NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1127 PM CDT Sat Oct 25 2014 


Discussion... 
updated aviation section. 


&& 


Aviation... 
mainly VFR conditions to continue through taf forecast period with 
little or no cloud cover or visibility restriction. Only exception 
would be some areas of shallow ground fog...especially at the more 
prone sites of lbx and cxo...as was advertised in the previous taf 
issuance. Will also continue a brief period of MVFR visibilities at cll 
around sunrise...although confidence not so high that will occur. 
Elsewhere fog not expected...with VFR conditions throughout. 46 


&& 


Previous discussion... /issued 950 PM CDT Sat Oct 25 2014/ 


Discussion... 
see no reason to make any changes to the forecast this evening. Surface 
high pressure over the area tonight will edge off to the east tomorrow. 
As a result...winds will come around to south and southeast during the 
day and strengthen resulting gradually increasing dew points and humidities 
especially into tomorrow night and Monday. Tonight's low temperatures 
(upper 50s to around 60 inland and middle to upper 60s at the coast) should 
be the coolest temperatures the area sees until Thursday night when 
some cooler and drier air begins filtering into the area behind our 
next cold front. 42 


Climate... 
with under a week left in the month (thru the 25th)... 


-cll's October rainfall total of 1.81 inches is 2.23 inches below normal. 
-Cll's rainfall total for 2014 of 31.15 inches is 1.59 inches below 
normal. 


-Iah's October rainfall total of 2.95 inches is 1.68 inches below normal. 
-Iah's rainfall total for 2014 of 34.72 inches is 5.90 inches below 
normal. 


-Hou's October rainfall total of 2.56 inches is 2.28 inches below normal. 
-Hou's rainfall total for 2014 of 32.08 inches is 13.07 inches below 
normal. 


-Gls's October rainfall total of 1.75 inches is 2.95 inches below normal. 
-Gls's rainfall total for 2014 of 24.11 inches is 17.80 inches below 
normal.

Discussion... 
updated aviation discussion. 


Aviation... 
made very few changes. Little or no cloud cover...light winds and 
little or no visibility restriction through taf forecast period. 
Only exception...still capturing possibility of some ground fog 
at the usual spots...mainly lbx and cxo. Some light fog also 
mentioned at cll for a few hours. Will reevaluate this at the 06z 
issuance. 46 


Previous discussion... /issued 231 PM CDT Sat Oct 25 2014/ 


Discussion... 


Clear skies across southeast Texas today with temperatures in the 80s inland and 
around 80 along the coast. Light southerly winds tonight will 
allow low-level moisture levels to gradually increase and min 
temperatures will be a little warmer tonight as a result. Will also 
likely see some patchy ground fog as well. 


The warmer min temperature trend will continue through middle-week as low- 
level moisture continues to increase. The next chance of rain will 
begin Tuesday afternoon across primarily northern portions of the 
area. The best chance of showers/thunderstorms will be on Wednesday as a cold 
front moves into the area. Will see drying behind the boundary 
from the NE to the SW during the Wednesday night through Thursday after 
period. Although there are still some differences between the 
European model (ecmwf)/GFS concerning the middle/upper pattern at the end of the 
week...this will only affect how strong the secondary push of 
colder air is at the end of the forecast period. Should at least see a 
5-10 degree cool down on Friday...possibly significantly cooler 
air will be in place next weekend...especially if the more 
amplified European model (ecmwf) solution verifies. 33 


Marine... 
onshore flow should resume later tonight and Sunday as 
surface high pressure moves east of the region. Gradient will temporarily 
tighten early in the week and corresponding winds/seas will increase 
into early next week (maybe borderline caution criteria sun & Monday 
nights). The gradient loosens & wins/seas then subside into midweek 
as a weak frontal boundary sags into southeast Texas. Front will probably hang 
up near the coast or just inland - then eventually get a secondary 
push offshore Thursday night or Friday. Moderate to strong offshore 
flow in its wake will probably require advsy flags into the 1st part 
of the weekend. 47
