NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
249 am EDT Sat Sep 5 2015 


Short term (now through sunday)... 
issued at 243 am EDT Sat Sep 5 2015 


The synoptic pattern early this morning features broad ridging 
across much of the eastern Continental U.S.. however...a weak upper low/shear 
axis evident on WV imagery was near the Great Lakes region and will 
be the main focus of the period. 


All is quiet this morning as earlier convection has dissipated. The 
main forecast challenge today will be convective potential this 
afternoon/evening. The aforementioned upper level shear axis will 
persist across portions of in/Ohio today. Most 00z guidance 
initialized poorly with the convection that was ongoing 
yesterday evening...thus confidence is not overly high. That being 
said...a persistence forecast coupled with the hi-res WRF-arw (which at 
least had an idea of yesterday evening's convection)suggests a 
few storms will once again be possible mainly in central 
Indiana/southern Ohio early this afternoon along the shear 
axis...perhaps spreading south into the northern Bluegrass and southern 
Indiana later this afternoon into this evening. Forecast soundings out 
of ksdf show a strengthening cap around 600mb throughout the 
afternoon/evening...so think any convection will really struggle 
southwest of a line from Louisville to Richmond. Even where convection 
is possible...only subtle forcing both at the surface and aloft preclude 
anything more than slight chances at this time. Temperatures today will 
basically be a persistence forecast as 1000-850mb thicknesses look very 
similar to yesterday. Therefore...will go with highs in the low to middle 
90s once again. 


Dry conditions will prevail tonight with lows in the middle 60s to 
lower 70s. For Sunday...mid-level temperatures will 
really be on the rise as heights build across the Ohio Valley. 
Therefore...will go with a dry forecast except for the Lake 
Cumberland area...where capping won't be quite as strong and a 
westward moving shortwave may be just enough to spark an isolated 
storm or two. Low-level thicknesses come down just a bit on Sunday...so 
will go a degree or two cooler across the board. 


Long term (sunday night through friday)... 
issued at 245 am EDT Sat Sep 5 2015 


The question in the long term is when will the heat break and will 
we get better chances for rain. The first half of the work week 
looks to continue dry and above normal. Moisture will increase some 
on Wednesday...but we still have a question of how close a front 
will get to US to enhance afternoon thunderstorm chances. Given the 
increased moisture will continue to advertise widely scattered 
storms along and south of the I-64 corridor...but have gone a little 
higher for north of that based on the proximity to the front and 
better pool of moisture. 


The Prospect for a wet forecast looks better the second half of the 
work week...as that front and its associated pool of moisture 
lingers in the vicinity. We may not be able to get this front to 
clear the region until just beyond this forecast period...so have 
gone with a cooling trend in temperatures the second half of the week and 
probability of precipitation of 30-50 percent each day.

Aviation (06z taf update)... 
issued at 1254 am EDT Sat Sep 5 2015 


Earlier convection to the northeast brought an outflow boundary 
through ksdf and klex this evening. Behind this 
boundary...dewpoints have come down a bit which may help to limit 
fog/haze potential. Have kept in MVFR restrictions...but started them 
a bit later than the previous forecast. The boundary may help limit 
kbwg fog potential as well...but with the boundary likely washing 
out somewhere near the terminal...do not have the confidence to 
downplay fog potential just yet. Will leave in a tempo IFR group. 


Otherwise today will be more of the same...with any fog/haze quickly 
burning off and diurnal cumulus developing in the afternoon. A few 
isolated storms will be possible once again...but coverage too low 
to warrant mention in the tafs. Winds will be out of the east-southeast at 5- 
10 knots.
