NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
439 am CDT Friday Apr 29 2016 


Discussion... 
today: 
fairly uneventful morning anticipated. An area of deep tropical 
moisture (pw's 2-2.2") situated in the SW Gulf will be making its 
way up the coast and into southeast Texas during the late morning and 
afternoon hours. By early afternoon...there's pretty good 
agreement in guidance showing showers/storms being initiated along 
dryline in cntl Texas and making their way eastward into southeast Texas 
during the late afternoon and evening hours. Should be enough 
instability & shear by that time for some severe storms to be a 
threat (hail, wind, isolated tornadoes all a possibility). Flash 
flooding is also a concern in association with convective cells. 
The more favored location for this to occur appears to generally 
be northwest of Highway 59. 


This evening into Saturday morning: 
this is where considerable uncertainty enters the picture on how 
things will evolve. Best case scenario will be for the 
line/complex of strong to severe storms to continue moving east-southeast 
across the remainder of the region with a break in the precipitation in 
its wake. Worst case scenario...which cannot be ruled out 
either...is for the the north-to-south oriented portion of the 
line of storms to race eastward leaving the southern portion of 
the line behind as it transitions into a more west-to-east 
orientation somewhere across the area. Should this occur...it'll 
become situated roughly parallel to the upper flow and movement 
could substantially slow. Favorable upper level divergence 
overhead into midday Saturday with sustained moderate inflow 
feeding perpendicular to such a boundary could lead to a 
significant flash flood threat wherever such a boundary ends up. 
Again...that would be a worst case situation. Anything in between 
is possible. Unfortunately...many times these events play out on 
smaller scale details than what models depict...so overall 
confidence in any one solution isn't very high and will have to 
keep an eye on trends. Bottom line is ground is nearly saturated 
from recent rains. Even 35-50 miles per hour winds will be a risk of Downing 
trees. Stronger cells will also produce efficient rainfall rates. 
Quick runoff will produce a flash flood threat. Will leave Flash Flood Watch as/is. 


Rest of Saturday & sunday: 
will be highly dependent where potential boundaries are situated & will 
have to see what evolves tonight. A cool front is forecast to begin 
pushing into southeast Texas late Saturday. Suspect even if there is a break 
in the action during the day it'll recover enough for at least 
scattered precipitation to redevelop along and south of the front Saturday 
night & Sunday. 


Monday through Tuesday morning: 
another series of upper impulses moves into the region from the 
western trough. Expect precipitation to become widespread once again. 
Frontal boundary will be lingering nearby and probably serve as a 
continued focus for precipitation. Potential for some more 
unneeded heavy rains will continue to be monitored. 


Wednesday through friday: 
things should begin to dry out as upper ridge gradually builds 
overhead. 47 


&& 


Marine... 
generally moderate onshore winds expected today in response to the 
storm system developing over the Southern Plains. Winds set to increase 
by tonight as the system begins moving east and helps to draw dis- 
turbances over the area from the west-southwest. Have kept caution flags positive- 
ted in place through this afternoon...and should be upgraded to a Small 
Craft Advisory (especially for the coastal waters) by this evening. 
Winds/seas could be further elevated in/near scattered storms today into 
tonight. 


Have also hoisted a coastal Flood Advisory for today for beaches/ 
intercoastal waterway down the Brazoria County coastline. Onshore 
winds have help to pile up water onto roadways/low-lying areas in 
these areas during high tide...especially close to the Highway 87 
and 124 connection near the Bolivar Peninsula. 41 


&& 


Aviation... 
strong warm air advection has produced some widely scattered -dz/-ra over southeast Texas overnight 
along with IFR to MVFR conditions. We should see ceilings lift some through 
the late morning/early afternoon hours as the deep onshore winds persist. 
We could see VFR conditions during the afternoon with vcsh...but increas- 
ed precipitation chances tonight should help to lower ceilings. Timing of the storms 
tonight will be the main issue so will likely keep with thunderstorms in the vicinity wording 
for now. 41
