NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1152 PM CDT sun Aug 2 2015 


Aviation... 


Tranquil conditions will continue with VFR expected through Monday 
evening. Isolated mainly afternoon rain showers/thunderstorms and rain are 
possible...however chances appear to low at this time for 
inclusion in the tafs. 22/dew point 


&& 


Previous discussion... /issued 338 PM CDT sun Aug 2 2015/ 


Synopsis... 


Frontal system remains just off the Louisiana coast this 
afternoon. Weak low pressure south of Tallahassee will move 
northeast across Florida into the Atlantic over the next 24 hours. 
Isolated showers and thunderstorms are occurring over the coastal 
waters just south of the front. Temperatures again have warmed 
into the lower and middle 90s. Dew points across the area are 
mainly in the 60s away from marine influences. 


Short term... 


Difference in models in the short term is when moisture returns. 
Low pressure moving into North Florida has tightened the gradient 
a little today and has pulled dry air a little further 
southward...and slowed the onset of onshore flow across the area. 
Any southerly winds across the area right now are more due to sea 
breeze than any synoptic feature. GFS keeps moisture south of most 
of the area through Tuesday night...which may be a bit too long. 
Will compromise between the drier GFS and the somewhat more moist 
NAM/European model (ecmwf) solutions. Probability of precipitation will range from slight chance north to 
chance south Monday and Tuesday...with chance probability of precipitation for much of the 
area on Wednesday. Little day to day change in high temperatures. 
For low temperatures...will trend toward the cooler numbers for 
tonight...gradually warming them the following 2 nights. 35 


Long term... 


Upper ridging over the southern rockies will slowly edge to the 
east late in the week. European model (ecmwf) moves the ridge to the east more 
aggressively than does the GFS...and may be slightly overdone. 
Opted not to make significant changes to the extended at this time 
to fit with surrounding offices. This will keep chance probability of precipitation in the 
forecast for mainly afternoon and early evening convection over 
the weekend. Not much change in temperatures anticipated at this 
time. 35 


Aviation... 


VFR conditions to prevail and linger for at least another 24 hours. 
Gulf moisture should begin to resurge northward Monday afternoon for 
some VFR based clouds. Convection should remain confined to lower 
parishes of la where khum and kmsy may have a shot from isolated 
showers and brief thunderstorms and rain generally after Monday 19z. 24/rr 


Marine... 


Northerly flow near shore holding better than anticipated in 
large part to low pressure circulation over Apalachee Bay Florida 
maintaining Continental influences farther west. As that feature 
lifts along the eastern Seaboard a return to onshore flow likely 
to onset with Gulf Breeze circulation Monday...then persisting 
through the week. 24/rr 


Decision support... 


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