NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
330 PM CDT Tuesday Jul 29 2014 


Short term... 


Through tomorrow...a dry and very stable airmass will dominate the 
region as a broad surface high centered over the southeastern 
Continental U.S. Remains in place. As a result...expect mostly clear skies 
and very mild conditions across the forecast area. Daytime highs 
will run around 5 degrees below normal and overnight lows will be 
a good 10 degrees below average for late July. 


The dry weather will come to and on Thursday...as a vorticity maximum 
slides down the backside of a strong long wave trough parked 
over the eastern third of the Continental U.S.. this vorticity maximum and an 
associated frontal boundary will slide into the region early 
Thursday and then turn stationary along the Gulf Coast as the 
parent upper level trough begins to lift to the north and east. 
This low level boundary...combined with a broad area of higher 
Omega associated with the lobe of upper level vorticity will serve 
as a focus for convective activity beginning Thursday afternoon 
and persisting into Friday. Have bumped probability of precipitation to likely...as 
confidence in the front stalling over the region has increased. 


Long term... 


The long wave trough linger over the eastern third of the nation 
through the weekend...and the frontal boundary will continue to 
sit over the forecast area...though it will gradually turn more 
diffuse with each passing day. Have lowered probability of precipitation slightly for 
Saturday and Sunday from around 50 percent to 30 percent by Sunday 
as the frontal boundary washes out and the low level focus for 
convective activity wanes. However...there will continue to be a 
higher than average chance of rain each day due to the continued 
upper level support from the trough and weak vorticity maxima 
slipping through the area. 


The upper level trough will finally begin to lift out of the area 
on Monday and Tuesday...but a region of cut off vorticity will 
linger over the Gulf south through Tuesday. This weak area of 
forcing will continue to keep chance probability of precipitation in place both days. The 
convection will be much more diurnal in nature...with the greatest 
risk occurring from late morning through the afternoon hours. 
Expect to see coverage of convection be greater during the 
offshore waters during the overnight hours. As the seabreeze 
develops each day...convection will develop along this mesoscale 
boundary and then further convection will spark off the resultant 
outflow boundaries. This pattern will basically be the normal 
Summer routine of afternoon convection...but with some increased 
upper level support to keep the convection going longer than 
normal. 


&& 


Aviation... 


Drier air will continue to filter in from the north and keep 
conditions VFR through Wednesday. 22/dew point 


&& 


Marine... 


Winds will generally be 10 knots or less over the coastal waters 
through the forecast period. The winds will be highly variable 
through Thursday as a frontal boundary washes out over the coastal 
waters. On Friday and continuing through the weekend...winds will 
turn more southerly...and should remain from the south. 
Overall...no significant impacts to the boating community outside 
of convection are expected through early next week.
