NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
822 PM CDT Sat Jul 4 2015 




Sounding discussion... 
we have quite a moist atmosphere in place over the local area. 
Thats easy to see just by looking at the sounding which shows very 
low dewpoint depressions throughout the column with a maximum of only 
about 20 degrees f in the middle levels. This all equates to nearly 2 
inches for precipitation water. In terms of where this stands compared to 
normal per spc's sounding climatology Page...this time of year should 
be about 1.75" and the 75th percentile is 1.93". The result of 
these conditions will be very efficient rain producing cells 
throughout the night. Maximum low/middle level jet is about 35 knots. So 
could see gusts to 40 miles per hour or slightly higher with precipitation loading.

Previous discussion... /issued 337 PM CDT Sat Jul 4 2015/ 


Short term... 
weak short wave moving through the base of the broad middle level 
trough over the middle south region has enhanced convection across 
south Louisiana and south Mississippi today. Synoptic scale front 
remains north of the forecast area...organized scattered to 
numerous convection likely to linger to well into the evening and 
sag slowly slowly south before diminishing some after midnight. 
Strong to locally severe thunderstorm threat should continue 
through the evening hours as arms remains unstable until sunset. 
With middle level trough still lingering over the area Sunday...kept 
showers and thunderstorm chances in the 50 to 60 percent range on 
Sunday...with another early start to convection likely. 


Long term... 
middle level trough should start lifting out Sunday night and 
Monday...with middle level ridging building over the area through middle 
week. Broad middle level ridge from the SW North Atlantic into the 
northern Gulf Coast dominates the weather regime from middle week to 
the weekend. This should effectively keep temperatures slightly 
above normal...90 to 95 range...and only isolated afternoon 
thunderstorms. 


Aviation... 
generally VFR conditions outside of convection. Scattered to 
numerous showers and thunderstorms through 04z lowering ceiling and 
visible to IFR conditions and gusty winds to 35 knots in the stronger 
thunderstorms. Expect convection to become more scattered in 
coverage after 04z but continue through overnight hours. 


Marine... 
Bermuda ridge extending into the northern Gulf Coast will maintain 
a light southerly flow for the forecast period with winds 
less than 15 knots through the period. Scattered to locally 
numerous thunderstorms tonight and Sunday will become isolated in 
coverage by middle week. 


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


Decision support services (dss) code legend 
green = no weather impacts that require action 
blue = long fused watch/warning/advisory in effect or high 
visibility event 
yellow = heightened impacts with short fused watch/warning/advisory 
issuances; radar support 
Orange = high impacts - slight to moderate risk severe; nearby 
tropical events; hazmat or other large episodes 
red = full engagement for moderate risk severe and/or direct 
tropical threats; events of National significance
