SHORT TERM (Today through Wednesday)...
The final vestiges of rain had already shifted well offshore
early this morning ahead of drier northerly winds and rising
ceilings. Stubborn post-frontal stratus will still make for a
dreary morning along the Coastal Bend, while our western counties
enjoy a bit more sun. The bigger picture today involves a compact
low peeling into the Ozarks while a belt of strong upper winds
lingers closer to home. Even as stratus breaks up this afternoon,
models show a stubborn layer of saturation around 700 mb that
should keep the eastern half of the CWA mostly cloudy and cooler
than points farther west. Breezy northerly winds will relax later
today as surface ridging draws closer while prepping the stage for
a chilly night under mostly clear skies. Light northerly winds
tonight will veer more easterly on Wednesday as the surface ridge
shifts into the Gulf, yet highs should still warm a solid 5 to 10
degrees over today as weak upper ridging unfolds with mostly sunny
skies for all areas.
LONG TERM (Wednesday Night through Monday)...
The long term period starts out with mid-level ridging over the
Great Plains with a developing low moving into the Desert Southwest.
Surface high pressure over eastern part of TX will promote onshore
flow across the Coastal Bend spreading moisture inland through early
Friday ahead of a cold front. Temperatures will continue to warm
each day and could see low to mid 80s by Friday. The aforementioned
mid-level low will skirt east across the Rockies before diving south
bringing our next front. FROPA is expected to occur Friday
morning/afternoon reaching the coast by the evening hours. Only
expecting some isolated showers in far eastern portions and the
Coastal Waters due to isentropic lift favoring these areas co-
located with above normal PWATs around 1.30". Colder air will
filter in behind the front knocking our temperatures back down
Saturday. Onshore flow quickly resumes after the front moves
offshore and the warming trend will resume with subsidence over a
broad area with a surface high in the Southeastern CONUS and a mid-
level high over Central Mexico. These conditions will lend to a
quiet end to the long term period.
MARINE...
Strong northerly flow this morning with Small Craft Advisory
conditions will taper to moderate levels from west to east this
morning and afternoon. North winds become weak to moderate tonight
as high pressure draws closer, before turning northeasterly and
easterly on Wednesday and remaining mostly weak. Weak to
moderate onshore flow continues Wednesday night through Friday
morning. Increasing moisture will contribute to a few showers by
Friday ahead of a cold front. Some sea fog could develop later
this week until dry offshore flow arrives Friday night behind the
front. Winds will become moderate to strong Saturday morning,
becoming more moderate as flow shifts to onshore by Sunday
evening.-- End Changed Discussion --
