NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
912 am EDT Sat Jul 26 2014 


..forecast update... 
Issued at 910 am EDT Sat Jul 26 2014 


Quick update this morning, mainly to account for ongoing convection 
across Indiana. This area of convection has formed in a region of 
strong 925-850mb moisture transport. This moisture transport is 
expected to weaken through the morning hours as the low level jet dirunally 
weakens, and this is already beginning to occur as storms have begun 
to decrease in intensity on radar. Still think some of this 
activity may make it into the far northeastern County Warning Area (scott, Jefferson 
Indiana counties) before it dissipates, thus have added in pops 
there. Have also increased sky cover this morning for much of 
southern in/northern Kentucky. 


The thinking for this afternoon/evening remains largely unchanged. 
Still looks like we will have a lull in activity this afternoon, 
before more storms arrive this evening into the overnight hours. 
Will evaluate the 12z auite of data and have updates as needed. 


Short term (now through sunday)... 
issued at 355 am EDT Sat Jul 26 2014 


..increasing confidence for severe threat tonight through Sunday... 


Saturday: 


During the day today, the weather is expected to be relatively 
benign for much of the forecast area with clouds cluttering the 
skies as afternoon heating kicks in. Have kept much of the area dry 
with precip chances increasing as the evening hours approach. 
Southwesterly winds will also increase today as high pressure exits 
the region and allows for a tightening pressure gradient, thanks to 
a surface low pushing its way in behind it. Throughout the day, look 
for increasing warm, moist air to advect into the region, charging 
the atmosphere up for what's to come tonight. Expect highs to be 
much warmer than Friday, near or slightly above 90 degrees with 
higher dewpoints. 


Saturday night: 


As the headline indicates, severe potential for tonight appears to 
be likely over southern in and northern Kentucky. The primary question 
will be the timing of this well-advertised mesoscale convective system. Hi-res models are in 
general agreement of it entering the far western counties around 02z 
and plowing its way across the forecast area, affecting the 
Louisville and possibly Lexington Metro areas, before exiting 
sometime after 06z. The secondary question is how far east the 
severe threat will reach but it appears as though the mesoscale convective system will begin 
its decay after it gets through the Louisville Metro as it loses 
some of its support. Pwats increasing to around 2 inches, increasing 
low- to mid-level shear, 2000+ j/kg of MUCAPE, and steep lapse rates 
will all combine to create a damaging wind threat along with heavy 
rainfall. These parameters look to be their highest along and north 
of the I-64 corridor and west of I-65 in southern in. A few models 
are hinting at multiple rounds of weather even after the mesoscale convective system has 
paid a visit so have left mentionable pops through early Sunday but 
this activity, if it occurs, should remain below severe criteria. 


Temperatures will likely remain steady through the overnight period, 
only dropping down into the low to mid 70s. 


Sunday: 


The severe threat continues into Sunday with the focus shifting to 
the southern and eastern counties as a cold front approaches from 
the north. However, uncertainty remains in the details of how things 
will pan out as it will largely depend on early morning convection. 
If the mesoscale convective system does come through earlier in the evening on Saturday and 
no other development occurs, then model soundings are indicating 
that the damaging wind threat, heavy rainfall, and additionally hail 
will be a major concern. Classic inverted v soundings can be seen in 
the latest run of the GFS (00z), especially in southern Kentucky where the 
airmass will likely not be worked over. Stay tuned for more details 
as this time approaches. 


Highs on Sunday are currently forecast to be a degree or two cooler 
than Saturday but still reaching the upper 80s and low 90s, 
especially in the south. Even with cloud cover potentially lingering 
around from overnight convection, the warm air advection ahead of the front will be 
in high gear and should push up those temps regardless. Dewpoints 
will also continue to be on the high side - into the 70s. 


Long term (sunday night through friday)... 
issued at 320 am EDT Sat Jul 26 2014 


Showers and storms should be exiting south central and east central 
Kentucky sun evening at the beginning of the long term period. Some of 
these storms could be strong to severe in nature sun evening 
although it looks like the cold front will move through during the 
evening hours so any stronger storms should be moving out fairly 
quickly Sun night. A massive upper level trough will overtake the 
Midwest bringing another round of cool air. We'll see one more 
chance at some light rain showers over the area as energy along a 
secondary front pushes through the area Monday. 


Tues/Wed/thurs will be dry and pleasant as cool Canadian high 
pressure drifts south into the Midwest. Under mostly sunny skies, 
high temps will range from the mid 70s to the lower 80s with lows in 
the upper 50s and lower 60s. 


Shower/storm chances will arrive once again for Friday and through 
the weekend as the upper trough hangs over the Midwest with ridging 
over the western Continental U.S.. a split flow pattern will try to develop 
during the weekend possibly resulting in an upper low becoming cut 
off over the Midwest. Should this pattern pan out, several rain 
chances will be in store with unseasonably cool temps for next 
weekend.

Aviation (12z taf update)... 
issued at 652 am EDT Sat Jul 26 2014 


VFR conditions are expected to continue to prevail now through this 
evening but then becomes more questionable as an mesoscale convective system is expected to 
develop and directly impact southern in and northern Kentucky. Have 
continued to carry thunderstorms in the vicinity in this update for sdf given confidence in 
thunderstorm activity in and around the terminal. Additionally, have 
introduced thunderstorms in the vicinity mention in the Lex taf to account for the mesoscale convective system to 
track into the Bluegrass region. However, less confidence exists for 
the exact timing as these systems have a tendency to accelerate 
beyond what the models are able to capture. For this update, have 
bumped up the time frame by an hour, putting sdf in the 03z-07z 
range and Lex in the 05z-09z time frame. Bwg should escape direct 
impact from this mesoscale convective system but could still see some concerns to aviation 
interests as it brushes past to the north. 


By midday Saturday, the pressure gradient will tighten over the Ohio 
Valley as a surface low vies to move right on in behind an exiting 
high pressure, approaching the southern Great Lakes from the plains 
by the end of this taf period. Winds for much of Saturday are 
expected to be greater than 10 knots and from the southwest, gusty 
at times. Winds could briefly die down as the sun sets at sdf but 
are anticipated to pick back up with the approaching mesoscale convective system.
