430 am cst Wed dec 13 2017

Near term now through Wednesday night Surface high pressure
builds over the eastern gulf through the near term, beneath a
zonal flow pattern aloft. Local winds shift to more southwesterly
and we see a slight bump in moisture as a result. Otherwise, the
near term remains dry beneath mostly clear skies. Southwest flow
and bump in moisture means low temps stay above freezing for most
tonight, with the exception being areas north of highway 84 where
temps could dip to around freezing. 49

Short term Thursday through Friday night Zonal flow aloft
will persist over the region downstream of a developing upper low
pressure area over northwest mexico. Light southwesterly to
westerly winds on Thursday afternoon will precede a weak cold
front approaching from the north. This front will move south
across the area Thursday night, bringing a northerly flow back
into the region on Friday. A few showers may occur along the coast
Friday morning with the passage of the front. Otherwise, rain-
free conditions will persist through the short term. 22

Long term Saturday through Tuesday The upper closed low
pressure area over northwest mexico will lift northeast over
western texas, and evolve into an open wave as it merges with a
strong upper level shortwave moving from west to east from the
great plains to the east coast early next week. Meanwhile, a
1025mb surface high pressure area over the southeast states
Saturday morning will move northeast as a developing surface low
pressure area across the western gulf of mexico lifts northeast
across the southern mississippi river region. Flow will follow
late Saturday and Sunday as the center of high pressure moves east
of the area.

There is better timing with this system between the ECMWF and gfs
this run, with a 40 to 60 knot low level jet setting up over the
forecast area on Sunday. A 120 to 140 upper level jet is still
expected to develop over the eastern conus, with the forecast area
residing in the favorable right entrance region on Sunday.

Adequate wind shear will certainly be in place early next week
with this system, along with upper level diffluence and mid level
lift, instability in the low to mid levels is still undefined.

The dry period will persist through midnight Saturday night,
followed rain increasing from west to east after midnight. A 90
percent chance of precipitation is forecast for Sunday. Given
the strong dynamics advertised by the models, increased to a
chance of thunderstorms embedded in the definite rain showers.

This system may bring a round of strong to marginal severe
weather with damaging winds and possible tornadoes being the main
threats if higher MLCAPE values are realized. 22

Marine Offshore flow weakens today before becoming
southwesterly and increasing back to exercise caution levels
tonight into early Thursday. A lighter west flow then sets up
Thursday before another front moves through and moderate offshore
flow develops Friday. Moderate to strong onshore flow returns by
Sunday ahead of yet another approaching front. Seas generally
around 2 to 4 feet through the end of the week, then building to 5
to 8 feet Sunday due to the onset of stronger onshore winds. 49

If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
