NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
803 am CDT Sat Oct 25 2014 


..sounding discussion... 


Strong surface inversion of 10c this morning will mix out by middle- 
morning as surface heating and boundary layer mixing takes place. 
There is also a weaker inversion between 840 and 790 mb. Winds 
throughout the column are from a northerly direction due to high 
pressure just off to the west. This has allowed drier air back 
into the region...but that is not to say that we had a lot of 
moisture in the first place. A maximum wind speed of 68 knots was 
located at 42900 feet. 


12z balloon info: this morning/S flight lasted 95 minutes and 
attained a height of 20.2 miles above the ground before bursting. The 
balloon terminated over the South Shore of Lake Borgne 34 miles 
downrange.

Previous discussion... /issued 424 am CDT Sat Oct 25 2014/ 


Short term... 
perfect fall conditions will continue across the forecast area today 
with high pressure in place and light northerly flow. The air mass 
will modify a little...bringing highs slightly above climatological 
normals. Mav was right on spot for forecast high temperatures on Friday. 
Therefore have bumped up previous maximum temperatures to mav guidance. So 
expecting clear skies and highs in the lower to middle 80s for the day. 
The warming trend will continue into Sunday as upper level ridge 
builds in from the west. Probably half or more of the County Warning Area will be 
above 85 degrees by early afternoon. Monday should simply be a 
repeat of Sat/sun as the upper high tracks east across the Gulf 
Coast. 


Long term... 
Dare I say rain chances may be coming back? Well...at least the 
probability will be there. Upper and surface highs sliding east early 
this week will allow for southeast flow to return and bring moisture 
levels back up. This in combination will falling pressure induced by 
an approaching trough may trigger a few showers beginning Tuesday. 
The threat for showers and a few thunderstorms will continue into 
Wednesday as a weak frontal boundary slowly moves in from the north. 
Upper trough is expected to be well to the north and racing east 
which will cause it to stall and somewhat dissipate until a 
reinforcing stronger front sweeps through towards the end of the 
week. 


Meffer 


Aviation... 
VFR conditions with clear skies and excellent visibilities will prevail 
through early Sunday morning. 18 


Marine... 
a 1020mb high from central Texas coast to northern Louisiana will 
slowly sag southeast through today. The pressure gradient has 
relaxed over land and near the coast. However...a slight pressure 
gradient over north central Gulf will maintain a northeast flow of 
10 to 15 knots over the open coastal waters through tonight. The 
high will shift toward the eastern Seaboard by late Sunday...which 
will allow winds to shift to the east and then southeast by Sunday 
night. Winds will generally be near 10 knots and seas will range 
from 1 to 3 feet early next week. A cold front is expected to push 
through the coastal waters Thursday. 18

Deployed...none.
