Severe Weather Alert Descriptions

 Freeze Watch  Statement as of 2:11 am CDT on October 31, 2014/


... Freeze watch remains in effect from late tonight through
Saturday morning...
... Freeze watch remains in effect from Saturday evening through
Sunday morning...

* temperatures... readings will fall to around the freezing mark
Saturday morning. Colder readings are expected Sunday morning
as The Heart of a much colder airmass moves across the Ohio
Valley. Expect temperatures to drop into the 20s for many
locations.

* Timing... breezy conditions Friday night will keep readings
from falling too fast. Freezing temperatures should begin a
few hours before daybreak and continue past sunrise. Calmer
conditions Saturday night will mean a quicker drop in
temperatures... with some locations reaching the freezing mark
late Saturday evening.

* Impacts... the freezing temperatures this weekend should bring
an effective end to the growing season. In addition...
scattered snow showers are forecast early Saturday morning
east of the I-65 corridor. A brief accumulation is possible in
areas where the snow rate is highest. Road temperatures will
be too warm for accumulations... however moderate snow will
reduce visibilities in some spots making driving hazardous.

Precautionary/preparedness actions...

A freeze watch means sub-freezing temperatures are possible.
These conditions could kill crops and other sensitive vegetation.






 Special Statement  Statement as of 3:11 am CDT on October 31, 2014/


... First snow of the winter season expected for much of the area
tonight and early Saturday morning.

Overview...

A very strong weather disturbance will drop southward out of
Canada and down through the Ohio Valley later today and tonight.
This feature will bring widespread rain showers and windy
conditions to the area. Northwest winds of 15 to 20 mph with gusts
of 30 to 35 mph will be possible this afternoon and tonight. Much
colder air will filter into the region tonight resulting in the
rain showers changing over to snow showers before diminishing late
tonight.

Snow potential...

As colder air pours into the region tonight... surface temperatures
are expected to drop from the upper 30s down into the lower 30s by
Saturday morning. Rain showers will change over to snow showers
during the evening hours. Some bands of moderate snow may develop
over portions of east-central Kentucky. While this snow will be
fighting relatively warm ground temperatures... a inch or less of
slushy snow on grass and elevated surfaces will be possible in
areas east of a line from Frankfort to Albany Kentucky. In areas out
toward I-65 and points west... little if any snow accumulation is
expected.

Cold temperatures...

Temperatures late tonight and early Saturday morning are expected
to drop to near freezing. However... even colder conditions are
expected Saturday night and Sunday morning as temperatures are
expected to drop into the mid to upper 20s. If temperatures drop
this low... this will result in a killing freeze and bring an end
to the growing season. At this time... freeze watches are in effect
for tonight and again on Saturday night.

Societal impacts...

With temperatures falling into the 30s tonight and winds gusting
into the 25 to 30 mph range... wind chill readings will make it
feel like it is in the lower 20s this evening. While light snow is
expected to fall tonight... surface temperatures are expected to
remain above freezing. This will result in area roadways remaining
simply wet. It is possible that a few icy spots may develop on
area bridges and overpasses toward sunrise on Saturday as
temperatures approach 32 degrees.

Stay tuned to NOAA all hazards weather radio and your local media
for the latest on this winter weather situation.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
915 am EDT Fri Oct 31 2014 


..forecast update... 
Issued at 910 am EDT Fri Oct 31 2014 


Tweaked pop grids to account for break in precip. Another round of 
light rain is coming in a few hours from the northwest, ahead of a 
cold front. That front will bring blustery conditions this 
afternoon, with gusts of 25 to 35 mph later this afternoon and 
evening. 


As for the snow chances tonight, we are still on track for some 
banded precipitation to occur as the upper disturbance now over Lake 
Michigan dives into central Kentucky. Latest WRF arw had a 
north-south oriented band of precipitation along the I-65 corridor 
from 01-09z which will bear watching to see if it plays out. Latest 
hrrr doesn't quite go out that far in time. 


Short term (now through saturday)... 
issued at 300 am EDT Fri Oct 31 2014 


..windy conditions and falling temperatures expected today... 


..Wintry mix likely this evening changing to snow with minor 
accumulations possible east of I-65... 


=================================== 
short term synopsis 
=================================== 


In the near term, first in a series of upper level waves is 
transversing the region. This will bring mostly cloudy skies to the 
region early this morning with scattered showers moving through the 
area. Associated with this lead wave is a surface cold front off to 
the northwest. This feature will swing through the region and allow 
much colder air to filter into the region from the northwest this morning 
and through the afternoon hours. 


Secondary/potent and unseasonably strong upper trough will drop 
nearly southward out of the Great Lakes and into the eastern Ohio 
Valley tonight. This feature, combined with strong cold air 
advection aloft will result in quite a bit of lift in the atmosphere 
to produce widespread shower activity. As the colder air aloft 
descends further toward the surface this evening, the rain showers 
will change to a wintry mix before ending a snow showers late 
tonight and Saturday morning. Some of the snow showers this evening 
may occur in bands and may be locally heavy...resulting in minor 
snow accumulations in areas mainly east of I-65. The strong upper 
trough will pull off to the south and east during the day on 
Saturday resulting in drier conditions moving in from the W/NW...but 
unseasonably cold temperatures are expected. 


=================================== 
Model preference & confidence 
=================================== 


Tonight's model guidance continues to show relatively good 
continuity from previous runs and are generally in good agreement. 
The multi-model consensus suggests higher probabilities of 
precipitation today with the two systems moving through the region. 
Thus, will be increasing pops for this afternoon and evening. All 
model data suggest the pressure gradient will increase and 
northwesterly winds of 15-20 miles per hour with gusts up to 30-35 miles per hour will be 
possible late this afternoon and evening. The higher resolution 
models continue to show the strong potential for trowal formation on 
the backside of the upper wave coming through the region tonight. 
These trawl's's can set up banded heavy precipitation and with 
thermal profiles crashing tonight from top to bottom, current 
thinking is that some bands of moderate to heavy snow will be 
possible across our eastern areas. Snow accumulations will continue 
to be a challenge as the snow will be fighting relatively warm 
ground temperatures and there is some uncertainty where any banded 
precipitation develops. 


Have generally favored the short term multi-model consensus for this 
forecast. Have generally used a blend of the superblend model 
guidance for hourly T/TD which is fairly close to the raw 2m temps 
from the NAM/GFS...but slightly cooler than the statistical MOS. We 
expect precipitation to gradually diminish late tonight as upper 
level forcing exits the region and a decent push of drier air works 
in aloft from the NW/W. This drier air will infiltrate the entire 
region during the day on Saturday. 


Forecaster confidence on precipitation chances are higher than 
average for today and tonight given the relative low spread in the 
deterministic and ensemble guidance. Forecast confidence on 
temperatures is also higher than average for today and tonight. 
Medium confidence on temperatures for Saturday exists due to 
lingering uncertainty in how much clearing will develop from west 
to east during the afternoon hours. 


=================================== 
Sensible weather impacts 
=================================== 


For today, cloudy conditions with passing rain showers will be the 
rule across the region. Daytime high temperatures will occur this 
morning prior to the cold front pushing through the region. Highs 
will range from the upper 40s in the northwest to the lower 50s in 
the southeast. Once the front clears the area this afternoon, 
northwesterly winds will pick up and sustained winds of 15-20 miles per hour 
with gusts of 30-35 miles per hour will be possible this afternoon and evening. 


Temperatures are expected to fall throughout the afternoon and 
evening and will likely cool into the upper 30s to around 40 by 
early evening. As the evening wears on, colder air aloft will work 
its way downward and allow precipitation to mix with snow. It 
appears that all precipitation will likely end as snow showers as 
thermal profiles cool sufficiently. At this time, rain will be the 
pre-dominant precipitation type through early evening with a 
rain/snow mix beginning around 7-8 PM and then a complete change 
over to snow occurring by 11pm to midnight. Surface temperatures 
this evening will likely remain above freezing. Thus any mixed 
precipitation will not accumulate on roadways and hazardous Road 
conditions are not expected. The combination of falling 
temperatures and gusty winds will lead to wind chill readings 
falling into the upper teens to the lower 20s. 


Late tonight, temperatures will approach the freezing mark...most 
likely after 3 am or so. Light snow will likely be ongoing in areas 
east of I-65 and if banded precipitation sets up, the snow may be 
moderate to occasionally heavy at times. The snow will be fighting 
off relatively warm ground temperatures, so accumulations will be 
difficult unless moderate/heavy precipitation occurs. With this 
thinking in mind, we feel some minor accumulations will be possible 
in the eastern third of our forecast area...east of I-65. The 
highest chances of accumulation looks to be generally in areas east 
of US 27/127. Accumulations of a dusting to a light slushy 
accumulation mainly on grassy and elevated surfaces will be possible 
in this area. 


Out west of I-65, some clearing will take place as this area will be 
further west and in the more drier air. If clearing takes place, 
temperatures will have the potential to drop to around 30 degrees. 
The pressure gradient will likely remain elevated enough to preclude 
frost formation. With temperatures expected to be close to 
freezing, will leave the current freeze watch in place to preserve 
continuity. However, it appears that Saturday night will be much 
more favorable for a season ending, killing freeze. 


For Saturday, the upper trough will pull away from the region. 
However, low clouds and some light precipitation may still be 
ongoing out across our far eastern sections. Slow clearing will 
work across the central parts of the region. It will be a 
cool/crisp day with high temperatures only warming to around 40 in 
areas east of US 27/127 with lower to middle 40s possible out in the 
I-65 corridor and points west. 


Long term (saturday night through thursday)... 
issued at 244 am EDT Fri Oct 31 2014 


..sub-freezing temperatures expected Sunday morning... 


Cold high pressure will move directly over the region Saturday night 
into Sunday morning. Any lingering clouds Saturday evening across 
the Bluegrass should clear out overnight. This will lead to a decent 
setup for radiational cooling with the lowest temperatures of the 
season expected. Lows on Sunday morning are expected to drop into 
the mid to upper 20s in most locations, though the Louisville Metro 
may stay right around 30. These temperatures should put an end to 
the growing season. 


High pressure will shift east through the beginning of next week and 
heights will build aloft. Temperatures will gradually warm through 
Tuesday. While highs on Sunday will reach only into the upper 40s to 
lower 50s, highs on Tuesday will be back into the mid 60s. Morning 
lows will correspondingly increase to the lower 50s by Wednesday 
morning. 


The next system will affect the area midweek as a low pressure 
system across Canada swings a cold front through. A few showers may 
be possible Tuesday afternoon ahead of this front. However, the bulk 
of the precipitation should move through Tuesday night and Wednesday 
with showers likely across much of the area. Showers will move out 
Wednesday night with just a few lingering in the east Thursday 
morning. This front will bring cooler temperatures for the end of 
next week, though they are not expected to be nearly as cold as 
temperatures this weekend.

Aviation (12z taf update)... 
updated at 642 am EDT Fri Oct 31 2014 


First in a series of mid-level disturbances is moving through the 
region this morning. This has brought widespread clouds and light 
precipitation. Expect ceilings to hover around the MVFR/VFR 
threshold this morning with precipitation moving east of kbwg/ksdf 
by 31/14z and then exiting the klex terminal by 31/15z time frame or 
so. As we see a brief lull in the precipitation, winds will shift 
to the northwest and start to pick up. 


For this afternoon/eve, widespread shower activity should pick up 
once again as a stronger and more potent upper level wave dives out 
of Wisconsin and toward eastern Kentucky. This will bring an increase in 
winds from the northwest with sustained speeds of 12-16kts and gusts up to 
25-30kts. Rain showers and MVFR ceilings are expected at the 
terminals. Colder air will push into the region this evening 
resulting in the rain showers changing over to snow showers. Snow 
will likely bring the most impact over at klex where MVFR cigs/vsbys 
will be possible after 01/03z.
