NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
321 am EDT Sat Oct 25 2014 


Short term (now through sunday)... 
issued at 300 am EDT Sat Oct 24 2014 


Latest water vapor imagery combined with 500 mb heights shows broad 
ridging across the southern and Central Plains while a weak 
shortwave trough is pushing through the Great Lakes region. At the 
surface, a cold front lies across northwest Illinois, which is 
slated to pass through the forecast area later today. Southerly flow 
out ahead of this front has kept temperatures mainly in the middle 
to upper 40s with some of the sheltered, cooler spots dipping down 
into lower 40s. Patchy light fog has developed across southern and 
southeastern Kentucky thanks to a light surface wind field. 


For today, there is good agreement between the 25.00z guidance in 
regard to the frontal passage, which is expected to pass through 
mainly dry. Forecast soundings show the greatest moisture resides in 
the 950-850 mb layer, where some weak lift also is found. While 
the deterministic models are dry, some of the hi-res solutions 
/hrrr and nmm-east/ show what would likely be sprinkles moving 
across southern in and northern Kentucky by mid-morning. Not confident 
in the extent of this solution, so have continued dry forecast but 
could not rule out a brief sprinkle or two. Mostly cloudy skies 
this morning will give way to partly to mostly sunny skies later 
this afternoon as the front moves through and drier air builds 
into the region. Despite the early cloud cover, high temperatures 
look to reach the lower to middle 70s and overall it will be a 
pleasant late October day. Plan on mostly clear skies and 
seasonable low temperatures tonight, in the upper 40s to near 50 
degrees. 


Northwesterly flow aloft on Sunday with high pressure at the surface 
will result in another mostly sunny day with slightly above normal 
temperatures. The forecast area will be within a 850 mb temperature 
gradient, with the southwest areas likely to reach the middle/upper 
70s while the northeast region near 70 to lower 70s. 


Long term (sunday night through friday)... 
issued at 314 am EDT Sat Oct 25 2014 


Shortwave ridging Sunday night and low atmospheric moisture will 
keep skies mostly clear. At the surface high pressure will be 
edging off to the east, putting US in weak return flow by morning, 
which will help keep overnight temperatures up. Lows by Monday 
morning should range from around 50 in the Blue Grass (upper 40s in 
the usual cool spots) to the middle 50s west of I-65. 


Monday will be a pretty amazing day with sunshine and southwest 
breezes taking temperatures into the 80 to 85 degree range, courtesy 
of deep southwesterly flow between ridging to the east and a surface 
cold front and upper trof approaching from the west. Lows Monday 
night should be around 60 in the warm regime. 


Record Max for Oct 27 record warm low for Oct 28 
Louisville 84 (1940) 64 (1991 and 1984) 
Lexington 87 (1940) 64 (1984) 
Bowling Green 87 (1919) 65 (1984) 
Frankfort 89 (1940) 61 (1899) 


The aforementioned front will enter the picture Tuesday. Models 
have had a hard time pinning down the timing of this front, but 
after looking at the past several runs of the GFS plus the ec and 
Gem, as well as gefs plumes, it seems a fropa somewhere around 
Tuesday evening is likely. The recent trend of the models to speed 
up the front, after previous runs over the past few days tried 
slowing it down, may be an aberration. Regardless, we'll have 
increasing rain chances through the day Tuesday, peaking late 
Tuesday afternoon into Tuesday evening, and then decreasing towards 
Wednesday morning. The best dynamics will be to our north with this 
system, but we should still have enough instability and shear for 
some thunderstorm development. Depending somewhat on just how much 
sun we get Tuesday, southwest winds could gust into the 20-25mph 
range by afternoon. High temperatures Tuesday will also depend on 
clouds and rain, but right now will go for 70s in the forecast. Lows 
Tuesday night will range from the mid 40s in southern Indiana to 
lower 50s around Lake Cumberland. 


Wednesday and Wednesday night are looking generally dry as high 
pressure moves through. Look for highs in the lower 60s and lows in 
the lower 40s. 


An upper level disturbance will slide overhead Thursday 
afternoon/evening, but will be starved for moisture so will keep 
pops very low. 


The new European model (ecmwf) has come in with a radically new, wet, solution for 
Friday, but it's much too soon to jump on that so will stick with a 
dry forecast (in line with the gfs) for Friday.

Aviation (06z taf update)... 
updated at 110 am EDT Sat Oct 25 2014 


A weak cold front will pass through the region today with little 
aviation impact to the taf sites outside of a period of broken 3-4 
kft ceilings from mid morning through early afternoon. Ahead of this 
front though, weak high pressure and light winds will result in a 
period of fog at bwg until around 13z. Continued previous forecast 
for brief period of IFR visibilities but as the night continues, 
forecast soundings show the deep light wind layer eroding as the 
front approaches, so not expecting conditions lower than 2sm. 


Otherwise, plan on a wind shift from southerly to westerly later 
this morning at bwg/sdf/Lex, then eventually to the northwest late 
in the period as the front sweeps through. Skies look to clear by 
mid afternoon as a much drier airmass filters across the region.
