Area forecast discussion National Weather Service Louisville Kentucky 1223 am EST Thu Dec 18 2014 ..updated aviation discussion... Short term (now through Thursday night)... issued at 250 PM EST Wed Dec 17 2014 ..light wintry precip late tonight and Thursday morning... A shortwave trough now over southeast nm will advance toward MO by daybreak Thursday. Current precipitation over OK and northwest Arkansas will move toward US as well, bringing light precip to the southwest half of the forecast area after midnight. This precip will have to overcome some dry air initially at low/mid levels of the atmosphere, but expect this to happen in the 08-13z window. Temperatures will be cold enough for a wintry mix of precipitation, as clearing skies this afternoon should, despite upper clouds thickening this evening, allow for several hours of good radiational cooling conditions through the evening hours. Thus by midnight, many areas getting this precip should get down to around 30 degrees. The cold layer aloft may be deep enough to allow for either snow or sleet, but a few model soundings show enough warm air aloft that freezing rain cannot be thrown out of the mix yet. In addition, winds will be light enough and the coldest air remaining over our southeast counties may be moist enough for some patchy freezing fog to occur ahead of any precip. Lots to watch for in other words. The saving Grace here is the dry air aloft evaporating a lot of the precip as well as the short duration of the event, keeping quantitative precipitation forecast light. Have an area of half inch accumulations for snow along an axis from Hartford, Kentucky to roughly Glasgow. Also have a few hundredths of ice accumulations. These light values warrant issuing a Special Weather Statement highlighting these threats. The rest of the day Thursday should remain cloudy and cold, with highs stuck in the 30s. Diurnal curves will be narrow for temperatures as cloud cover sticks around Thursday night as well, leaving lows in the mid to upper 20s. Long term (friday through wednesday)... issued at 302 PM EST Wed Dec 17 2014 The synoptic pattern at the start of the long term period will feature a ridge across the western conus, with a downstream trough across the south-Central Plains. This trough will deamplify as it pushes into the Ohio Valley this weekend. A more substantial, anomalous trough will then build into the Ohio Valley towards the end of the period (around Christmas eve). The main focus of the long term period continues to be on the upcoming weekend system, slated to move through the region Friday night into Saturday. The latest model guidance has continued to trend weaker and further south with this system. The 17/12z operational NAM is the most aggressive with quantitative precipitation forecast into the Ohio Valley, owing to the fact it is a bit more negatively tilted and stronger with the mid-level shortwave and associated surface low. However, the European model (ecmwf)/GFS/Gem solutions, along with the 17/15z sref solutions, depict more of an open, positively-tilted shortwave which keeps the system more suppressed and weaker. Looking at the forcing, it appears the better moisture transport and frontogenetical circulations will be well south of the Kentucky border. A coupled jet structure, with a rapidly weakening northern stream branch, will be the main driver of precipitation this far north, which means amounts/rates should remain light. Given the agreement of these solutions and rather meager forcing progs, have trended the forecast drier and further south. What this means for the sensible weather in the Ohio Valley is less in the way of impact, and more of just a glancing blow of perhaps some light wintry precip. Model soundings still differ a bit on their solutions, with some even suggesting some light sleet mixing in as this system passes, but will leave that out of the forecast for now. Some minor snow accumulations, mainly on grassy surfaces, still appear possible generally along and southeast of a line from Leitchfield to Richmond. Further northwest, some light snow may fall, but do not expect much in the way of accumulations given the light quantitative precipitation forecast and poor rates to overcome warm grounds/roads. Once this system passes, high pressure will build into the region Sunday into Monday. However, by Monday night, an anomalous trough will be diving into portions of the central conus, with a surface low expected to rapidly deepen somewhere over the eastern United States. Ensembles and long range deterministic guidance have been hinting at this system for days, so confidence is high in a significant storm somewhere over the eastern Continental U.S.. however, details continue to remain murky on whether this system will impact the Ohio Valley in the form of rain, snow, or a wintry mix. For now, taking an ensemble approach, it appears this system will be mostly rain on the front side Monday night into Tuesday, changing to snow as cold air quickly filters in Tuesday night into Wednesday. Given the impact on the Christmas Holiday, this is certainly a system we will continue to monitor closely. && Aviation (00z taf update)... issued at 1215 am EST Thu Dec 18 2014 Wintry precipitation associated with a weakening Southern Plains storm system will almost completely dissipate prior to reaching sdf and Lex. For these two sites, expect only some flurries or light sprinkles after 14z this morning at worst. Light snow or light mixed precipitation is possible at bwg beginning around 10z and continuing through 15z. MVFR visibilities and ceilings will develop if any of this occurs. After light precipitation ends, expect MVFR ceilings later this afternoon. Over the next couple of hours, sdf and Lex will lie near the southern edge of an extensive MVFR shield of strato-cu. Based on satellite imagery, think that sdf will trend towards VFR ceilings by around 07z, with Lex ceilings rising to VFR by 08z. Winds will stay generally from the north overnight and Thursday at around 4 to 8kt. && Lmk watches/warnings/advisories... Kentucky...none.
