NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Houston/Galveston Texas 
305 PM CDT sun Mar 29 2015 


Discussion... 
at 2 PM...a cold front extended from okc to an area of low 
pressure near Midland. There is a 10 mb pressure difference across 
central and East Texas and this responsible for the strong winds 
this afternoon. Am expecting clouds to increase again overnight into 
Monday morning. The cold front will push south and is expected to 
stall north of the area. Moisture levels will deepen on Monday and 
precipitable water values will reach 1.3 inches over the north and 1.1 inches 
south. Forecast soundings reveal very dry air above 700 mb and not 
much in the way of low level saturation. Still the proximity of 
the weak boundary coupled with higher moisture levels should yield 
a few showers over the north on Monday. Lowered probability of precipitation on Tuesday as 
precipitable water values drop to less than an inch and forecast soundings show 
extremely dry air at 850 mb and more dry air near 700 mb. Moisture 
trapped beneath a strong cap will probably limit mixing and keep 
mostly cloudy skies in place. 


A short wave trough will move east Tuesday night and approach southeast Texas on 
Wednesday. The European model (ecmwf)/Canadian continue to advertise widespread 
rainfall while the GFS/NAM are dry. The ec/can are sharper with 
the trough and further south while the GFS is flatter and further 
north. Not sure how this will eventually play out as the GFS and 
European model (ecmwf) have both shown good run to run consistency. The jet 
dynamics of the European model (ecmwf) look to be trending closer to the GFS solution 
today but moisture levels in the NAM are trending closer to the 
European model (ecmwf). Confidence is low on what will transpire on Wednesday so 
feel the best course of action is to leave the grids as is and 
wait for more consistency. 


The European model (ecmwf) and the GFS differ a bit with timing on the next front 
which will cross the coast next Friday night or early Saturday. The 
ec is now about 12 hours faster than the GFS. For now...just 
split the difference with regard to timing. The front should 
trigger a few showers as it crosses the region. A building upper 
level ridge will expand over Mexico next weekend and an upper 
level disturbance will scoot east on the north side of the 
building ridge. This will bring a chance of rain showers/thunderstorms and rain late Sat 
into Sunday across most of southeast Texas. 43 


&& 


Marine... 
today's fairly tight onshore pressure gradient will relax a bit 
early in the work week as eastern based high pressure expands 
further west into the region. Caution criteria over the western 
offshore waters as winds stay at or around 15 knots...seas remain 
near the 5 foot mark through early Monday morning. A week of onshore 
flow before a weekend front backs winds around to the north(east). 
Middle week rain chances are still high in anticipation of the approach 
and passage of an upper level trough. 31
