NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
342 am CDT Friday Sep 19 2014 


Short term... 
vorticity shear zone situated across the forecast area is running 
its course this morning with some frontogenetic processes 
underway. Drier Continental air is expected to slowly filter 
southward throughout the day for a drier day for much of the area. 
The exception will be areas south of the tidal lakes where low 
level moisture convergence may become enhanced on lake breeze. 
Will maintain 30 percent rain chances for that area through 00z 
but drying out steadily in the evening. Saturday and Sunday should 
also be unseasonably drier over land areas. Temperatures should 
remain a few degrees above normal. 


Long term... 
models continue to remain in consensus with frontal passage for 
Monday though they appear to be less pronounced with rainfall 
along the frontal zone as low level moisture diverges with its 
passage. Have lowered probability of precipitation a bit for Monday then maintaining a dry 
forecast for Tuesday and Wednesday. An easterly wave is then 
expected to move along the southern periphery of the Continental 
high to bring a slightly better chance of rain Thursday...but only 
worthy of 20-30 percent at this time. Temperatures should remain a 
few degrees above normal with a slow trend towards normals by 
middle of next week. 24/rr 


&& 


Aviation... 
an extensive middle-level cloud deck remains over the area...and some 
light precipitation continues to affect the more coastal terminals 
such as khum...kmsy...and kgpt. There may be some fog and low 
ceiling formation at kmcb...khdc...kbtr...kasd where a weak low 
level inversion may develop before 12z this morning. The inversion 
should quickly mix out by 14z...with a return to VFR conditions 
expected. The cloud deck should linger through around 18z as an 
upper level disturbance continues to move through the area. As the 
disturbance pulls to the east and some drier air begins to filter in 
aloft...the cloud deck will rise above 12k feet and also begin to 
break up between 18z and 00z. Another weak inversion may develop 
after 10z...which may lead some patchy fog formation at kmcb and 
khum. At most...a period of MVFR restrictions may develop with this 
fog. 32 


&& 


Marine... 
a broad area of low pressure will move through the Gulf of Mexico 
from Texas toward Florida over the weekend. This area of low 
pressure will lead to an increase in the pressure gradient and 
resultant gradient flow across the coastal waters through Saturday 
night. The gradient should maximize tonight and tomorrow...with 
easterly flow of 15 to 20 knots expected over the open Gulf waters 
east of the Mississippi River. Seas will also rise to around 4 to 6 
feet in the outer Gulf waters with 2 to 4 feet seas in the sounds 
possible. Given these conditions...expect to see small craft 
exercise caution flags posted for the Gulf coastal waters and 
possibly the chandeleur and Breton sounds for tonight and tomorrow. 
This low will pull to the east by Sunday...allowing the pressure 
gradient to decrease somewhat for Sunday and Monday. Expect to see 
easterly flow of around 10 knots and seas dropping to 2 to 3 feet 
during this period. A cold front will then pass through the marine 
zones Tuesday into Tuesday night. As some drier air advects over 
the area...a brief increase in winds back toward exercise caution 
range will be possible. 32
