NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
349 am CDT Thursday Oct 23 2014 


Discussion... 
high pressure will remain in control of the area/S weather through 
the end of the week with cool and dry conditions persisting. 
Overnight lows will continue to be below normal next few nights 
north of the lake and near normal south of the lake. Afternoon 
highs should be seasonable...in the middle 70s...today. 


Upper ridging will build into the area from the west Friday 
through the weekend...resulting in a warming trend through the 
first part of next week. Subsidence aloft and a dry air mass will 
keep rain chances negligible through at least Tuesday. 


Some uncertainty in the forecast going into the middle of next 
week...but models generally agree that a slow return of moisture 
will begin late Sunday/Monday as the surface high finally slides 
east of the local area and winds become onshore again. Euro has 
slowed progression of the next front and is more in line with the 
GFS timing from last night/S 00z run. Now looks like the frontal 
passage will hold off until late Thursday or Friday. Also of note 
is that there is some disagreement concerning the strength of the 
front as well...with the GFS now showing a cleaner/stronger 
frontal passage than the Euro...a fairly significant change 
compared to last night/S model runs. Luckily the largest 
differences remain just outside the current forecast period...so a 
blend of available guidance still seems reasonable in the extended 
portion of the forecast. 


&& 


Aviation... 
VFR conditions will prevail for the next couple days and beyond. A 
band of high level clouds with bases 150-250 will move through with 
an upper disturbance this afternoon and evening. Northeast winds 
will be a bit stronger in the 10 to 15 knots range at knew and kmsy 
this morning...otherwise north to northeast winds will be 10 knots 
or less. 


&& 


Marine... 
a brief period of small craft exercise caution conditions will 
continue over the open Gulf waters through 7 am. These conditions 
may slowly abate today as the cold air advection relaxes. 
Northeasterly winds around 10 knots will continue through early next 
week...with the possible exception of a brief increase to around 15 
knots late Saturday or Sunday as high pressure to the northeast gets 
re-enforced. 


The surface high over the Gulf south will become more centered over 
the eastern Seaboard by Monday...allowing winds to shift to a more 
easterly and then southeasterly direction. The pressure gradient 
over the area will also weaken during this period and expect winds 
to fall to around 10 knots or less. Seas will also fall to 2 feet 
or less on Monday. 


&& 


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