NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
321 PM CST Monday Feb 8 2016 


Short term... 


A strong upper level trough embedded within deep layer northwest 
flow is currently moving across the Gulf south. A very tight 
pressure gradient associated with this trough of low pressure is 
in place across the region...and this has resulted in very strong 
winds of 20 to 30 miles per hour with gusts over 40 miles per hour at times. These 
strong winds should dissipate over inland zones this evening as 
temperatures cool and overall mixing of the boundary layer 
decreases. However...for areas along the immediate coast and south 
of the tidal lakes...strong northwest winds will persist through 
the overnight hours. This will be due to continued thermal mixing 
occurring through the night as cold air moves over the warmer 
nearshore and lake waters. Thus...the Wind Advisory will remain in 
effect through tomorrow morning for areas south of Lake 
Pontchartrain including most of metropolitan New Orleans. 


These strong northwest winds will bring a much colder airmass into 
the area...and overnight lows should easily fall into the upper 
20s and lower 30s over inland locations and the middle 30s along 
the coast. Wind chills will fall into the 20s across the entire 
forecast area. Heading into tomorrow...The Heart of the 925mb cold 
pool will be over the region...and daytime highs will struggle to 
reach into the lower 50s even with abundant sunshine. Another cold 
night will be on tap tomorrow night...with lows once again falling 
into the 20s and 30s across the area. Fortunately...winds will be 
somewhat lighter...so wind chills will be far less extreme. 


The surface high will be firmly centered over the area on 
Wednesday...and expect to see sunny skies and cool temperatures 
remain in place. Daytime highs should rise into the middle 
50s Wednesday afternoon. Heading into Wednesday night...the 
surface ridge is expected to slide east of the area...allowing for 
onshore flow to develop. This onshore flow will allow for some 
weak moisture and warm air advection to occur and expect overnight 
lows to be about 10 degrees warmer. 


Long term... 


Although deep layer northwest flow will remain in place in the middle 
and upper levels through the upcoming weekend...increasing 
southwest flow in the low levels should allow for a quick warm up 
in daytime highs. Temperatures should quickly climb into the upper 
60s and lower 70s both Thursday and Friday. The warm up will be 
aided by increasing weak negative vorticity advection and 
subsidence aloft...ample solar insolation from clear skies...and a 
fairly dry airmass throughout the atmospheric column. There should 
be a decent diurnal range from 25 to 30 degrees...with overnight 
lows cooling into the 40s Thursday and Friday nights. 


A back door cold front should slide in from the northeast on 
Saturday as the parent clipper system pulls through the northeast 
Continental U.S.. this front should be moisture starved...and only expect 
to see some clouds move in as the front approaches. Winds will 
shift back to the northeast in the wake of the front...and weak 
cold air advection will take hold. Temperatures should be around 
10 degrees colder both in terms of daytime highs and overnight 
lows on Saturday and Sunday. 


Another fast moving upper level trough will slide through the 
midwestern states on Monday. This system will bring another cold 
front into the area next Monday. There is some disagreement in the 
models in exactly how much middle and upper level moisture this 
feature will have to work with. Given the uncertainty on rain 
chances have went with slight chance probability of precipitation for Monday at this time. 


&& 


Aviation... 


VFR through the forecast period. The only issue in the period will 
be the winds. They will be elevated and gusting well over 25 knots 
this afternoon and evening at all taf sites. Winds should subside 
some over the northern taf sites and should not be as gusty after 
sunset. The sites south of Lake Pontchartrain will remain gusty a 
little bit longer. Winds overnight should be in the 15 to 20 knot 
range to the south and the 8 to 12 knot range to the north. Expect 
more of the same issues for tomorrow as winds will pick back up as 
mixing kicks in with sunrise. Winds are expected to be in the 15 to 
20 knot range again on Tuesday. 13/mh 


&& 


Marine... 


Strong gradient flow will continue to impact the coastal waters 
through tomorrow evening before finally beginning to ease tomorrow 
night and Wednesday. Gale conditions will persist for most of the 
waters...with high end small craft conditions expected over the 
Mississippi Sound and tidal lakes. Wind gusts in excess of 35 
knots will be possible over these nearshore waters. In the open 
Gulf waters...wind gusts of around 45 knots and seas of up to 
14 feet can be expected through tomorrow morning. As a surface 
high becomes more centered over the area on Wednesday and 
Thursday...winds will gradually veer from the north and northeast 
to the southeast and then southwest. Wind speeds will typically be 
in the 10 to 15 knot range and seas should fall to 4 feet or less. 
A slight increase in the southwest flow is expected on Friday in 
advance of an approaching front. Winds could rise into the 15 to 
20 knot range over the eastern waters during this period. A cold 
front should then slide in from the northeast on 
Saturday...shifting winds back to the northeast and also bringing 
exercise caution conditions to most of the waters. Small Craft 
Advisory conditions may develop by Saturday night.
