NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
705 am CST Friday Jan 30 2015 


..sounding discussion... 


Elevated temperature inversion of 6 degrees celsius begins around 
1500 feet on this morning's sounding. The column is rather 
dry...though it is a bit more moist between 20000 and 29000 
feet. Infrared imagery shows patches of clouds trying to move into our 
area and this may be the height that they are located. Winds from 
the surface to 4000 feet were from the northeast or north...then 
from the northwest or west-northwest through the remainder of the 
atmosphere. A peak wind speed of 93 knots was located near 40400 
feet. 


12z balloon info: no issues with the 115 minute flight this morning 
that traveled 78 miles downrange from the office and burst at a 
height of 21 miles above the ground east of Breton National 
Wildlife Refuge over the Gulf of Mexico.

Previous discussion... /issued 406 am CST Friday Jan 30 2015/ 


Short term...our first cold front is already pushing through the 
County Warning Area with winds quickly shifting out of the north and northwest overnight. Temperatures 
have fallen nicely behind it with as much as 10-15 degrees in about 
3 hours. One thing to note...most if not all sites have likely seen 
their high temperature for the day already as everyone at 6z were in the 
upper 50s to lower 60s. 


Look for a mostly quiet forecast for the next 36-42 hours. Newly 
established northwest flow will dominate today but our airmass will not get 
as much of a southern push and actually start to nudge east late in the 
day. H925 temperatures will drop to around 6-8c today leading to a rather 
cold day with daytime highs in the middle 50s to near 60. Again the 
official high for the calendar day has likely already occurred just 
about everywhere in the County Warning Area. Temperatures will be slow to warm as cold air advection will 
likely continue through the day but given what should be mostly 
sunny skies surface temperatures will likely still warm about 5-10 degrees. 
This will feel cold with respect to yesterday as we will be 
about 15-20 degrees cooler than yesterday. 


Tonight as ridging aloft starts to occur and our surface high pushes 
into Appalachia and eventually twrds the middle and southeastern Atlantic coast 
ll temperatures will start to slowly rebound. Moisture will also slowly 
recover. The bulk of the changes though will occur Sat night and 
more so on sun and into Sun night. A deep closed low currently 
digging into the Baja California will slowly nudge twrds Mexico Sat night 
before digging once again twrds the southern Baja California Sun night. This along 
with another northern stream short wave will break the ridge down sun. Moisture 
will increase across the region and as this northern stream short wave drops southeast 
across the northern plains and into the middle MS valley it will send 
another cold front twrds the region. This front...increasing 
moisture...lowering hghts in the middle levels along with tapping into 
the subtropical jet should provide more than ample support for num 
rain showers sun. There is even a small window for a few thunderstorms and rain Sun afternoon as 
there will be a little elevated instability and the rrq of the jet 
to work with. 


Rain will continue into the evening sun but we should see it slowly 
taper off from northwest to southeast overnight as our cold front moves through 
the region. /Cab/ 


Long term...some uncertainty in the long range forecast as the Euro and 
GFS have pretty large strength and timing issues beginning overnight 
Tuesday. Euro has had the largest shift from last nights run but is 
quite similar to yesterdays 12z run. The GFS has been the more 
consistent model timing wise but is weaker than last nights run. 
With the uncertainty will stick with a blend of the models with a 
slight lean to twrds the GFS which has support from its MOS along 
with the gfes and Gem. The Euro at this time appears to be the 
outlier cold model but will closely watch to see where the models 
trend. 


Eastern Continental U.S. Trough becomes reestablished Sun night and will send our 
second cold front and airmass into the area Monday. This will keep US 
cool and dry through Monday night but the cold front that moved through 
Sun night will stall over the Gulf. This old frontal zone will 
become activated as the old closed low over the Baja California is finally 
lifting out across Mexico and into Texas leading to cyclogenesis in the 
southwestern Gulf Tuesday. As the disturbance lifts into Texas Tuesday night it will 
open up and put the region under SW flow aloft. The developing surface 
low will continue to deepen and start lifting to the NE twrds our 
County Warning Area. This will increase the rain chances Wednesday. As previous fcster 
mentioned we are still on the cold wet side of the system so not 
anticipating much if any thunderstorms and rain. 


Third re-enforcing cold front will move in for the latter half of 
the week. Colder and drier airmass will move in behind this surface low 
but there are questions to how cold this airmass will be. The Euro 
has shifted significantly cooler than last night but is also at odds 
with its own MOS which is significantly warmer than the raw model. The 
GFS has been more consistent so as mentioned earlier will use a 
blend with a lean twrds the GFS. /Cab/ 


Aviation... 
a dry cold front is currently moving through the area...now south of 
msy and should be approaching hum shortly. VFR conditions will 
generally prevail at the terminals through the taf forecast period. 
Gusty north winds will be observed downwind of Lake Pontchartrain at 
knew and kmsy after frontal passage through the morning hours. 


Meffer 


Marine... 
latest observations show that cold front is currently just south of 
Lake Pontchartrain and the Mississippi Sound...steadily progressing 
southward. So will go ahead and start previously issued Small Craft 
Advisory and exercise caution headline as wind speeds should ramping 
up quickly. Small craft condition duration will be quite short... 
ending by around noon as the pressure gradient quickly begins to 
weaken. Only other change made to the forecast today is adding 
exercise caution headline for this afternoon for offshore waters. 


A repeat of winds rotating back around to onshore by late Saturday 
is expected as progressive pattern keeps the ridge to the north 
moving east towards the Atlantic coast. A more substantial cold 
front still looks to be coming in by 12z Monday morning. It should 
bring small craft conditions to the area with a brief period of 
winds sustained in the upper 20s and a few gusts above 30 knots 
between midnight and 6am. A Small Craft Advisory will likely be needed but improving 
conditions in the afternoon should keep duration once again fairly 
limited. East to northeast flow will remain in place through the 
middle of next week as high pressure builds in from the north and 
then northeast. Speeds will stay elevated as a surface low develops 
in the western Gulf and tracks east across the northern Gulf. 
Exercise caution at the least can be expected as it nears the 
coastal waters.
