NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
840 am CDT sun may 24 2015 


Sounding discussion... 


Morning sounding indicating precipitable water at 1.40in with moist layers at the 
surface to 6kt and from 20 to 30kt. Wind profile shows deep southerly 
flow from the surface to 45kt. Convective temperature of 81 already 
exceeded at 8am so cumulus field developing rapidly. Not much in the 
way of any inhibiting factors in the sounding when it comes to 
lifting a parcel with a cape of 723j/kg and Li around minus 5. 
Surface to 1km shear calculation was 31kt with a brn shear at 11m2/s2. 
Plenty of support for thunderstorms today however widespread severe 
weather not expected. Plenty of support for very heavy rain 
associated with thunderstorms...frequent lightning and gusty 
outflow winds. Balloon burst at 111995ft above burgetown Road just 
west of Highway 11 in Carriere MS. /Keg/

Previous discussion... /issued 441 am CDT sun may 24 2015/ 


Synopsis... 


Surface map revealed a deep 1005mb low over northeast New Mexico. Southeast 
flow was present from Texas to Missouri and over middle and lower 
Mississippi Valley. Dewpoint readings of 70 degrees was from the 
Gulf Coast to the arklatex region. 00z precipitable water values 
showed moisture axis from Texas and Louisiana coast to eastern 
Oklahoma 1.75 to 2 inches. Upper air charts showed a cyclonic 
circulation just north of The Four Corners region and anti- 
cyclonic circulation over North Florida. Associated ridge axis 
extended north to the Great Lakes region. Southwest flow was 
present from Texas to middle Mississippi Valley with an embedded 
short wave over south Texas. 18 


Discussion... 


Short wave over south Texas will track northeast today bringing 
a squall line across west half of forecast area this afternoon. 
The main trough will move to the plains late tonight. Moisture 
axis of 1.75 inches will likely shift east from Arkansas/Louisiana 
and northwest Gulf. Middle layer instability is expected along with 
the moisture axis. Surface heating will create ll instability. 
Ergo...looking for convection to track across Louisiana and 
southern Mississippi this afternoon and tonight. Ergo...will carry 
elevated rain chances this afternoon and overnight. Moisture axis 
will remain in play Monday so will keep likely probability of precipitation for Monday. 
Another wave embedded in the southwest flow is expected to track 
across northwest Louisiana and bring a marginal threat of strong 
storms across the west half of forecast area on Tuesday. Trough 
will lift as another deepens over the West Coast and rockies 
Wednesday through Friday. Some model differences for next weekend 
as GFS show some relatively dry air tracking to the area from 
Florida and Euro shows another short wave approaching the next 
Sunday. Will show a slight increase in rain chances latter part of 
next weekend. 18 


Aviation... 


Most terminals are in VFR with a few observing MVFR due to either 
few/scattered lower cloud decks or light fog. Could see slightly more fog 
as sunrise approaches. Radar shows a few showers SW of khum at this 
time but the bulk of convection will begin developing late morning 
and into the afternoon hours. Models also indicate a line of 
moderate to heavy rain with thunderstorms will move in from the west 
late afternoon. IFR to LIFR conditions possible then with low visible 
from heavy rain. 


Meffer 


Marine... 


Surface ridge that was draped across the Appalachian 
Mountains and into the Gulf of Mexico is shifting east into the 
Atlantic. It will remain fairly close to the coast through midweek. 
Surface trough generally remaining west of the area over western 
Texas will keep the local pressure gradient fairly tight. The result 
of these surface features will be southeast winds in the 15 to 20 
knot range. So expect to see exercise caution headlines for much of 
the week. Upper level ridge will try to build in over the western 
half of the Gulf of Mexico late this week and into the weekend. This 
will weaken the gradient over the coastal waters and cause 
winds/seas to relax a bit.
