NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
826 am CDT Friday Jul 25 2014 


Update... 
successfull flight this morning. Sounding is very moist with 
precipitable water measured at 1.95 inches. Some slightly drier air from 750mb 
to 650mb then above 600mb. Winds westerly at the surface then northwest 
flow aloft. Entire sounding is slightly warmer than the previous 
sounding by a degree or two. Some parameters from the flight. 500 
mb temperature is -6c...chance of severe very low...level of free convection pressure 
was 868mb... and the freezing level was at 564mb. 


&& 



Previous discussion... /issued 435 am CDT Friday Jul 25 2014/ 


Synopsis... 
latest surface analysis showed a low pressure along the eastern 
Seaboard and Carolinas with a frontal boundary extending southwest 
to central bama to southern Mississippi to central Louisiana to 
central Kansas. North winds were located at Jackson and points 
north and dewpoint readings were generally in the 70s south of 
Greenwood/MS. Latest satellite water vapor imagery showed a 
demarcation line with dry air north from central Georgia to South 
Alabama to btr to lch. Planer view of precipitable water values showed the middle 
layer drying and pool of moisture from coastal Carolinas to 
Mississippi coast to middle Texas coast...with 1.8 to 2.0 inches. 
500 mb temperatures were around -5c along Louisiana coast and -4c over north 
Louisiana and central Mississippi. 18 


Short term... 
light northerly flow in the lower and middle layers will provide 
slight push to the surface boundary into the north parts of the 
forecast area early today. Precipitable water values will decrease to 1.4 inches 
just north of btr and remain elevated around 1.9 inches across the 
river parishes...tidal lakes and Mississippi coast. Surface 
heating with moisture may yield isolated to scattered activity 
along sea breeze fronts and points south this afternoon. At same 
time...warming in the middle layer will result in skinny convective available potential energy late 
this afternoon with values starting around 2000j/kg this morning 
to 700j/kg by this afternoon. Will maintain low end chance probability of precipitation 
for middle day then decreasing coverage by this evening. Warm middle 
layer temperatures Saturday and Sunday will keep convection isolated in 
nature. Upper level high will slide east over Red River valley and 
trough lifting northeast will thickness layers to increase over 
the weekend. As a result...afternoon temperatures may climb into the 
lower and middle 90s. 18 


Long term... 
next week models are consistent on showing an active jet pattern 
and an upper trough that will dig across the the eastern part of 
the country early next week. A cold front will push southward and 
this front should stall over the area Tuesday through Friday. 
Rain chances will increase around the front Monday through Thursday. 
Temperatures across north half may respond down into 60s for morning lows 
Wednesday through Friday. 18 


Aviation... 
primarily VFR conditions will prevail at the terminals through the 
taf forecast period. The exceptions may be a period of MVFR 
conditions at the more fog prone sites during the early morning 
hours today...and also around any convection that may affect the taf 
sites this afternoon. Terminals along and south of a gpt to msy to 
hum line will have the highest probability of rain. 


Meffer 


Marine... 
main Bermuda surface high extends into the Gulf of Mexico with a 
sub-like center being maintained in the eastern Gulf of Mexico today 
through the weekend. This will keep flow generally southwest with 
speeds ranging mainly from around 8-13 knots and seas 2 feet or 
less. A weak summertime cold front will approach the coastal waters 
early next week. At this time it appears the boundary will stall 
across the offshore waters which will causes winds to become 
parallel to the boundary. 


Meffer
