps remain in the
upper 70s and low 80s through the period. /13

MARINE...A light and somewhat variable wind flow will persist across
the marine area tonight through late Wednesday as a weak surface
ridge of high pressure remains centered over the northeast Gulf. A
slight onshore component is expected each day and a slight offshore
component during the overnight hours. On Thursday, an increasing
southeast to south flow, along with building seas, is expected as a
cold front approaches from the west. The front moves east across the
coastal waters on Friday, followed by a moderate northerly wind
flow. 12/DS
