NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
130 PM CDT Tuesday Sep 1 2015 


Update... 
sent out an updated forecast package with lowered probability of precipitation at almost all 
but southeast areas where locally heavy rainfall lingers. Also took 
several degrees off today's high temperatures based on current 
observation trends and cloud cover. 42 


&& 


Aviation... 
for the 18z tafs... main aviation concerns center around ongoing 
thunderstorms and rain/rain showers activity at the terminals with additional development 
expected again on Wednesday. 


Scattered to numerous thunderstorms associated with a middle to 
upper level disturbance continue to move across the terminals this 
afternoon. Bulk of activity is concentrated near and north of cxo 
with an additional broken line clearing the Houston terminals and 
southward. Starting to see additional activity develop over the 
Gulf and this will need to be monitored for the coastal sites this 
afternoon. Have thunderstorms in the vicinity at all terminals through 21z as activity 
exits the area... with another round of rain showers/thunderstorms and rain possible again 
early Wednesday morning over the coastal waters and spreading 
north into the terminals through Wednesday afternoon as the 
aforementioned disturbance draws closer to the region. 


Otherwise... light and variable to light and southerly winds 
expected for the terminals through the period with VFR conditions 
outside of thunderstorms and rain/rain showers activity. Some stronger wind gusts 
approaching 20 knots will be possible in convective activity as 
well as MVFR visibilities. Could see a few hours of MVFR 
visibilities at cxo again Wednesday morning as well at cxo... but 
only including a tempo mention at this time.

Previous discussion... 


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.
