NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
320 am CDT Wednesday Aug 20 2014 


Short term...just like the previous night it was another quiet yet 
warm one. No convection was noted on the scope through much of the 
night. The biggest difference tonight from last night was temperatures. 
Morning lows may be quite similar but temperatures did drop much faster 
during the evening hours with much of the region in the middle 70s by 7z. 
The exceptions are along the coast where temperatures were still mostly in 
the lower 80s. 


Through the remainder of the work week the models are in very good 
agreement. The middle level ridge will strengthen as expected and by Friday 
a 594dm ridge will be centered over the lower MS valley. As mentioned 
in the last few forecast this will lead to lower probability of precipitation and warmer 
temperatures...and most likely the warmest temperatures we have seen so far this 
season. First for thunderstorms and rain chances...the ridge will provide subsidence 
while warming low and middle levels will lead to a cap. All of this will 
have negative impacts on convection. That said cant rule out isolated 
to widely scattered rain showers and thunderstorms and rain especially along the sela coast where 
seabreeze interactions combine with peak heating in the afternoon 
possibly leading to convection. As for temperatures nothing has changed in 
that respect and it still looks to be hot especially Thursday and Friday. 
H925 temperatures could approach 28-29c and this would lead to upper 90s on 
those days. As for any possibilities of a heat advection it looks like we 
will remain just under criteria. Morning lows should cool off in 
most places to allow for some relief. The exceptions will be in the 
city where lows could struggle to get out of the upper 70s. Afternoon 
heat indicies will approach the middle 100s. So with that said it will 
still be quite warm and oppressive in the afternoon. /Cab/ 


Long term...medium range models are in good agreement through the 
weekend and to begin next week. The models diverge as we get into the 
middle portions of next week but this falls out of the forecast period. 
Trough the weekend and Monday next week the ridge will still dominate 
the region leading to continued hot and mostly dry conditions. As we 
head into Monday night and Tuesday the ridge will begin to shift far enough 
to the northeast allowing weak erlys to increase rain chances. 


As for the tropics...NHC continues to monitor an area of low 
pressure east of the Windward Islands with a 50 percent chance of 
developing into a tropical cyclone over the next 5 days as it moves 
into the Caribbean. Models differ significantly on eventual track of 
this system and with nothing even developed yet it is futile to try 
to forecast where this possible system will go. As always in middle 
Aug...its hurricane season and no matter what you should pay 
attention to the tropics. Updates will be made as necessary if there 
is any change. /Cab/ 


&& 


Aviation... 
VFR conditions will prevail through the period outside of 
convection. Rain chances remain low but scattered showers and storms 
will develop. Not including in tafs this forecast period but rather do 
an update as needed. Otherwise... expect light southwest winds 
generally less than 10 knots and partly cloudy skies with cloud 
bases around 4kft during the day. 


Meffer 
&& 


Marine... 
surface ridge is currently centered in the eastern Gulf of Mexico 
which is keeping winds in a steady SW direction. This high pressure 
will gradually shift to the northern Gulf Coast over the next couple 
days. This will cause winds to relax and become more variable in 
direction. Seas will respond to this wind reduction and fall to 2 
feet or less areawide.
