NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
346 am EDT Wed Aug 20 2014 


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 (06z taf update)... 
issued at 110 am EDT Wed Aug 20 2014 


The main taf concerns will be any light br this morning and 
convection timing. First of all, the convection in the area early 
this morning looks to impact perhaps the Lex taf with a rain shower 
over the next few hours before moving out of the region. Will need 
to keep an eye on the convective complex over central Indiana as it 
slowly makes progress southward toward sdf/Lex this morning. It is 
weakening and most short range models do not have it making it into 
these taf sites early this morning so will not include in the 
sdf/Lex tafs at this point although will watch closely. 


The next concern is light br formation around sunrise. Went ahead 
and backed off of vsbys some with this taf issuance as the mixy 
atmosphere with a 20 kt low level jet expected during the pre-dawn hours 
should limit fog density. Will hold bwg/Lex at MVFR conditions 
around sunrise and sdf at VFR. 


This evening another convective complex is expected to develop to 
our northwest and dive south/southeast into the area. Ahead of this 
complex of storms, additional cells may form over central Kentucky. Felt 
confident enough to include thunderstorms in the vicinity at the taf sites for this issuance 
as models have been persistent with this round of convection. 
However, timing may need to be adjusted throughout the day today. 


Winds will remain out of the south-southwest through the taf period generally 7 
kts or less except in T-storms.
