 Public Information Statement  Statement as of 11:52 PM CST on February 28, 2015


     ... February 2015 was cooler and drier than normal...

February 2015 has come to an end and the month ended on a very cool
note. The average monthly temperature was about 3 degrees cooler
than the 30 year normals. The year to date average temperature is
also averaging about 3 degrees cooler than normal. Despite the
cooler than normal temperatures... there were no record low
temperatures established. However... College Station did establish
a new record low maximum temperature of 42 degrees on the 27th.

Rainfall during the month was paltry with monthly totals failing to
tally an inch of rain. Southeast Texas has endured a five week
dry spell with the last major rain event occurring back on
January 22nd. Actually the dry spell has lasted quite a bit longer
than five weeks. Over the last 14 months... the city of Houston has
endured 11 months of below normal rainfall and only 3 months with
above normal rainfall. Rainfall has also been below normal for the
past six years with this extended dry period beginning in October
2008. The city of Galveston... Houston hobby Airport and College
Station reported 10 out of the last 14 months with below normal
rainfall and only four months with above normal rainfall.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
352 am CST sun Mar 1 2015 


Discussion... 
areas of light rain continue to develop early this morning across 
southeast Texas and adjacent coastal waters and move off to the north 
and northeast. Anticipate only subtle changes in the weather pattern 
over the next couple of days...resulting in periods of mainly light 
rain or rain showers along with areas of fog. Some of the fog could 
become dense...and dense fog advisories might be needed. Might even 
see a thunderstorm or two...but the greatest risk area for that is 
expected to be off to our north and northeast. With this forecast 
package...have continued yesterday's trend of slightly lowering 
temperatures. A significant warm up is still in store for the area 
on Tuesday as south winds finally return and strengthen ahead of the 
area's next cold front. It still looks like this strong front will 
move through southeast Texas on Wednesday with temperatures falling 
behind the boundary. A tight pressure gradient behind the front will 
bring breezy/windy conditions to the area...and would not be surprised 
if we end up needing a Wind Advisory Wednesday night on into Thursday 
morning. Conditions still look favorable for possible frozen precipitation 
up north Wednesday night through Thursday morning. There is a lot of 
time for this forecast to change...so stay tuned. 42 


&& 


Marine... 
the development and slow progression of a nearshore trough...and its 
associated warm frontal boundary moving onto the Upper Texas coast... 
has and will fortify the formation of sea fog and periods of 
light rain or drizzle. Light to occasionally moderate southeast 
winds with offshore seas falling below caution criteria through 
the day. As this western Gulf trough washes out late Monday...fog 
and periods of light precipitation will linger. As northwestern 
Texas surface pressures lower ahead of the next cold front on 
Tuesday... onshore winds will strengthen to near caution levels. 
The cold frontal passage is timed to pass across the local waters 
Wednesday night. This is forecast to be a strong front as a cold 
shot of northern plains air and a tight offshore gradient pushes 
winds to near gale force Thursday morning. 31
