Area forecast discussion 
National Weather Service New Orleans la 
751 PM CDT Friday may 29 2015 


..sounding discussion... 


Temperature trace was dry adiabatic to a scattered cumulus deck 
around 2700 feet this evening. The precipitable water value 
remains elevated for late may at 1.58 inches. Weak winds were 
found throughout the profile with the highest wind speeds near the 
surface and a peak wind speed of 18 knots at 46100 feet. 


00z balloon info: a routine flight this evening lasting 103 minutes 
and ascending to a height of 20.6 miles above the ground. The 
balloon burst near Lacombe 7 miles downrange from the office.

Previous discussion... /issued 342 PM CDT Friday may 29 2015/ 


Short term... 


For tonight...ongoing convection will generally begin to dissipate 
within a couple of hours of sunset as daytime heating wanes. In 
fact...expect to see mainly dry weather develop over the area 
through the evening hours. However...after midnight a short wave 
trough that is currently moving through eastern Texas will lift to 
the northeast through the lower Mississippi Valley. This upper 
level trough will bring increased rain chances to northwest 
portions of the County Warning Area...mainly north and west of a Baton Rouge to 
McComb line where a line of showers and thunderstorms could roll 
through around daybreak tomorrow. As this initial trough lifts out 
of the area...another stronger trough will move into Texas. A 
broad area of positive vorticity advection and increasing Omega 
will overspread the area through the day tomorrow and into 
tomorrow night. As a result...expect to see fairly high convective 
coverage by tomorrow afternoon...and have kept likely probability of precipitation in the 
forecast. Convection will be most pronounced farther from the 
coast...and have highest probability of precipitation mainly north of the Interstate 10 
corridor. 


There is little difference in the model solutions on Sunday. 
The upper level trough in Texas will slowly drift into the lower 
Mississippi Valley and an associated cold front will also move 
into the area. With decent lift in place across the area...and 
ample instability to tap into during the day on Sunday...have kept 
likely probability of precipitation in place for Sunday afternoon. Severe thunderstorms 
are not expected...as shear profiles are rather weak with this 
system. However...some stronger thunderstorms could pulse during 
the afternoon hours...producing gusty winds...frequent 
lightning...and locally heavy downpours. Some of the rain may be 
heavy enough to produce some street flooding if the thunderstorms 
train over the same region long enough. Temperatures will remain 
very close to seasonal norms in the middle to upper 80s during the 
day and the upper 60s and lower 70s at night. 


Long term... 


Heading into next week...some significant model differences arise 
between the GFS and the European models. The GFS shows a cut off 
low forming over the northwest Gulf and lingering through the 
week as the parent upper level trough lifts to the northeast and 
some lingering vorticity at the base of the trough remains over 
the region. At the same time...an upper level ridge develops over 
the eastern third of nation. This ridge axis will be just east of 
the region...and effectively block the low from moving out of the 
area. However...the Euro solution has the initial upper level 
trough on Sunday continue to progress eastward and stall more over 
the Florida Panhandle for the remainder of the week. It still 
develops the cut off low as the parent upper level trough pulls to 
the northeast...but the low is much weaker and the ridge far more 
dominant across the forecast area. Basically...the GFS shows a 
cooler and much wetter solution and the Euro shows a warmer and 
much drier solution for the area. Given the large 
differences...and the fact that both models indicate that a cut 
off low will form somewhere over the Gulf...have went with a blend 
of the model solutions for next week. Thus...have went with chance 
probability of precipitation for each day during the peak heating hours. Convection could 
linger into the evening hours...but only expect to see isolated 
convection in the overnight hours due to a lack of instability. 
In terms of temperatures...decided to hedge toward the 
climatological norms for early June. 


Aviation... 


Currently VFR conditions at all terminals...generally with cumulus 
fl025-040. Widely scattered convection across the entire area with 
potential for any of the terminal sites to be affected during the 
afternoon. In most cases...any impact should be short-lived. 
Convection should dissipate by sunset with general VFR conditions 
overnight. Currently...conditions on Saturday appear to be a repeat 
of today. 35 


Marine... 


A very benign weather regime will continue across the marine zones 
through the forecast period. Winds will generally be from the 
south and southeast through the period at around 10 knots as a 
ridge of high pressure extending across the eastern Gulf of Mexico 
stays in place through the middle of next week. There could be a 
weak front that slips toward the tidal lakes on Sunday...but this 
front will wash out before reaching the waters. In 
addition...during the overnight hours...some weak landbreeze 
effects could impact the Mississippi Sound and Lake 
Borgne...resulting in a period of offshore winds around daybreak. 
These winds will quickly shift back to onshore by mid-morning. 
This trend will be most pronounced early next week.
