discussion...

this morning's surface analysis indicates a 1028 hpa high pressure
area extending from the ohio river valley southwestward into south
central texas. The combination of light winds, clear skies, and
low dewpoints have allowed radiational cooling to occur through
the overnight hours resulting in temperatures ranging from the mid
50s near the coast to the upper 40s low 50s across interior se
texas and SW louisiana. The 00z klch sounding sampled pwat of
0.40" over the region and dry conditions are expected today thanks
to the lack of deep layer moisture and upper level subsidence.

Diurnal insolation should allow temperatures to climb into the
upper 70s which is slightly below normal for mid october.

The dry conditions are expected to continue through the week as an
upper level ridge builds along the east coast. Temperatures and
dewpoints are expected to gradually increase as the surface high
pressure shifts east of the area and allow for weak return flow to
develop. A 500 hpa trough is then forecast to progress across the
eastern two thirds of the CONUS through the weekend into early
next week. Model guidance over the past 24 hours has been trending
toward a more progressive pattern. Pwat values are expected to
increase to 1.5"+ on Saturday as low level flow becomes
southeasterly. A few pop up showers and thunderstorms could
develop as a result of this increasing deep layer moisture on
Saturday. The 00z gfs ECMWF are indicating the potential for deep
convection to develop along a surface cold front extending across
the southern plains Saturday afternoon and progress southeast
during the overnight hours and passing through the CWA on Sunday.

Drier and cooler conditions are expected to return by Tuesday as
high pressure ushers in another continental air mass into the
region.

Marine...

northeasterly flow will continue gradually decrease through this
morning as high pressure builds over the region. Sustained winds
are expected to generally below 20 knots after 7 am this morning.

However, they will still be around 15 to 20 knots with higher
gusts into early this afternoon. Therefore, the small craft
advisory will be allowed to expire this morning with exercise
caution wording added into the forecast through this afternoon.

The area of high pressure currently over the area will shift
eastward starting on Wednesday resulting in moderate easterly flow
through the end of the week. An approaching upper level trough
will result in onshore flow and the chances for showers and
thunderstorms increasing this weekend.

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.
