Discussion... 
06z aviation discussion below. 


&& 


Aviation... 
from recent upper air soundings...it appears that most overnight 
convective activity will be fighting middle-level warming (cap) and 
dry air. Thus...vicinity showers and isolated thunder to affect 
most terminals through around 10z. Once line moves through...it 
should be subsident for a good part of Saturday. IFR/MVFR decks 
to lift to VFR by late morning...island haze backing offshore. 
Light southwest to south wind through day...clearing skies up north 
with possible return to near IFR by middle Saturday evening for more 
southern terminals. 31 


&& 


Previous discussion... /issued 1007 PM CDT Friday Apr 24 2015/ 


Discussion... 
latest radar composites show line of storms to the northwest with 
a cluster of supercell thunderstorms south of San Antonio. Expect 
line to the northwest to possibly clip Houston County with some 
gusty winds. The greater impact may be from the cluster of 
supercells south of San Antonio. These will likely continue east 
into our area overnight. 


Based on available soundings...think will see cells weaken somewhat 
has they track east and encounter greater inhibition. This is 
consistent with latest severe weather outlook and discussion from 
Storm Prediction Center which show western areas with a slight risk of severe...but marginal 
east. Have maintained likely probability of precipitation thinking most areas will see 
measurable rain overnight. Cant rule out isolated flooding issues 
with heavy downpours...but not thinking widespread. A few reports 
of wind damage or hail will also be possible...especially with the 
supercells if they can maintain themselves into our area...with 
greater chances over western zones. 46 


Previous discussion... /issued 728 PM CDT Friday Apr 24 2015/ 


Discussion... 
00z aviation discussion below. 


Aviation... 
scattered coastal County showers must likely forming under weak 
middle-level capping...maintaining their integrity within this extremely 
moist environment. The one rogue supercell north of kuts tonight 
quickly petered out as it headed northeast out of their terminal 
air space. A somewhat tricky forecast that was handled in more of 
a broadbrush manner due to the lack of return convection onset/ 
timing. Background winds are veering with height to support a 
sheared environment for any developing strong cell to rotate...but 
main threats from any short wave disturbance passage would be downburst 
winds with the secondary tornado threat. Higher rez short term 
modeling has a return swath of precipitation to affect southeast Texas 
tonight into early Saturday morning...lower confidence of occurrence 
and timing has just vcsh in place. Tempo30 thunder in the pre-dawn 
hours across more southern hubs but...if radar shows no significant 
west or southern Texas activity flaring up and moving towards the 
region...may need to downgrade this to just vc by the 06z package 
time. Overnight/early Saturday periods of IFR to MVFR ceilings once 
again...with a thicker haze to impact the island tonight through 
early Saturday. Other than a passing pocket of early Saturday 
precipitation lowering cats down to MVFR...expect a more southwest 
wind with generally VFR ceilings. 31 


Previous discussion... /issued 330 PM CDT Friday Apr 24 2015/ 


Discussion... 
another complex forecast for the area tonight through Monday as 
region remains under active...moist southwest flow aloft. Some 
disagreement in the high res models regarding convective 
potential/evolution overnight...although expect storms firing 
across northern/central Texas this afternoon/evening to continue into at 
least parts of southeastern Texas overnight. Isolated storms can also be 
expected to develop across the northern counties this evening with 
moderate instability and little or no capping in place across a 
broad warm sector over southeastern Texas. Showers already trying to get 
going around cll to Huntsville. Shear remains impressive area-wide 
/effective shear at or above 50kt common/...thus any storm which can get 
rooted will have impressive deep layer shear and instability to 
work with. Timing remains problematic...however expect northern/western 
counties to see stronger storms this evening into the early night- 
time hours with slightly delayed start farther south and east 
depending on how storms evolve. Could see one or more areas/lines 
of storms with activity possibly dropping southeastward out of northern Texas and 
eastward out of central Texas tonight. Have gone with likely probability of precipitation across 
the area tonight with lingering threat near the coast through the 
middle morning Saturday before activity shifts away from the area. 
Large hail/damaging winds and heavy rain will be primary 
threats...especially if any more organized convection evolves. At 
this time...expect heavy rain threat will remain localized as the 
strong flow aloft keeps storms moving. However...we will have to 
closely watch for backbuilding. 


Cant rule out a few showers and thunderstorms Saturday afternoon as more 
westerly low flow and breaks in cloud push afternoon temperatures to near 90f in 
some areas. However...overall expect tomorrow into Sunday to see 
less activity. That changes as we get into Sunday night/Monday as 
main upper low finally begins to eject across the area. Should see 
yet another round of heavy rain/severe threat with thunderstorms 
into early Tuesday. After this last round early in the 
week...models continue to show a very pleasant week for southeast 
Texas next week. 48

made some tweaks to the tafs for this aftn/evening. For the most 
part have taken the mention of precipitation out for the rest of the afternoon 
(save for the lbx where there might be some isolated development com- 
ing in from the sw). Short-term models in general agreement with 
the timing for the start of the next batch of storms tonight at or above 
06z. 41
