Area Forecast Discussion
National Weather Service New Orleans LA
338 PM CDT Fri May 26 2017

.DISCUSSION...
Temperatures will continue to warm and moisture levels will
increase over the weekend as a flat mid level ridge builds over
the central Gulf Coast region during the period. Meanwhile, an
upper low/trough will move out of south central Canada and into
the upper Mississippi Valley late in the weekend and translate
eastward across the Great Lakes region and into the northeast
conus through the middle of the week. This feature will push a
weak cold front into the forecast area Memorial Day into Tuesday
with the boundary gradually becoming diffuse thereafter. Rain
chances will be on the increase late in the weekend across
primarily the northwest sections of the P/CWA, and then across
the entire forecast area Monday and Tuesday with the
aforementioned boundary serving as a focus. Rain chances will
gradually diminish as the week progresses with flat mid level
ridging again building across the Gulf Coast states. 11

.AVIATION...
Expect VFR conditions to prevail through the evening with southerly
winds generally in the 10 to 15 knot range. Winds will subside a bit
after sunset, and lower cigs will gradually build in after midnight.
Expect MVFR or even a few hours of IFR cigs at most terminals toward
daybreak. Conditions will improve again after sunrise Saturday. 95

&&

.MARINE...
Little change in thinking from the previous forecast. A broad
ridge of high pressure will remain over Florida and the eastern
Gulf through the middle of next week. This will keep a general
onshore wind of 10 to 15 knots in place through the period in the
open Gulf waters. Seas of 1 to 3 feet are also expected through
Wednesday. In the sounds and tidal lakes, a weak front will stall
and dissipate along the Louisiana and Mississippi coastline on
Monday night into Tuesday. Winds should decrease to around 5 knots
or less and turn more variable with the dissipating front in the
area. Waves will generally remain 2 feet or less through the
entire period. 32/95
