NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
818 am CDT Thursday Jul 31 2014 


..sounding discussion... 


Moisture has begun to return to the central Gulf Coast this 
morning. It is primarily in the middle-levels where the moisture has 
returned as below 700mb remains fairly dry still. 
Nonetheless...precipitable water values have in turn responded 
going up about half an inch from last evening to 1.58 inches. 
There are a few temperature inversions on this morning/S sounding. 
The first is the typical...summertime inversion near the 
surface...which is fairly Stout. While the second inversion located 
between 850mb and 825mb is weaker...it may limit the coverage of 
any thunderstorms that are trying to arrive from the northwest 
from the arklatex region. Not expecting anything severe as 
convective parameters on this morning/S sounding show a stable 
atmosphere...with SBCAPE and MLCAPE at 0 j/kg and a positive 
lifted index. Winds at the surface are calm or light from the 
southeast up to about 900mb and above this level primarily from 
the northwest. The balloon/S flight this morning ended over the 
eastern part of Lake Pontchartrain at a height of 21.4 miles above 
the ground.

Previous discussion... /issued 416 am CDT Thursday Jul 31 2014/ 


Short term... 
business will begin to pick up across the southeast today and 
heading into the weekend. A shortwave is currently diving 
southward and has triggered an area of showers and a few 
thunderstorms across Arkansas and northeast Texas. Looking at the 
radar presentation of this is looks like convection is having a 
hard time sustaining itself with the exception of some deeper 
convection closer to The Heart of the shortwave energy. Expect 
convection to continue to have a hard time today as forecast 
soundings across the area still suggest a small inversion over the 
forecast area. This is another obstacle that could prohibit convection 
today. However the shortwave moving across should be enough to 
provide for some showers to develop later on today. Will maintain 
a 20 to 30 percent chance of showers and thunderstorms today. 
Moisture will continue to increase today as precipitable water 
values continue to climb and reach the 1.8 to 2.0 inch range by 
tomorrow. This should set the stage for a wet period over the weekend 
into early next week. 


The wave and associated boundary will be over the area Friday 
through the weekend and will be the focus for shower and thunderstorm 
development. Any rainfall could be potentially heavy due to the 
slow storm motions of around 5 knots expected. The air mass will 
change little going into Saturday...and expect another round of 
convection to develop in the vicinity of the front. 13/mh 


Long term... 
going into the weekend the air mass really does not change expect a 
good chance of showers and thunderstorms as that boundary remains 
in the area. Not much change in thinking from previous forecast. Ample 
moisture will still be in place...with model soundings showing precipitable water 
values still around 2 inches...slow storm motions of 5 knots or 
less. Again this means any convection will have the potential to 
drop heavy rainfall over isolated areas. This could continue to 
keep a localized street flooding threat in place over the area. 
Once again...the convective threat will be greatest during the 
afternoon hours when overall instability is highest. The trough 
will slowly break down early next week as the air mass loses some 
of its juice. However still expect diurnally driven convection 
each afternoon. 13/mh 


Aviation... 
VFR conditions to prevail at all terminals despite steadily 
increasing moisture and high cloud cover from disturbance moving out 
of the arklatex. There will be 30 percent chance of mainly showers 
this afternoon to warrant a prob30 mention but thunderstorms may be 
more isolated in coverage next 24 hours. 24/rr 


Marine... 
light winds and low seas are expected to prevail through the next 5 
days. The coastal waters undergo transition to a more typical 
land/sea breeze regime in coming days as a weak pressure field 
remains in place across the north Gulf. 24/rr 


Decision support...

Deployed...none.
