NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
906 am CDT Monday Jul 28 2014 


..sounding discussion... 
A fairly moist column up to 700mb with the exception of a bit of 
drying around the 950mb level on this morning/S sounding. Other 
notable features are the dry air above 700mb which could mix down 
in afternoon thunderstorms and produce strong to severe wind 
gusts. This is supported with downdraft cape values around 950 
j/kg. Precipitable water values of 1.90 mean that locally heavy 
rain is possible. There is also a warm temperature layer from 
700mb to about 650mb. As for instability...there is a good amount 
with MLCAPE values calculated around 1400 j/kg. While there is 
cape in the 0 to -20c hail growth zone...there is not much 
moisture there so hail threat seems quite low. The freezing level 
is around 17000 feet. Winds were from the west up to 700mb and 
then light in the middle levels and then from the north in the upper 
levels. The maximum wind speed of 26 knots was located at about 
1000 feet above the ground. Stats on this morning/S successful 
balloon launch are that it burst over Lake Pontchartrain at a 
height of 20.7 miles above the ground.

Previous discussion... /issued 426 am CDT Monday Jul 28 2014/ 


Short term... 
a quiet overnight period with only a few clouds around early this 
morning. A cold front is just off to the north making its way into 
north central Mississippi and southern Arkansas. This front will 
be the main player in the forecast this week. Over the last hour 
or so storms have developed over southern Arkansas. Mesoscale 
models have shown this to be the case over the last few runs...and 
going off of that the trend is for thunderstorms to continue to 
develop as the front sags southward. If this is the case we should 
expect scattered showers and thunderstorms this afternoon across 
the entire forecast area. The atmosphere is conducive for 
thunderstorms as the atmosphere is unstable...we have a lifting 
mechanism in the front...and we have plenty of moisture around as 
precipitable water values are expected to be in the 1.90 to 2.10 
range this afternoon. All of the ingredients are the basics for 
thunderstorm development. Some of these storms this afternoon 
could be on the strong to severe side and with that the Storm 
Prediction Center still maintains a slight risk of severe weather 
mainly across the Mississippi Gulf coastal counties into portions 
of St. Tammany Parish. These thunderstorms could produce strong 
damaging wind gusts...frequent lightning strikes...hail...and 
locally heavy downpours. The front will continue to push through 
the area through tonight. 13/mh 


Long term... 
the front should make it completely through the forecast area and 
should clear the coastal waters before stalling. Models still 
insist on keeping boundary in the northern portions of the Gulf 
before drawing northward towards the end of the week. An upper 
impulse ejects from the west that will likely induce a wave upon 
the surface front over East Texas to rapidly destabilize the 
region Thursday and Friday. So Wednesday and early Thursday should 
be a dry period prior to returning to a wet pattern late Thursday 
into the weekend. 13/mh 


Aviation... 
thunderstorm coverage will be a little more today and each terminal 
should be visited by a few or at least nearby. Scattered to broken 
ceilings will move from around 020 up to 050 by this evening. 


Marine... 
an approaching upper level trough and associated cold front will 
keep winds generally south to southwest with speeds ranging mainly 
from around 8-16 knots and seas around 3 feet as a weak but unusual 
summertime cold front approaches the coastal waters early Tuesday. 
Northeast winds will eventually develop early Wednesday but the 
front will quickly lose its integrity as it moves farther out into 
the Gulf of Mexico. A weak pressure pattern will keep winds light 
and more variable the remainder of the forecast period.
