NWS Forecaster Discussion




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


Discussion... 
all has quieted down this evening...and expect the rest of the evening 
and overnight hours to be quiet too. 


Main weather issue for the remainder of the week...over the weekend... 
and into the start of next week is going to be the heat and increasing 
heat index values. Through this period...expect to see more and more 
spots have afternoon high temperatures at or above 100 degrees and 
heat index values getting close to a 108 to 110 range. Heat advisories 
might be needed. 42

Previous discussion... /issued 630 PM CDT Tuesday Aug 4 2015/ 


Discussion... 
00z taf discussion in aviation section. 


Aviation... 
radar still shows a few showers west of Houston but should not 
impact any terminals the rest of the evening. Models hint at 
possible MVFR/IFR ceilings for several areas but think this is too 
aggressive. Hint at possible lower stratocu decks in the morning 
in tafs but not seeing a set up for prevailing lower ceilings. Precipitation 
water values look to go down a bit tomorrow to 1.8 inches. May 
still see a few showers but still low enough confidence to leave 
out any mention in tafs.

Previous discussion... /issued 338 PM CDT Tuesday Aug 4 2015/ 


Discussion... 
a very weak frontal boundary and a sea breeze moved inland earlier 
today. A more moist airmass was reflected by precipitable water/S up to around 2.0 
inches as seen on the Storm Prediction Center rap output. In addition to the surface 
boundaries...the nam12 and rap13 both showed weak vorticity 
advection moving overhead of the forecast area. This combination 
has generated isolated to scattered showers and thunderstorms. Am 
expecting the activity to diminish around sunset. 


Regarding rain chances for Wednesday...the middle and upper level 
ridge is forecast by the models to continue building overhead. 
Even so...the nam12 and high resolution models show isolated rain 
chances during the afternoon. Since the models have been 
consistent over the past couple of days...decided to go with a 15 
percent rain chance and mention isolated showers and thunderstorms 
possible during the afternoon associated with the sea breeze. Rain 
chances will diminish for the rest of this week and into Monday of 
next week as the upper level ridge builds over the state. 


The main issue through the upcoming weekend will be the building 
hot and humid airmass. The guidance and raw model output were 
forecasting actual daytime high temperatures over the inland 
counties as high as 99 to 102 in some places well inland through 
Saturday. The heat index may reach 103 to 108 over some locations 
on Wednesday and Friday...and then may possibly exceed 108 Friday 
and Saturday. Will continue to monitor the model trends as the 
week progresses.

Aviation... 
kept mention of precipitation for most sites for the rest of this afternoon given 
the trends. Models indicating that these high precipitable waters  (just over 2") to 
persist through tomorrow afternoon so we could see a repeat of today. Brief 
MVFR ceilings noted for some sites this morning. 41 


Marine... 
not a lot of changes with afternoon forecast package for the marine zones as 
the current weather pattern remains in place. The light/moderate onshore 
winds will persist with diurnal variations. Isolated/widely scattered possible 
early tomorrow given the lingering deeper moisture. 41
