NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
628 am CDT Monday Sep 1 2014 


Discussion... 
see aviation for 12z taf discussion. 


&& 


Aviation... 
IFR ceilings have overspread the northern taf sites this morning but 
should begin to improve quickly after sunrise. Light rain showers offshore 
approaching gls and should gradually spread inland through the 
morning hours. Less moisture to work with today but could still 
see some isolated activity inland. Instability high enough to go 
with thunderstorms in the vicinity through the early afternoon for metropolitan area taf sites. 
Another round of MVFR/IFR ceilings possible again early Tuesday. 38 


&& 


Previous discussion... /issued 432 am CDT Monday Sep 1 2014/ 


Discussion... 
low pressure in the plains should deepen today and support 
stronger southeast winds at the surface. Tropical moisture has decreased some 
across the area but precipitation water values still remain around 1.9-2 
inches per soundings and GOES sounder data. Upper level trough 
over the plains will pull towards the Great Lakes with a trailing 
shortwave moving across the c plains by this afternoon. Upper 
level ridge is in the process of becoming more established over 
the area as heights should rise today. Upper level ridge should 
remain broad and flat across the southern U.S. Into Tue/Wed. 


Infrared satellite imagery over the Caribbean shows a tropical wave 
moving over the Yucatan this morning. This wave should emerge into 
the Bay of Campeche tonight into Tuesday. The GFS/European model (ecmwf) agree with 
keeping the tropical wave an open wave moving towards the Mexican 
coast. The NAM and Canadian close off a circulation with the 
possibility of a tropical storm forming before landfall Tuesday night 
into Wednesday. Canadian is most aggressive. NHC gives the system a 60 
percent chance of tropical cyclone development the next 48hrs and 
70 percent chance over next 5 days. The environment is at least 
looking more favorable for development. Latest forecasts have all 
been very consistent with bringing the system regardless of 
strength into the Mexico coast. Greatest impact from this system 
on the Texas coast will be increasing seas and tropical moisture. 
While the upper level ridge will be in place...there still should 
be plenty of moisture for thunderstorm chances Tuesday/Wednesday so will 
keep 30/40 probability of precipitation in the forecast with 50 probability of precipitation on Tuesday. Locally heavy 
rainfall will again be possible with intense rain rates in 
stronger storms. 


The rest of the week will be a battle between subsidence from the 
upper level ridge and convection developing due to day time 
heating with the tropical moisture. Forecast will at least keep 20 
probability of precipitation for the of the week into the coming weekend. Upper level 
ridge will remain stretched over Texas with weakly amplified almost 
zonal jet stream flow across the northern half of the U.S. Main 
differences in the GFS/European model (ecmwf) for the extended forecast is a back 
door front coming into the area per the European model (ecmwf). This will still be 
difficult to do since the pattern is still weakly amplified and 
the ridge may be strong enough to keep the front out of the area. 


Marine... 
isolated showers will continue across the coastal waters today. 
Expect onshore winds to persist through much of the week with 
speeds increasing beginning late tonight as pressures begin to 
lower across the Bay of Campeche. May need caution flags as early 
as tonight but likely beginning on Tuesday. Approaching swells 
will bring wave heights up by another foot or two across the 
offshore waters by Wednesday. 38
