NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
342 am CDT Friday Aug 29 2014 


Discussion... 
more active weather pattern will be commencing today. An upper level 
trough is currently moving east across the Central Plains. In doing 
so...it has split ridging across the southern Continental U.S.. by doing 
so...the Gulf of Mexico will be opened up to the area through the 
weekend which will set the stage for higher rain chances. Latest 
water vapor imagery shows influx of moisture rich air just on the 
cusp of the coastal waters of County Warning Area. Showers and thunderstorms can be 
seen on radar along this edge of moisture. Have staggered hourly probability of precipitation 
to try to best time coverage increase throughout the morning and 
afternoon. Coverage should range from lower 40s in SW Mississippi to 
70 along the coast. 


Model soundings show abundant moisture...precipitation water over 2 
inches...will be in place through Saturday with a maximum on Saturday. 
Thus thinking coverage will be widespread and rainfall rates quite 
high. In addition...have increased probability of precipitation even more on Saturday from 
previous forecast of 70 to 80 percent for about 2/3's of the County Warning Area. This 
is above most guidance but not by much. Increased cloud cover and 
widespread convection should limit daily warming...so have kept 
highs only in the middle to upper 80s. 


Rain chances should start to come back down starting next week as 
the trough to the north races northeast and upper ridge builds back 
in across the southern half of the United States. More typical 
summertime daily afternoon thunderstorms will be possible. GFS and 
European model (ecmwf) still showing a weak tropical wave moving across the Yucatan 
Peninsula and into Mexico going into the middle of next week. Will 
be something to monitor although no tropical threat exists at this 
time. 


Meffer 
&& 


Aviation... 


There will a higher risk of showers and thunderstorms impacting the 
terminals today. Given this risk...have included a tempo group with 
ts wording and MVFR visibility restrictions from around 18z through 24z. 
Outside of the convective risk...VFR conditions should prevail at 
all of the terminals. 32 


&& 


Marine... 


A persistent ridge of high pressure extending across the eastern 
Gulf of Mexico will dominate the marine zones through the forecast 
period. Today into tomorrow...a weak tropical wave will move up 
from the central Gulf of Mexico. A slight increase in the pressure 
gradient should push winds into small craft exercise caution range 
over the offshore Gulf waters. As the tropical wave moves inland 
the gradient will weaken on Sunday. With the ridge still in 
place...southeast winds of 10 to 15 knots will be the rule from 
Sunday through Wednesday. Seas will generally range from 3 to 5 
feet through the end of the forecast period. 32
