Area Forecast Discussion
National Weather Service Corpus Christi TX
509 AM CDT SAT MAY 28 2016

.SHORT TERM (Today through Sunday)...Concur with the GFS
deterministic with regard to the development of an upper ridge
over the region during the period. NAM deterministic predicts
moisture/instability sufficient for diurnal convection Today and
Sunday. Forecasting max heat index values generally below 105F
Today and Sunday.

&&

.SHORT TERM MARINE AND COASTAL...Will reissue the SCA for today
considering current observations and owing to expectation of
vertical mixing of greater momentum from aloft (CRP VAD wind
profile data) and increasing thermal gradient during the afternoon
which will also contribute to SCA over the SRN bays/nearshore
waters. Anticipate conditions consistent with a high risk for rip
currents Today.

&&

.LONG TERM (Sunday Night through Friday)...Southwest flow
at H5 continues with broad ridging sneaking in from the south early
in the extended. Capping remains over the region with H85
temperatures varying between 18C-20C which should limit convective
activity. But with pwats of 1.4-1.7 inches in place and embedded
impulses in the SW flow aloft, isolated showers and thunderstorms
remain possible, especially across the western Brush Country through
Monday night. During this time, H5 Low over southern California will
begin to move into the Desert Southwest, reaching the Four Corners
region Tuesday. This Low becomes absorbed in the main upper trough,
elongating the trough into Texas. The associated weak surface
frontal boundary should add more focus heading into the latter half
of the work week, with increased rain chances Wednesday and
Thursday, with best chances Thursday as the boundary sinks into S
TX. Models then dry things out by Friday. Overall, temperatures
remain persistent, with highs in the mid to upper 80s across the
Coastal Plains, to mid 90s across the Brush Country, with the
exception of mid 80s area-wide Friday behind the frontal boundary.
