NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
949 PM CDT Friday Jul 31 2015 


Update... 
updated forecast to keep mention of showers and thunderstorms 
confined to southeast Louisiana coastal areas...removing mention 
from metropolitan New Orleans and the Mississippi Gulf Coast. Offshore 
the coverage of thunderstorms is scattered to numerous and strong 
to severe thunderstorms have been common with numerous special 
marine warnings issued. The drier air is pretty much about what 
was expected...so only had to make some minor adjustments to the 
hourly temperatures...dewpoints and lows tonight. Updates have 
been sent. 22/dew point 


&& 


Previous discussion... /issued 800 PM CDT Friday Jul 31 2015/ 


.Sounding discussion... 


The first item to note on the sounding this evening is drier air 
through the profile compared to what has been measured lately with 
precipitable water at 1.72 inches. There is an elevated inversion at 800 mb from 
the washed out front that moved though. There are a couple other 
subtle subsidence inversions aloft... like at 390 and 290 mb. 
Winds are northerly from the surface to 3500 feet then become 
northeasterly through the rest of the profile. 


Krautmann 


Previous discussion... /issued 325 PM CDT Friday Jul 31 2015/ 


Synopsis... 


Frontal boundary has become stationary along the Louisiana 
coastline. Isolated convection along the front from just south of 
Mobile to near Southwest Pass and on to the southwest. Drier air 
lags the front by about 150 miles...with the 70 degree dew point 
line from just south of McComb to Baton Rouge. Still seeing middle 70 
dew points along the Mississippi coast and south of Interstate 10. 
Temperatures also maxing out a few degrees lower today than the 
last several days. 


Short term... 


Do not expect much more southward progress of frontal system or 
dry air. Moisture will again surge back to the north Sunday and 
Monday. Will leave isolated probability of precipitation over southern half of area 
through Saturday night...then raise about 10 percent for Sunday 
and Monday. Have gone above guidance lows for tonight and Saturday 
night...but would not take much more southward progress of drier 
air to bust temperature forecast. Do not expect afternoon highs to 
change very much through the weekend. 35 


Long term... 


Not much day to day change during the extended forecast period. 
Isolated to scattered convection each afternoon/early evening. Not 
out of the question an organized convective complex or two could 
develop in weak northwesterly flow...but timing of impulses that 
far out is problematical. Temperatures will remain several degrees 
above normal through the work week. 35 


Aviation... 


VFR conditions will be found at all of the terminals through the 
forecast period as a dry and more stable airmass settles over the 
area. /32/ 


Marine... 


Cold front has slipped into the Gulf but has now stalled along 
the coastal waters. With this winds will generally remain light. 
Most likely area with moderate winds will be overnight near and 
just south of the MS sound where are typical nocturnal jet 
develops. /Cab/ 


Decision support... 


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