Area forecast discussion 
National Weather Service Louisville Kentucky 
320 am EDT Thu Jul 31 2014 


Short term (now through friday)... 
issued at 300 am EDT Thu Jul 31 2014 


A broad immobile longwave 500mb trough continues over the Great 
Lakes, seemingly locked in place be bracketing ridges over the 
inland Pacific northwest and the eastern Atlantic. This trough will 
not move much during the next several days. 


Currently, a shortwave trough and corresponding inverted surface 
front is moving through northern Texas. This feature will continue 
to dig southeast around the longwave trough over the lakes. Rain and 
cloud cover will miss to our south, with widespread showers expected 
over Arkansas and southern Missouri late this afternoon, spreading 
east across the northern Gulf states by Friday afternoon. 


The commonwealth and southern Indiana will remain in a benign 
weather pattern for the next several days. A light pressure gradient 
will lead to nearly calm winds at night and light winds each 
afternoon. Expect westerly winds this afternoon at around 5 mph, 
becoming light northeasterly by Friday afternoon. High cloudiness 
associated with the Texas shortwave will erode by morning, with just 
some afternoon fair weather cumulus developing both today and Friday 
afternoons. Will continue just a slight chance of some isolated 
thunder Friday afternoon. 


Under the influence of a modifying trough, temperatures will rise a 
couple of degrees today and Friday, but still remaining a few 
degrees below normal. Highs will generally reach the mid 80s, with 
lows in the lower to mid 60s. 


Long term (friday night through wednesday)... 
issued at 318 am EDT Thu Jul 31 2014 


============================= 
long term synoptic overview 
============================= 


In the long term, a rather amplified upper flow pattern is expected 
to persist across North America with a ridge out over the western US 
and a trough over the eastern US. The Ohio Valley will remain under 
the influence of the upper trough early in the period. Some weak 
vorticity within the flow is expected to transverse through the base 
of the trough in the early part of the extended. As the weekend 
draws to a close, the upper trough is expected to lift out as the 
western Atlantic ridge will attempt to retrograde eastward into the 
eastern US. As this occurs, the upper ridge over the western US 
looks to close off. The Ohio Valley will reside in a cull between 
these two ridges early next week. However, these two ridge will 
link up by midweek resulting in more of zonal pattern developing 
across the eastern US. By the end of the period, the deterministic 
and ensemble guidance are in agreement with another strong vorticity 
lobe dropping into the northern US which will eventually render the 
flow back to a trough West/Ridge east pattern with the strong 
possibility of an upper level low getting cut off across the Ohio 
Valley. 


============================= 
Model preference & confidence 
============================= 


As for model preference, a 33/33/33 blend of the previous forecast 
and the 00z op GFS and 00z op Euro were used for the early part of 
the extended period (weekend period). For early to middle of next 
week, generally used a 50/50 blend of the op GFS and Euro along with 
their respective ensembles. A slightly higher weight was given to 
the ensemble solutions. Forecast confidence through the period is 
slightly above average with respect to temperatures and 
precipitation. We heavily leaned on the superblend guidance for 
temperatures through the upcoming period. 


============================= 
Sensible weather impacts 
============================= 


At the beginning of the long term period, we expect mainly partly to 
mostly cloudy conditions as we will be under the influence of the 
upper trough. With this feature in the region, scattered showers 
and thunderstorms will be possible Friday night through Saturday 
night. A marked decrease in activity is expected by Sunday as the 
upper trough lifts out. Overall coverage of convection is expected 
to be scattered at best and will probably not put a big Dent in any 
of our rainfall deficits. Drier and warmer conditions are expected 
as we move into early next week. Temperatures are expected to 
rebound to near seasonal normals from Monday through Wednesday. 
Daytime highs on Saturday will generally run from the upper 70s in 
the east to the Lower-Middle 80s in the west. Slightly warmer 
temperatures are expected on Sunday with mainly 80s. More 
seasonable middle to upper 80s are expected on Monday and Tuesday 
with upper 80s to near 90 expected by Wednesday. Overnight lows 
will generally be in the middle to upper 60s. 


A turn to more unsettled weather looks likely toward the end of the 
forecast period and into next weekend as the aforementioned upper 
level cut off low develops across the region. This would likely 
result in cooler temperatures returning to the area late next week.

Aviation (06z taf update)... 
issued at 100 am EDT Thu Jul 31 2014 


Despite weak troughing aloft, a relatively dry atmosphere and a lack 
of any disturbances will lead to clear to partly cloudy skies 
through the taf period. 


Pressure gradients will stay quite light through Thursday. Nearly 
calm winds through mid morning will become westerly at or below 5kt 
by this afternoon. 


Broken high cirrus over bwg will become partly cloudy by later this 
morning. Scattered afternoon fair-weather cumulus at or above 5k 
feet will develop this afternoon with VFR conditions continuing 
through early Friday.
