NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
818 am CDT sun Apr 19 2015 


..sounding discussion... 
The sounding this morning is looking a bit different from the past 
week as a new airmass is finally beginning to move into the area. 
Moisture is still high at low levels with 60 f dewpoints up to 925 
mb but becoming shallow. Much drier air is aloft resulting in an 
overall precipitable water at 1.32 inches... which is lower than what has been 
observed lately but still above average. The profile is unstable 
with 1200 j/kg mixed layer cape and 1850 j/kg mu cape. Middle level 
lapse rates have steepened significantly to 6.5 to 7 c/km as the 
upper low approached overnight. There is an interesting shear 
profile with the base of the upper trough nearby. Winds are SW 
from the surface to 500 mb then become south-southwest and increase in speed to a 
110 knots jet maximum at 220 mb. Despite drying air at low levels and 
better forcing to the north of the area... any storms that can 
form later today could become severe.

Previous discussion... /issued 528 am CDT sun Apr 19 2015/ 


Short term /today through Tuesday night/... 


Although there will be fewer showers and thunderstorms over land 
areas today...the thunderstorms that are around will have to be 
closely monitored for potential severe weather...especially this 
evening across mainly north and northwest portions of the area. 
More numerous thunderstorms...many appearing strong to 
severe...were occurring over much of the coastal waters early this 
morning...and these are likely to persist through much of the 
morning before moving east by around midday as associated upper 
shortwave trough and divergence maximum moves east. Higher 
precipitable water values over over 1.75 inches are also 
associated with this area of numerous thunderstorms offshore...but 
the models also flush out this moisture to the east during the 
morning hours. Precipitable water values are then only expected to 
range from around 1 inch to maybe near 1.2 inches in pockets as 
the cold front approaches this evening. Isolated to scattered 
showers and thunderstorms are expected over land areas this 
morning...then this afternoon looks mostly dry as we await the 
main shortwave trough axis and cold frontal passage tonight. Will 
still be carrying a slight chance of showers and thunderstorms 
across all areas this afternoon since instability is expected to 
moderate to high during peak heating...and a few strong to severe 
thunderstorms will be possible. 


The highest potential for severe thunderstorms is expected to be 
this evening to the north of the I-10/12 corridor as there will 
be leftover moderate to high instability interacting with better 
forcing from upper divergence and low level convergence with the 
approaching cold front. The main severe weather threats will be 
damaging winds and large hail...however an isolated tornado or two 
cannot be ruled out. A few showers and thunderstorms could linger 
overnight before ending by daybreak as the long anticipated cold 
front finally sweeps through. 


A much needed period of drier weather with no chance of rain and 
slightly cooler /more so at night/ and less humid conditions is 
expected Monday through Tuesday night. Monday should see plenty of 
sun...but some high clouds are expected Monday night into Tuesday 
resulting in partly cloudy skies. Highs on Monday and Tuesday are 
expected to reach the upper 70s to near 80...however the lows on 
Monday and Tuesday nights are expected to drop into the 50s to 
lower 60s. 


Long term /Wednesday through Saturday night/... 


Unfortunately...rain chances return for this entire 
period...although it is not expected to be nearly as wet as the 
last week to 10 days. Surface high pressure will shift east 
Wednesday which will bring a return of low level southerly winds 
and Gulf moisture. The forecast area will be near the eastern side 
of a shortwave ridge aloft while areas to our northeast will be in 
northwest flow with disturbances moving through in the Wednesday 
through Thursday time frame. This will also likely push a slow 
moving cold front into the deep south. Later in the week...the 
shortwave ridge aloft may move right over to just east of the 
forecast area while flattening out as disturbances start to move 
out of the Baja California Mexico region. The models have some differences 
and difficulties in handling the timing and position of these 
minor systems...and it is hard to time the wetter periods with 
confidence. Right now...a blend of the GFS and European model (ecmwf) indicate 
higher rain chances on Thursday and especially Friday before a 
possible drying trend on Saturday. Temperatures are expected to be 
warm and above the seasonal normals through the period. 22/dew point 


Aviation... 


IFR ceilings running between 800 and 1000 feet have developed in the 
last hour. Have included a tempo group to reflect these conditions 
through around 12-13z. The low level inversion will quickly lift 
after 13z...allowing any ceilings and potential fog to burn off. 
Once the inversion lifts...drier air advecting into the middle-levels 
of the atmosphere will quickly mix down. Overall...expect VFR 
conditions with a scattered deck of clouds around 2000 to 4000 feet 
through 00z. There could be some patchy fog formation early 
tomorrow morning around daybreak. Kmcb and khum could see a brief 
period of IFR visibility restrictions if the fog forms. 32 


Marine... 


A slight increase in gradient flow from the southwest will impact 
the eastern legs of the coastal waters today into early tonight. 
Small craft exercise caution conditions can be expected during this 
period over the eastern waters. Winds will then veer to the 
northwest and north tomorrow in the wake of a passing cold front. 
This offshore flow of around 15 knots will continue into 
Tuesday...with some continued veering of the winds to the east by 
Tuesday evening. Overall...seas will generally range from 3 to 5 
feet during this period. As high pressure becomes centered to the 
east of the area for Wednesday and Thursday...winds will take on a 
south-southeast component and weaken to between 10 and 15 knots. 
Seas will fall back to around 2 to 3 feet as this occurs. 32
