NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1120 PM CDT Monday Jul 27 2015 


Aviation... 
VFR conditions along with only isolated afternoon convection is 
expected for the next 24-30 hours all terminal locations. 24/rr 


&& 


Previous discussion... /issued 347 PM CDT Monday Jul 27 2015/ 


Discussion... 
a few showers have just begun to develop along the Mississippi 
and Atchafalaya River basins on the western edges of the County Warning Area. A 
few could intensify into thunderstorms but all activity should be 
fairly short lived and begin dissipating within the next couple 
hours. 


Not expecting much if any rain through Tuesday as an upper level 
ridge continues to build across the central Continental U.S. And provide 
convective subsidence over the area. Highs will remain above normal 
with middle to upper 90s persisting. These temperatures combined with 
low to middle 70 dewpoints will bring afternoon heat indicies to around 
105 degrees... +/- 3 degrees. 


Aforementioned upper ridge will shift back west beginning Wednesday 
and remain over the 4-corners region through the weekend as an upper 
level trough gradually digs across the eastern half of the country. 
This movement of the ridge will open the County Warning Area back up to typical 
afternoon thunderstorms. Rain chances will be in the 30 to 50 
percent range Wednesday Onward. Some enhancement of coverage will be 
possible as a weak area of low pressure over the northwestern Gulf 
of Mexico drifts north and stretches SW to NE while a weak frontal 
boundary moves in from the northwest Friday & into the weekend. 


Meffer 


Aviation... VFR conditions will dominate at all of the terminals 
through the forecast period. A scattered cumulus field ranging from 4000 
to 6000 feet will continue through the afternoon hours. Skies should turn 
clear after 00z as daytime heating wanes. There may be some light 
patchy fog at kmcb and khum around daybreak tomorrow...but risk is 
too low to mention in the forecast for now. If fog forms... 
visibilities may briefly fall to around 3 miles. Overall...a benign 
weather pattern is expected through tomorrow afternoon. 32 


Marine... winds across the coastal waters will generally be 
light...10 knots or less...and rather variable in nature through the 
early part of the work week. By middle week...a broad surface low 
draped across the northeast Gulf northern Florida will draw winds 
into it which will result in nwrly winds over the coastal waters. 
The approach of 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 


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