area forecast discussion
national weather service new orleans la
408 pm cdt Wed mar 20 2019

Discussion The stretch of very pleasant dry weather continues
across the region. It was about as dry as yesterday with the rh
values falling into the lower 20s across much of the area however,
along the ms coast where a weak seabreeze developed and allowed a
little gulf moisture to move in with rh values in the 40 to 50%
range.

As for the forecast tonight through next weekend, things will be
quiet. There is a strong S W currently exiting the southern plains
and moving into the lower ms valley. This will move through
overnight and actually push a weak cold front across the region. Not
sure how much of a cold front this can really be called as both
temps and dewpoints don't really change and the only sensible weather
change will be winds shifting around. The main thing this wind shift
will do is keep moisture from recovering until Saturday when return
flow finally sets back up. Due to the dry conditions and low
dewpoints lows will once again fall into the 40s and lower 50s
tonight and tomorrow night. If dewpoints are a tad lower across
southwestern ms then low may be able to drop to the upper 30s but
will hold hold off on that at this time.

Northwest flow over the region tomorrow and tomorrow night will give
way to a building ridge Friday. This will lead to ll temps
moderating an highs working its way back into the lowers 70s across
much of the region by Friday.

This weekend the ridge overhead will continue to slide east and we
move under zonal flow by late Saturday as another strong disturbance
comes across the rockies and into the plains. The support with that
system will quickly swing nne well before getting into our area and
thus keep us dry. Sunday we remain under zonal flow and high
pressure at the sfc. Ll moisture will continue to slow increase and
ll temps will inch up.

Early next week rain may finally move back into the region. The
disturbance that moved across the rockies Saturday will not move
very much Sunday but it will begin to get kicked out to the east
Monday as another strong piece of energy drops out of the pac nw.

These two pieces will merge and drop southeast across the lower ms
valley Monday night and Tuesday. A sfc low will take shape somewhere
across the lower ms valley and move east into the tn valley. It will
drive a cold front through the region. This will bring convection to
the area possibly as early as late Monday maybe even a few strong to
severe storms. It may also bring another quick shot of cooler air to
the region. Cab

Aviation VFR conditions prevail at all area airports through
the day into Thursday. No visibility issues are expected. Ceilings
will lower some with an approaching shortwave cold front, but this
should not cause any issues with flight conditions. Also, a wind
shift is expected as this front passes through our area. Msw

Marine High pressure currently in control over the region with
light winds over much of the coastal waters. We will see a weak cold
front overnight tonight but the only real change will be a wind
shift with offshore flow holding tight for about another 24 hours.

High pressure will then sit right over the area Friday so look for
winds likely to be light and dominated by diurnal fluctuations. High
pressure slides east late Friday and onshore flow will begin to
return. Cab
