NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
622 PM CDT Monday Sep 22 2014 


Discussion... 
updated aviation discussion. 


&& 


Aviation... 
scattered showers now over SW portion of the forecast area...and 
only affecting lbx and gls at this point. Did have thunderstorm 
over east end of Galveston Island an hour or so ago that pushed an 
outlfow through gls of 33 knots. Outflows have made it tough for 
showers to maintain themselves and these should be clear of gls 
and lbx within the next hour or so. After that...with somewhat 
drier air filtering in...looking at VFR conditions with generally 
northeast winds and no more than some patchy cirrus as we go 
through the overnight and Tuesday. 46 


&& 


Previous discussion... /issued 338 PM CDT Monday Sep 22 2014/ 


Discussion... 
scattered rain showers/thunderstorms beginning to fire along & south of frontal boundary 
currently backdooring into the region. May see some slight 
storm enhancement as they near the coast later in the day where a 
weak sea & baybreeze is situated. Expect most activity to 
diminish early to middle evening as a much drier airmass filters in. 


Being on the SW periphery of a large surface high pressure system expect 
several days of pleasant weather across the region with persistent low level 
east-northeast flow in place. Will probably see some cloudiness return during 
the 2nd half of the workweek as some low level moisture advects in 
from the east and a middle level weakness to our west draws in from 
cloudiness from the SW. Deeper moisture offshore will lead to 
rain chances there...especially late Thursday-Sat as west/ coastal trough in the 
vicinity. GFS is much wetter inland this weekend (which is something 
to keep an eye on forecast-wise) but still prefer the drier European model (ecmwf) 
which shifts precipitation/moisture east along west/ the weakness & coastal 
trough progression. 47 


Marine... 
an decent easterly fetch will set up late this week. The combination 
of easterly winds and especially high tides associated with the new 
moon could lead to minor coastal flooding around the times of high 
tide by Thursday or so. Swells over the Gulf may also lead to 
caution conditions by Thursday as well. 40
