NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
339 PM CDT Wednesday Apr 16 2014 


Short term... 


Tonight through Friday... 


No significant changes to the ongoing forecast. Strong subsidence 
associated with a deep layer ridge remains over the area today. 
This subsidence has resulted in low humidities and mostly clear 
skies...and these conditions will continue through the overnight 
hours. The ridge axis will pull to the east during the day 
tomorrow. As this occurs...onshore flow will develop bringing 
increased low level moisture into the region. Expect to see a 
broken stratocu field develop during the day tomorrow as a marine 
layer airmass moves in. A few shallow marine layer showers may 
develop during the afternoon hours...as instability below a middle- 
level cap increases. Temperatures will continue to moderate as 
onshore flow develops...with highs climbing back into the upper 
60s and lower 70s tomorrow afternoon. 


Conditions will further destabilize Thursday night as a fast 
moving upper level trough swings through the Gulf south. Increased 
Omega and a higher precipitable water airmass associated with this feature will 
allow for scattered showers and a few thunderstorms to develop 
over the forecast area. A surface low will form over the central 
Gulf of Mexico during this period...which will keep the highest 
probability of precipitation confined to coastal areas. More isolated coverage is expected 
around southwest Mississippi and the Baton Rouge area. The upper 
level trough axis will quickly pull east of the area on 
Friday...with only some lingering showers expected over eastern 
zones Friday morning. Strong negative vorticity advection and 
increased subsidence will then move over the area Friday afternoon 
as another deep layer ridge slides through Texas. Temperatures 
will continue to warm...with readings climbing back into the 
middle to upper 70s by Friday afternoon. 


Long term... 


Friday night through Wednesday 


A fairly benign weather regime will develop over the forecast area 
in the extended period. Strong deep layer ridging will continue to 
dominate the Gulf south over the weekend...resulting in dry 
weather and warm temperatures for both Saturday and Sunday. Highs 
will rise into the lower to middle 80s each day. These readings 
will slightly warmer than average. Heading into next week...the 
ridge will flatten out slightly as a shortwave trough slides 
through the Midwest. However...the ridge axis will remain in firm 
control of the forecast area. As a result...dry weather and warm 
temperatures will persist on Monday. 


Another short wave trough will then deepen over the Southern 
Plains and slide into the lower Mississippi Valley on Tuesday. 
This trough will finally break down the ridge...allowing for some 
isolated convection to develop as the middle-level cap weakens. 
However...overall forcing with this feature will relatively 
weak...so more widespread convection is not expected. Ridging will 
rebuild over the area on Wednesday...resulting in a return to dry 
and warm conditions. 32 


&& 


Aviation... 


VFR conditions are generally expected to prevail through 09z. Middle 
layer will stream in across the area from west to east affecting btr 
first and other taf points by 14z. MVFR ceilings may impact the taf 
sites across the forecast area toward daybreak Thursday and 
continued broken to overcast layer between 2500 to 3500 feet through 
Thursday. 18 


&& 


Marine... 


A surface low will develop over the central Gulf of Mexico during 
the day tomorrow and transit into the eastern Gulf of Mexico by 
Friday. This low will bring increased easterly winds of 15 to 20 
knots and possibly even in excess of 20 knots to the Gulf coastal 
waters. Seas will also rise as these winds increase. The 
combination of wind waves and swell will push seas up to around 7 
feet in the Gulf waters east of the mouth of the Mississippi. As a 
result...Small Craft Advisory flags will likely be needed for 
Thursday and Friday. Conditions will begin to improve Friday 
afternoon as the low pulls into the Atlantic and surface ridging 
spreads back into the area. Easterly winds will continue but will 
fall to 10 knots or less beginning Friday night and persisting 
through early next week. Seas will fall to 2 feet or less by the 
weekend.
