NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
352 PM CDT Friday Jul 25 2014 


Short term... 
a rather flat pressure gradient over the region has winds varying 
from southwesterly around a high centered over the middle 
Gulf...to northwesterly in interior sections from Continental high 
pressure over upper Mississippi. There is a convergence zone of 
sorts over souteast Mississippi and north of the tidal lakes to 
aid focus for lake breeze convection this afternoon. With very 
little steering...most of the storms are running on propagation 
along the convergence band but becoming outflow dominated rather 
quickly. The few cluster of cells on the scope should dissipate by 
sunset this evening. With boundary layer decoupling 
overnight...may see some minor shallow fog developments by 
daybreak to burn off by mid-morning. Convective coverage on 
Saturday should remain below normal and focused on lake and Gulf 
Breeze boundaries. Coverage should once again be isolated and 
short-lived in nature. 


Long term... 
the main concerns will remain with the expectations of a cold 
front advancing southward as deep troughing takes place over the 
eastern United States. The front is still indicated by the models 
to move through accompanied by thunderstorms Monday night through 
Tuesday morning. It is still uncertain if the front will actually 
clear the coast before becoming stationary though convection may 
induce it southward initially before becoming quasi-stationary 
Tuesday into Wednesday. The presence of the frontolytic boundary 
will serve to either disrupt the land-Gulf Breeze cycle or 
enhance the Gulf Breeze aspect for synoptic scale augmentation of 
convergent low level winds. There is a bit of a timing 
disagreement between the GFS and European model (ecmwf)...but both models do 
indicate an impulse eventually running along the frontolytic 
boundary to increase rain coverage and efficiency middle of next 
week. The GFS is more ambitious with pushing the front well into 
the Gulf...while the European model (ecmwf) keeps it closer to the forecast 
area...thereby posing the greater risk for heavy rains next week. 
At this time...indicated a blended forecast that allows for 
adjustments upward next week but conceding the front may have a 
chance to reach farther south than currently believed. 


&& 


Aviation... 
have kept the mention of convection out of the forecast for the 
afternoon hours today and tomorrow as coverage is isolated at 
best. A scattered to broken cumulus field running around 4000 feet will 
linger through 00z...but should dissipate shortly after sunset. 
There may be some light fog formation at several of the terminals 
around 10z to 13z...which could produce a period of MVFR 
visibility restrictions. This fog should quickly clear once the 
weak low level inversion lifts. Overall...expecting to see VFR 
conditions prevail at all of the terminals. 32 


&& 


Marine... 
light to moderate southwest winds around the northern periphery of 
high pressure centered over the middle Gulf is expected to prevail 
through Sunday. Cold front moving from the north remains to be 
seen if it will actually move south of the outer coastal waters 
Tuesday or early Wednesday. At this time...forecast will reflect 
it moving into the coastal waters and becoming stationary...which 
would increase the risk of storminess in the marine areas next 
week.
