Area Forecast Discussion

.SHORT TERM...
Deep tropical moisture over the western gulf will move into the
area from the southwest ahead of an upper level trough that has
sharpened from northeast to southwest into Texas. This moisture
will slowly move over the area today through Thursday. The
environment that will be advecting through the area will cause
convective temps to fall from 88F to around 80F while the deep
moisture will allow precip water values to rise into the 2+"
levels. This will make it very easy to produce sh/ts across the
area later today through Thursday. As this tropical air mass moves
to the northeast of the area, convective temps will rise. But as
the moisture remains in place, precip water values should remain
elevated enough to help in the production of sh/ts once again
Friday. By the weekend, precip water levels should fall back to
more normal levels only allowing for hit and miss coverage going
through the weekend into next week.

&&

.AVIATION...

Convection is expected to develop and expand in coverage mainly
after 17Z at nearly all terminals. Otherwise, VFR conditions are
expected outside convection where IFR to MVFR conditions are likely.
Downburst wind potential around 35 knots Wednesday.

&&

.MARINE...

Onshore flow has generally returned and will be in place through the
remainder of the forecast period. Winds will remain weak for most of
the forecast with a few periods of 10 to 15 knot winds being the
max. Seas will remain on the light side as well except near and any
thunderstorms that develop.
