NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
347 PM CDT Thursday Sep 3 2015 


Short term...weak upper level inverted trough over the 
southeastern Continental U.S. Continues to be the focus for shower and 
thunderstorm development while developing ridge to the west 
keeping things drier. Local radar currently shows scattered 
convection over sela and southern Mississippi with generally 
outflow driven movement. Offshore waters were nearly encompassed 
by a swath of light to moderate rainfall. This activity has been 
on a downward trend and will continue to do so for the next few 
hours until its dissipated. The same in general is expected 
inland with some lingering convection between 00z and 06z. Beyond 
06z...mesoscale and medium range models suggest new sh/ts development 
offshore south of la. Have kept probability of precipitation offshore higher overnight to 
account for this. 


Long term... upper level high developing over Texas and Oklahoma 
will generally remain in place for a couple days before retreating 
southwest early next week. This positioning will keep the County Warning Area on the 
outer fringes of this ridge and still under influences of weak 
troughing to the east. So thinking daily coverage in the 20 to 40 
percent range can be expected through possibly the middle of next 
week. 


Meffer 
&& 


Aviation... 
scattered convection producing brief MVFR conditions. 
Areal coverage is fairly small near terminals and using thunderstorms in the vicinity for 
most terminals. May be able to remove thunderstorms in the vicinity before the 00z taf 
package at most locations. 


Overnight should see mainly VFR conditions...with potential for MVFR 
visibilities at khum. Should start seeing at least isolated 
convective development around 16z on Friday...similar to today. 


35 
&& 


Marine... a deep tropical moisture axis will remain over the Gulf 
from near the Yucatan northward to the north central Gulf Coast. 
This weakness will keep higher chances of ts activity in the coastal 
waters through the forecast. Winds and seas will be higher near 
scattered ts. Wind gusts could be as high as 30 knots with the 
strongest activity. Outside ts activity conditions will remain 
rather benign with a weak pressure gradient. Nocturnal activity will 
be the most abundant while there will be a general decrease in 
activity during the late morning through late afternoon hours.
