Aviation... 
south southeast winds will increase slightly for this afternoon as 
warm air advection continues. Expect scattered middle level deck to 
gradually lower and fill in this evening as moisture increases. 
Shower coverage continues to be less than models forecast for 
today so will hold off on vcsh for now. Greater shower coverage 
expected overnight into Friday morning. 38

Previous discussion... /issued 1017 am CST Thursday Nov 20 2014/ 


Update... 
see discussion for morning update. 


Discussion... 
surface high that allowed for cold temperatures the last couple of 
days is now well off to the east with return flow established 
across the area. Current amdar soundings showing very saturated 
800 to 900 mb layer with a substantial cap at 750 mb. At 250 mb 
the Omega block that allowed for the cold air to move into our 
area has started to erode and push to the east. At 700 mb a weak 
boundary was analyzed across central Texas. Due to increasing 850 
mb temperatures have gone ahead a bumped up high temperatures a 
bit. Also am expecting weak isentropic upglide to continue today 
allowing for weak underneath the cap showers to persist this 
afternoon. Have only made minor changes to pop grids to capture 
current trends. Overall current forecast is in good shape and made 
only minor changes. 23 


Previous discussion... /issued 507 am CST Thursday Nov 20 2014/ 


Discussion... 
the warm air advection pattern has begun with the region falling 
under a pronounced southeasterly fetch over the next few days. Middle 
to upper 40 interior dew points will increase into the mean upper 
50s by the close of the day...thickening cloud cover and a higher 
chance for scattered showers. The highest probability of showers 
will be focused along the western corridor of the County Warning Area...especially 
over the southwestern forecast area or those counties surrounding 
Matagorda Bay. Higher rez modeling is focusing quantitative precipitation forecast in this area as 
it develops a weak cyclonic circulation near Matagorda Bay. 
Isentropic upglide will become more efficient over the next 36 
hours as SW-S winds along the applicable Theta surface produces 
sub 20 condensation pressure deficits and further saturates a 
deeper column = more areal showers. 15 to 20 knot near surface 
winds making it ashore and creating frictional speed convergence 
will saturate the lower layer to produce streamer-like showers... 
transitioning further north during the warmth of the day. As the 
column saturates up through Friday...there is a higher chance for 
more widespread areal rain showers coverage tomorrow. Very mild and warm 
conditions with an amped up south wind...60s in the morning warming 
into the lower to middle 70s. Quite the change in a very short 
time! For perspective...please refer to the climate section below. 


Saturday is still the target day for strong to severe weather. 
All of the ingredients are in place for a possible active weather 
day...from the high shear to the impressive upper level divergence 
created by a deep shortwave trough passage across central and NE 
Texas. The region displays Two Peaks in tornado frequency...one in 
the month of may and the other in November. The natural tendency 
to desire high thermodynamic indices needs to be tempered due to 
the season...cool season severe weather can run on much lower 
Thermo drivers. Low topped tornadoes can and will occur during 
these cooler months under lower convective temperatures...cape... 
l... season tornado climatology shows that a range 
of 500-1500 ml cape occurs during tornadic events with the 50th 
quartile falling around 1200....effective shear in the low to middle 
40s...srh in the 100 to 300 range. All of these values fall in 
line with the latest soundings forecasts. If the region can see some sun 
behind a lifting warm front early Saturday...there may be a higher 
threat for severe to be achieved. High total shear values with fast 
moving storm motion(s) leans the primarily threat towards wind 
damage. Lower wbz heights may introduce a hail threat...as well. 
Regardless of the Thermo and dynamic indices the extremely high positive vorticity advection 
perpendicular to the flow of such a sharp middle-upper trough should 
kick off at least strong discrete cells. These cells may evolve into 
a more organized mesoscale convective system or qcls that adversely impacts the area from as 
early as noon through as late as Saturday evening. 


Winds quickly become northwest in the trough's wake Sunday...dry and 
stable under a northwest flow to begin Thanksgiving week. The surface cold 
front will pass across the region early Monday morning...a cooler 
and dry air mass early in the work week will keep mornings in the 
40s with afternoons warming into the average low to middle 60s. 
Thanksgiving day is forecast to be pleasant...mostly sunny with 
afternoon temperatures in the average upper 60s. 31 


Aviation... 
mainly VFR conditions across the region this morning with ceilings 
generally between 4000-7000k ft, but 2800-4000 across western areas. 
Models insist on some rapid low level moisture return today west/ some 
areas transitioning to MVFR as scattered areas of -ra develop. Not real 
confident regarding either since rigs in the Gulf not displaying 
much difference than what we see inland at this time. So will generally 
keep more optimistic tafs in place for the short term and see how 
things play out. Will advertise gradually lower ceilings tonight... 
probably into MVFR territory...but again more optimistic than 
some of the IFR suggestions posed by some of the models. 47 




Marine... 
southeast winds increase later today and should support caution 
criteria offshore later this afternoon and advisory criteria tonight. 
Advsy conditions will then persist into Saturday in advance of an 
approaching strong storm system. By then...seas should be 5-8 feet 
with southeast/S winds of 17-23 knots and a long fetch. Strong to severe 
thunderstorms may be possible over the coastal waters Saturday 
afternoon and night as the storm system passes through. Moderate SW 
flow can be expected in its wake Sat night & Sunday. Next front 
penciled in to push off the coast late Sunday night. 47 


Climate... Houston recorded a record low of 30 degrees Wednesday 
morning. The high temperature Wednesday afternoon was 69 degrees. 
The high is significant because high temperatures have not exceeded 
58 degrees since Nov 11th. The last time Houston recorded 7 
consecutive days with high temperatures at or below 58 degrees during the 
month of November was back in 1907. The temperature was below 58 
degrees between 11/11/1901 and 11/18/1907. That was also the last 
time (until this year) that Houston suffered a daily average 
temperature departure greater than 10 degrees per day for eight 
consecutive days.
