NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
1134 am CST Thursday Dec 18 2014 


Update... 
quick update mainly to increase probability of precipitation and adjust weather for the 
today and tonight periods to account for higher rain chances based 
on recent radar trends and latest model guidance. Otherwise...no 
additional updates are anticipated before the afternoon package. 


&& 


Previous discussion... /issued 654 am CST Thursday Dec 18 2014/ 


.Sounding discussion... 


The precipitable water value is increasing as moisture is being 
drawn into our area this morning. Winds throughout the atmosphere 
are from the west or west-southwest except in the lowest 2000 
feet. At 37500 feet the maximum wind speed of 116 knots was found. 
This morning/S surface inversion is around 3300 feet thick. Two 
smaller inversions exist around 10000 and 25000 feet. Temperatures 
are generally lower from 5000 feet up and higher below 5000 feet 
compared to 24 hours ago. 


12z balloon info: the balloon reached a height of 20.3 miles above 
the ground bursting 88 miles downrange north of Grand Bay MS. 
Flight time this morning was 97 minutes.

Previous discussion... /issued 356 am CST Thursday Dec 18 2014/ 


Short term... 
high pressure will give way to a more unsettled pattern. Each 
model sounding showing moisture recovery as precipitable water values rise in 
response to a more easterly flow regime. Round one will be in 
the form of a short-wave later today and tonight with a chance 
of rain higher as you go northwest in our forecast area. The 
main trough will be round two as it digs over the Central Plains. 
Surface based cyclogenisis evident as all the models agree on 
the formation of a low pressure center between kbro and kcrp over 
the King ranch. The low is prognosticated to move NE across the northern 
Gulf of Mexico to the Louisiana coast and across southeast la/S MS on 
Friday. Each model run is a tad further south which alters the 
impact to our forecast each run. The low will bring showers and 
thunderstorms to the area Friday and Friday night. A warm front 
will move from the Gulf northward across the area Friday morning in 
response to the approaching low pressure. Wind forecasts indicate a 
50kt jet in the low levels quickly pushing moisture northward. 
Some showers will linger into Saturday morning ending from the 
west by noon. Examining the impacts to the area... the further 
the low tracks south the lower the chance for severe weather for 
sela...sms...and the MS Gulf Coast. GFS quantitative precipitation forecast forecasts over 2 inches 
in an elongated blob from klft to kmob north of the low. So severe 
or not...some areas will get much needed rain...thus forecast 
fairly high probability of precipitation from this system. Looking at some science for 
severe chances...highest cape prognosticated to pass along the coastal 
waters peaking around 800 j/kg. Noticed the best Omega lift well 
north of the front all north of Lake Pontchartrain where the best 
probability of precipitation and precipitation efficiency will take place. Not impressive 
lapse rates to support hail threat...however there is some decent 
shear. Shear values prognosticated to be from 400 to 580 m2/s2 in the 0 to 
3 km range peaking at 00z Sat. Deducing the severe chance taking 
into account the current forecast for the low track points to a 
typical low instability...high shear... elevated convective 
threat. The best threat for severe weather would be along the 
coast to offshore however... there would remain a threat for heavy 
rain...straight line winds... and with the high shear values...an 
isolated tornado or two on Friday and Friday night before the 
system moves east. Keg 


Long term... 
round three comes Tuesday with a significant pattern change over 
the eastern Continental U.S.. a large econus trough develops Monday with 
cyclogenisis over Montana Rushmore per the GFS and over the Hawkeye 
state per the European model (ecmwf). The low carves and becomes quasi stationary 
over the Great Lakes. The dragging baroclinic zone will impact our 
area with a chance for rain Tuesday ending in the evening. Looks like 
there will be some support from a 150kt 300 mb jet and some 
instability. Looking at 18z Tuesday convective data shows the main 
instability remains offshore once again but some stronger lift 
will take place along the ensuing baroclinic zone. S MS cape 
values prognosticated at 200 j/kg with 1200 j/kg in our offshore waters. 
The best lift is prognosticated in central MS. So...another chance for rain 
and possibly some thunderstorms. Severe looks marginal once 
again.... however confidence on this system is low concerning the 
areal impacts. One thing for certain is a sharp drop in 
temperatures following the front with a high pressure center over 
khum peaking at 1019 mb. Looks to be a very pleasant December 25th 
with clear skies...highs around 60 and lows in the middle 30s to low 
40s. We will keep a very close eye on what looks to be a strong 
pressure gradient with the cold air advection or cold air advection Wednesday. 
Swan/wwa and synoptic models indicated a significant rise in seas 
with the increase in winds. Possible gales in the coastal and 
offshore waters and with around 30mph over land. Keg 


Aviation... 
warm frontogenesis process next 12-18 hours along the Gulf Coast 
will bring a slow lowering of ceilings from southwest to northeast. 
VFR conditions through at least 20z before lowering to MVFR 
bkn020-025 at kbtr and kmcb before 19/00z...then spreading eastward 
to other terminal locations by end of taf valid period. Some IFR 
ceilings around broken-ovc007 may develop at kbtr by 19/12z. Will handle 
convective development with prob30 group at this time for kmcb and 
kbtr for after 19/06z with -shra though isolated thunderstorms and rain can not be 
ruled out by end of taf period. This may be better handled with 
tempo group in subsequent taf package issuance. 24/rr 


Marine... 
as a low pressure system forms along the Texas coast and moves 
over the coastal waters Friday...winds will become more southeast 
and increase to 15 to 20 knots with seas 3 to 6 feet. We will 
likely raise the small craft exercise caution with this low. There 
could be some thunderstorms Friday and Friday night... some strong 
ones as the low passes. High pressure will build over the weekend 
before the next system impacts the marine area. Another low and a 
front will increase the winds and seas again Monday night into 
Tuesday. This system will produce a strong pressure gradient and 
could warrant a Small Craft Advisory. There is an indication in 
the offshore waters especially in the eastern marine zones gales 
could be reached. Seas will be 6 to 10 feet late Tuesday and 
especially Wednesday creating a very hazardous environment for 
mariners. Keg
