NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
413 am CDT Tuesday Jul 29 2014 


Discussion... 
quiet conditions this morning across southeast Texas although a 
complex of thunderstorms off to our east has persisted overnight 
and is pushing off the western Louisiana coast. The surface front 
remains nearly stationary just to the north of our area but 
surface analysis shows evidence of a weak outflow boundary across 
our central counties leftover from the activity last night. Feel 
that with daytime heating this could serve as a focus for showers 
and thunderstorms to develop and have thus continued the low end 
chance probability of precipitation for today across the region. Temperatures should be a 
few degrees cooler today with some cloud cover and slightly lower 
heights. Heat index values will still reach into the triple digits 
with apparent temperatures of 100-103 this afternoon. 


Models have come into fairly good agreement with the timing of the 
front later this week. A shortwave trough over Utah this morning 
will rotate around the top of the ridge this week and then move 
southward...driving the front ahead of it. Best rain chances now 
appear to begin Thursday afternoon and continue overnight into 
Friday as the front moves into the region. The front will likely 
stall just offshore allowing for rain chances along the coast through 
the weekend. Winds become onshore again early next week with the 
models keeping slightly lower heights over the region as the base 
of the trough is trapped between two ridges. This will keep at 
least a slight chance for rain in the forecast through the middle 
of next week. 38 


&& 


Marine... 
light to moderate onshore winds will persist until a weak cold front 
and associated showers and thunderstorms move off the coast late 
Thursday night or early Friday morning. At this time...winds/seas 
are expected to remain below caution/advisory levels for the remainder 
of the week and through the upcoming weekend. 42
