NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
1223 am EST Thu Dec 18 2014 


..updated aviation discussion... 


Short term (now through Thursday night)... 
issued at 250 PM EST Wed Dec 17 2014 


..light wintry precip late tonight and Thursday morning... 


A shortwave trough now over southeast nm will advance toward MO by 
daybreak Thursday. Current precipitation over OK and northwest Arkansas 
will move toward US as well, bringing light precip to the southwest 
half of the forecast area after midnight. This precip will have to 
overcome some dry air initially at low/mid levels of the atmosphere, 
but expect this to happen in the 08-13z window. Temperatures will be 
cold enough for a wintry mix of precipitation, as clearing skies 
this afternoon should, despite upper clouds thickening this evening, 
allow for several hours of good radiational cooling conditions 
through the evening hours. Thus by midnight, many areas getting this 
precip should get down to around 30 degrees. 


The cold layer aloft may be deep enough to allow for either snow or 
sleet, but a few model soundings show enough warm air aloft that 
freezing rain cannot be thrown out of the mix yet. In addition, 
winds will be light enough and the coldest air remaining over our 
southeast counties may be moist enough for some patchy freezing fog 
to occur ahead of any precip. Lots to watch for in other words. The 
saving Grace here is the dry air aloft evaporating a lot of the 
precip as well as the short duration of the event, keeping quantitative precipitation forecast 
light. Have an area of half inch accumulations for snow along an 
axis from Hartford, Kentucky to roughly Glasgow. Also have a few 
hundredths of ice accumulations. These light values warrant issuing 
a Special Weather Statement highlighting these threats. 


The rest of the day Thursday should remain cloudy and cold, with 
highs stuck in the 30s. Diurnal curves will be narrow for 
temperatures as cloud cover sticks around Thursday night as well, 
leaving lows in the mid to upper 20s. 




Long term (friday through wednesday)... 
issued at 302 PM EST Wed Dec 17 2014 


The synoptic pattern at the start of the long term period will 
feature a ridge across the western conus, with a downstream trough 
across the south-Central Plains. This trough will deamplify as it 
pushes into the Ohio Valley this weekend. A more substantial, 
anomalous trough will then build into the Ohio Valley towards the 
end of the period (around Christmas eve). 


The main focus of the long term period continues to be on the 
upcoming weekend system, slated to move through the region Friday 
night into Saturday. The latest model guidance has continued to 
trend weaker and further south with this system. The 17/12z 
operational NAM is the most aggressive with quantitative precipitation forecast into the Ohio 
Valley, owing to the fact it is a bit more negatively tilted and 
stronger with the mid-level shortwave and associated surface low. 
However, the European model (ecmwf)/GFS/Gem solutions, along with the 17/15z sref 
solutions, depict more of an open, positively-tilted shortwave which 
keeps the system more suppressed and weaker. Looking at the 
forcing, it appears the better moisture transport and 
frontogenetical circulations will be well south of the Kentucky border. A 
coupled jet structure, with a rapidly weakening northern stream 
branch, will be the main driver of precipitation this far north, 
which means amounts/rates should remain light. Given the agreement 
of these solutions and rather meager forcing progs, have trended the 
forecast drier and further south. 


What this means for the sensible weather in the Ohio Valley is less 
in the way of impact, and more of just a glancing blow of perhaps 
some light wintry precip. Model soundings still differ a bit on 
their solutions, with some even suggesting some light sleet 
mixing in as this system passes, but will leave that out of the 
forecast for now. Some minor snow accumulations, mainly on grassy 
surfaces, still appear possible generally along and southeast of a 
line from Leitchfield to Richmond. Further northwest, some light 
snow may fall, but do not expect much in the way of accumulations 
given the light quantitative precipitation forecast and poor rates to overcome warm grounds/roads. 


Once this system passes, high pressure will build into the region 
Sunday into Monday. However, by Monday night, an anomalous trough 
will be diving into portions of the central conus, with a surface 
low expected to rapidly deepen somewhere over the eastern United 
States. Ensembles and long range deterministic guidance have been 
hinting at this system for days, so confidence is high in a 
significant storm somewhere over the eastern Continental U.S.. however, 
details continue to remain murky on whether this system will impact 
the Ohio Valley in the form of rain, snow, or a wintry mix. For 
now, taking an ensemble approach, it appears this system will be 
mostly rain on the front side Monday night into Tuesday, changing to 
snow as cold air quickly filters in Tuesday night into Wednesday. 
Given the impact on the Christmas Holiday, this is certainly a 
system we will continue to monitor closely.

Aviation (00z taf update)... 
issued at 1215 am EST Thu Dec 18 2014 


Wintry precipitation associated with a weakening Southern Plains 
storm system will almost completely dissipate prior to reaching sdf 
and Lex. For these two sites, expect only some flurries or light 
sprinkles after 14z this morning at worst. 


Light snow or light mixed precipitation is possible at bwg beginning 
around 10z and continuing through 15z. MVFR visibilities and 
ceilings will develop if any of this occurs. After light 
precipitation ends, expect MVFR ceilings later this afternoon. 


Over the next couple of hours, sdf and Lex will lie near the 
southern edge of an extensive MVFR shield of strato-cu. Based on 
satellite imagery, think that sdf will trend towards VFR ceilings by 
around 07z, with Lex ceilings rising to VFR by 08z. 


Winds will stay generally from the north overnight and Thursday at 
around 4 to 8kt.
