Area Forecast Discussion
National Weather Service Corpus Christi TX
640 PM CDT Sun Jun 4 2017

.DISCUSSION...

Numerous boundaries across the coastal bend and brush country have
led to scattered convection, some strong to severe. Expect this
convection to gradually weaken over the next couple of hours as
usually occurs with diurnal convection. With very high PWAT air,
most of these storms will produce heavy downpours. Outside of
thunderstorms, expect mainly VFR conditions, though brief MVFR
conditions will be possible. LRD terminal expected to remain dry
with VFR conditions through the period.

&&

.AVIATION...
Convection continues early in the period for all eastern sites.
Expect a dissipating of convection into the late evening and a
lull for a few hours into the night. Thunderstorm chances back
into the forecast Monday morning and afternoon. A mix of

.PREVIOUS DISCUSSION... /Issued 418 PM CDT Sun Jun 4 2017/

SHORT TERM (Tonight through Monday Night)...

You get a boundary, everyone gets a boundary. Boundaries galore
across the region as storms develop along them from the northeast
zones, to offshore and in between. Basically we are targeting the
eastern half of the CWA/MSA for tonight where the best moisture axis
and continued outflow boundary influences will remain. A majority of
the convection is sub-severe and expected to remain that way since
there is very little in the way of shear for more organization and
better updraft/downdraft separation. Some small hail, heavier rain,
and gusts to 50 mph are possible but being pulse convection, they
won't last long.

Another vort max pushes into the region from the northwest as the
mid-level low/trough moves by to our north. Again we favor the
eastern half of the region as PWATs continue to climb towards 2.0",
well above average, with boundaries hanging around. Activity should
begin to wane by late evening tomorrow with most activity over the
open gulf waters.

LONG TERM (Tuesday through Saturday)...

Rain chances will be winding down as the extended period opens as a
longwave pattern change gets underway. Just a small chance for
leftover showers on Tuesday as an upper trough clears the area, then
drier air begins to push into the region. One more weak disturbance
moves through on Wednesday, but by then we should be too dry for
rain.

After that ridging builds into South Texas, bringing dry weather and
gradually warming temperatures the rest of the week.
