NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
353 am CDT Friday Aug 1 2014 


Short term... 
a quiet radar this morning across southeast Louisiana...however 
that should come to an end at some point this morning as low 
pressure system sits over East Texas. This will stall a front over 
our area and this will give US a good shot of rainfall over the 
next few days. Convection like yesterday morning is struggling to 
get going as the moist air is taking a little bit longer to get in 
here and really help sustain convection. Most of the short range 
mesoscale want to bring in decent convective coverage over the 
western portions of the area later on this morning. Will lean with 
the shorter range models as they were pretty good yesterday. Will 
go with likely probability of precipitation across the western portions of the forecast 
area mainly west of Interstate 55 for today. 


One thing to point out for today and for the rest of the 
weekend...storm motion will be very slow throughout the weekend 
most the time being less than 5 knots. With deeper moisture in 
place and a stalled front expected to be draped over the area we 
will have to watch for some locally heavy rainfall that could 
cause some minor street flooding. This will have to be watched 
throughout the duration of the event. 13/mh 


Long term... 
not much change in the thinking for the rest of the forecast. The 
frontal boundary will be over the area and expect showers and 
thunderstorms everyday this weekend with Sunday looking like it 
could be the wettest day with likely probability of precipitation going in the current 
forecast. Again we will have to keep an eye on the heavy rain 
potential. The rest of the forecast remains pretty much unchanged 
from the previous forecast. The Bermuda ridge will build westward 
across the Gulf of Mexico middle of the week and Onward. This may 
be enough to cutoff moisture flow from the southwest which would 
lower rain chances to 25 percent or less. 13/mh 


&& 


Aviation... 
VFR conditions are expected to prevail all terminals next 24 hours 
though high clouds will be present for much of the period. Scattered 
convection may briefly lower ceilings to around 3kft and visibilities 3-5sm thunderstorms and rain 
mainly between 18z-23z. 24/rr 


&& 


Marine... 
with a weak surface high pressure area hugging the north Gulf Coast...winds 
will remain rather light and seas to remain essentially less than 2 feet. 
A period of increased swell period and an established swell train may 
develop by middle of next week with steady state flow through the Florida 
Straits and the Yucatan Channel possibly coupled with some enhancement from 
T.S. Bertha once aligned abeam of the Florida Straits. 24/rr

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