NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
343 PM CDT Wednesday Jul 29 2015 


Discussion... scattered showers and thunderstorms have developed 
and are tracking southwest across the forecast area. Fast movement 
and generally smaller storms not going to pose a flash flood 
concern. However... storms under northeast flow typically have 
better chance to produce strong down bursts. So will have to monitor 
for that threat. Some of the convection will dissipate with loss of 
daytime heating but will still have some lingering convection this 
evening...mainly eastern 1/3rd of the County Warning Area. Weak surface trough 
elongated across the southeastern Continental U.S. And northern Gulf Coast will 
keep the chance for rain overnight with best probabilities east of a 
Slidell to New Orleans line although majority will be offshore. 


An upper ridge currently centered over northern Texas and Oklahoma 
is in the process of retrograding west and will remain over the 4- 
corners region through the weekend. At the same time...an upper level 
trough is dipping out of Canada and will gradually dig southeast 
across the eastern half of the country. The aforementioned surface 
trough will be the focus for convection Thursday and have thus 
increased probability of precipitation into the 40 to 60 percent range. This coverage should 
be high enough to keep highs from reaching upper 90s and heat 
indices from making it to heat advisory values. Enhancement of 
rainfall coverage is expected as a weak frontal boundary moves in 
from the northwest Friday but mainly in the southern half of the 
County Warning Area...south of Interstate 12. Strengthening of the ridge to the west 
will gradually push the trough to further south and east which will 
lower County Warning Area rain chances. 


Meffer && 


Aviation... overall VFR conditions will continue. Only issue would 
be if convection impacts any of the terminals this afternoon or this 
evening. /Cab/ 


&& 


Marine... the winds across the coastal waters are generally 
expected to vary from southwest to northwest in direction through 
the end of the week and be light to occasionally moderate in 
magnitude. Seas will be 3 feet or less. A broad surface low draped 
across the northeast Gulf and northern Florida will draw winds into 
it which will result in nwrly winds over the coastal waters. Have 
also increased wind forecast for Lake Pontchartrain due to nocturnal 
jet bringing speeds to 10 to 15 knots. The approach of a cold front 
will increase west flow well offshore Thursday and Friday. 
However...both features will not meet or exceed Small Craft Advisory 
conditions this week. 


Meffer && 


Aviation...main concern again is convection. Scattered rain showers and 
thunderstorms and rain are developing mainly north of the 10/12 corridor. Convection 
should quickly dissipate tonight but tomorrow convection should have 
greater coverage as a weak front tries to slip into the region late 
tomorrow. /Cab/
