NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1216 PM CDT Friday Jul 31 2015 


Update... 


Updated forecast and grids to lower rain chances across southern 
half of area to 20 percent...and hrrr would indicate that may be a 
little high. Adjusted hourly temperatures and dew points to fit 
current trends. 


&& 


Previous discussion... /issued 415 am CDT Friday Jul 31 2015/ 


Short term... 
the heat will be on for a short time today. But a cold front just 
to the north of the area will slowly move through today. Dew points 
will begin to lower in mcb by sunrise and should reach about 63 
degrees by afternoon. Deep temperatures will lower in Slidell around noon 
and to the South Shore shortly after. This contrast to the deep 
temperatures that we have been under lately will be felt. This will also 
do two things. One will be to keep temperatures near what they have been 
or even slightly higher. The second thing will be to keep the heat 
index values down. Timing of sh/ts have been off the last few days 
and that always has a major impact on temperatures and therefore heat 
index values. But today should not be a timing issue as dry air 
will be the cause of lower heat indices. The front will move back 
to the north by Sat night bringing back the moisture and higher 
heat index values. The front should also keep all sh/ts activity 
along and south of it so pop gradients have been set accordingly. 


Long term... 
sh/ts will once again be back to the area once the cold front 
lifts north over the weekend. After the weekend...most sh/ts will 
be activated by sea breeze and outflow boundaries. 


Aviation... 


VFR conditions are expected with the main exception at khum where 
some tempo MVFR will continue this morning due to light fog. 
Maintain thunderstorms in the vicinity this afternoon for the airports closer to the coast 
where there is a better chance of convection. 18 


Marine... 


A cold front is expected to push south across the tidal 
and extreme near shore waters today and stall. A slight decrease in 
thickness 1000-700mb show a 10 to 15 meter drop today. North winds 
will kick up to 10 to 15 knots across near shore waters this morning 
and again Saturday morning. The stalled cold front over the coastal 
waters will begin to lose its identity over the weekend. High 
pressure will build over the East Gulf and yield a westerly flow 
over the north central Gulf early next week. 18 




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