NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
653 am EDT Wed may 27 2015 


..updated aviation discussion... 


Short term (now through thursday)... 
issued at 310 am EDT Wed may 27 2015 


..strong to severe storms possible this afternoon/evening... 


A few sprinkles were moving east over east central Kentucky early this 
morning. Other than this very light/isld precip, the rest of the 
area was dry with skies becoming mostly clear to partly cloudy west 
of I-65. Expect that we'll continue to see sky cover slowly 
decrease through the morning hours especially after sunrise. Before 
sunrise low stratus and light patchy fog will be possible over 
portions of south central and east central Kentucky. 


The next chance for showers/storms will arrive this afternoon as an 
upper level shortwave trough passes through the Midwest. The latest 
NAM/GFS indicate the wave will be stronger and better organized to 
our north, but we'll still see modest forcing and decent low to mid 
level flow resulting in around 30-35 kts 0-6km bulk shear. If skies 
go mostly sunny to partly cloudy for a good portion of the morning 
and early afternoon as predicted, we'll likely see a good amount of 
sfc based instability build up...around 2000+ j/kg. Steep low and 
mid level lapse rates will exist too. For these reasons, think that 
damaging winds will certainly pose a threat today in storms that get 
going in our area especially along and north of I-64 close to the 
best forcing from the upper level shortwave. Hail up to around 1 
inch will also be possible. Boundaries from storms that initiate to 
our north-northwest may also provide a trigger for storms in our area this 
afternoon/evening. 


Storm clusters should wane and move east of the area by late evening 
with only small storm chances for the rest of tonight. 


Thursday small chances for showers/storms will continue as we remain 
in a moist, unstable environment. However, an upper level ridge 
moving through the area will certainly work to suppress convection 
somewhat. With a weaker flow, would expect isld to sct pulse-like 
storms to bubble up in the late afternoon/evening hours thurs 
although some short range models keep US mostly dry thurs. 


Temperatures should be a tad warmer today than yesterday with highs 
in the 82-86 degree range. Lows tonight will remain mild in the 
lower 60s. Highs thurs will warm into the 84-88 degree range. 


Long term (thursday night through tuesday)... 
issued at 250 am EDT Wed may 27 2015 


The main focus in the long term is on precipitation chances as a 
moist and seasonably warm air mass holds over the lower Ohio Valley. 


Thursday night into Friday the synoptic pattern is expected to 
feature a longwave trough from the Southern Plains through the Great 
Lakes while a ridge remains across the southeast US. The local area 
will be on the periphery of both of these features. Models remain 
consistent showing that the ridge will build slightly and in the 
absence of any shortwave trough, this period is our 'driest' with 
only slight chances for afternoon and early evening showers/storms. 


More synoptic influence and dynamics are expected Saturday into 
early Sunday as a shortwave trough, seen currently in water vapor 
imagery off the coast of California, treks through the southwest US 
and Southern Plains. This system will brush our northwest Saturday 
afternoon, enhancing mid/upper level lift. Closer to the surface, a 
slow moving front will approach as well. Moisture pool and pwats 
climb along/ahead of the front and with the greater lift, expecting 
more widespread showers and thunderstorms. 60 to 70 percent pops 
look good at this time. 


Model uncertainties and differences arise Sunday into early next 
week as to how progressive this boundary pushes south. 27.00z GFS 
was the most aggressive, clearing the front through the entire 
forecast area Sunday into Monday, while the Gem and European model (ecmwf) held it up 
right through central Kentucky. Where the front clears through, 
north/northeast flow could bring much drier and somewhat cooler air 
in its wake, while to the south, the moist/warm air mass will 
remain. By Monday night, guidance pulls this front back north, 
bringing back the warmer and more moist conditions. 


Temperatures through Saturday are expected to be relatively 
persistent with highs in the low 80s and lows in the mid/upper 60s. 
Sunday Onward is less certain, but if/where the front comes through 
then cooler temperatures may prevail. For now, a model consensus of 
highs in the upper 70s and lows in the 60s seem reasonable.

Aviation (12z taf update)... 
updated 650 am EDT Wed may 27 2015 


Low clouds and light br may affect Lex/bwg for a few more hours this 
morning before conditions return to VFR. 


Another upper level disturbance will bring showers/storms this 
afternoon/evening. MVFR/IFR flight restrictions will be possible in 
any storm that hits a taf site. Did not include in the taf attm 
since T-storm coverage is expected to be scattered this 
afternoon/evening. Will continue thunderstorms in the vicinity in the tafs and better time 
convection out with a coming taf issuance. 


Winds will be light south-southwest early this morning and more SW for the 
daylight hours today. Winds may gust up to around 15-18 kts today. 
Higher gusts will be possible in convection.
