Discussion... 
the weak cold front was far enough south at 930 PM that only 
isolated showers were located over the Gulf waters offshore of 
Matagorda Bay. The surface high pressure located over the la/Arkansas 
border will continue to ridge into southeast Texas tonight. 


Tweaked the overnight low temperatures and humidity grids.

00z taf discussion in aviation section... 


Aviation... 
surface analysis has weak high pressure over miss River Valley. This 
will still allow for east winds which will decouple overnight. Ceilings 
should be VFR and with a slightly drier boundary layer...do not 
anticipate any mifg. East winds should increase again tomorrow to 
8-10kts with scattered high clouds.

Previous discussion... /issued 306 PM CDT Monday Oct 20 2014/ 


Discussion... 
shortwave ridging continues to dominate sensible weather for the 
region this week. Scattered showers with an isolated thunderstorm 
or two has developed offshore today in the presence of a weak /18z 
GOES sounder estimating 45 to 50 knots winds/ upper-level jet 
streak. Kept low rain chances in the forecast over the coastal 
waters through Tuesday before this feature departs ahead of a clipper 
system speeding across the Great Lakes. Otherwise... expect the 
dry pattern to continue over land with little change in day-to-day 
temperatures for the remainder of the work week and afternoon 
highs topping out in the 80s. 


Afternoon water vapor imagery shows a closed low over northern 
Mexico continuing to weaken as it drifts closer to the ridge over 
Texas...with another trough approaching the Pacific northwest. 
Models have come into better agreement regarding the evolution of 
this trough...with the European model (ecmwf) now resembling the GFS in terms of a 
faster...more progressive track and little in terms of rain 
chances for southeast Texas. As of right now...all this system looks 
to bring is an increase in cloud cover as it passes late 
Wednesday/ early Thursday. As this system crosses the Southern 
Plains...the ridge will build back in and keep temperatures above 
seasonal normals this weekend. There/S some uncertainty on when 
the ridge will build directly over southeast Texas and which 
day...Saturday or Sunday...will be warmer. For now... will side 
with Sunday based on 850 mb temperatures. 


The biggest forecasting concern this week centers around marine 
impacts from a disturbance in the Bay of Campeche. While this 
system is anticipated to drift off to the northeast towards 
Florida... east/northeasterly winds associated with this 
disturbance will produce elevated tide levels and increase the 
potential for strong rip currents. Please see the marine 
discussion below for more details. 


14 


Marine... 
a tightening pressure gradient (high pressure to the north and 
developing low pressure in/around the Bay of Campeche area) is 
expected to bring strengthening winds and increasing seas to the 
area. Caution flags will probably be needed beginning either 
tonight or Tuesday...and advisories are possible. There could 
also be elevated tide levels along with a threat for rip currents. 
Decreasing winds and seas are anticipated return to the area 
toward the end of the week. 42
