Area Forecast Discussion
National Weather Service New Orleans LA
416 AM CDT Fri Mar 23 2018

Moderating high pressure settled over the Deep South this morning
will move east through Saturday with onshore flow becoming better
established over the central Gulf Coast region through the
weekend. Upper ridging to the west will present a northwest flow
regime into the Lower Mississippi Valley that will usher a frontal
boundary into the mid-section of the Gulf States but stalling
north of the forecast area. The greater focus will likely remain
north enough to preclude mention of rain through Sunday.
Temperatures are a blend of guidance with a slight bias to warmer

Frontal zone retreats north as a warm front through the Plains
States and middle Mississippi Valley as deep troughing takes place
in the desert southwest. This is likely to maintain a corridor of
persistent steady rainfall through middle of next week that would
exacerbate ongoing high river flows for extended flooding impacts
along the mainstem heading into April. This rain area may become a
forecast challenge in the latter part of the forecast cycle but
should return better chances of rainfall to the local area
Thursday into Friday of next week. 24/RR


Some light fog has been observed at a few TAF sites. I do not expect
this fog to linger through the morning hours. Otherwise expect VFR
conditions to prevail through the TAF period. 13/MH


High pressure over the forecast area will shift to the east today
opening the Gulf of Mexico into the area. The pressure gradient will
tighten in response deepening leeside trough in the Central Plains.
This will cause winds to elevate into the 15 to 20 knot range this
weekend. This corresponds to exercise caution criteria. Winds
decrease on Sunday before picking back up for early next week. A
strong long-fetch regime is expected to develop with onshore flow
bringing near Small Craft Advisory conditions and above normal
