Severe Weather Alert Descriptions

 Public Information Statement  Statement as of 6:43 am CDT on October 1, 2014


... Warmer with a mix of wetter and drier than normal conditions...

September 2014 ended slightly warmer than normal across southeast
Texas. Two frontal passages brought enough rainfall to help ease the
year-to-date rainfall deficits at most of the climate sites. Seven
sites even ended September with above normal monthly rainfall.
Even so... 9-month double digit rainfall deficits were still being
experienced along the coastal counties.

None of the first-order climate sites recorded a 100-degree day in
September. With the arrival of autumn on the 22nd... this means the
Summer ended without a recorded 100-degree date for all four sites
in 2014. Although hobby Airport and the city of Galveston record
more years without a 100-degree date... 1983 was the last year that
all four locations failed to reach at least 100 degrees in the
same year. The following list gives the last year without a
100-degree date for the first-order climate sites.

City of Houston... ..1997
College Station... ..2004
city of Galveston... 2013
Houston hobby... ... .2010

Very dry conditions have persisted since the beginning of the year
west of the Colorado River. For example... the second-order climate
site at Palacios has only recorded three days since January 1st with
a daily rainfall of 1 inch or more... 1.00 on March 4th... 1.06 on may
13th... and 1.29 on June 26th. The following table lists the U.S.
Drought monitor indices as of September 23rd for the NWS Houston
County warning and forecast area...

Burleson d-0 western border

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
649 am CDT Wednesday Oct 1 2014 


Discussion... 
12z taf discussion in aviation section. 


&& 


Aviation... 
there are a couple of aviation concerns this morning. First there 
are low stratus clouds and fog which have led to periods of 
MVFR/IFR ceilings. Look for ceilings to improve once mixing occurs after 
sun rise. This will likely happen around 15-16z today and should 
see VFR ceilings after that through the afternoon. 


Second there is still some convection possible with showers 
already impacting areas east of a khou/kiah/kcxo line. Will carry 
vcsh for a few of the Houston and surrounding terminals. Main 
moisture axis remains east through the Sabine River basin and 
several mesoscale models support rain showers/thunderstorms and rain in these areas. Think 
if any thunderstorms and rain do develop it will be east of these terminals. 


Finally look for a similar pattern for Thursday morning. Have added 
taf lines to cover ceilings in the MVFR/IFR categories with possibly a 
few showers impacting the area. Do not see quite as much fog as 
winds should be closer to 5kts overnight.

Previous discussion... /issued 618 am CDT Wednesday Oct 1 2014/ 


Update... 
sending out an update to include isolated probability of precipitation farther inland. 


40 


Previous discussion... /issued 347 am CDT Wednesday Oct 1 2014/ 


Discussion... 
a weak warm front was moving inland early this morning. The best 
moisture axis was just east of the forecast area over the coastal 
waters south...east...and inland of the Sabine. The main upper 
level ridge was well to the south over the southern Gulf into 
Mexico. 


The models are fairly consistent in deepening the upper level 
trough over The Rockies as it pushes into the plains later today 
through Thursday. They do differ on the strength of the trough as 
it moves into Texas Thursday afternoon and night. A consensus 
keeps the best lift...dynamics...and instability over the northern 
part of the state and the Southern Plains. However...southeast Texas should 
experience a period of rain and thunderstorms as the southern end 
of the trough and an associated cold front pushes across the 
forecast area. 


Good warm air and moisture advection will lead to isolated to 
scattered convection today into early Thursday. Widespread rain 
and thunderstorms will then occur ahead of the front Thursday 
night. The GFS and European model (ecmwf) still are consistent in pushing the cold 
front into the northwestern set of counties after midnight...and 
then off the coast around or shortly after sunrise. Isolated 
strong storms are possible with the main threat gusty winds and 
minor flooding due to locally heavy downpours. For the most part 
the models are forecasting the storms to move quickly enough to 
keep the quantitative precipitation forecast under 1 inch for the event. 


After the front moves through a couple of cool and dry autumn 
days are in store for southeast Texas. Moisture return off of the Gulf 
will begin either late Sunday or early Monday. 


40 


Marine... 
southeast winds have developed this morning as low pressure 
continues to develop in the plains. Southerly winds today and 
Thursday will support gradually building seas approaching moderate 
levels. A cold front should push off the Upper Texas coast from late 
Friday morning through the evening hours. A line of storms may be 
possible with front as it pushes offshore. Strong northeast winds 
may develop behind the front in the offshore waters Friday night into 
Saturday morning. Small craft advisories may be needed during this 
time for 20 knot winds and seas building to near 7 feet. These 
conditions should quickly weaken late Saturday as high pressure 
moves east of the area. Southeast winds may develop later on 
Sunday.
