NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1232 PM CDT Thursday Apr 24 2014 


Aviation... 
generally VFR conditions will prevail through sunset with the 
exception of a few low clouds lingering at btr and hum. After 
sunset...expect ceilings to lower again...with IFR conditions setting 
in at nearly all terminals by about 8z. Conditions will improve 
again after sunrise. 


&& 


Previous discussion... /issued 1014 am CDT Thursday Apr 24 2014/ 


Update... 
sending new zones to remove morning fog wording...otherwise no 
changes at this time. 


Sounding discussion... 
no problems with flight this morning. Very dry profile throughout 
with just a very shallow surface inversion. Precipitable water 
0.75 inches. Lifted index -3.2. Winds southeast-SW 10-20kt surface to a 
calm level at 9600 feet...NW-SW 10-70kt above with peak wind 
255/68kt at 47.2kft. 


Previous discussion... /issued 342 am CDT Thursday Apr 24 2014/ 


Short term...it has been quiet overnight with only very patchy fog 
developing by 8z. Main concerns through the short term portion of 
the forecast are on the very weak frontal boundary dropping in here late 
tonight/tomorrow. 


Today will be very much like yesterday with mainly some cumulus 
developing as a weak seabreeze tries to develop. The main antagonist 
in the next 24/48hrs is a short wave currently moving through the southern 
portions of the southern rockies. As it moves into southern and Central Plains 
today it will drive a surface low into the middle MS valley by this evening 
with a cold front draped back to the SW into the arklatex. The surface 
low will then become stacked with the short wave as they both move into the 
Ohio Valley region Friday. The flow over our area will remain mostly 
zonal. With that the cold front will begin to lose some momentum but 
will still slowly sink into the County Warning Area early Friday morning and twrds the 
coast Friday afternoon. There may be a few light rain showers/thunderstorms and rain associated with the 
front early Friday but overall rain chances look fairly low. Hghts will 
rise through the day Friday and there will be little if any ll 
convergence to work with as high pressure pushes down into the 
region. 


Heading into Friday night and Sat...even though the front will struggle 
to get to the coast much drier air will push into the area with 
dewpoints dropping into the 50s. This will combine with light winds 
and mostly clear skies leading to a pleasantly cool night. This will 
be short lived as return flow will quickly set back up during the 
day Saturday leading to dewpoints quickly climbing into the middle to 
upper 60s. /Cab/ 


Long term...the forecast begins to get more active during the first 
half of the work week. Models continue to indicate a severe weather 
outbreak across much of the central Continental U.S. And MS valley sun through 
Monday night. 


The main issue during the first half of the long term portion of the 
forecast has not even moved onshore yet. The l/west trough will move over 
the Pacific coast Friday with a strong disturbance dropping down the back 
side of the trough and moving into California Friday night. This disturbance 
will move over the Continental Divide Sat night and deepen as it 
approaches the plains sun. The potent disturbance will continue to 
work east twrds the MS valley late Monday night. It will likely 
generate multiple rounds of severe weather sun through Monday night but 
the question is will it reach this far south. Rain chances will 
increase Monday and through Monday night and if we have severe weather it 
appears the best chance for that will be Monday afternoon and Monday night. 
This is still 5 days out so will keep from getting into too much of 
the details but there will be ample instability to work with even 
though the majority of the forcing will stay just north of the 
region there should be enough to get convection into the region. All 
modes of severe weather appear possible at this time but again the 
bulk of the severe weather will likely remain north of the County Warning Area. 


Our large cyclone over the central Continental U.S. Will be very slow to push 
east and will begin to dominate much of the eastern Continental U.S. Thus driving 
cooler and drier conditions into the region around Wednesday and through 
the remainder of the week and into the weekend. /Cab/ 


Marine...fairly benign conditions expected over the coastal waters 
from now through middle weekend. High pressure currently centered over 
the central Gulf of Mexico will gradually shift eastward. Southerly 
winds will generally be around 10 knots with seas 2 feet or less. A 
northern stream trough will bring a weak front to the Gulf Coast 
Friday. At this time...it appears this front will be to weak to really even 
make it into the coastal waters. Going into Sunday and beyond the 
winds/seas will increase as the pressure gradient tightens due to 
surface low developing in the Southern Plains. Exercise caution 
conditions could exist as early as Sunday and persist through Monday 
night borderline small craft winds possible. Models indicate that a 
cold front will swing through Tuesday night with a reinforcing 
boundary Wednesday night. /Meffer/
