NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Jackson Kentucky 
840 PM EST sun Feb 7 2016 


Update... 
issued at 840 PM EST sun Feb 7 2016 


Eastern valleys have already reached the lower 30s and still 
likely have some to fall in the next 2 to 4 hours. With this in 
mind...have updated the forecast to include some freezing rain for 
the colder eastern valleys that are a bit more sheltered and won't 
likely recover in time before precipitation spreads in. Still 
looking like primarily rain as we keep a shallow layer of warm air 
just off the valley floors. Could still see some snow mix in on 
the ridges...but should be inconsequential as temperatures will 
remain above freezing and limit any accumulations. 


Update issued at 656 PM EST sun Feb 7 2016 


Valleys are dropping quickly this evening with the quicksand 
mesonet station already sitting in the lower 40s. Clearly guidance 
is not capturing this temperature fall this evening...so have 
lowered temperatures into the valleys through the rest of the 
evening...generally down to 30 to 32. We may need to go further 
yet...but this will be determined by how fast clouds can move in 
later this evening. Latest hi res models continuing to show most 
of what moves in late tonight being in the form of rain. The 
question remains how fast valleys come back up and thus if we can 
avoid a freezing rain in a few of our colder valleys. Higher 
terrain is still on track for snow...but initial dry air may cut 
into precipitation amounts late tonight. Thus...probably looking 
for under an inch in the higher terrain from anything that falls 
late tonight into tomorrow morning. Updates have been sent.

Short term...(this evening through Monday night) 
issued at 514 PM EST sun Feb 7 2016 


A highly amplified pattern is developing as a strong upper trough 
drops southeast over the eastern Continental U.S.. a very large low pressure 
system will move slowly southeast over the Great Lakes during the 
period. Its associated cold front will pass through the jkl 
forecast area Monday morning. Models agree on precipitation developing 
and moving into the area from the northwest late tonight...and 
temporarily exiting to the east on Monday morning. Low level temperatures 
are marginal for rain vs snow...and a mix is forecast for most 
areas. However...higher elevations near the Virginia border will be 
below freezing and see all snow. With accumulations expected to 
start there on Monday...have issued our winter weather advisories 
at this point. There is concern that decoupled valleys will fall 
below freezing and not recover before precipitation begins...and that 
warmer air just above the valleys will result in freezing rain at 
the surface. The probability of everything coming together for 
this is fairly low...and did not include it in the forecast at 
this time. 


Precipitation should move back in from west to east during the day 
Monday. Forecast sounding show significant cooling aloft as this 
round of precipitation develops...with steep lapse rates resulting in a 
deep layer. Convective currents may extend beyond the -20c 
level...and a few lightning strikes can not be ruled out. 


Temperatures will fall below freezing in all areas Monday 
evening. With snow showers continuing at times...the advisory 
expands to cover the whole forecast area at that point. 
Accumulations in any given period are not forecast to be all that 
great..but the prolonged nature of the event will eventually lead 
to advisory level snowfall. 


Long term...(tuesday through sunday) 
issued at 514 PM EST sun Feb 7 2016 


Models remain in good agreement...with deep and broad cyclonic flow 
setting up across much of the eastern Continental U.S. For a good portion of 
the week. This flow will aid in bringing cold air in from to northwest down 
into the Tennessee and Ohio valleys through the week. Now this broad cyclonic 
flow means that we are looking at a prolonged period of snow showers 
with embedded enhancements from time to time. This in lies biggest 
challenge that remains this afternoon for the period will be where 
and when do the pieces of energy move through the flow. These will 
provide additional enhancements to the snow showers through the 
start of the period. That said...the snow squall parameter would 
suggest some squalls are possible Tuesday afternoon...and this seems 
reasonable based on soundings with lapse rates above 6 c/km in both 
the low and middle levels. Therefore will keep likely probability of precipitation in the for a 
good portion of Tuesday. These snow squalls could lead to locally 
higher amounts of snow depending on where they occur and if they 
repeat over the same areas. Expect higher snow ratios and fluff 
factor for much of the period...given the cold air in place through 
the entire column and the at times convective nature of the snow. 


The deeper though axis is prognosticated to finally swing east as we move 
into Thursday...and will help cutoff the barrage of snow showers 
seen in the first part of the week. There is potential for another 
weak disturbance by Friday...however right now keeping most the 
precipitation across the southeast portions of the County Warning Area based on the model blend 
with fair amount of uncertainty. Models continue to struggle with 
phasing of the trough that moves east with a closed low upper low 
diving south out of central Canada. The GFS is much more progressive 
building a ridge into the middle of the central US...which hampers a 
deeper trough setting up further south in the NE US. These 
differences will have greatest implications of temperatures toward 
the end of the forecast period. Overall will lean toward the colder 
end since GFS has continued to trend colder over the past 4 runs 
based on the 850mb temperatures. 


&& 


Aviation...(for the 00z tafs through 00z Monday evening) 
issued at 656 PM EST sun Feb 7 2016 


VFR will last well into the night. After about 06z...rain and 
MVFR conditions and will begin to move in from the 
northwest...reaching the Virginia border by about 11z. Conditions will 
likely fall to IFR for a time as the precipitation moves through. 
A break in the precipitation is likely on Monday morning...but 
rain and snow showers should redevelop from west to east during 
the late morning and early afternoon. There could even be a few 
lightning strikes with the second round of precipitation.
