NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
739 am CST Friday Feb 12 2016 


..sounding discussion... 


Overall the sounding is fairly dry with a precipitable water value of 0.54 
inches but there are still a few interesting features. The profile 
is fully saturated through the first 500 feet and continues with relative humidity 
values of >90% to the inversion layer at 940 mb (2300 ft). Above 
the inversion the sounding is dry with relative humidity values <20%. Winds are 
still backing slightly through the profile from west-southwest near the 
surface to northwest further aloft. Ll wind speeds are 20-30 kts which 
will help dissipate any early morning fog and with the dry air 
aloft we will be seeing another day of clear skies.

Previous discussion... /issued 331 am CST Friday Feb 12 2016/ 


Short term...it has been another quiet night across the region 
but temperatures are much warmer than previous nights. Patchy fog or low 
clouds are trying to develop over the area. 


No big changes in the short term. The clipper system moving across 
the Great Lakes tonight and into the Delaware-Maryland-Virginia region reinforcing the 
northwest flow aloft while also driving a backdoor cold front through the 
region overnight tonight/early Sat. This will be another dry front. 
The region will see a decent cool down with this front as h925 temperatures 
drop to around 5-7c which is about 6-7c degrees cooler than today. 


Heading into sun we will begin to see the pattern break down with 
the middle levels becoming zonal. At the surface high pressure which will 
dominate the region Sat night will shift east centering over the 
Atlantic Seaboard. This will lead to srly flow allowing moisture to 
return ahead of our next system on Monday which will be diving southeast 
across the Continental Divide late sun. Temperatures will moderate a little 
on sun generally be about 5 degrees warmer than Sat. As for lows Sun 
morning...it will be quite cool. High pressure will still be 
dominating the region as of Sun morning and dewpoints will be in the 
20s. Light winds...clear skies...and dry conditions could lead to a 
light freeze over a few locations. /Cab/ 


Long term...model consistency and continuity continue to be rather 
good. Confidence continues to grow with respect to rain chances Monday 
and a quiet forecast for the remainder of the work week. The biggest 
difference b/T the GFS and European model (ecmwf) in the extended portion of the forecast 
is with respect to temperatures for the second of the work week but that is 
about it. 


The time frame with the greatest impact in the forecast will be Monday. The 
main protagonist will be a strong Pacific northwest short wave which will continue to 
sharpen as it moves into the Southern Plains and lower MS valley Monday. 
This short wave will continue to deepen as it moves across the lower MS 
valley causing 500 mb hght falls of 12-13dm through the day Monday. In 
response to the short wave a surface low will begin to take shape over the 
arklamiss overnight sun. The surface low will deepen and track east 
through the lower MS valley Monday driving a cold front through the 
area. Ahead of this system moisture will finally increase with precipitable waters  
expected to be above 1". The rather impressive hghts falls combining 
with the cold front and increase in moisture should have little 
problem leading to widespread rain showers during the day Monday. As for 
thunderstorms and rain...still expect a few embedded thunderstorms and rain as there will be marginal 
instability to work with combining with a middle level jet approaching 
100kts punching into the region. 


Both the short wave and surface low will push out Monday night with cooler and 
drier air moving back in but this will be only temporarily. The 
pattern will be progressive with northwest flow over the region Tuesday 
breaking down over the week and a ridge moving over the area 
Thu/Fri. Ll temperatures will quickly moderate after Tuesday with temperatures near to 
slightly above normal along with dry conditions expected. /Cab/ 


Aviation... some shallow radiational fog was developing at kmcb 
and spreading south to affect kbtr-khdc-kasd before 12z. IFR ceilings 
and visibility should improve to VFR ceiling and visibility OK by 1430z...then convective 
cloud bases at low end VFR during the afternoon. Frontal passage 
expected through all terminals from north to south this evening with 
north winds before 13/09z. 24/rr 


Marine... moderate westerly flow between weakening high over 
central Gulf and Arctic frontal zone near I-20 corridor. This front 
will be entering north Gulf overnight and move south of the coastal 
waters before daybreak Saturday. North winds will increase in 
response to strong cold air advection for Small Craft Advisory 
conditions anticipated Saturday morning but settle to below criteria 
by late afternoon. Much stronger clipper front moves through coastal 
waters Monday night with Small Craft Advisory conditions once again. 
24/rr 


Decision support... 
dss code....blue. 
Deployed...none. 
Activation...none. 
Activities...river flooding continues on the Pearl River.
