NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
137 PM EDT Wed Aug 20 2014 


..updated forecast and aviation discussions... 


..Forecast update... 
issued at 135 PM EDT Wed Aug 20 2014 


Complex across central Illinois is holding together fairly well 
early this afternoon. Have a pretty thick canopy of cirrus out ahead 
of the storms, but it may hold together enough as it moves into our 
forecast area. High-res models are not too gung Ho about rain 
chances in this area this afternoon, but with a very unstable 
surface-based atmosphere in our region, Storm Prediction Center mesoanalysis has 4-6 k 
CAPES, just cannot rule out storms developing/maintaining. Have 
shifted the highest pop axis a little south, to a Huntingburg, in to 
Danville, Kentucky line. Will continue to watch incoming pattern for 
updates through the afternoon. 


Issued at 1135 am EDT Wed Aug 20 2014 


Partly cloudy skies were noted across southern Indiana and central 
Kentucky this morning. Temperatures ranged from the upper 70s to 
near 80- in the east/northeast with lower 80s generally in the I-65 
corridor and points west. From the Kentucky mesonet data and visible 
satellite imagery, there appears to be boundary draped across the 
southern part of the forecast area. This evident in the dewpoint 
readings across southern Kentucky which are in the middle 70s with only 
upper 60s to lower 70s across our NE sections. 


A decaying mesoscale convective system over central Illinois will continue to spread mid-high 
level cloudiness down into mainly western Kentucky this afternoon. These 
clouds along with the boundary in the region may serve as a focus 
for convective development later this afternoon. The high 
resolution convection allowing models have vastly different 
solutions. The latest runs of the hrrr keep much of our region dry 
thought the day with convection mainly developing out to our west. 
While the NSSL WRF arw runs develop convection up near cvg and drop 
it southeast into weather forecast office jkl's region. The mixed signals in the guidance make 
this forecast particularly challenging this afternoon. 


For now, have kept the current forecast on track. Current thinking 
is that convection will probably start to develop over the next few 
hours along the left over boundary...given multiple convectively 
induced lifting mechanisms cross the region. Damaging winds and 
perhaps some large hail will be possible with the storms this 
afternoon as moderate instability combined with around 30 kts of 
west-northwest flow aloft will be in place across the region. 


Short term (now through thursday)... 
issued at 340 am EDT Wed Aug 20 2014 


A complex short term forecast is in store with multiple rounds of 
strong to potentially severe convection possible as potent 
shortwaves topple a central Continental U.S. Ridge and dive southeast into the 
Ohio Valley. In addition, the eastern edge of a warm front will 
slowly lift north over the region over the next few days providing 
focus for convection. Also left over boundaries from storms 
will provide focus for renewed convection over the next few days 
with convective activity peaking during the afternoon and evening 
hours during best instability. 


As of 315am this morning, convection over the Bluegrass region was 
causing mainly very heavy rainfall and lots of lightning. A Flood 
Advisory is effect for northern Harrison County Kentucky through 6am this 
morning due to training storms over that area. The Harrison County 
mesonet has received 1.34 inches of rain so far with impressive 
rainfall rates which may cause minor flooding issues. 


Think that this complex of storms will move east of the area within 
the next 1-2 hrs and we may see a dry period through the morning 
hours. Expect a left over boundary from convection over central 
Indiana yesterday evening to settle somewhere near the Ohio River 
over portions of southern Indiana and north central Kentucky. 
Believe this boundary will be key for redevelopment of convection 
this afternoon. 


Most short range models indicate a shortwave will dive south into 
the area this evening. Ahead of this wave, expect the atmosphere to 
become very unstable with only partly cloudy skies in the wake of 
morning convection. Bulk shear will increase ahead of the wave as 
early as 1-3pm this afternoon. This is when we may see convection 
begin to fire in the region of the left over sfc boundary. 
Convection should be enhanced in strength and coverage during the 
evening hours as the shortwave passes through. It is a bit unclear 
how long into the evening and overnight hours convection will 
continue. It may survive for a prolonged period of time if a good 
cold pool and outflow boundaries get going. At some point late 
tonight into tomorrow morning expect a break in showers/storms. 
Another notable shortwave looks to impact mainly northern Kentucky and 
southern Indiana with storms for thurs afternoon/evening as well. 
Models generally do not have a good handle on ongoing convection and 
evolution so confidence is rather low on exact timing. However, 
model soundings indicate increased bulk shear values with each wave 
and excellent instability so storms will likely be strong to severe 
in nature today through thurs with damaging winds, large hail, and 
torrential rainfall all possible. Pwats will hover in the 1.6-2 
inch range resulting in some heavy rainers and potential flood 
problems. 


As for temperatures, think that highs will range from the upper 80s 
to lower 90s today and tomorrow with locations west of I-65 likely 
seeing Max heat indices near 100 each afternoon. Low temperatures 
tonight will be mild in the lower 70s. 


Long term (thursday night through tuesday)... 
issued at 311 am EDT Wed Aug 20 2014 


Thursday night through Tuesday... 


Expect a hot spell throughout the entire extended period, at least 
through the middle portion of next week. 


In an upper air pattern that we've not seen much of this Summer, 
strong 500mb ridging will develop initially across the lower 
Mississippi Valley by Thursday evening, with longwave troughs 
located over the Pacific northwest and New England. The wavelength 
of this trough-ridge-trough pattern will lead to a stagnant pattern. 
The GFS for example holds this ridge in place through at least late 
Monday, building it northwards towards the commonwealth. We should 
expect probably a week's Worth of hot sticky humid weather with 
highs well into the 90s and warm overnight lows in the lower to mid 
70s over the weekend and into the middle of next week. Rising heat 
indices may be a concern for early next week. 


In this type of pattern, shortwaves moving along the periphery of 
500mb ridging can bring episodic convection. Initially, Thursday 
night through Sunday, scattered thunderstorms may develop within a 
northwest flow pattern along the northeastern edge of this building 
ridge. This would favor southeastern Indiana, southern Ohio and the 
northern Bluegrass for possible scattered thunderstorms, 
concentrated during the afternoon and evening hours. Southwestern 
Kentucky, closer to the warm temperatures aloft associated with this 
ridge, will likely stay dry. 


By Monday and Tuesday, think the entire region will be dry, as 
ridging builds northwards into the commonwealth.

Aviation (18z taf update)... 
issued at 125 PM EDT Wed Aug 20 2014 


Confidence in convective forecast this period is low, as cirrus 
shield from storms to our northwest quickly moves into the region. 
Have some cumulus developing over the central forecast area this 
hour, and Storm Prediction Center mesoanalysis indicates plenty of instability across 
the region. However, the cirrus canopy should provide some 
subsidence to inhibit convection. There is still a possibility that 
the storms to our northwest can remain organized enough to bring 
those storms to the terminals later this afternoon. Thus have gone 
with vicinity storms over a larger period of time and will update as 
the afternoon progresses. May even get into another round of precip 
later tonight, as additional disturbances move in from the 
northwest, but a lot will depend on what happens this afternoon. Fog 
forecast for Thursday morning will depend on that as well. Given 
very high dewpoints across bwg this hour, have enough confidence to 
go with a period of MVFR conditions, as in current guidance.
