NWS Forecaster Discussion




Area forecast discussion 
National Weather Service New Orleans la 
404 am CST Friday Dec 19 2014 


Synopsis... 
three systems to watch as an active pattern is underway through 
the middle of next week. Round one is a short wave and low 
pressure center or open wave moving from Texas to the la coast today 
and tonight. Round two will be a chance of rain associated with a 
warm frontal boundary moving north from the Gulf associated with 
the next much more synoptically vigorous round 3 system which will 
sweep a cold front into the coastal waters on Tuesday. Keg 




Short term... 
round one rain is knocking at our door this morning as a short 
wave approaches with an associated low pressure developing on a 
warm front. Precipitable water up to 1.38 on 00z sounding. Satellite estimates precipitable water 
values up to 1.6 inches now. Did an old fashioned hand analysis 
this morning with paper and a real pencil... cyclogenisis underway 
with a low currently over kcrp. Rain associated with this system 
in Texas and SW la overnight with a few lightning strikes showing 
up this morning. Some small hail reports in Texas where lapse 
rates were more supportive. Main impact from this first system 
will be rain as the current track of the low stays along the coast 
keeping the most unstable air well in the Gulf. 600-800 j/kg cape 
in the Gulf at 18z with any significant shear out pacing the rain 
today. With weak instability severe chances should be low. Expect 
to see some elevated thunderstorms today and with added 
iscentropic lift some areas of heavy rain can be expected. HPC 
analysis looks good with a 1 to 3 inch quantitative precipitation forecast swath well north of the 
low where rain will be most efficient. Impact should be low as the 
rivers are low and the soil is dry. There is a marginal risk of 
severe weather today with some threat of a high winds and elevated 
mesos. The system should move out by noon Saturday. Keg 


Long term... 
round two is on Sunday as a deepening short wave in the middle west 
forces a warm frontal boundary north. Some showers will develop 
on the front mainly impacting the coast...southeast la and MS Gulf Coast. 
Looks like most of the instability will be offshore again with 
this system limiting chances for severe weather. 


A pattern change for the econus comes next creating our round 3 
event which will clear out the moisture. A deepening low bottoms 
out around Cresco Iowa at 06z Tuesday per the GFS. The trough digs 
south as the low moves north and centers over New Richmond 
Wisconsin by 18z Tuesday and strengthens a baroclinic zone. A cold 
front will push through Tuesday and bring another chance for rain. The 
European model (ecmwf) is more aggressive with the rain chances than the GFS but 
both agree the higher amounts are offshore. 600 j/kg cape ahead 
of the front with very little shear. There is weak instability 
forced along the front but it does not appear to support 
widespread severe weather. Cooler temperatures to follow as a 
high pressure centers over deep south Texas. The high moves 
quickly east bringing southerly flow back to our forecast area. 
For the 24th and 25th skies will be mostly clear...nights cool... 
and temperatures in the upper 60s. Could see lower 70s in some 
areas by the 26th. Keg 


&& 


Aviation... 
much of the next 24 hours will be dominated by low end MVFR to IFR ceilings 
and...at times...IFR visibility in heavy rain showers/isolated thunderstorms and rain with Gulf low 
transiting the coast through tonight. Conditions will be lower at western 
terminals initially then spreading eastward through the late morning hours. 
Not anticipating any appreciable improvements until shortly after this 
taf valid period...generally after 20/15z. 24/rr 


&& 


Marine... 
a short wave and low pressure along a warm front will move through 
the coastal waters today. Each model run has moved the track of 
the low further south and if weak enough will just be an open 
wave. Showers and thunderstorms are likely as the low tracks 
east...some of the storms could be strong with gale force gusts 
and locally rough seas. The low will move out Saturday keeping an 
old frontal boundary in the offshore waters. A trough of low 
pressure digs south forcing the warm front north on Sunday. This 
will bring another chance for rain and a few thunderstorms Sunday 
through Tuesday. A stronger system will bring a cold front into 
the coastal waters Tuesday clearing out the area. However... this 
front is strong enough to produce some strong winds associated 
with the cold air advection across a frictionless water surface. 
The winds and rough seas will likely warrant a Small Craft 
Advisory Tuesday and Wednesday. Mariners should plan accordingly for the 
middle of next week. Keg
