NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1213 PM CST sun Nov 23 2014 


Aviation... 
rain has ended at all the taf airports...so the main impact in the 
first 6 hours will be lingering MVFR ceilings and gusty southwest 
winds. These clouds are expected to scatter or clear out 20z-22z. 
Another round of low stratus and possibly some fog should develop 
this evening and overnight and produce IFR/LIFR conditions near 
khum...kasd...and kgpt. Cannot rule out at least low IFR ceilings at 
kmsy and knew...but confidence is a bit lower so have left out the 
lower conditions for now. Any lingering clouds and fog should 
quickly clear out around daybreak or shortly thereafter on Monday 
as drier air surges in behind a cold front. 22/dew point 


&& 


Previous discussion... /issued 350 am CST sun Nov 23 2014/ 


Short term... 
all eyes this morning will be on a strong system moving across the 
lower Mississippi Valley this morning. This system has triggered an 
impressive squall line that is currently moving east-northeast this morning 
just along the Louisiana coast this morning. This will impact our 
area this morning as the Storm Prediction Center still maintains a 
slight risk of severe weather for portions of our forecast area 
this morning. In fact there may be a watch posted at some point 
this morning however there are a still a few factors that may keep 
the threat at Bay. A sounding at 6z showed a deep marine layer 
over 3500 feet in depth over the area. This is a stable cool layer 
in the atmosphere and would prohibit surface based convection. 
That means that the strong damaging winds that would accompany the 
storms would not be able to mix down to the surface and cause 
damage. Also the instability and Richer dewpoints have stayed off 
the coast and is having a very hard time getting inland and this 
again would keep the strong convection just along the coast and 
out over the Gulf. 


Overall the main threat from a severe weather standpoint should 
remain along and south of Lake Pontchartrain this morning...this 
is not to say that any other areas could not get severe weather 
but the threat looks to be south of Lake Pontchartrain. There have 
been a few small storms beginning to develop ahead of the main 
line and these storms will definitely have to be watched closely. 
As far as threats go...we still anticipate damaging wind gusts 
along the leading edge of the line and still with strong 
helicity...some embedded rotating cells will be possible this 
morning. The majority of the forecast area will see a heavy rain 
as this system moves through. Still expect 1 to 3 inches of 
rainfall this morning as this system moves through. Stay weather 
aware this morning by monitoring our social media pages and our 
web Page for the latest information. 13/mh 


Long term... 
the front does not push through until later on tonight into Monday 
morning. Cooler and drier air will move in behind the front...but 
air mass behind the front is not nearly as cold as the last two 
fronts. High pressure stays firmly in place through most of this 
upcoming week. Have not made many changes to forecast from 
previous package. 13/mh 


Aviation... 
widespread IFR and even some areas of LIFR ceilings will be 
observed through the early to middle morning hours. Showers will be 
increasing across the forecast area between 10z and 12z with a 
potential squall line moving from west to east across the area 
after 12z. Clearing skies will spread in from the west during the 
afternoon Sunday with a return to VFR conditions at all of the 
terminals 


Marine... 
a squall line is currently moving across the coastal waters this 
morning. Windy conditions will prevail and high winds are expected 
to accompany the squall line this morning. Expect special marine 
warnings and some waterspouts will be possible as the line sweeps 
through. Small craft advisories are still up and will be up 
through at least this evening. The cold front will finally move 
through Monday and as this happens winds will get another surge 
back into scy criteria. Moderate to strong offshore will remain 
over the region Tuesday through much of next week. 13/mh
