Area forecast discussion 
National Weather Service Louisville Kentucky 
1205 am EST Fri Dec 19 2014 


..updated aviation discussion... 


Short term (now through Friday night)... 
issued at 300 PM EST Thu Dec 18 2014 


The synoptic pattern this afternoon features zonal to west-southwest 
upper-level flow across the Ohio Valley, through which a dampening 
shortwave was traveling. This shortwave will push through the 
region this evening, but another weak southern stream disturbance 
will push in towards the end of the period and into the long term 
period. 


As expected, the very dry airmass between 900 and 750mb has largely 
won out this afternoon over the region, as isentropic ascent above 
this layer has not been enough to overcome it. A few locations have 
seen a few flurries/ice pellets/sprinkles, but most have remained 
dry and should remain dry through the rest of the evening. 


The cloud and resultant temperature forecast will be very tricky 
tonight, as it does appear a few breaks in the clouds may occur 
towards Friday morning. The latest rap/hrrr depict similar 
solutions in breaking up the cloud cover tonight across portions of 
central Kentucky and southern in. Forecast soundings from the synoptic 
models also support this potential as drier air works in in the 
800-600mb layer. Am always hesitant to forecast skies clearing this 
time of year, but given the model agreement, will reduce sky cover 
amounts overnight. Still think we will see at least some cloud 
cover almost all night, but large breaks coupled with generally calm 
winds may allow temperatures to drop into the low to mid 20s, 
perhaps even lower if the clouds break sooner. If they don't break 
at all, then obviously these temperatures will be way too cool. 
Certainly a tricky forecast and one the evening shift will monitor. 


Friday will be dry as high pressure remains in control. 
Temperatures will once again be dependent on the amount of cloud 
cover we see (likely more clouds in the afternoon/evening than in 
the morning). Will go with highs in the upper 30s and lower 
40s. 


Attention will then turn to the southwest as the next system 
approaches the Ohio and Tennessee valleys. Guidance continues to suppress 
this system further south, with the GFS/European model (ecmwf) on the northern end of 
the envelope, while the hi-res parallel GFS/NAM/wrfs all point to a 
more southern solution. Looking at the forcing progs, really don't 
see anything to support widespread precip in our area. The coupled 
jet structure seen a day or two ago is largely gone as guidance has 
now backed off the idea of a stronger northern stream jet streak. 
All the low-level ascent associated with frontogenesis and low-level 
moisture transport are focused well to the south of the region. 
Therefore, all we really have to work with will be weak upper-level 
ascent brought on by the left-exit of the southern stream jet streak 
and very modest mid-level height falls as the dampening wave pushes 
through. With all this in mind, have continued to trim pops with 
this package. Kept 20-30 pops in the far southeastern County Warning Area mainly 
just to keep some forecast continuity, but suspect the drier hi-res 
models will end up being right with little to no measurable precip 
in our area. 




Long term (saturday through thursday)... 
issued at 300 PM EST Thu Dec 18 2014 


High pressure will be over the upper Ohio Valley at the start of the 
period. This high will ridge across our area through the weekend. 
Will keep in some lower chance pops for light precip during the day 
Saturday as a system passes by well south of the region. The next 
precip chance is Sunday night as a weak vortmax crosses the Midwest. 
This system is the first in a series of disturbances crossing our 
area the next work week as a large upper low deepens across the 
Great Lakes and south central Canada. These systems will bring 
multiple precip chances to Christmas day. One such system looks 
to drag a surface low across the region Tuesday and then another by 
the end of the work week. The exact placement of these systems will 
determine the type of precipitation we get. For now, have a band of 
rain/snow chances along the Ohio River Sunday night, with little if 
any accumulations. The GFS has the Tuesday low going up the Ohio 
River, which brings a typical line of showers through with winter 
precip fighting drier air filtering in on the back side. 


Much colder thicknesses come in for midweek, with an impressive 
fetch of moisture from the Great Lakes potentially bringing some 
rain or snow showers Christmas eve. Then we warm up slightly on 
Thursday as the next low develops across the Southern Plains and 
lifts a warm front back across the region.

Aviation (06z taf update)... 
issued at 1200 am EST Fri Dec 19 2014 


Ceilings through the mid-morning hours will stay VFR with bases 
above 4k feet. Some breaks in the clouds will approach sdf and Lex 
after 06z, with ceilings occasionally scattering out. Ceilings will 
become scattered towards dawn, with variable cloudiness expected 
during the day Friday, with any ceilings staying VFR. 


Winds will stay very light during the entire taf period with 
north winds averaging around 5kt.
