NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
406 am CDT Sat Aug 23 2014 


Short term... 
only real issue for today will be warm temperatures and heat index 
values in the 105-110 range most locations this afternoon. Per 
local guidance and policy of utilizing the synoptic health watch- 
warning network...which accounts for cumulative effect of 
excessive heat...today will make day one of a moist tropical+ 
/mt+/ air mass. Sunday's temperatures will be indicated to be a 
degree or two warmer than today and also make day two of mt+ 
conditions...worthy of an excessive heat watch. The models are 
suggesting...for various reasons...some nocturnal rainfall moving 
from the east into the forecast area Sunday night that would 
effectively end the string of mt+ conditions. The NAM is 
indicating a well estabished easterly wave that may actually be an 
emanation of energy from invest 96l...the GFS is showing an impulse 
rounding the fringe of the ridge from Alabama...through coastal 
Mississippi into eastern la prior to sunrise. The European model (ecmwf) is less 
ambitious with the rain coverage...confined mainly over Jackson Colorado 
MS. Have opted to go closer to GFS idea of impulse driven 
convection developed in high Theta-E air with plenty of outgoing 
longwave radiation to work with late evening and overnight Sunday 
night. 


Long term... 
the center of the high is expected to become oriented along the 
eastern Seaboard and extending into the Gulf states for a period 
of deep easterly flow Tuesday...possibly tainted by some fringe 
moisture tapped from invest 96l or eventual tropical system east 
of the U.S. Coast. Otherwise...typical temperatures and rain 
chances expected Tuesday through Friday. 24/rr 


&& 


Aviation... 
expect VFR conditions to continue through the forecast period. There 
has been some light patchy fog this morning in a few spots but 
widespread fog is not expected. Convective chances rather 
small...have elected not to mention thunderstorms in the vicinity in this issuance since the 
coverage yesterday was so limited. 13/mh 


&& 


Marine... 
high pressure remains in place over the coastal waters. This high 
will remain in place through the weekend. Seabreeze/landbreeze cycle 
will dominate. Expect offshore winds in the morning hours and 
onshore winds developing during the afternoon hours. Winds and seas 
should remain fairly benign. Winds will generally be 10 knots or 
less and seas will generally be 2 feet or less. Winds will take on a 
more persistent easterly flow early next week as the surface high 
becomes centered north of the region. East winds of 10 to 20 knots 
and seas of 3 to 5 feet can be expected late Monday night through 
the middle of next week. 13/mh 


&& 


Decision support... 
dss code...green. 
Deployed...none. 
Activation...none. 
Activities...slurry support.
