Area forecast discussion 
National Weather Service New Orleans la 
650 am CST Monday Dec 22 2014 


..sounding discussion... 


Warm and moist characterizes the lower part of the atmosphere 
this morning. Temperatures are about 4 to 5 degrees higher 
/warmer/ in the lowest 5000 feet than yesterday at this time. 
Below 8500 feet...the atmosphere is nearly saturated and the 
precipitable water value in the entire column has increased to 
almost 1.25 inches. Fog/mist was also observed at launch time also 
confirming the moist low levels. While not impressive...the lifted 
index is negative at 0.3. A veering wind profile was noted with 
southeast winds at the surface shifting to the southwest around 
5000 feet. A maximum wind speed of 124 knots was located at 35500 
feet. 


12z balloon info: no issues with our flight this morning. A height 
of 19.8 miles was attained before the balloon burst near Lucedale MS 
93 miles downrange from the office. The flight lasted 98 minutes.

Previous discussion... /issued 331 am CST Monday Dec 22 2014/ 


Short term... 


Areas of fog will persist over the area through the first half of 
the morning. As boundary layer flow begins to increase there will 
be enough overall mixing in place to allow the fog to clear. The 
rain currently along the immediate Louisiana coast and over the 
offshore waters should diminish as overall Omega aloft decreases 
in the wake of a departing vorticity lobe. Do not expect to see the 
showers persist over the immediate Louisiana coast after middle- 
morning...except for areas in the immediate vicinity of Head of 
Passes in lower Plaquemines Parish. Southerly flow will develop 
and intensify through the day. Although mostly cloudy to overcast 
conditions are expected to persist...there should be a surge of 
warmth and moisture into the region that will push temperatures in 
the upper 60s and lower 70s by the afternoon hours. 


Tonight...an upper level trough centered over the plains 
will begin to rapidly deepen. This rapid deepening will be driven by 
some strong northern stream vorticity descending down The Spine of 
The Rockies. An attendant upper level jet in in excess of 120 
knots will accompany this northern stream feature as it dives into 
Texas. As this jet rounds the base of the trough...it will begin 
to take on a more neutral tilt and also start to lift to the 
northeast. As the jet streak rounds the base of the trough...low 
level cyclogenesis will begin in eastern Texas. Warm frontogenesis 
will take place across the forecast area tonight...and the 
combination of a developing jet couplet aloft along with 
increasing isentropic forcing in the low levels will bring 
increasing rain chances to the entire forecast area. Expect to 
see rainfall develop in the late evening hours and become more 
likely as the night proceeds. Model soundings continue to show 
a stable layer in the low levels...but there will be a region 
elevated cape values above this stable layer. Expect to see 
scattered showers and isolated thunderstorms begin to develop 
during the late evening hours and overspread the entire area 
through the remainder of the night. Lapse rates aloft combined 
with increasing Omega support the development of some stronger 
storms after midnight. Given that these thunderstorms will be 
elevated above the stable layer...hail will be primary threat late 
tonight. 


Tuesday still looks to be a very active day...with the risk of 
some severe thunderstorms forming during the afternoon and evening 
hours. The region will remain centered beneath a jet couplet and 
overall upper level forcing will be very strong. Overall 
instability will increase through the day...with cape values 
expected to rise to around 1000 j/kg during the afternoon and 
evening hours. Shear values will also be fairly impressive with 
0-3 km shear of around 30 knots and helicity values ranging from 
150 to 250 m2/s2 in the afternoon and evening hours. Given these 
parameters...all convective modes will be possible with this 
system Tuesday into Tuesday evening. Most of the convection will 
likely be pre-frontal...with the main wind shift and surge of 
colder air generally coming in Tuesday evening over western zones 
and during the overnight hours for eastern zones. Conditions will 
clear from west to east with this frontal passage...and expect to 
see lingering convection and a threat for isolated severe 
thunderstorm activity over the coastal Mississippi zones through 
late Tuesday evening. 


The upper level trough axis will pass through the area Wednesday 
and Wednesday night. The Heart of the cold pool will also pass 
over the area during this time frame. 1000-500mb thicknesses will 
plunge to around 5430 meters and 925mb temperatures will drop to 
around 0 degrees celsius by Wednesday afternoon. This correlates 
to a surface temperature in the lower 50s. With clear skies in 
place Wednesday night...readings will easily cool into the 30s 
over most areas. A light freeze may occur over parts of southwest 
Mississippi and the Northshore late Wednesday night. Conditions 
will also be very breezy as the trough axis moves through Wednesday 
into Wednesday night. 


Long term... 


The trough axis will finally begin to pull east of the area on 
Thursday...with strong subsidence and very dry air taking hold of 
the area. Sunny skies and cooler than normal temperatures can be 
expected. Daytime highs will only climb into the middle to upper 
50s and lows on Thursday night will drop back into the lower 40s 
over inland locations as conditions radiate out. 


Both the Euro and the GFS indicate that another short wave trough 
will slide through the area for Friday and Saturday. The Euro has 
a sharper trough slide through the area...and thus Sparks off more 
rainfall over the area. The GFS has a shallower trough that brings 
increasing clouds...but lower overall probability of precipitation to the region for 
Friday and Saturday. On Sunday...the weaker GFS also keeps a 
boundary along the immediate coast with higher probability of precipitation and more cloud 
cover. The Euro has a much stronger front push offshore with 
clearing skies and dry weather taking hold. Given these large 
model differences...and overall low confidence in weekend 
forecast...have went with a blend of these solutions. This 
solution brings a chance of rain to the area beginning Friday 
night and continuing into Saturday and Saturday night as the 
trough axis and frontal boundary move through the area. Have not 
introduced thunder into the forecast at this time...although the 
Euro solution would support some thunderstorm development. 
Temperatures will generally be near normal for Friday and 
Saturday. On Sunday...have only a slight chance of rain in the 
forecast given the large model discrepancies noted earlier. 


Aviation... 


Shallow marine layer only about 250 feet deep will maintain IFR ceilings 
and MVFR visibility around 1sm br through around 15z before improving to 
prevailing MVFR ceilings remainder of taf period. Some spotty shower 
activity possible from 22/12z-23/12z though khum may be close enough 
to detect distant thunder well south of that location later Monday 
night. 24/rr 


Marine... 


Gradual warm frontogenesis process underway in the north Gulf will 
maintain generally light to moderate easterly flow that will veer to 
more onshore orientation as warm front lifts north later today. 
Winds should then begin to respond to synoptic scale frontal system 
developing in the plains states with deeper fetch into the Gulf to 
increase winds to low end Small Craft Advisory levels Tuesday. Hard 
wind shift still looks to be on track for late Tuesday night into 
Wednesday morning with high end Small Craft Advisory winds and seas 
developing along with some gale force gustiness at peak cold air 
advection time-frame Wednesday morning. Squall line convection on 
the coastal waters late Tuesday evening will likely prompt 
short-fused marine warning issuances during that time-frame. Severe 
weather potential should move east of MS coastal waters by daybreak 
Wednesday. 24/rr 


Decision support...

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
