NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
518 am CDT Monday Mar 30 2015 


Discussion... 


Not a lot of changes have been made to the previous forecast. 
Satellite and radar imagery indicated a shortwave trough moving 
southeast through the Ohio/Tennessee/lower Mississippi Valley 
region. The associated well defined cold front is preceded by a band 
of widespread showers and numerous thunderstorms moving through the 
southeast states with the southwest portion pushing into central 
Mississippi. This front is expected to weaken and slow its southward 
progress as it pushes into south central Mississippi and northern 
Louisiana today...then the front is expected to dissipate tonight as 
high pressure builds in from the southeast and low pressure develops 
over the Southern Plains. Some patchy fog has developed over 
portions of the forecast area...and this will continue until about 
8 or 9 am. 


To the south of the frontal boundary...shallow low level moisture 
will yield precipitable water values just above one inch with only a 
weak capping inversion and moderate instability as temperatures 
warm into the lower 80s in most areas. Isolated showers are 
expected to develop during the middle to late morning...and isolated 
thunderstorms are possible this afternoon...but that will likely 
depend on slightly deeper low level moisture coincident with 
subtle convergence and forcing features in addition to the 
buoyancy from daytime heating. Any thunderstorms that can develop 
will have the potential to become strong and produce gusty winds 
and some hail due to steep middle level lapse rates and relatively 
low wet-bulb zero heights down near 8000 feet. The best boundary 
interactions and highest potential for stronger thunderstorms will 
likely occur near the Mississippi coast and possibly the North 
Shore of Lake Pontchartrain where any southward moving weak 
boundary could interact with the seabreeze and lake breeze. 


A few showers or thunderstorms could linger into the early evening 
hours over extreme southeast Mississippi...otherwise tonight is 
expected to be dry as the atmosphere stabilizes and the shortwave 
moves east of the region. Another setup for patchy fog is expected 
with light southwest winds. Tuesday and Tuesday night are still 
expected to be dry with warm temperatures above the seasonal 
normals. Some patchy radiation fog is expected again late 
Tuesday night into early Wednesday morning. 


The next system of concern will be a shortwave trough moving out 
of the Baja California Mexico region that will move east across central/south 
Texas and adjacent Mexico Tuesday night...and then dampen/weaken 
as it moves into the central Gulf Coast region Wednesday 
night. The models have trended weaker with this system as it 
moves through the forecast area...however the European model (ecmwf) still paints 
fairly widespread light to moderate rainfall amounts Wednesday 
into Thursday while the GFS is drier and more sporadic with the 
areal coverage. The GFS MOS guidance now does not show any pop 
over 10 percent during these periods...however have held onto 20 
to 30 percent chances for showers and some thunderstorms Wednesday 
into Thursday to maintain forecast consistency. 


The westerlies and upper jetstream will be sagging south into the 
Southern Plains and lower Mississippi Valley Friday and Friday 
night 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 mostly 
light quantitative precipitation forecast amounts from 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 into 
Saturday morning across northern areas. Temperatures are expected 
to lower to near to slightly below normal over the weekend. 


22/dew point 
&& 


Aviation... 


Scattered clouds between fl030-040 across the area...but have seen a 
few fog observations in the surface observation. Where wind is 
calm...patchy fog will continue developing. 


Any fog still around at 12z should burn off by 15z with a cumulus 
field expected to develop late this morning. Boundary to the north 
of the area May Draw close enough today with push of shortwave 
across Mississippi to produce isolated convection at kmcb or kgpt 
and will likely continue the thunderstorms in the vicinity mention for the afternoon hours at 
those terminals. Chances too low for a mention elsewhere. 


Issue tonight will again be fog potential. Guidance hitting fog 
harder tonight than it is currently. Where wind drops off to 
calm...fog development will be likely...probably as early as 08z. 
Will deal with this in 12z taf package. 35 


&& 


Marine... 


At 08z...a few elevated rig AWOS observations east of the mouth of 
the Mississippi River in the 15-18 knot range...which would indicate 
exercise caution conditions...but winds should be showing a 
weakening trend as weak low pressure over northeast Mississippi 
pulls away. Will not carry a headline with package issuance...but 
will continue to monitor closely. 


Beyond that...no real marine issues to speak of. Southerly flow on 
tap for much of the work week with no strong weather systems moving 
through the coastal waters. 35
