Area forecast discussion 
National Weather Service New Orleans la 
816 PM CDT Friday Sep 19 2014 


..sounding discussion... 


Dry air has arrived over much of the central Gulf Coast as noted 
on WV imagery this evening. This means conditions are quite 
comfortable for the middle of September. With the column drying 
out...precipitable water values are also dropping and are at 1.45 
inches. This is about a half inch lower than this morning/S 
sounding and about a quarter inch below the climatological value. 
Instability has also decreased with MLCAPES calculated near 150 
j/kg and the lifted index around -2. Temperatures generally followed 
the pseudo adiabats above 700mb with the exception of temperature 
inversions around 575mb and 430mb. Low level winds averaging 15 to 
25 knots from the east carried the balloon to Lacombe before middle 
and upper level winds from the northwest carried the balloon over 
Lake Pontchartrain and east of New Orleans. A maximum wind speed 
of 43 knots was located at 32500 feet above the ground. 


00z balloon info: a successful flight this evening that reached a 
height of 21 miles above the ground bursting 26.7 miles downrange 
just east of Chalmette.

Previous discussion... /issued 343 PM CDT Friday Sep 19 2014/ 


Synopsis... 
latest surface analysis showed a stationary boundary from North 
Florida to coastal Louisiana and weak high pressure from 
Mississippi to northeast Continental U.S.. surface dewpoints range from the 
middle 60s across south Mississippi to lower 70s along the 
Louisiana..dry to the northeast. Upper air charts showed a 
positively tilted trough axis from the middle Atlantic coast to the 
north central Gulf. Water vapor showed the demarcation line from 
Pensacola to the Mississippi Delta to Lake Charles with middle layer 
drying north. Wrf3km showed isolated to scattered showers developing 
over the north half zones this afternoon but dry air aloft should 
hamper deep growth and convection. 


Short term... 
northeast winds north of the boundary will continue to advect in lower 
60s across the north half zones tonight. Convection should dissipate by 
sunset and clearing should allow northern points to radiate. As a 
result...overnight will dip into the upper 60s across the north 
zones but remaining the 70s for south zones and repeat possibly a 
degree or two cooler for Sunday morning. Upper level trough just to 
the east will slowly through the weekend maintain a light north 
flow over the lower Mississippi Valley. Precipitable water values 
should below 1 inches by Saturday and remain at or below 1 inch 
through the weekend. Therefore...will only keep slight rain 
chances along the Louisiana coastal and coastal waters. 


Long term... 
upper level trough over the upper plains will dive southeast over 
the Great Lakes and push a trough axis across the lower 
Mississippi Valley Monday. Moisture will be limited however...middle 
layer instability will be in place before the passage axis and 
associated frontal boundary. Will maintain isolated thunderstorms and rain Monday 
through Monday evening ahead of the boundary. 1000 to 700mb layers 
behind this trough decrease only 10 to 15 meters. However...surface 
dewpoints are expected to drop into the lower 50s across the north 
zones by Tuesday morning according to Euro and GFS. Will not go as 
low as mex numbers across the north...but these temperatures will provide 
ac relief Monday and Tuesday nights. With the trough moving 
through the northeast Continental U.S....a high will develop and amplify over 
the Ohio Valley...creating a more east flow over the Gulf Coast 
Thursday into Friday...thus increasing rain chances across the 
south zones. 


Marine...a weak area of low pressure in the central Gulf has 
tightened the pressure gradient across the coastal waters and will 
remain in place for another 24 hours. This is leading to winds above 20 
kts with higher gusts in much of the coastal waters and thus have 
issued a scy for all marine zones outside of the tidal lakes and 
sounds. Seas will rise to as much as 7 feet in the outer waters east 
of the MS river. This low will pull to the east by Sunday...allowing 
the pressure gradient to decrease somewhat for Sunday and Monday. 
Expect to see easterly flow of around 10 knots and seas dropping to 
2 to 3 feet during this period. A cold front will then pass through 
the marine zones Tuesday into Tuesday night. As some drier air 
advects over the area...a brief increase in winds back toward 
exercise caution range will be possible. /Cab/ 


Aviation...overall VFR conditions should rule for the most part but 
for the remainder of the afternoon and into the very early evening hours some 
very shallow rain showers will impact portions of the region. Once we lose 
the daytime heating what ever convection is out there will 
dissipate. Once this occurs look for some cumulus around 4-5 feet but 
overall skies should become clear. /Cab/ 


Decision support...

Deployed...none. 
Activation...none.
