Area forecast discussion...updated

Discussion...updated for 12z aviation.

Aviation...MVFR to IFR ceilings continue this morning at the 
ali/crp/vct taf sites. Anticipate a few more hours of stratus 
before mixing out as daytime heating commences. Southeast winds 
will once again pick up today with gusts between 25 and 30 knots 
during the afternoon. The gusty will winds should die down around 
sunset with stratus returning shortly thereafter. IFR ceilings 
possible but have only included MVFR ceilings for now. Haze may be 
an issue at times for crp/vct due to smoke over Mexico moving 
northward.

Previous discussion... /issued 407 am CDT Sat may 18 2013/ 


Short term (today through sunday)...another round of of low 
clouds/stratus underway this morning across south Texas. Stratus 
should thin out later this morning as mixing commences. 


Upper level ridge will continue to slide to the east today as 
system moves out of The Rockies. Temperatures should be a degree or two 
lower today as 850 temperatures are not as warm as yesterday. Highs will 
range from near 100 over the Rio Grande plains to near 90 across 
the Victoria Crossroads. Persistent surface trough over the High 
Plains will once again allow breezy south southeasterly winds this 
afternoon across most of the area. Also...retained a mention of 
patchy haze in the weather grids as smoke from agricultural 
burning in Mexico moves northward. 


Main forecast issue later this afternoon and evening will be 
whether or not convection can sneak into Webb County. Storms 
should develop to the northwest of the region along the surface trough/dryline 
and possibly over the higher terrain of Mexico. Main limiting 
factor for thunderstorms will be the strong cap in place as 700 
temperatures are between 12 and 13 degrees c over the Rio Grande plains. 
Will keep silent 10 probability of precipitation out west for now thinking cap will hold 
strong. 


Warm and capped atmosphere will still exist across the region on 
Sunday with similar temperatures to today. 


Long term (sunday night through friday)...not much change in the 
long term forecast period as strong cap still expected over the area 
through at least the first half of the period. A shortwave and 
associated surface boundary will move into the area mid-week...and 
there is still some question as to the strength of the cap at that 
time. 850 temperatures to decrease a bit...but 700 temperatures still look pretty 
warm. Did decide to add in a 20 pop for northern areas...with a 
weakened cap at least near the forecast area. Could see some 
development north...possibly encroaching on the forecast area. While 
the chance is small...it does exist. 


Temperatures hot early in the week may decrease a couple of degrees 
later in the week. Not too much change needed in the forecast.
