NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
229 am CDT Tuesday Oct 21 2014 


Discussion... 
this will be pretty short and Sweet since there/S not a whole lot 
to discuss. Once again generally only minor tweaks made to the 
forecast as model guidance remains in good agreement and forecast 
thinking hasn/T changed. 


A persistent low/trough over the East Coast will reinforce cool 
and dry high pressure over the local area with a dry cold front 
forecast to move through the area late Tuesday/early Wednesday. 
This will keep temperatures pleasant through at least Thursday 
with highs ranging from the middle 70s to lower 80s and the lows 
generally ranging from the upper 40s to the middle/upper 50s most 
locations. 


By Friday...the low/trough over the East Coast will lift 
northeastward...allowing the surface high to also shift eastward. 
This will result in some very gradual modification to the airmass 
over the weekend with a slow warming trend continuing into early 
next week. Next front looks to hold off until middle week next 
week...but this is beyond the current forecast period and there 
are some significant differences in the models beyond about 
Monday. 


&& 


Aviation... 
VFR conditions are expected at area terminals through the forecast 
period as a dry and stable airmass remains over the region. 


&& 


Marine... 
a reinforcing front will bring another surge of cooler and drier air 
into the region today. A brief period of small craft exercise 
caution conditions will be possible over the Gulf waters beginning 
tonight and persisting through Thursday. North-northeast flow of 15 
to 20 knots and seas of up to 5 feet are expected during this 
period. The gradient flow will begin to ease by Friday...allowing 
the northeast flow to drop to between 10 and 15 knots. Seas will 
also fall back to 3 feet or less during this period. These 
conditions will persist through the weekend as high pressure over 
the Gulf south interacts with a region of lower pressure over the 
southeastern Gulf of Mexico. 


&& 


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