NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
427 PM CDT sun Mar 29 2015 


Synopsis... 
latest surface analysis along the Carolinas coast with the ridge 
axis extending southwest to the northeast Gulf. In 
addition...frontal boundary was located from Wisconsin to north 
central Texas and southerly flow from Texas coast/central Gulf 
Coast to Michigan. Upper air analysis showed a short wave from 
Wisconsin to eastern Kansas. Precipitable water value on a planer 
view indication a surge ahead or east of the short wave with three 
quarters of an inch over lower Mississippi Valley. 


&& 


The light southerly winds and mostly clear to partly cloudy skies 
will advect higher dewpoint temperatures...and this continues to 
look favorable for areas of fog to develop late tonight through 
early Monday morning. The lows tonight are expected to be around 
10 degrees warmer than this morning. 


The warming trend is expected to continue as the short wave moves 
east through late Monday. Associated frontal boundary will dive 
southeast. With the short wave pushing east...the frontal boundary 
will east to west just north of the area Monday. In addition...500 mb 
temperature lower to -17c across Mississippi coast. Northwest flow erode 
the cap in place. As a result...instability with modest cape 
values around and above -20c will lead a few storms with small 
hail for Monday afternoon and evening. The frontal boundary to 
our north will dissipate by Tuesday...however the airmass over the 
forecast area may support of some isolated showers across the 
north zones on Tuesday. 


The main system of concern will be a developing shortwave trough 
over Texas and adjacent Mexico on Tuesday and Tuesday night that 
should move east across the central Gulf Coast region Wednesday 
afternoon and Wednesday night. The models are split with Euro 
going wet and GFS dry. Am continuing to blend the models with a 
slight lean to GFS Wednesday night. Instability will remain in 
play Wednesday night to mention of thunderstorms. 


The models keep some rain around in the wake of the shortwave 
trough through Thursday afternoon...even without any cold front 
moving into the region. This is primarily due to lingering 
moisture and instability with above normal temperatures. 


The westerlies and upper jetstream will be sagging south into the 
upper portions of the Southern Plains and lower Mississippi Valley 
as a series of shortwave trough/disturbances move through. This is 
expected to drive a Pacific cold front through the forecast area 
Friday night and early Saturday. The forcing will not be that 
strong and moisture content not that high...so isolated to 
scattered showers and a few thunderstorms are anticipated Friday 
through Saturday morning with the highest rain chance looking to 
be on Friday night. Temperatures are expected to lower to near to 
slightly below normal Friday night into next weekend.

Aviation... 


Cannot rule out a little fog toward Monday morning...will 
continue to monitor potential. Expect ceilings if any around 
sunrise will scatter out by late morning. 


&& 


Marine... 


No real marine issues to speak of and do not expect significant 
periods of winds greater than 15 knots. Southerly flow on tap for 
much of the work week with no strong weather systems moving 
through the coastal waters.
