NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
838 am CDT Sat Jul 4 2015 


..sounding discussion... 


The sounding this morning measures plenty of instability with 
mixed layer cape at 2700 j/kg... mu cape 3600 j/kg. Middle level 
lapse rates are relatively steep at about 6.8 c/km and 500 mb 
temperature is -10 c. The environment is favorable for storms with 
enough forcing... which we will see first from some moisture 
convergence and advection off the Gulf just to the west of our County Warning Area. 
Indeed winds are southwesterly from the surface to 500 mb then 
northwest above. Later today the outflow boundary will continue 
southward from storms currently across north la and central MS... 
which will likely affect our SW MS counties. The 12z sounding 
from Shreveport sampled the favorable shear and storm maintance 
environment just ahead of the line. A bit of a moisture axis is 
sampled by the Lake Charles sounding with precipitable water at 1.99 inches... at 
lix the precipitable water is near average at 1.73 inches.

Previous discussion... /issued 359 am CDT Sat Jul 4 2015/ 


Short term... 
a stationary front across OK/AR/TN will slowly move south and 
become defuse north of our area. Several shortwaves moving 
along the front will enhance precipitation chances this weekend. 
An area of low pressure at the base of the shortwave will be 
located in Arkansas today at 18z and on the Tennessee/Kentucky line at 18z sun. An 
enhanced area of 1000-500mb relative humidity values move through the flow over 
the next few days. Precipitable water at 00z sounding was 1.78 in with an Li 
around -9. Not much in the way of speed or directional shear 
however plenty of parcel instability. Hrrr forecasts some rain showers 
development beginning around 15z becoming quite widespread during 
the afternoon as a line of thunderstorms and rain moves across the area. Some of the 
rain showers/thunderstorms and rain activity could last into the evening hours. Storm Prediction Center day 1 
outlook has a marginal risk of severe weather today as the area of 
convection moves in from the west. Any interaction with sea and 
lake breezes plus outflow boundaries could enhance some of the 
thunderstorms and rain activity resulting in frequent lightning... strong gusty 
winds...and heavy rain. There could be a few storms which reach 
severe criteria which could have an impact on Fourth of July 
outdoor activities. Temperatures will remain warm however cooler 
near areas of rain today and Sunday. 


Long term... 
a ridge of high pressure centered over the North Texas/OK border will 
build by middle week. A few impulses will bring a few rain showers/thunderstorms and rain to 
the area however probability of precipitation will be will low. A weak tropical wave moves 
west across the Gulf next weekend with little impact outside of 
a few showers in the coastal waters. With the high pressure will 
come warmer temperatures with highs from the low to middle 90s. 


Aviation... 
VFR conditions will develop once again this morning with towering 
cumulus being noted at all sites. Scattered sh/ts are expected today 
with the most coverage being mainly this afternoon. Ts development 
should begin during the morning hours and spread over btr and mcb 
sites initially. A few showers may affect the southshore 
terminals by late morning. No activity expected during the morning 
for coastal miss. Ts coverage will increase through the day and 
should affect all sites before the end of the 12z taf period. 


Marine... 
Bermuda ridge pattern to maintain light southerly flow for the 
forecast period. Thunderstorms developing ahead of as well as along 
a squall line will bring the threat of high winds and waves over the 
tidal lakes this afternoon and evening. Several of these may be 
strong or even severe late today. The amount of marine traffic will 
be higher than usual this Holiday weekend...please be alert for any 
special marine warnings that may be issued. Otherwise...light winds 
and low seas expected through Tuesday night. 


Decision support... 
dss code....blue. 
Deployed...none. 
Activation...none. 
Activities...river flood warnings on Mississippi River from Red 
River Landing to Baton Rouge.
