NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
741 am CST Thursday Jan 29 2015 


..sounding discussion... 


Large temperature inversion of 9 degrees fahrenheit from the 
surface to about 600 feet that will mix out by midday. Air remains 
a bit drier than normal for this time of year with a precipitable 
water of 0.56 inches. While winds were calm at the surface...they 
were from the south-southwest just above the inversion. Winds are 
then from the southwest to about 3500 feet...then mainly from the 
west up to about 22500 feet and then from the northwest. 


12z balloon info: no issues with the morning flight that lasted 
102 minutes and burst southeast of Cat Island over the Gulf of 
Mexico at a height of 20.2 miles above the ground 48 miles 
downrange from the office.

Previous discussion... /issued 331 am CST Thursday Jan 29 2015/ 


Short term...quiet cool night again with just some high clouds 
early this evening. Temperatures had dropped into the 40s to lower 
50s across the entire County Warning Area by 8z. 


Not much in the way of impacts through the first 48 hours. Weak northwest 
flow currently over the region will become slightly more established 
as a northern stream short wave drops through the Great Lakes and the middle MS 
valley and twrds the Ohio/Tennessee valleys. This will drive a cold front 
into the region tonight but ahead of it look for a warm day. H925 
temperatures of 12-14c suggest highs could be in the middle 70s in a few 
areas. 


Tonight as the front moves through cooler and drier air will slide 
in. In addition dont expect any rain as moisture will be rather 
limited. H925 temperatures will drop down to 6-8c which could mean as much 
as a 15 to almost 20 degrees cooler for a high on Friday. 


Friday night we will begin to move under a ridge while a large closed 
low deepens over the Baja California. As we head into the weekend this low will 
only move slightly south and still be over the Baja California by Sun morning. 
At the same time another northern stream short wave will drop southeast across the 
Continental Divide and into the plains. This will flatten the ridge 
and the combination of that and the closed low over the Baja California will put 
US under weak SW flow. In addition on sun a weak surface low may develop 
over the region and this will lead to a return of rain sun. Will not 
mention thunderstorms and rain as there will be no instability to work with. /Cab/ 


Long term...overall the medium range models are not in terrible 
agreement. The closed low over the Baja California will still take some time 
before it finally opens up and lifts out. Will stick with a blend of 
the models. 


Sun night our little surface wave/low should quickly pull out to the NE 
with a re-enforcing cold front moving through the region. Rain will 
continue overnight sun but should quickly come to an end before 
sunrise Monday as our cold front sweeps through. Another cold dry 
airmass will then slide south into the region and this will dominate 
the region for the next few days until the closed low finally gets 
kicked out of the Baja California. There are some timing differences between 
the models as to when this will eventually occur with the GFS the 
fastest on Tuesday and the Euro holding off more twrds Wednesday. Once this 
occurs we will likely see a return of rain possibly as early as late 
Tuesday night but more likely on Wednesday. /Cab/ 


Aviation... 
patchy fog is showing up at isolated locations this morning. A few 
terminals west of hdc could see a few hours of visible restrictions with 
IFR conditions. Otherwise...VFR conditions will generally prevail 
through the taf forecast period. A cold front will be moving through 
the area tonight which will bring a wind shift and gusty winds at 
sunrise. 


Meffer 


Marine... 
winds have been steady veering from east-northeast to south-southeast since sunset 
yesterday in response to surface ridge that was centered north of the 
area...shifting east. An upper level trough diving southeast out of 
Canada and across the Great Lakes region will send a cold front 
towards the area today. Frontal passage over the coastal waters not 
expected late tonight/early Friday morning. Have updated the zones 
to have exercise caution headline starting at 08z tonight as winds 
Jump Up to 15-20 knots. For now have the headline dropping off by 
noon Friday but elevated winds could linger through Friday evening 
and overnight as the Post frontal ridge remains well to the north. 
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. A more substantial cold front looks to be coming in 
late Sunday night into Monday morning which should bring small craft 
conditions to the area. 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.
