Aviation... 
shortwave trough will cross the region this evening and remaining 
rain showers/thunderstorms and rain activity will move NE and away from area by 02z. Forecast 
soundings all rather bullish with low ceilings developing overnight. 
Feel winds just off the surface favor more of a low ceilings so will 
carry MVFR ceilings overnight. Ceilings will mix out between 17-19z 
Thursday with VFR conds expected Thursday aftn/evening. MVFR ceilings 
are expected again tomorrow night. South winds on Thursday will 
remain strong and gusty. 43

Previous discussion... /issued 303 PM CDT Wednesday Apr 1 2015/ 


Discussion... 
upper level short wave trough on water vapor imagery continues to 
move over southeast Texas this afternoon. Radar has shown a few storms 
across the area but are fairly widely scattered producing close to 
a quarter inch of rainfall on average. Boundary layer remains 
rather moist. Possible that thunderstorm activity will continue to 
develop through the evening as the wave passes over the area. 
Activity should be ending around 02-03z as the wave pushes east. 
Latest rap/hrrr runs seem to be initializing with too much 
convection compared to recent radar trends. Current probability of precipitation look on 
track with 30/40 percent and then dropping to 20 percent tonight. 


Models continue to be fairly consistent with the next frontal 
passage coming late Friday. The main differences will be expected 
rainfall with the front. The GFS/European model (ecmwf) look to be a bit more on 
the wet side than the NAM for the 12z runs. Upper level support 
looks rather weak but still a fairly strong front for early April. 
Model sounding show some capping to overcome but expect 
frontogentic lift to be sufficient for thunderstorm development. 
Instability will be limited and combined with capping/dry air 
above 700mb...not looking for much activity to develop. Suspect 
there will be a thin line of showers and embedded thunderstorms to 
push through with the front. Rainfall amounts look to be around a 
tenth to a quarter inch. 


High pressure builds over the area with a much cooler airmass for 
Saturday. A strong jet streak then pushes over North Texas on Sunday. 
This could bring a brief chance of rain on Sunday but think most 
of the activity will be over North Texas into the arklatex. Return flow 
sets up quickly as another low deepens over the North Plains in 
response to another stronger trough. This system pushes east 
rather quickly with no frontal passage. By Wednesday next week another 
broad trough forms over The Rockies. Southern branch of the jet 
becomes more active and could support active weather for mainly 
North Texas. Moisture advection will again support at least some 
shower and thunderstorm activity for the area next week. 


39 


Marine... 
moderate onshore flow expected for the next couple days. Speeds 
might flirt with caution criteria at times - as early as tonight. 
Will forego caution flags at this time and just go west/ 15kt and let next 
shift reevaluate trends. Gradient weakens a bit early Friday in 
advance of the next cold front. Expect this boundary and 
associated thin line of rain showers/thunderstorms and rain to push off the coast late 
Friday evening. Small craft advisories will be required in its 
wake. Nearly winds will gradually veer back to the southeast early Sunday 
as high pressure moves off to the east. 47
