NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
1014 am CDT Sat Jul 4 2015 


Update... 
current forecast in good shape with expected development of 
scattered showers and thunderstorms later this morning into the 
early evening...primarily across northern and eastern counties. 
Location and exact timing of these short-lived storms remains too 
difficult to pin down at this time. Overall...a warm and humid 
fouth of July is on tap with breezy south-southwest winds. 


Tail end of well defined shortwave trough on WV imagery 
approaching the middle south will skirt southeastern Texas today may boost deep 
ascent today. Initial development by early afternoon will likely 
be tied closer to the sea breeze...although moderate larger scale 
S-SW flow throughout the boundary layer across the area may tend 
to limit overall convergence today. With little focus 
elsewhere...later day development will be tougher to pin down and 
may become focused along residual outflow from earlier day storms. 
Observed and forecast soundings are favorable for a few stronger 
storms once temperatures push through the upper 80s with isolated 
strong/damaging wind the primary concern...along with lightning 
and brief heavy rainfall. High-res guidance suggests most of the 
thunderstorm development will occur between 12p/1p through 7p/8p.

Previous discussion... /issued 426 am CDT Sat Jul 4 2015/ 


Discussion... 
at 3 am...a surface trough extended from central Arkansas into 
extreme North Texas. Speed convergence along the coast has helped 
to produce a few showers in the coastal counties early this 
morning and these will end shortly after sunrise. At 850 mb...a 
trough of low pressure extended across north Arkansas into south 
Oklahoma with deeper moisture over northern Louisiana and a second 
area of deeper moisture along the Rio Grande Valley. A 700 mb 
trough extended into NE Texas with subtle warming at both lch and 
crp. At 500 mb...a tough of low pressure extended into south 
central Texas. Winds at 250 mb were splitting over East Texas and 
models keep a divergent wind field in place through the day. 


Forecast soundings forecast precipitable water values to increase through the day peaking 
between 1.9 and 2.3 inches. Cape values are prognosticated to increase to 
around 3000 j/kg and lifted indice's are -7 to -10. Convective temperatures are 
between 86 and 90 degrees so daytime heating coupled with the 
weakness at 700-500 mb and a divergent upper level wind field 
should yield a good chance of showers and thunderstorms today. 
Models are not aggressive with rain chances today but think 
convection will become more widespread by afternoon. Some of the storms 
will be on the strong/severe side with cape at or above 3000 and an 
inverted v signature evident on forecast soundings. Have added some 
possibly severe to the weather grids/zones for the eastern half of the 
County Warning Area for this afternoon. Conds should clear in time for area 
fireworks tonight with the loss of daytime heating and the upper 
trough shifting east. 


On Sunday...the trough is further east and upper level ridging 
tries to build over the state. Precipitable water values remain between 1.7-1.9 
inches with little capping in place. Forecast soundings show a 
considerably drier moisture profile and convective temperatures around 
90. Rain chances will be considerably lower tomorrow but am 
hesitant to completely pull probability of precipitation so will maintain the 20 probability of precipitation 
already in the grids. The week ahead looks mainly dry with precipitable water 
values hovering around 1.4-1.5 inches. An upper level ridge will 
try to develop middle week but it looks like this feature really 
doesn't develop until the end of the week. Temperatures will remain near 
climatology early in the week and gradually warm toward the end of the 
week. Middle 90s look like a possibility by next Thursday/Friday with warmer 
temperatures possible for next weekend. 43 


Marine... 


Scattered showers in the Gulf waters moving north or northeast with 
time should wane by 8-9 am. Southerly flow is well established 
between high pressure over the eastern Gulf and Lee side troughing 
that eventually moves out into the plains by early in the week. This 
should maintain southerly winds in the 12-17kt range through 
Wednesday night. Seas of 2-4 feet nearshore and 3 to 6 feet well 
offshore. The showers should return again tomorrow morning but after 
that expect decreasing coverage of storms. One possible fly in that 
ointment would be a disturbance rounding the upper ridge and nudging 
storms out of la into the coastal waters Sunday afternoon...more 
likely the storms would weaken as it moves into subsidence aloft but 
will be keeping an eye on the possibility. Tropics look quiet 
through the week. 
45 


Aviation... 


Patchy MVFR conditions early this morning a combination of light fog 
and broken St at 2000-3000ft. Showers near the coast should struggle to 
penetrate inland early this morning but as ll flow backs with 
heating the showers should begin the inland creep offset by capping. 
Will keep vcsh in the coastal sites through 15-16z then transition 
inland sites to vcsh/vcts. Expect that around 17-18z most sites 
should near convective temperatures and isolated thunderstorm coverage and 
intensity should increase through the remainder of the afternoon. 
Gusty winds in pulse type storms a decent threat and plan to keep 
the gusty winds in the terminals accompanying thunderstorms and rain. At the moment 
think that 20-23z should be the greatest chance at iah...an hour or 
so earlier for hou and hour later for cxo as seabreeze noses inland 
and deeper moisture arrives.
