NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1022 am CDT Tuesday Sep 1 2015 


Discussion... 
locally heavy rainfall has been falling so far this morning generally 
to the south of Highway 59 and especially across portions of Galveston 
and Brazoria counties (between the South Houston area and Galveston 
island) where an estimated 1 to 3 inches has occurred. At 10 am...a 
large cluster of storms from the Richmond-Rosenberg area to Galveston 
Island lines up well with the coldest cloud tops on infrared satellite images... 
and this is where locally heavy rainfall continues to fall. Recent high 
resolution models keep this activity going on for a couple more hours... 
then spread outflows with more isolated shower and thunderstorm coverage 
northward across the rest of our area as the afternoon progresses. Not 
real confident on how much longer these storms will last or how far 
inland they will get as the day progresses...so will leave the forecast 
as is for now (highest rain chances near the coast and lowest chances 
up north) and do some updates as needed. 42 
&& 


Previous discussion... 


Discussion... 
while we are seeing some precipitation development near the coast overnight 
this activity has not lasted too long. Of greater concern looks to 
be the more organized activity down the Texas coast...which is expect- 
ed to head this way today. Locally heavy rainfall possible as this 
large area of precipitation moves across southeast Texas...with the best chances near 
the coast (where deeper moisture/best lift will be located). Not a 
lot of change from earlier thinking of average rainfall totals of 1/2" 
to 1" north of I-10... and 2"-4" south of the Interstate. 


This pattern (in some form) will likely be repeated tomorrow given 
the nearly stationary upper low/trough over south Texas. Timing of shortwave 
energy associated with this system looks to be the main issue look- 
ing forward. European model (ecmwf)/NAM remain the favored models as they appear to 
be initializing/verifying best. 41 


Marine... 
small band of showers/thunderstorms moved through Galveston Bay 
earlier this morning but short wave can be seen on water vapor imagery 
nearing crp at 09z and widespread showers and thunderstorms have 
formed over the lower and middle Texas coastal waters. This short wave 
should rotate east and northeast and help to enhance development 
later this morning over the Upper Texas coastal waters. Wind 
profile is relaxing over the coastal waters and may get a window 
of a few hours with an elevated waterspout threat after 9 am 
before development inland gets going. Lull in storms should occur 
by 3 PM over the Gulf waters. Repeat expected Wednesday morning 
then as upper shear axis/low moves east the coverage should slowly 
decrease and return to the more normal diurnal pattern. Winds 
remain at 15 knots or less through the period with plenty of 5-10 
knot periods thrown in there with the departure of the upper 
trough to the east by Saturday and strengthening of the upper 
ridging over Texas. 
45 


Aviation... 
coverage from first impulse this morning near gls has diminished 
but expect coverage to increase around sunrise in the Gulf and hop 
inland by 15z. Have tried to narrow down the most favorable period 
for rain showers/thunderstorms and rain traversing the iah/hou terminals as 16-19z...though 
vicinity rain showers/thunderstorms and rain may linger until middle afternoon. By late afternoon 
expect coverage to decrease dramatically but after 09z expect more 
storms to form over the Gulf and again March inland tomorrow 
morning.
