NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
349 PM CDT Friday Mar 27 2015 


Discussion... 
gorgeous weather will continue into the first part of this 
weekend as cool and dry high pressure settles over the area. Lows 
tonight will generally be 5 to 10 degrees below normal depending 
on location...ranging from the lower 40s north to the lower 50s 
near the Louisiana coast. Think guidance is a bit too cool with 
regards to highs tomorrow. Cold air advection will have ceased 
or at least weakened significant with winds forecast to become 
more easterly. Add in full sunshine with a Rising Sun angle...and 
think most locations will reach the 70 degree mark instead of 
topping out in the middle to upper 60s as guidance suggests. Thus am 
carrying temperatures a few degrees higher than guidance with forecast 
afternoon temperatures generally in the lower 70s. 


High pressure shifts eastward on Sunday and warming trend begins 
as winds become southeasterly. Expect near normal temperatures on 
Sunday...rising above normal on Monday. 


A cold front dropping into the lower Mississippi Valley still 
looks to stall before reaching the coast as it loses its upper 
level push and flow becomes more westerly. The stalling boundary 
could still bring a chance of showers to the northern half of the 
area Monday and Tuesday...and this is reflected in the forecast. 


Though there are differences in timing...both the GFS and Euro 
indicate a southern stream shortwave will bring scattered to 
numerous showers and thunderstorms to the area midweek. Will 
continue to carry somewhat of a blend of available guidance for 
this system as either scenario seems plausible. This results in 
solid chance probability of precipitation for both Wednesday and Thursday...but it is more 
likely that one of these two days will see numerous showers and 
thunderstorms while the other will see only isolated to possibly 
scattered convection. Will need to continue refining this portion 
of the forecast as the situation becomes clearer. 


Beyond midweek...another front could pass through the area for the 
start of next weekend...but there is some question as to how 
strong it will be by the time it gets here. 


&& 


Aviation... 
expect VFR conditions to prevail through the forecast period. 
Winds will remain slightly elevated through 0z at all terminals. 
Winds will decrease overnight at all terminals with the exception 
of knew where winds will still be elevated through the night. 
Expect VFR conditions for Saturday. 


&& 


Marine... 
high pressure will move into the coastal waters. Winds will be 
elevated through the evening hours and small craft exercise 
caution conditions will still remain in the outer waters through 
tonight. Winds will rotate back around to onshore through the 
weekend as the ridge slides east. Winds not likely to change much 
through the middle of next week with high pressure generally 
remain situated east of the area.
