NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
635 PM CDT Friday may 22 2015 


Aviation... 
anticipating MVFR ceiling development overnight. Starting to see increase 
rain showers development off the coast. If this activity holds together...will 
have to amend some of the tafs this evening to add vcsh. Area should 
see increasing rain showers/thunderstorms and rain coverage during the day tomorrow. 


Extended period of rain showers/thunderstorms and rain should begin late Saturday night or 
early Sunday morning and persist into at least Monday or Tuesday.

Previous discussion... /issued 322 PM CDT Friday may 22 2015/ 


.Locally heavy rain expected Sunday and Monday... 


Discussion... 
at 2 PM...a warm front across central/southeast Texas will 
continue to move slowly north this evening. Scattered rain showers/thunderstorms and rain 
will continue to develop over the west/SW zones through the evening 
with precipitation waning after midnight. A weak upper level disturbance 
coupled with precipitable water values increasing to 1.80 inches...convective 
temperatures between 79-81 degrees and increasing upper level 
disturbance will produce scattered rain showers/thunderstorms and rain on Saturday. The NAM 
looks overly aggressive so will lean toward a GFS/European model (ecmwf) blend. Precipitable water 
values surge to 1.9-2.0 inches late Saturday night. An upper level 
trough over the intermountain west will move east Sat nite/Sunday. 
Forecast soundings show a saturated profile developing on Sunday with 
southeast Texas lying in a strong rrq and a S-southeast 40-45 knots low level jet. 
Numerous rain showers/thunderstorms and rain are expected on Sunday. Although storm motion will 
be pretty quick...training of storms will lead to some heavy 
rainfall totals on Sunday. Helicity values will range between 
170-200 so there is a threat for isolated tornadoes as well. 


Another upper level trough will dig further south toward El Paso by 
Monday morning and then move east-NE across Texas on Monday night. 
Some significant differences between the GFS and the European model (ecmwf) with 
their respective quantitative precipitation forecast bullseye Monday afternoon through Tuesday. The European model (ecmwf) 
is further south with a splitting jet structure and favors the maximum 
quantitative precipitation forecast over southeast Texas while the GFS shows the better divergence over North 
Texas. The Gem favors the European model (ecmwf) so leaned toward the further south 
solution and will maintain high rain chances Monday night/Tuesday. 
Training of storms is again expected with some heavy rainfall 
totals expected. The European model (ecmwf) quantitative precipitation forecast output exceeds 7 inches over 
Houston between Sunday and Tuesday. Unless forecast conditions change 
significantly...a Flash Flood Watch is expected to be issued early 
Saturday morning. 


Precipitable water values remain between 1.7-1.8 inches through the end of the 
week. Daytime heating should trigger scattered rain showers/thunderstorms and rain each day with 
precipitation waning with the loss of heating. A warm up will ensue Wednesday- 
Friday with maximum temperatures warming into the upper 80s. Another upper level 
trough will approach the state next weekend with more rain 
expected next Fri-sun. 43 


Hydrology... 
the Trinity River at Liberty remains in major flood and will 
remain in flood for the next couple of days. The Flood Warning at 
strane park ended earlier today and the river level will continue 
to drop. River levels also continue to drop on the West Fork of the 
san jac near Humble and Porter. Although conditions are improving in 
the short term...if heavy rain develops over the weekend... 
hydrologic issues could become a problem. Areas of possible 
concern include the West Fork of the San Jacinto...the Trinity 
River and the lower end of the Brazos river. Flash flood guidance 
has also improved. Rainfall rates will need to exceed three inches 
per hour to produce flash flooding. 43 


Climate... 
Huntsville has almost 11 inches of rain this month and today was 
the first day in the last 13 days without measurable rain. 
Huntsville recorded 12 consecutive days with rainfall 0.01 inches 
or greater (5/10-5/21). The Conroe ASOS has also tallied over 10 
inches of rain this month. On the flip side...Galveston has only 
measured 1.40 inches of rain during may which is about an inch 
below normal. 43 


Marine... 
conditions over the weekend are expected to deteriorate as the 
pressure gradient tightens and the persistent moderate onshore winds 
become stronger. Current thinking is that small craft conditions may 
develop as early as overnight Saturday night and persist through 
Sunday afternoon. Although the winds should drop off a bit on 
Monday...stormy conditions may keep seas elevated. 


The Tides may also become an issue on Sunday. The tide levels were 
from 0.5 to 1.0 feet above the predicted mean lower low water 
/MLLW/ levels this afternoon. These are expected to slowly increase 
to about 1 to 1.5 feet above the predicted MLLW levels by Sunday... 
and possibly level off or even slowly diminish on Monday if the 
winds diminish. However...swells on top of the above normal tide 
levels may lead to minor flooding issues on the Gulf facing beaches 
of the Bolivar Peninsula...especially low-lying areas of Highway 87.
