NWS Forecaster Discussion




Area forecast discussion...updated 
National Weather Service New Orleans la 
836 am CDT Wednesday Apr 23 2014 


Short term... 
reminder that Wednesday is weekly radio test day around 11 am this 
morning. 


Long term... 
the next severe weather potential statement issuance will introduce a chance of strong to 
possibly severe thunderstorms for early next week...based on 
latest model trends and Storm Prediction Center 4-7 day outlook. No other changes at 
this time. 


&& 


Sounding discussion... 
no issues with flight this morning. An overly dry sounding above 
810 mb with just some moderate saturation with 5c depressions from 
surface inversion to base of subsidence inversion at 810 mb. Quite 
stable with a showalter of 6...lifted index 0.6. Precipitable 
water 0.79 inches is about one-half inch less than previous 12 
hours. Winds calm to light NE surface to 5kft...northwest 5-15 knots to 
17kft...a layer of SW 10 knots to about 22kft...then northwest 10-55 knots 
above. Peak wind 280/55kt at 50.2kft. Double tropopause structure 
with a warm -58.2c at 200mb...then -71.9c at 106mb. Balloon burst 
28 miles east-southeast at an altitude of 32625 M/ 20.27 miles up in the 
Mississippi Sound about 6 miles S of Buccaneer State Park on the 
Hancock County coast. 24/rr 


&& 


Previous discussion... /issued 700 am CDT Wednesday Apr 23 2014/ 


Synopsis... 
latest surface analysis showed a deep 994mb low over Maine with a 
cold front extending south to Georgia to Florida Panhandle to 
Mississippi Delta mouth to southwest Louisiana. Dewpoint readings 
were 65 to 70 south of the front 55 to 65 north of the front. 
Patchy dense fog was present along and immediately north of the 
front...Houma Airport was quarter mile...galiano Airport was a 
quarter...Patterson was half. However...net cams around Houma 
indicated visibility restrictions above 2 miles. Will handle fog with 
Special Weather Statement for patchy dense fog this morning. Water vapor imagery showed 
drying in middle and upper atmosphere over the Gulf Coast due to northwest 
flow over the Gulf Coast. Upper air charts showed a ridge axis 
over the plains and a trough axis from Washington to Arizona. 18 


Short term... 
weather systems are expected to continue their progression from 
west to east. Frontal boundary of the south half of the forecast 
area is expected to dissipate today. Upper level trough axis over 
The Rockies will track east to the plains and deepen the surface 
trough/front over the plains today. This feature will allow surf winds 
to become southerly from the central Gulf Coast to the middle 
Mississippi Valley by late tonight. Low level moisture will 
slightly increase. Mostly clear skies and radiational cooling to 
saturation is likely Thursday and Friday mornings. With this 
said...the forecast will remain dry today and Thursday. 18 


Long term... 
upper level trough over the Great Basin will track east. With the 
axis already negatively tilted and northern track equate to low to 
none chances of rain as the axis approaches the forecast area 
Friday through Saturday across the north half. The next system 
will take a farther south track across rockies over the weekend. 
Moisture axis will approach the northwest zones Sunday night and 
over the forecast area Monday. Will maintain rain chance and 
possibly strong convection. Albeit weak south flow at times over 
the weekend...instability with cape around 1500 j/kg in place on 
Monday before the axis and surface front sweep through early 
Tuesday according to GFS and European model (ecmwf). Both show an evolution of the 
trough into a deep closed low over Central Plains late Monday then 
they diverge after Tuesday. GFS keeps the low over the middle south 
through Tuesday then move southeast along the I-20 corridor this 
track will bring a cloudy sky...below norm Wednesday and Thursday 
and a chance of cold rain across the north zones the Continental U.S.. European model (ecmwf) 
keeps a closed low but farther north. We lean to GFS with temperatures 
but not as cold and just cloudy and no rain for now after the 
frontal passage. 18 


Aviation... 
patchy fog has begun to develop and will result in IFR to MVFR 
conditions this morning at several airports...especially from 
08-13z. The lowest conditions are likely at khum where visibility 
restrictions are currently the lowest. Otherwise...VFR conditions 
will prevail through this evening. 


Meffer 


Marine... 
fairly benign conditions expected over the coastal waters from now 
through middle weekend. High pressure currently centered over the 
central Gulf of Mexico will gradually shift eastward. Southerly 
winds will generally be around 10 knots with seas 2 feet or less. 
Going into Sunday and beyond the winds/seas will increase as the 
pressure gradient tightens due to surface low developing in the 
Southern Plains. Exercise caution conditions could exist as early as 
Sunday afternoon and persist through Monday. Models indicate that a 
cold front will swing through Tuesday. It remains to be seen how 
strong this boundary is.
