NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
925 PM EDT Sat Sep 20 2014 


..forecast update... 
Issued 924 PM EDT Sat Sep 20 2014 


Did a quick update to simply bring hourly T/TD values closer to 
currently observed values. Also made some adjustments to the pop 
forecast overnight. Specifically, made minor adjustments to 
precipitation arrival...in that showers and storms will arrive a 
little later than expected. Showers and storms will be possible 
across southern Indiana after midnight EDT. Showers and storms will 
be possible across our Kentucky very late tonight...most likely toward 
sunrise Sunday morning. 


Short term (now through Sunday night)... 
issued at 250 PM EDT Sat Sep 20 2014 


SW return flow is well established over the Ohio Valley as high 
pressure retreats off the Delmarva coast, and a cold front dives southeast 
across the land of Lincoln. Temps have punched into the lower/mid 
80s with dewpoints solidly in the 60s, in a definitive last hurrah 
for astronomical Summer. Modest enhancement in the cu field over 
southern Indiana has generated a few isolated showers, but even the 
traditional 20 pop is a bit generous to describe their coverage. 


The heat of the afternoon will keep the isolated showers in play 
until around sunset, and there is enough enhancement in the cu that 
north-central Kentucky would be fair game as well. However, there 
remains a strong enough mid-level cap that any showers could not 
grow very tall, so no mention of thunder. 


Low-level jetting overnight will keep temps unseasonably mild. Given 
the typical model bias in pre-frontal SW flow, will keep forecast 
temps at least a couple degrees warmer than the warmest of the model 
guidance. Main bust potential would be anywhere that it rains before 
daybreak, as wet-bulb effects would knock temps down closer to model 
guidance. Confidence in precip is again quite limited, as model quantitative precipitation forecast 
fields are backing off in response to the track of the upper impulse 
remaining to our north. Will go above guidance pops with 30-40 pop 
north and just a slight chance over south central Kentucky, but quantitative precipitation forecast 
looks quite meager. 


Best rain chances on Sunday will be across southern Indiana early in 
the morning. The cold front could dry up as it pushes southeast, as 
the dynamics are not as favorable farther south. Fropa will be 
around the time of minimum instability, but with decent mid-level 
lapse rates and a 30-40 kt low-level jet at 925mb, will at least 
mention isolated thunder. Pops never go above slight chance south of 
the western Kentucky Parkway and west of I-65. 


Decent cold air advection will set up behind the front. However with 
deep boundary-layer mixing and decreasing cloudiness, we do expect 
at least some diurnal temp recovery. Sunday night mins will be above 
guidance once again, as the north-northwest winds stay up around 5-7 kt. 


Long term (monday through saturday)... 
issued at 300 PM EDT Sat Sep 20 2014 


Upper air pattern will set up Monday through the entire work week to 
bring a remarkable stretch of fine late September weather that, all 
told, will probably last a full week or more. In fact, 500mb heights 
over the Northern Ohio valley from Wednesday onwards will rise to 
values more typical of Summer than early fall. 


Basically, this fundamental shift in the pattern aloft will begin 
Tuesday as a deep upper trough develops off of or near the Pacific 
northwest coast. Due to the configuration of the northern 
hemispheric flow, this trough will move very little, possibly coming 
ashore the Pacific northwest coast late Friday. Strong 500mb ridging 
will develop over Indiana or Ohio Tuesday and will remain nearly 
stationary through probably at least Saturday or Sunday of next 
week. 


Now for the details... 




Expect a rain free week with the first real chance of precipitation not 
really apparent until a week from tomorrow. 


High pressure building across the upper Midwest early Monday will 
bring northerly winds and a cool day Monday, despite ample sunshine. 
Temperatures Monday will struggle to reach 70, especially across 
southern Indiana and the Bluegrass region. After a clear night with 
light northeast winds and good radiational cooling, Tuesday morning 
will be chilly, with the coolest early morning lows of the season so 
far. Some typically cool sheltered rural locations may approach 40 
for a low early Tuesday. Tuesday will warm into the lower 70s under 
ample sun and light east winds. 


Wednesday through Friday will be mostly clear with a slow warming 
trend. Stationary high pressure over Ohio throughout this period 
will bring light winds and several days of relatively wide diurnal 
temperature swings. Expect warm afternoons with coolish nights. 
Highs will warm from the mid 70s to the lower 80s, with lows in the 50s. 


Clear to partly cloudy skies, slightly higher humidities and warm 
temperatures are anticipated next weekend. Deep layer moisture will 
return to the Tennessee Valley with some chance of afternoon or 
evening thunderstorms. However, for now, will continue with a dry 
forecast as drier air is still expected to hold over the 
commonwealth. Temperatures this weekend will not stay warm, with 
highs near or in the lower 80s.

Aviation (00z taf update)... 
issued at 709 PM EDT Sat Sep 20 2014 


Cluster of convection east of kbwg will continue to slide off to the 
east and weaken over the next hour. VFR conditions are expected at 
the terminals this evening and into the overnight hours with a 
breezy southwesterly surface flow continuing. 


While kbwg did pick up some precipitation this afternoon, current 
thinking is that low-level jet cranking up overnight will prevent 
fog formation down that way. However, will continue to monitor for 
a possible amendment later if fog developers. 


Surface cold front will approach from the northwest tonight. Model 
time height sections continue to show a light southwesterly flow at 
the surface with a low-level jet developing after midnight. 
Therefore, will keep low level wind shear in the tafs going for this update as 
current forecast looks good. Did add some vcsh at the terminals for 
late tonight and toward daybreak Sunday as the cold front swings 
through the region. Surface winds will then shift to the west and 
northwest Sunday morning as the cold front slide southeastward 
across the region. Surface wind gusts of 15-20kts will be common at 
the terminals on Sunday.
