NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
123 PM CDT Tuesday Aug 4 2015 


Update... 
another update to tweak rain chances. Storm Prediction Center WRF was analyzing 1.8 to 
2 inch precipitable water/S across the I-10 and southward corridor. Brief heavy 
downpours were accompanying the showers and isolated 
thunderstorms.

&& 


Previous discussion... /issued 1134 am CDT Tuesday Aug 4 2015/ 


Update... 
adjusted probability of precipitation further northward. Radar at 1130 am showed scattered 
showers developing west and northwest of metropolitan Houston. 


40 


Previous discussion... /issued 1016 am CDT Tuesday Aug 4 2015/ 


Discussion... 
a surface trough extended across the northwestern Gulf to near 
Galveston this morning. Radar showed that showers were trying to 
develop along and south of a line from near Wharton to 
Galveston...however subsidence due to the upper level ridge was 
appearing to keep the coverage very isolated. Model guidance 
varied for coverage this afternoon...from only an isolated shower 
or storm to more scattered coverage. The 12z nam12 continued its 
trend of bring isolated to scattered coverage close to the 
northern counties late this afternoon and early this evening. 
This looked to be due to the model showing a stronger shortwave 
trough on the northern side of the ridge. 


For now...the current forecast looks on track. Will watch trends 
and update later this morning or into the early afternoon if 
necessary.

Previous discussion... /issued 558 am CDT Tuesday Aug 4 2015/ 


Discussion... 
see 12z aviation discussion. 


Aviation... 
models (nam12/gfs) sending a bit of a mixed message this morning 
as forecast soundings show precipitable water values exceeding 2.10 inches at kiah 
this afternoon but model mass fields remain bare. Thought the rap 
initialized well and have leaned toward the rap today. Feel rain showers 
will generally stay over the southern taf sites and impact 
kgls...klbx and khou. VFR conds are expected today and most of 
tonight with some brief MVFR ceilings toward sunrise Wednesday. 43 


Previous discussion... /issued 408 am CDT Tuesday Aug 4 2015/ 


Discussion... 
early morning water vapor imagery and evening upper air analysis 
showed a flattened upper ridge stretching across the southwestern 
Continental U.S. Into Texas... with a compact shortwave trough moving across 
Colorado/Wyoming and an upper low over the Pacific spinning about 800 miles 
off the coast of northern California. A plume of very moist air 
/precipitable water values of 2.3 to 2.5 inches/ was located over 
Wharton... Jackson... and Matagorda counties per GOES sounder 
imagery. A few early morning showers had already begun to develop 
around Matagorda Bay within this more moist airmass and at least 
isolated showers will be possible south of Interstate 10 through 
the remainder of the morning. 


As southerly winds increase today... this more moist airmass will 
push farther inland. This... combined with daytime heating and the 
sea breeze... will keep the chance for isolated showers and 
thunderstorms in the forecast this afternoon and evening mainly 
along and south of a Columbus to Cleveland line. Cannot rule out 
an isolated stronger wind gust with this activity as dcape values 
approach 1000 j/kg this afternoon... but brief heavy downpours 
appear to be the most likely hazard given the extremely moist 
environment. High temperatures this afternoon are expected to top 
out in the low 90s along the coast... with middle to upper 90s 
farther inland. Heat index values may approach or slightly exceed 
105 degrees this afternoon... but will continue to increase during 
the week as afternoon temperatures rise. Elevated low level 
moisture will promote a limited cooldown overnight as temperatures 
only fall into the middle 70s to near 80. 


The upper ridge will shift east Wednesday as the low over the 
Pacific approaches the West Coast. High resolution guidance 
breaks out a few showers from coastal convergence along the coast 
Wednesday morning and again Wednesday afternoon along the sea 
breeze but only highlighting this activity with silent 10 probability of precipitation for 
now due to anticipated low coverage. Otherwise... another hot day 
expected Wednesday with temperatures similar to today. Heat index 
values are expected to remain below heat advisory criteria again 
on Wednesday... but heat advisory criteria may be met as early as 
Thursday for parts of the area. 


For the remainder of the forecast... hot and dry is probably the 
best way to describe the sensible weather pattern. The upper ridge 
building farther east will allow temperatures to rise into the low 
100s by the beginning of the weekend. Medium range guidance builds 
the center of the upper ridge over North Texas and into the 
arklatex by Saturday... with this feature maintaining control over 
the Southern Plains well into next week. 


Huffman 


Marine... 
high pressure over the eastern Gulf will produce a SW-S wind 
today. A weak boundary over the Gulf will serve as a focus for 
showers and isolated thunderstorms over the marine zones today. 
The gradient will begin to tighten Wednesday and Wednesday night 
as low pressure deepens over the Southern Plains. A light to 
occasionally moderate onshore flow will persist through next 
weekend. 43
