NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1032 am CDT Thursday Jul 24 2014 


Sounding discussion... 
12z sounding was very moist and slightly unstable with a precipitable water of 
2.06 inches...and a mixed layer cape of 879 j/kg. Low to middle level 
winds are mostly light south to southwest 5 to 10 knots all the 
way up to 150 mb. Local techniques for downburst/wet-microburst 
potential indicate moderate to high potential for well below 
severe gusts around 30 miles per hour. Low level cape and wind profile is 
once again favorable for waterspouts during the morning hours.

Previous discussion... /issued 423 am CDT Thursday Jul 24 2014/ 


Synopsis... 
latest upper air analysis showed a large anticyclonic circulation 
centered over the Central Plains and another just east of Florida. 
A weakening upper level low was located just southwest of forecast 
area. 500 mb temperatures are -7c across south Louisiana and -6c across 
southern Mississippi. Latest surface analysis continue to show a 
very weak pressure gradient from south Texas to North Florida with 
a 1mb difference. Precipitable water values on a planer view at 
00z showed values above 1.8 inches from Upper Texas coast to North 
Florida and values less than 1.5 inches over middle and upper 
Mississippi Valley. 18 


Discussion... 
upper level low will continue to drift southwest and weaken today. 
At the same time...upper level high will drift southwest over 
Texas Panhandle and allow the dry air to push south over the lower 
Mississippi Valley late tonight. Northeast down Glide winds 
associated with high building over east over the lower Mississippi 
Valley will increase 500 mb temperatures at up to -5c this afternoon through 
the weekend. This will suppress a majority of convection through 
the weekend and allow afternoon temperatures to rise into the lower to 
middle 90s due to less clouds and increased heights. Wind flow at the 
surface and lower levels will remain weak today and through the 
weekend. Therefore...isolated to scattered convection will develop 
along the sea and lake breeze boundaries each afternoon...isolated 
convection is expected elsewhere. 


Next week models still point to an active jet pattern and an upper 
trough that will dig across the the eastern part of the country 
Sunday into Monday. This will result in a cold front being pushed 
into the forecast area Tuesday and stalling over the south half of 
the forecast area Wednesday and Thursday of next week. Rain 
chances will increase around the front Monday through Thursday. 18 


Aviation... 
patchy light fog impacts should be limited to mcb and hum this 
morning...with those locations seeing visible about 5sm. Otherwise... 
VFR conditions are expected to prevail outside any localized 
convective impacts Thursday afternoon at each taf sites. Expect 
middle level cumulus field with ceilings around 3-4 kft. Much of the 
convection should dissipate by the evening with an earlier start 
near the coast. 


Meffer 


Marine... 
main Bermuda surface high extends into the Gulf of Mexico with a 
sub-like center being maintained in the eastern Gulf of Mexico 
today through the weekend. This will keep flow generally 
southwest with speeds ranging mainly from around 8-13 knots and 
seas 2 feet or less. A weak summertime cold front will approach 
the coastal waters early next week. At this time it appears the 
boundary will stall across the offshore waters which will causes 
winds to become parallel to the boundary. 


Meffer 


Decision support... 
dss code...green. 
Deployed...none. 
Activation...none. 
Activities...slurry support. 


Decision support services (dss) code legend 
green = no weather impacts that require action 
blue = long fused watch/warning/advisory in effect or high 
visibility event 
yellow = heightened impacts with short fused 
watch/warning/advisory issuances; radar support 
Orange = high impacts - slight to moderate risk severe; nearby 
tropical events; hazmat or other large episodes 
red = full engagement for moderate to high risk severe 
and/or direct tropical threats; events of National
