NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
341 am CDT Thursday Sep 18 2014 


Short term... 
forecast for today will be highly contingent on upper level 
impulse energy currently over Texas that is anticipated to expand 
eastward by this afternoon. Northwest flow was prevalent above 
20kft with a vorticity shear zone noted in wind data and emulated 
in broader radar presentation across Texas. The complex currently 
over the Austin area should continue to move southward along maximum 
Theta-E axis. GFS...NAM and European model (ecmwf) are in fairly good agreement in 
indicating a vorticity structure and strong Omega moving into the 
area but do have some variations on timing. The GFS is earliest 
with a 17z-18z onset in the forecast area...the European model (ecmwf) about middle- 
afternoon peak onset and NAM late afternoon with more emphasis on 
nocturnal convection than the other two. Have opted to go closer 
to GFS timing given current trends. Despite all this...probability of precipitation will 
still be indicated on the lower side...20-30 percent for eastern 
2/3 of County Warning Area...trending to 50 percent adjacent to weather forecast office lch area where 
the greater focus should remain. This is a decent blend with 
neighboring offices. Did indicate somewhat higher than typical 
probability of precipitation for this evening as activity may linger longer before moving 
off the coast after midnight. This situation should also serve as 
a frontogenetic process that flushes the region of deep moisture 
for Friday...which looks now to be a dry day over land areas. 


Long term... 
Saturday and Sunday will be indicated to be drier than climatology with 
only 20 percent indicated for the afternoon Gulf Breeze 
considerations. Stronger cold front moves steadily through the 
area Monday with some attendant moisture worthy of 30 percent probability of precipitation 
pre-frontal. Drier Continental air then moves into the area for 
Tuesday through at least Wednesday before the front returns slowly 
northward next Thursday. Temperatures should only be affected to 
the cool side by a couple of degrees but greater influences will 
be on humidity levels for next week. 24/rr 


&& 


Aviation... 
some patchy fog is developing early this morning. Have included a 
mention of MVFR visibility restrictions from around 10z through 13z 
at most of the terminals. Some increased mixing of the boundary 
layer at kmsy...knew...and kgpt should keep reduced visibilities at 
Bay at these terminals. Khum will see the lowest 
visibilities...with a period of IFR restirctions possible early this 
morning. Once the low level inversion mixes out around 14z...a 
scattered to broken cumulus field ranging from 2500 to 3500 feet will 
become established. An upper level vorticity lobe will also move into 
the area. This could spark off some afternoon convection...and have 
included some probability 30 groups with ts wording to reflect this risk. 
Brief periods of MVFR and possibly IFR visibility restrictions and 
gusty winds can be expected with any convective activity. By 02z 
tonight...the convection should dissipate and a return to VFR 
conditions is expected. 32 


&& 


Marine... 
light easterly flow of 5 to 10 knots and seas of 1 to 2 feet will be 
found over the waters today. Gradient flow will increase beginning 
tomorrow with a period of exercise caution conditions expected over 
the Gulf coastal waters beginning tomorrow night and persisting 
through Saturday. This increased easterly flow will be in response 
to a weak low pressure system moving off the Texas coast and then 
pushing eastward across the central Gulf toward Florida. With 
stronger winds in place...seas will correspondingly rise to around 3 
to 5 feet on Friday and then further increase to 4 to 6 feet for 
Saturday. Some higher than normal tides will also be possible by 
Saturday given the persistent strong onshore flow. Tides will be 
most elevated along east facing shores. As the low pulls east of the 
area...the gradient will relax through the day on Sunday...with a 
return to lighter easterly flow of 5 to 10 knots for Monday. Seas 
will also fall back to 2 to 3 feet by Monday. These conditions will 
persist through Tuesday. 32
