NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
825 PM CDT Sat Apr 18 2015 


..sounding discussion... 


A very moist atmosphere was sampled from the surface to the 
tropopause this evening with a precipitable water /pw/ value 
calculated at 1.92 inches. This precipitable water is a new record for this 
date/time as the old record precipitable water was 1.84 inches according to the 
Storm Prediction Center sounding climatology. While there is some instability with 
SBCAPE of 1250 j/kg and Li of -4 and bulk shear of 55 knots and 
0-3km srh around 200 m2/s2...this environment was not able to be 
realized with limited daytime heating and severe threat is waning 
this evening. Heavy rain may be a threat if storms can line up and 
train over the same area...but with no boundary in the area this 
seems low. In addition...0-6km mean wind is 26 knots so storms 
will be moving and not remaining over one location very long. 


00z balloon info: the flight lasted 94 minutes 
this evening terminating at a height of 18.8 miles above the 
ground near Wiggins 56 miles downrange from the office.

Previous discussion... /issued 346 PM CDT Sat Apr 18 2015/ 


Synopsis... 


Since the departure of the morning rain area...there has been 
little in the way of precipitation development across the 
area...as clouds never really got out of the way to allow 
significant destabilization. In addition...convective complexes 
over the Gulf of Mexico have limited moisture transport into the 
area. Temperatures have generally remained in the middle and upper 
70s...although a couple of spots may nose above 80 degrees before 
the end of the day. 


Short term... 


Plenty of wild cards in the forecast over the next 36 hours or so. 
Upper low over eastern Colorado is expected to open up and get 
absorbed by upper trough traversing the U.S-Canadian border. 
Impulses focusing the Gulf convection will move across the area 
overnight with another batch of showers and scattered 
thunderstorms expected. Threat of widespread very heavy rain is 
diminishing somewhat...especially with the Gulf convection 
continuing. In addition...rain amounts over the last 72 hours has 
only been around 1 inch in most areas...and flash flood guidance 
has rebounded across the area. Will get rid of Flash Flood Watch 
with package issuance. If Gulf convection were to dissipate this 
evening...there would be a brief window of heavy rain potential 
before drier air reaches the area. 


Second concern will be the threat of severe weather on Sunday. 
Moisture will be diminishing through the column on Sunday...but 
lapse rates will be steepening. NAM soundings significantly more 
unstable than GFS soundings...but both support severe weather. If 
thunderstorms develop...and that is uncertain this far 
south...there will be potential for damaging winds and hail. Will 
only be carrying probability of precipitation in the 20-30 percent range Sunday and Sunday 
night...which is higher than guidance in quite a few places. 


Significantly drier air will arrive on Monday with cooler 
temperatures for Monday and Tuesday. Even then...temperatures will 
only be near normal for middle to late April. 35 


Long term... 


Middle level flow becomes more zonal across the area at middle week. As 
surface high pressure moves to the Atlantic coast...onshore flow 
will return moisture and present a potential for a few showers or 
thunderstorms by Wednesday or Thursday. Start to see some 
differences in medium range solutions beyond that and will blend 
solutions for now. Will not be a completely dry period...but not 
as wet as the past week here. 35 


Aviation... 


VFR and areas of MVFR conditions due to ceilings will prevail 
through the remainder of the afternoon and into the evening hours 
at each of the terminals. The main area of rain from earlier today 
has moved off to the east of the taf sites...however some new 
development was occurring. Khum...kbtr and kmcb are the sites most 
likely to see more shower and thunderstorm activity this afternoon 
from this new development. Ceilings will lower into the IFR 
category overnight...after 06z...with areas of fog also possible. 
Improving conditions will be observed after 15z Sunday with MVFR 
ceilings again dominating. 11 


Marine... 


Light to moderate south and then southwest flow will prevail tonight 
into Sunday before becoming northwest Monday in the wake of a cold 
front. Moderate offshore flow will then will be observed Monday 
night into Tuesday in the wake of this boundary. High pressure will 
shift east across the central Gulf Coast region through the middle week 
period with generally light easterly flow becoming southeast and 
then south. 11 


Decision support... 


Dss code...yellow. 
Deployed...none. 
Activation...none. 
Activities...monitoring severe weather threat through Sunday.
