transition to predominate MVFR ceilings light to moderate onshore
flow overnight early Monday morning.VFR conditions and breezy
onshore flow expected by early Monday afternoon.

Prev discussion... Issued 402 pm cdt Sun may 26 2019
short term (tonight through Monday night)...

warm and breezy conditions will persist through the short term
with mid level ridge across the northern gulf and surface low
pressure across the high plains. Sufficient moisture and steep
enough low level lapse rates may contribute to isolated streamer
showers across the coastal region late tonight through Monday
morning. By memorial day afternoon, dry conditions should be in
place with temperatures reaching into the mid to upper 80s along
the coast, to mid to upper 90s across the brush country. Mild
nights in the 70s are expected tonight and Monday night.

For those with interests along the coast, continue to expect a
high risk for dangerous rip currents through memorial day.

Long term (Tuesday through Saturday)...

extended period begins with onshore flow bringing chances for
streamer showers to the middle texas coast and victoria crossroads.

Spotty coverage means most locations will stay dry. Synoptic pattern
shifts subtly for midweek as flow becomes more zonal, allowing upper
level disturbances to push deeper into texas. Rain chances increase
mainly over the northern and northeastern counties through Friday,
when ridging builds back into the region to suppress rain chances
into the weekend.

Temperatures will remain near to slightly above normal through the
week, with high humidities and afternoon breezes.

Marine...

a moderate onshore flow will persist through Monday. Winds will
strengthen to moderate to occasionally strong onshore flow Monday
night through Wednesday, when small craft advisories may be
needed. Flow becomes more zonal midweek, which may relax the
gradient down to light to moderate levels. Onshore flow then
increases to moderate for the weekend.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
