NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1036 am CDT Wednesday may 27 2015 


Update... 


Based on radar trends...meso-analysis...sounding discussion and 
observations the forecast has been updated for the squall 
line/mesoscale convective system that will continue moving through the forecast area late 
this morning and early this afternoon. Strong to marginally severe 
thunderstorms will be possible where some cell mergers occur...but 
the main concern the next few hours will be heavy rainfall over 
areas generally south of Baton Rouge to just west and southwest of 
New Orleans. The risk of more serious flash flooding and 
significant street flooding should be low if the outflow boundary 
continues to track southeast at a decent clip...however if the 
large clusters of storms persist too long...or if the outflow 
boundary slows down then the flash flood risk could increase. Will 
continue to monitor and consider a Flash Flood Watch before noon 
if the conditions warrant. 22/dew point 


&& 


Previous discussion... /issued 811 am CDT Wednesday may 27 2015/ 


.Sounding discussion... 


A very shallow saturated layer below the top of the temperature 
inversion allowed patchy fog to form in a few spots with reduced 
visibility noted at Bogalusa...McComb and Pascagoula. This 
temperature inversion is also the cap in place with inhibition 
calculated at about 150 j/kg. We continue to watch the line of 
thunderstorms over central Louisiana that is marching toward 
southeast Louisiana and southwest Mississippi. Plenty of cape 
around 1500 j/kg for this line to tap into...but 500mb winds are 
rather weak at just 15 knots. Radar show a downward trend in 
reflectivity values so if line continues to hold 
together...straight line winds would be the main concern. There is 
quite a bit of moisture up to 15000 feet above which there is 
significant drying. This drier air would be what could cause 
downburst winds with a downdraft cape at 1260 j/kg...which is 
above the 950 j/kg threshold. However...strongest gust of 38 knots 
was observed at 1201z at Lake Charles and 31 knots around 1300z at 
Jennings. 


As mentioned...quite a bit of moisture and precipitable water 
value of 1.66 inches is above normal for this time of year. Radar 
estimates from klch WSR-88D have shown widespread 1-2 inches with 
the initial line of thunderstorms and after the stratiform rain 
falls behind the main line...2-4 inches storm total. With weak 
upper level winds as discussed above...may have to watch rain 
rates for flash flooding. Recent mesoscale precipitation 
discussion issued by wpc also highlights this mentioning potential 
rain rates could exceed flash flood guidance. 


12z balloon info: no issues with the flight this morning that 
ascended to a height of 19.8 miles above the ground before 
bursting just northwest of Kiln 22 miles downrange from the 
office. The ascent lasted 107 minutes.

Previous discussion... /issued 308 am CDT Wednesday may 27 2015/ 


Discussion...quiet night over the County Warning Area but we continue to watch the 
activity working southeast out of northestern Texas and into western la. This should 
impact the region later today. This complex appears to be associated 
with a weak impulse and increased lift streaming in from the Pacific 
over the desert SW. 


Today should be far more active than yesterday. We have now 
recovered and abundant moisture is in place. Combine that with 
daytime heating today...the complex moving in from the northwest...weak 
troughing aloft...and the increase in lift working in and we 
should see scattered to num rain showers and thunderstorms and rain with convection beginning to 
develop possibly as early as late morning. Convection will 
continue to increase coverage as added influence from the 
Sea/Lake breeze kicks in. Greatest concentration of storms looks 
like it could be just south of the southwestern MS counties and north of a 
line from hum to nbg. As for strong to severe storms...there will be 
sufficient instability in place along with steep middle level lapse 
rates and this should get a few storms to overachieve. Lack of 
significant shear and middle level flow will keep organized severe weather 
from developing. Main concern from storms will strong to damaging 
straightline winds...frequent lightning...and torrential 
downpours. 


As has been mentioned convective coverage should be a little less on 
Thursday as short wave ridging moves in. Given that...afternoon heating and only weak 
subsidence aloft should not hold convection at Bay all day. Isolated 
to scattered storms will still be possible during the afternoon Thursday. As 
we head into Friday and the weekend things will become more 
summerlike as convection will be driven by diurnal influences. 
Afternoon convection will occur over land areas and then isolated activity 
will likely drift towards the marine zones. /Cab/ 


Aviation... tafs are still contingent on developments with squall 
line advancing out of NE Texas early this morning and interacting 
with Gulf Breeze convergence boundaries ahead of squall. Indicating 
tempo groups generally between 17z-21z that may need temporal 
adjustments based on radar trends later this morning. 
Otherwise...VFR conditions are expected outside periods of 
convection. 


Meffer/rr 


Marine... Bermuda high extends across the entire Gulf of Mexico and 
will remain in place through the rest of the week. This will keep 
southeast winds generally in the 8 to 14 knot range during this 
period with seas 1 to 3 feet. An approaching cold front middle weekend 
will break down the surface high and lead to weak pressure field 
over the area. Thus winds and seas will relax Sunday through early next 
week with winds under 10 kts and seas less than a foot.
