NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
409 am CDT Wednesday Aug 5 2015 


Short term... current upper level analysis shows a ridge centered 
south of the 4 corners and a trough dipping across the Great Lakes 
and northeastern U.S. That puts the County Warning Area in somewhat of a zonal 
region south-southwest of the trough. At the surface...Bermuda ridge 
extends across the Gulf of Mexico and continues to bring increasing 
moisture into the area while low pressure is located over West 
Texas. 00z lix upper air sounding showed that precipitation water has risen above 
2 inches. A weak residual trough axis still exists along the coast 
and will be the focus for convection today. In fact...some 
thunderstorms are already impacting the Mississippi coast this 
morning. Offshore storms will persist through middle morning before 
dwindling. By then...convection will begin to initiate inland over 
la and MS. Greatest probs will be over the eastern half of the 
County Warning Area...east of btr. Rain activity and increased cloud cover will keep 
highs more limited in that area. Further west...should still see 
highs slightly above average. 


Long term... rain chances will remain higher again on Thursday as a 
weak upper level trough tracks southeastward across the middle 
Mississippi Valley. This trough will keep the eastern side of an 
upper ridge over the area eroded and thus reduce subsidence to 
result in increased convection coverage. 


Going into the end of the week and the weekend...the upper trough 
will push east while ridge builds back in from the west. Latest runs 
of models suggest a stronger and further eastward position of the 
ridge than 24 hours ago. It does however agree with model outputs 
from 12 hours ago. So that consistency aides in the reasoning for 
tapering off probability of precipitation even more for Saturday and Sunday. Although 
isolated storms are possible...not looking like widespread 
convection. At the same time...temperatures will be soaring to well 
above normal. Model 925mb temperatures near 30 degrees suggests very hot 
temperatures are coming. Could even see a few locations touch triple 
digits Sunday and Monday. Heat advisory conditions definitely 
possible under those conditions.

Aviation... 


Vrf conditions will continue through Tuesday morning. Isolated 
mainly afternoon rain showers/thunderstorms and rain are possible...however chances appear too 
low at this time for inclusion in the tafs. 18 


&& 


Marine... 


The frontal boundary continue to retreat north of the coastal waters 
this morning and westerly flow has replaced the northerly flow. The 
weak surface low over North Florida is expected lift northeast 
through Tuesday. Ridge will rebuild over East Gulf while a trough 
develops over the plains. These features will create a more 
southwest flow over the area Tuesday through Saturday. 18
