NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1050 PM CDT Monday may 25 2015 


Update... 
a squall line is currently racing east across central and 
southwest Louisiana at around 45 miles per hour. This line should reach the 
far western zones of the County Warning Area in the next hour or 2 and progress 
eastward. The main threats will be strong and damaging winds along 
with torrential rainfall and isolated tornadoes. Thus a Tornado 
Watch has been issued for the entire County Warning Area through 5am. 


&& 


Previous discussion... /issued 338 PM CDT Monday may 25 2015/ 


Short term... 


A trough currently over the Southern Plains will continue to bring 
higher than normal rain chances to the region through Wednesday 
before the trough axis finally exits the region. 


Initially...a elongated area of increased vorticity stretching 
over the eastern half of the forecast area will serve as a focus 
for continued shower and thunderstorm through the evening hours 
today. High precipitable water values of around 1.7 inches and favorable lapse 
rates of around 7c/km will allow for continued to convection 
through the evening hours. The convective coverage should begin to 
wane a bit during the evening hours with the loss of daytime 
heating and lower cape values. 


Heading into tomorrow...another surge of increased vorticity and 
Omega currently over Texas will eject into the lower 
Mississippi Valley. This will be the main axis of the parent 
upper level trough lifting out of the Southern Plains. With ample 
forcing in place aloft...and a surge of deeper moisture 
translating along with the trough...expect to see numerous showers 
and thunderstorms develop through the day. The strongest dynamics 
will remain north of the area...so organized deep convection will 
be less of a concern. However...locally heavy downpours...gusty 
winds to around 40 miles per hour...and frequent lightning strikes will be a 
concern with the thunderstorms tomorrow. The highest precipitable water values 
will peak at around 2 inches tomorrow afternoon and evening...and 
some localized street flooding issues could develop. The 
convection will linger into the overnight hours...with the trend 
of higher probability of precipitation translating east toward the Mississippi coast by 
daybreak on Wednesday. 


The parent trough will have lifted toward the northeast on 
Wednesday...but a lingering shortwave trough axis and some 
increased Omega will linger over the forecast area on Wednesday. 
Overall coverage will be lower on Wednesday...but some scattered 
to numerous showers and thunderstorms will once again be possible. 
Probability of precipitation will be highest in the afternoon hours when cape values peak 
around 2000 j/kg and precipitable water values remain high at 1.8 inches. Expect 
to see some stronger thunderstorms in the afternoon that could 
produce gusty winds...locally heavy downpours...and frequent 
lightning. Temperatures will be seasonably warm through the 
forecast period with highs in the middle to upper 80s and lows in 
the upper 60s and lower 70s. 


Long term... 


Heading into the latter half of the workweek and upcoming 
weekend...some weak shortwave ridging will develop over the area. 
Precipitable water values will fall from around 1.7 inches on Thursday to 1.5 
inches for the upcoming weekend. However...this will be a fairly 
dirty ridge...in that ample low level moisture will remain over 
the area and the middle- level cap will remain fairly weak. 
Thus...the risk of scattered diurnally forced convection will 
exist each day once the convective temperature in the middle 80s 
is achieved. With this in mind...have chance probability of precipitation of 30 to 50 
percent in the forecast each afternoon. Probability of precipitation drop to 10 to 20 
percent in the evening and overnight hours as daytime heating 
wanes and cape values fall from around 1000-1500 j/kg to under 500 
j/kg overnight. Temperatures will remain very summerlike with 
highs in the upper 80s and lows in the lower 70s. 


Aviation... 


Most terminals VFR...with a few sites reporting occasional ceilings 
around fl025. Scattered showers and thunderstorms across the area 
and carrying thunderstorms in the vicinity with short term amendments as appropriate. Most 
convection should dissipate near sunset...with VFR conditions for 
much of the overnight hours. Could see some MVFR ceilings around 
sunrise...with rain showers/thunderstorms and rain expected to begin percolating by middle- 
morning. Hi-res arw would indicate that we could actually have 
convection in the area around 09z Tuesday...although other solutions 
keep convection to the north of the area. Will monitor this for 00z 
taf package. 35 


Marine... 


A fairly strong and persistent onshore flow of 15 to 20 knots will 
linger through tomorrow in advance of an approaching upper level 
trough. These exercise caution winds will also keep seas elevated 
at between 3 and 5 feet in the open Gulf waters. More protected 
areas will see waves of 2 to 4 feet through tomorrow. As the 
trough lifts out on Wednesday...and the surface high gains 
strength over the Gulf...the onshore flow will fall back to around 
10 knots or less. Seas will also subside back to 3 feet or less. 
These conditions will persist through the upcoming weekend. 


Decision support...

Deployed...none. 
Activation...none.
