see 12z aviation discussion.

Aviation... 
brief and patchy ground fog will burn off within an hour of 
sunrise otherwise VFR conds expected today. Short term guidance 
continues to suggest that rain showers/thunderstorms and rain will increase in coverage 
later this morning once convective temperatures between 85-88 is met. 
Will carry thunderstorms in the vicinity for most taf sites between 17-22z. Skies should 
clear this evening with some potential for low clouds near kcll 
toward 01/12z. 43

Previous discussion... /issued 345 am CDT Tuesday Jun 30 2015/ 


Discussion... 
southerly low level winds continue to feed moist...unstable air 
into the region and with a northwest/weakly diffluent flow 
aloft... isolated to scattered showers /with an embedded 
thunderstorm or two/ continue to Blossom early this morning over 
southeast Texas and the western Gulf. 3 am CDT msas analysis 
shows a Theta-E maxima located along the Upper Texas coast this 
morning /where the highest coverage of showers and thunderstorms 
presently is/... and guidance continues to translate this feature 
towards the Sabine Pass through the remainder of the morning. 
Have increased rain chances over the coastal waters through the 
remainder of the morning hours in response. With daytime 
heating... highest shower and thunderstorm chances /30 to 40 probability of precipitation/ 
are expected to shift inland along and north of the sea breeze 
with coverage remaining isolated to scattered. Forecast soundings 
do show a relatively dry sub-cloud layer inland with evaporative 
cooling contributing to at least an isolated gusty wind threat 
from stronger thunderstorms. Brief heavy downpours will also be 
possible. 


For tonight... expect shower and thunderstorm activity to taper 
off inland with loss of daytime heating with isolated patchy fog 
possible in rural areas as skies clear and winds become light. 
Similar to this morning... carrying 20 to 30 probability of precipitation along the coast 
and over the coastal waters. For Wednesday... another round of 
diurnally driven showers and thunderstorms will be possible across 
the region with slightly lower precipitable water values /1.6-1.8 
tomorrow compare to 1.8-2.0 inches today/ contributing to slightly 
less coverage. 


Northwest flow aloft is expected to continue through the 
remainder of the week... but middle-level ridging building in from 
the east will result in enough subsidence to limit widespread rain 
chances in the Thursday/Friday timeframe. Heading into the 
upcoming Holiday weekend... a shortwave trough /located off the 
coast of British Columbia on early morning water vapor imagery/ is 
expected to reach Texas... with rain chances increasing across the 
region on Saturday and Sunday. Otherwise... temperatures are 
expected to remain near normal through the remainder of the week 
and into the Holiday weekend with highs in the upper 80s to low 
90s. 


Huffman 


Marine... 
strong high pressure over Florida coupled with a series 
of low pressure systems moving across the Central Plains will 
maintain light to moderate winds across the coastal waters through 
the end of the week. Moderate onshore winds are expected over the 
Holiday weekend with seas building to 4 to 6 feet offshore and 2 to 
4 feet near shore. 43
