NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
333 am CDT Friday Apr 18 2014 


Synopsis... 
surface low pressure is centered over the northern Gulf with a 
warm front extending from the low eastward through the central 
Florida Peninsula and a cold front extending from the low 
southwestward toward the Bay of Campeche. A rather large 
precipitation shield is located to the north and east of the 
surface low. 


Locally...most rain has moved away from the area...but a few 
showers still impacting the MS coastal counties. Temperatures 
generally sitting in the 60 to 65 degree range with dewpoints 
running in the middle to upper 50s. 


&& 


Discussion... 
the surface low over the Gulf should continue to lift to the 
northeast today in response to a fast moving short wave. Latest 
model runs are indicating a greater possibility of isolated to 
scattered showers and thunderstorms this afternoon as the middle 
level trough axis traverses the region. GFS is most aggressive 
with its quantitative precipitation forecast field while the NAM contains the driest solution. The 
Euro is somewhere in between...though closer to the GFS than the 
NAM. Instability will be fairly limited with model soundings 
indicating only meager cape values in the 200 to 600 j/kg range. 
Nonetheless with plenty of moisture in place and the added lift 
associated with the short wave...have gone ahead and bumped probability of precipitation 
up into the slight chance or low end chance category for this 
afternoon and will mention a slight chance of thunder. Coverage 
should be pretty spotty...with quantitative precipitation forecast generally less than one quarter 
inch...though isolated amounts near or above one half inch could 
be possible. 


Short wave exits the area during the late afternoon...and this 
should put an end to any precipitation across the region as high pressure 
builds into the area. With deep ridging forecast to dominate the 
area over the weekend...expect warm/seasonal conditions with no 
real chance of precipitation. Afternoon temperatures should top out in the upper 
70s and lower 80s...and subsidence aloft should keep skies mostly 
clear to partly cloudy. 


Ridging will maintain control of the area on Monday...but will 
begin to break down as another upper trough moves into the 
Mississippi Valley. This trough is expected to send a weak cold 
front toward the area Tuesday...bringing with it the next chance 
of rain. The weak front will be dissipating as it approaches the 
area and it remains to be seen how much shower and thunderstorm 
activity will remain on its southern end. That said...am carrying 
higher probability of precipitation...in the chance category...across northern zones 
compared to southern zones where slight chance probability of precipitation are indicated. 
As the upper trough flattens out and slides eastward...the 
weakening front will continue to dissipate near the coast and deep 
ridging will once again build into the area during the Wednesday 
and Thursday time frame. 


&& 


Aviation... 
mainly MVFR ceilings this morning will give way to VFR conditions 
this afternoon. The VFR conditions will then persist through 
tonight and early Saturday morning. Some light rain may impact the 
kgpt...kasd...kmcb...kmsy and knew terminals this morning...mainly 
early. Otherwise...dry conditions will prevail during the taf 
forecast period. 


&& 


Marine... 
strong northeast to north winds and elevated seas will continue 
today across the coastal waters as an area of low pressure over the 
north central Gulf this morning tracks northeast toward the Florida 
Panhandle during the day. The winds will be strongest across the 
eastern Gulf coastal waters and gradually diminish tonight and early 
Saturday from west to east. Small craft advisories and exercise 
caution headlines will be in effect for most of the coastal 
waters this morning...then gradually be cut back from west to east 
this afternoon and tonight. A ridge of high pressure will rebuild 
over the area during the weekend with offshore flow Saturday 
becoming onshore during the day Sunday and persisting into early 
next week. A weakening cold frontal boundary may approach the 
coast on Tuesday.
