NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Louisville Kentucky 
845 PM EST Sat Dec 20 2014 




..forecast update... 
Issued at 840 PM EST Sat Dec 20 2014 


I got burned by rapid erosion of stratocumulus, so have updated taf 
for ksdf. It's not altogether unexpected...just put too much Faith 
in the very narrow saturated layer around 025 agl, but with no 
dynamic forcing, diurnal subsidence prevailed. Klex is still on the 
edge of this cloud shield. Will hold off there for now, but update 
likely there as well, along with tweaks to sky grids. 


Short term (now through Sunday night)... 
issued at 200 PM EST Sat Dec 20 2014 


The synoptic pattern this afternoon features a quasi-zonal upper 
level flow east of The Rockies while an active northern and southern 
jet moves across the West Coast. A few weak shortwaves have been 
moving through the flow across the Great Lakes and Ohio Valley, 
which were responsible for this morning's light snow. At the 
surface, weak high pressure is loosely centered northeast of the 
area. Temperatures are running around 5 degrees below mid-December 
normals, mainly in the mid 30s to lower 40s. 


A dry evening/night is in store for the area with the main forecast 
challenge cloud cover. Subsidence in the wake of the departing upper 
level shortwave and drier mid levels should keep clouds variable. 
Areas along/south of the Kentucky parkways are likely to see more clearing 
while southern Indiana locations should be partly to mostly cloudy. 
Lows will vary greatly depending on where clear pockets develop, but 
are expected to range from the mid 20s to the lower 30s. Patchy 
light fog may develop across southern/central Kentucky due to the light 
wind field, residual low level moisture and expected clearing skies. 


For Sunday, much of the day we'll be under the influence of high 
pressure as it slowly moves to the northeast. Plan on light 
easterly/northeasterly winds and high temperatures in the mid 40s. 
Southeasterly to southerly flow develops Sunday night with weak warm 
air advection beginning. Clouds will be on the increase during the 
night from south to north and with the boundary layer remaining a 
bit more mixed, lows will only fall into the mid/upper 30s. 


Long term (monday through saturday)... 
issued at 315 PM EST Sat Dec 20 2014 


..active weather likely Christmas eve... 


Upper pattern will begin to amplify on Monday, and will open the 
door for a mild but unsettled first half of the week. Confidence in 
the overall pattern is fairly high, but limiting factors are in the 
sensible wx impacts on Monday and more in the timing thereafter. 


SW flow will deepen on Monday, but the best moisture feed will 
remain off to our west. Still could see weak isentropic lift with a 
warm advection Wing, so will hold onto a slight chance for some 
light rain. 


Increasing warm advection with pops continuing to ramp up Monday 
night and Tuesday. Leaned on the warmer end of guidance for temps, 
and that might not be warm enough. Will need to rely on the onset of 
rain and resulting wet-bulb effects to get temps below 50 on Monday 
night. 


Likely/categorical pops will run Tuesday into Wednesday, with the 
best chances centered on Tuesday night under a strong moisture feed. 
New uncertainty with the timing creeps in as the GFS tries to close 
off a 500mb low over the Southern Plains. This solution also tracks 
the deepening surface cyclone right up the I-65 corridor, which 
would enhance our chances for thunder. Will not jump on this 
solution at this time, but continue to trend slower and therefore 
warmer. Net result is temps in the 40s at 12z Wed, which will be our 
Tue night low and Wed high. This moves the window for a rain/snow 
changeover more into Wednesday evening, with minor snow accumulation 
possible Wednesday night if any snow showers are heavy enough as 
Santa makes his rounds. 


Precip should cut off before dawn on Christmas day, with mild and 
dry conditions late in the week as progressive upper ridging 
dominates. Next system works into the plains on Friday without 
really phasing the northern and southern streams. Will run chance 
pops Friday night into Saturday as the cold front pushes through the 
Ohio Valley. Temps close enough to freezing to keep an uncertain 
precip type near and north of the Ohio River, but confident in all 
liquid farther south.

Aviation (00z taf update)... 
issued at 1204 PM EST Sat Dec 20 2014 


Low VFR cloud deck roughly north of a Lex-sdf-evv line starting to erode 
in the west but cigs lowering to MVFR in the east. This pattern 
matches up well with NAM surface-850 rh, so will loosely base timing of 
sdf and Lex cigs on this, with improving conditions at sdf but 
lingering MVFR cigs though at least 06z at Lex. Only fly in the 
ointment is near-surface relative humidity of 90% at both sites lingering through the 
night, which could keep MVFR level cigs lingering. Winds at both 
sites north-northeast under 5 kts through the overnight hrs. 


With clear-scattered clouds at bwg, MVFR vsbys are a possibility, and with 
winds light and variable there, will continue going forecast of MVFR 
vsbys in fog developing.
