NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1214 PM CDT Wednesday Sep 17 2014 


Discussion... 
see 18z aviation discussion. 


&& 


Aviation... 
convective temperatures are between 82-86 degrees and precipitable water values remain 
between 2.1-2.3 inches. It won't take much lift to get convection 
to refire this afternoon but the first line that rolled through the 
area will keep things stable for a bit early this afternoon. Heating 
will allow rain showers/thunderstorms and rain to develop near kcll/kuts this afternoon. Aviation 
interests should be prepared for poor flying conditions beginning 
as early 09z Thursday as a strong shortwave dives southeast in the upper flow. 
Concerned that convection will fire before sunrise and affect 
areas from kcll to kiah by 12z. Activity will persist through much 
of the day. Could have used tempo all day but prefer to wait and 
see how the overnight system evolves. 43

Previous discussion... /issued 1107 am CDT Wednesday Sep 17 2014/ 


Update... 
after morning collaboration with wpc...there has been an ongoing 
adjustment of our probability of precipitation/wx/qpf grids. The main theme is for the 
threat of more area-wide heavy rainfall leading to flooding. The 
clusters that have passed across north-northwest Harris County have 
dropped large amounts of rain in a short amount of time...with an 
example of an inch within 15 minutes at the Cypress Creek at from 
249 hcfcd rain gauge. Clusters of slow-moving showers and storms 
forming within a highly moist tropical-in-nature air mass have the 
potential of putting down high rainfall amounts/rates over the 
next 24 to 36 hours. Ffg has hourly rates of two to three inches 
leading to flooding concerns...three to four inch amounts over 3 
to 6 hours will significantly heighten the flood threat...as well. 
In general...recent high rainfall rates/higher relative-volumetric 
soil content values reside over those counties east and southwest 
of the city so...along with Houston Metro/suburbs...these will be 
the areas that will most likely experience flooding issues. Points 
surrounding these locations can handle more rainfall...but with 
these recently high hourly rainfall rates of between a half of an 
inch to near near two inches...any community could be in The Hat 
in dealing with (flash) flooding. The rest of the forecast will 
remain unchanged...overcast with afternoon temperature extrema in 
the middle to upper 80s with morning readings falling into the middle 
70s. 31 


Previous discussion... /issued 446 am CDT Wednesday Sep 17 2014/ 


Discussion... 
not a lot of changes with the going forecast of continued rains for 
today/tomorrow. Very high precipitable waters noted over the region (~2.3") and 
not expecting that we will need a lot of heating for precipitation 
development to start again later this morning/aftn. As this 
moisture lingers into tomorrow we may have the remnants of Odile 
to deal with as well. Will likely keep with average rainfall totals 
from .5 to 1'... isolated 3-4" today through tonight. 


Rain chances to decrease some by Friday (on into the weekend) with 
weak upper ridging building in behind the upper trough (odile remnants). 
However will be keeping isolated/scattered probability of precipitation in for this period as the deep 
tropical moisture lingers over the area. Long range models keeping 
with the passage of the cold front at or above Monday...but with varying degrees 
of strength. European model (ecmwf) keeping its frontal passage a bit more robust than GFS at this time... 
but given the more consistent forecasts of a fairly deep north/northwesterly flow 
aloft will be leaning more towards the European model (ecmwf) for this time frame.
