 Public Information Statement  Statement as of 7:55 am CDT on April 1, 2015



... March 2015 was much wetter than normal...

The month of March was much wetter than normal across all of
southeast Texas. In turn... the rainy periods during the month
helped bring about a month of near normal daily average
temperatures. The wet conditions reversed the results of a very
dry February and raised most year-to-date rainfall at the climate
sites to at or above normal.

Rainfall for March at the first-order climate sites actually
ranked in the top 15 wettest months on record. Hobby Airport
ranked 7th... the city of Galveston 8th... College Station 11th...
and the city of Houston ranked 13th. The following table lists
the top 15 wettest months of March on record for each first-order
climate site.

The rainfall reversed a trend that has seen most of the past 15
months see below normal rainfall. Still... the city of Houston
has now only had four months out of 15 with above normal
precipitation... while College Station... hobby Airport... and
Galveston have only had five months with above normal rainfall
during the same 15 month span. For this year... all of the first-
and second-order climate sites received above normal rainfall in
March. Of the 12 sites... 11 received in excess of 2 inches above
normal... five recording more than 3... two more than 4... and one
with greater than 6 inches above normal! The following table gives
the rainfall with the deficits for the first three months of 2015.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
635 am CDT Wednesday Apr 1 2015 


Aviation... 
there is a mix of MVFR/IFR ceilings and visibilities across southeast Texas early 
this morning. 12z tafs have area becoming VFR later this morning and 
on through this afternoon...but it is not out of the question that MVFR 
ceilings could persist longer than anticipated. Area radars are showing 
rain showers/thunderstorms and rain already developing across deep south and south central Texas... 
and this activity is moving to the northeast toward our area. Went ahead 
and added thunderstorms in the vicinity to the tafs for this afternoon to account for this convection. 
Reduced ceilings/visibilities will be possible in association with the 
shra/tsra. Tafs have ceilings/visibilities coming back down to MVFR/IFR 
levels tonight through early tomorrow morning. 42 
&& 


Previous discussion... /issued 558 am CDT Wednesday Apr 1 2015/ 


Update... 
updated to start chances for rain earlier. Isolated showers may 
begin to affect the western counties before middle morning.

Previous discussion... /issued 422 am CDT Wednesday Apr 1 2015/ 


Discussion... 
still looking at three main events over the next week...an upper 
level shortwave today...a cold frontal passage on Friday...and 
then a series of upper level systems over the weekend and early 
next week. 


The first upper level shortwave trough was moving into western 
part of Texas early this morning. The system will be running up 
against a low-level high pressure ridge that extended from the 
northern Gulf of Mexico into southeastern Texas. The models 
differed a bit on rainfall coverage with the event today. Liked a 
combination of the high resolution models with the GFS and nam12. 
The nambufr and gfsbufr forecast soundings actually show a decent 
dry layer that does not erode until late afternoon. The rap13 and 
nam12 bring coverage into the southwestern counties by early 
afternoon. Decided to take a compromise and lower the probability of precipitation for 
this morning and then bring the best chances for showers and 
thunderstorms this afternoon. The upper level system will be out 
of the area by middle evening. 


A couple of warm days...especially Friday...will then occur as a 
southwesterly flow develops. The models are then in agreement with 
at least chance probability of precipitation ahead of the cold front that will move 
through Friday afternoon and evening. All of the models actually 
diminish the rain chances Friday night and Saturday. The GFS and 
European model (ecmwf) differ on the strength of the upper level shortwave troughs 
on Sunday the with GFS the more aggressive model of the two. Took 
a consensus of both models for the rain forecast both days. 
Tuesday is looking to be warmer as a middle and upper level high 
pressure ridge developing over the Gulf extends northward into 
southeast Texas.

Climate... 
March ended being one of the top 15 wettest months on record. 
Here is a listing for the first-order climate sites... 


Hobby Airport.......6.25 ranked 7th highest 
city of Houston.....6.34 ranked 13th highest 
city of Galveston...7.69 ranked 8th highest 
College Station.....5.83 ranked 11th highest 


The rainfall helped alleviate the drought conditions that were 
experienced over Jackson...Wharton...and Matagorda counties. 
Portions of these areas were under a moderate drought earlier this 
year. The rainfall during the month of March brought improvement 
to where only Jackson County was under abnormally dry conditions 
at the end of the month. This was due mainly to long term 
hydrological drought conditions on the local river system. 


40 


Marine... 
moderate south winds will persist through the end of the week. 
Speeds could get close to caution levels through Thursday night... 
but a majority of the area should peak in a 10 to 15 knot range. 
The next cold front is still on schedule to race off the coast and 
through the coastal waters late Friday night through early Saturday 
morning with moderate to strong northeast winds and building seas 
in its wake. Caution flags and advisories will likely be needed 
behind the front...and parts of the coastal waters could see 
sustained winds around 25 knots and seas up to 8 feet early on 
Saturday. Winds behind the front will weaken Saturday night and 
on into Sunday and become more east and southeast...and this 
moderate onshore flow will be in the forecast for the start of 
next week. 42
