..Forecast update... 
issued at 900 PM EDT Tue Sep 2 2014 


Last night's convective complex over southern Indiana and southern 
Illinois has essentially fallen apart as it moved southeast of the 
Ohio River. One area of stratiform showers and rain will still move 
through the Louisville area between 9 and 10 am. However, rainfall 
amounts will only amount to a spotty quarter to one half inch. 


The outflow boundary from last night's convection will serve as a 
focus for renewed convection across south central Kentucky and 
perhaps the southern Bluegrass region as early as late morning to 
around noon. Areas along and north of Interstate 64 has been worked 
over. Do not expect many strong storms there. However, robust storms 
still possible along and generally southeast of the Cumberland 
Parkway later today. 




Short term (now through wednesday)... 
issued at 305 am EDT Tue Sep 2 2014 


A tricky forecast for the next 18 to 24 hours as the remains of a 
convective complex roll into the area, and ultimately decide what 
type of weather we see later this afternoon and evening. 


Current radar imagery shows a convective complex that has developed 
ahead of a shortwave over the eastern plains. Clusters of strong 
storms stretch from southeast Kansas up through west central Indiana at 
this hour, with a heavy rain threat also in play. The storms are 
staying somewhat organized in an environment characterized by mu 
cape values in the 2000-3000 j/kg range, and 0-6 km bulk shear 
values in the 40-45 knot range. The environment over our County Warning Area is less 
conducive from an instability standpoint, however the corridor over 
stronger deep shear layer values (35-40 knots) will slide across 
southern Indiana and north central Kentucky through the late morning. As a 
result, expect scattered to numerous showers and a few rumbles of 
thunder from the decaying complex to slide across our north around 
dawn through mid morning. Some scattered showers may develop with 
the nose of a low level jet lifting northeastward after 4 am across our north 
as well. 


Expect a relative lull in action from the late morning to the early 
afternoon as morning activity dies and pushes east. However, by mid 
afternoon concern for redevelopment along the remnant 
outflow/differential heating boundary comes into play. This would most 
likely occur east of the I-65 corridor where best instability on the 
order of 1000-2000 j/kg of sb cape will line up with 0-6 km shear 
values around 30-35 knots. Redevelopment of storms will be 
conditional upon the morning convection. Given help from a mid level 
wave passing through the mean 500 mb flow, do feel we'll see the 
redevelopment and a few multicell clusters capable of gusty winds 
are possible. Storm Prediction Center has continued the low-end slight risk for eastern 
portions of our County Warning Area to account for this. Will mention potential for 
a few strong storms and gusty winds in the hwo, but overall won't 
play today's severe scenario up too much due to the conditional 
nature and small time window for severe to occur. Look for highs 
only topping out in the low and mid 80s. 


Convective activity should quickly diminish around sunset as mid 
level support exits to the east and we lose daytime heating. Will 
keep some lingering small pops across our south and east until the 
early morning hours. Otherwise, expect surface high pressure 
building in behind the system and skies becoming mostly clear across 
the northern half of the County Warning Area. This will allow lows in the upper 60s 
north to around 70 south. 


Wednesday should be mostly dry with surface high pressure in control 
and only a small chance of diurnally driven convective development 
across our south nearer the remnant boundary. Temperatures should be 
slightly warmer with highs more solidly in the mid to upper 80s. 




Long term (wednesday night through monday)... 
issued at 305 am EDT Tue Sep 2 2014 


Overall model agreement is present in extended range models through 
this coming weekend. Persistent mid-level ridge will remain anchored 
over the southern third of the U.S. For the second half of this 
week, with the ridge poking northward across the Tennessee and lower 
Ohio valleys. Then as stronger mid-level flow pushes east and 
southeast over the Great Lakes this weekend, a decent cool front 
will move southeast through central Kentucky and southern Indiana 
bringing lower humidity and cooler air temperatures for late in the 
weekend into early next week. 


In the day to day weather, the extended period should start off dry 
Wednesday night as surface high pressure overhead slides to the 
east. Models hint that some dying scattered convection could 
approach western parts of our area late Wednesday night associated 
with weak warm advection on the back side of the high, but will keep 
dry conditions in forecast. As better low-level moisture and higher 
surface dewpoints return Thursday, isolated to scattered diurnal 
convection is expected in the afternoon, with best chance north on 
the periphery of the upper ridge. Highs Thursday will reach the 
upper 80s and lower 90s. 


Any cells Thursday should weaken Thursday night given limited or no 
forcing and nocturnal cooling. Then on Friday, scattered diurnal 
convection should again develop with the best chance north half 
again, aided by the approaching cool front from the north. With 
soundings suggesting rather steep low- and mid-level lapse rates and 
lack of saturation, any storms that form in this environment would 
be pulse cells capable of gusty downdrafts and a decent amount of 
cloud-to-ground lightning. 


Scattered to perhaps numerous showers and thunderstorms will 
accompany the front as it drops southeastward across Kentucky on 
Saturday. The combination of clouds and showers will keep 
temperatures lower on Saturday - around 80 in southern Indiana and 
mid 80s in south-central Kentucky. The front will push though the 
state Saturday night. Precipitation will sag southeast Saturday 
night as well and be through much of our forecast area on Sunday, 
although a few showers could linger over southern and eastern 
counties of central Kentucky. Dry weather then takes hold Sunday 
night and early next week. 


The air behind the front will be cooler with Max temperatures Sunday 
into early next week a couple or few degrees below normal, mainly 
from the upper 70s (southern Indiana on sunday) to lower 80s over 
much of the area into early next week, with some mid 80s over 
south-central Kentucky by early next week. Lows will be in the 60s 
Sunday morning through Tuesday morning, with some 50s expected 
Monday morning. Dewpoints and humidity levels will drop as well 
behind the front. 


However, looks like the humidity and higher dewpoints will once 
again rise by mid next week as another weather system approaches at 
that time imports warmer, more moist air from the south into 
Kentucky.

Aviation (12z taf update)... 
issued at 650 am EDT Tue Sep 2 2014 


Convective complex is currently oriented from SW to NE just north of 
the Ohio River and will continue to push east at about 40 knots as 
it decays. Have noticed a marked decrease in lightning over the past 
two hours, although a few strikes are still expected. Best timing 
into sdf will be around 730 am EDT, where 4 miles in rain showers and 
occasional rumble of thunder are expected along with a west-southwest wind 
shift. Thinking rain showers could prevail until around 10 or 11 am. Expect 
the same time frame at Lex only delayed an hour for onset and exit. 
Won't mention thunder at Lex this morning as complex should be 
almost entirely decayed by the time it gets there. Bwg will miss the 
first wave and shouldn't expect any showers until late morning. 


There should be a lull after the initial morning precipitation 
chances, then convection is expected to fire in the early afternoon 
along the remnant outflow/differential heating. This is expected to 
be between sdf/Lex and east of bwg, although isolated thunderstorms 
could be around all terminals through the afternoon and early 
evening. Expect convection to die around sunset with some lingering 
clouds. 


Winds will gradually veer to SW and then west-southwest through the day, 
staying up around 10 mph. Once winds slacken late this evening, they 
will return to south-southwest.
