NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
327 PM CDT Monday may 4 2015 


Short term... 


No significant changes in the ongoing thinking through the 
remainder of the workweek. A weak inverted trough currently moving 
through the region continues to produce a narrow band of showers 
and thunderstorms over the southwest third of the forecast area. 
These showers and thunderstorms should slowly diminish through the 
evening hours...and expect to see dry conditions by late evening 
across the forecast area. 


Outside of this weak trough...the region will generally be 
dominated by middle and upper level ridge axis stretching across the 
Gulf south and persistent onshore flow on the back side of a broad 
surface high centered over the southeast through Friday. 
Temperatures will remain near or slightly above normal through the 
period...with highs in the middle 80s and lows in the middle 60s. 
There will be a very low chance of rain each day...in the 10 to 20 
percent range...with the highest probability of precipitation on Wednesday when the middle- 
level cap looks to be slightly weaker. Overall...expect little to 
no precipitation to impact the region from late tonight through 
Friday. 


Long term... 


Heading into the weekend and early next week...the pattern will 
turn more active across the Gulf south as the middle and upper level 
ridge axis shifts to the east...and a series of weak upper level 
vorticity maxima slide across the lower Mississippi Valley. These 
weak upper level systems will introduce increasing Omega and 
resultant lift to the area beginning Saturday and persisting into 
Sunday. The initial feature on Saturday will be fairly weak...and 
only expect to see isolated shower and thunderstorm activity that 
day. A much stronger feature ejecting out of The Four Corners will 
slide through Sunday into Monday. Strong positive vorticity 
advection in advance of this feature on Sunday will produce ample 
lift across the area...and have a mix of slight chance and chance 
probability of precipitation in place across the County Warning Area. The highest probability of precipitation are over western 
zones...where the forcing is expected to greatest. 


All of the medium range guidance indicates that the main trough 
axis associated with this four corner system will sweep through 
the forecast area on Monday. Have went with high end chance probability of precipitation 
for the day to reflect the increased forcing throughout the 
atmospheric column...higher moisture content aloft...and overall 
favorable thermodynamic profiles. This day will also have the 
highest threat of deeper convective cells forming. 


&& 


Aviation... 


Low level moisture transport reflected in a rather healthy cumulus 
field across the area. A narrow northwest to southeast band of 
convection continues near the Atchafalaya River. VFR conditions 
should be the rule through at least 06z Tuesday. Cannot totally 
rule out MVFR conditions around sunrise...but winds appear to stay 
near or above 5 knots at most terminals which should prevent fog 
from forming. Probability of precipitation too low for mention in terminals on Tuesday. 35 


&& 


Marine... 


A persistent east-southeast flow of between 15 and 20 knots will 
impact the majority of the coastal waters through Wednesday as a 
tight pressure gradient between a high over the southeast and 
lower pressure over the Southern Plains remains in place. In 
fact...winds will be closer to 20 knots in the outer waters 
tonight and tomorrow...and seas will range from 4 to 7 feet in 
these outer waters. Nearer to shore...seas will generally range 
from 2 to 5 feet through Wednesday. Given these conditions...Small 
Craft Advisory and exercise caution flags are out for tonight. 
The surface high will become more centered over the forecast area 
on Thursday and then linger over the region through Saturday. 
Winds will remain out of the southeast...but the flow will fall to 
around 10 knots. Seas will also drop to 1 to 3 feet across the 
coastal waters.
