NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1255 am CDT sun Sep 21 2014 


Update... 


Did minor update to weather grids through Monday to remove mention 
of rain where the pop is less than 15 percent. Remainder of the 
forecast is on track for now. 22/dew point 


&& 


Aviation... 


For the 06z tafs...VFR conditions are forecast to prevail with a 
dry airmass in place. Any isolated showers are expected to remain 
mostly offshore/ well south of the coastal airports through 
Sunday night. 22/dew point 


&& 


Previous discussion... /issued 804 PM CDT Sat Sep 20 2014/ 


.Sounding discussion... 


The bulk of the dry air this evening was located above 600mb as 
water vapor imagery shows that the bulk of the dry air has moved 
over the north central Gulf of Mexico. There has been a bit of 
moisture return as precipitable water values are higher compared 
to what was measured this morning. Winds this evening were from 
the northeast at 10 to 20 knots in the low levels and then 
switched to the northwest in the middle levels and north-northwest in 
the upper levels. A peak wind of 57 knots was at 40500 feet above 
the ground. 


00z balloon info: a successful flight that lasted 113 minutes. The 
balloon burst at a height of 20.3 miles above the ground 31.4 
miles downrange south of Chalmette. 


Ansorge 


Previous discussion... /issued 327 PM CDT Sat Sep 20 2014/ 


Short term... 
dry air in place will maintain a period of quiet weather in the 
short-term. Easterly gradient flow will slowly relax tonight. A 
pleasant Sunday in store. 


Long term... 
models appear to be in consensus in bringing cold front into area 
Monday...essentially devoid of moisture until it encounters the 
Gulf Breeze Monday afternoon. This will be the best 
chance...albeit low for rain until at least Thursday. Continental 
dry air moves into the area Post-frontal for Tuesday and Wednesday 
before moderating under easterly flow regime once again. Gulf 
Breeze flow becomes disrupted enough to limit inland extent of any 
convection to the near coastal areas later in the week. 
Temperatures should remain seasonably normal through the period. 
24/rr 


Aviation... 
a drier and more stable airmass is in place across the forecast 
area. As a result...VFR conditions will generally be the rule at 
all of the terminals through the taf forecast period. There is a 
small chance of a shower impacting khum through this afternoon. 
Patchy light fog could briefly result in MVFR conditions late 
tonight and early Sunday morning...09z to 13z...at the more fog 
prone taf sites. 11 


Marine... 
the tight pressure gradient in place across the coastal waters 
resulting from high pressure over the southeast U.S. And weak low 
pressure over the central Gulf of Mexico will gradually weaken 
tonight into Sunday...allowing winds to gradually diminish. The 
Small Craft Advisory in effect for most of the Gulf coastal waters 
through 7 PM today will transition to exercise caution headlines 
that will be in effect until midnight. A cold front will push south 
across the coastal waters late Monday and Monday night which will 
cause offshore to increase to moderate levels. The flow will become 
easterly by middle week and increase in magnitude during the middle and 
week late period as the pressure gradient tightens up once again 
across the north Gulf. 11 


Decision support... 
dss code...green. 
Deployed...none. 
Activation...none. 
Activities...slurry support. 


Decision support services (dss) code legend 
green = no weather impacts that require action 
blue = long fused watch/warning/advisory in effect or high 
visibility event 
yellow = heightened impacts with short fused 
watch/warning/advisory issuances; radar support 
Orange = high impacts - slight to moderate risk severe; nearby 
tropical events; hazmat or other large episodes 
red = full engagement for moderate to high risk severe 
and/or direct tropical threats; events of National 
significance.
