Area forecast discussion, May 11, 2:33 PM EDT, 52 minutes before
AREA FORECAST DISCUSSION National Weather Service Jackson KY 233 PM EDT Thu May 11 2017 .SHORT TERM...(This evening through Friday night) Issued at 233 PM EDT THU MAY 11 2017 Current conditions across the area feature the main threat across eastern Kentucky being a moist and unstable air mass setting up over Kentucky ahead of a slowly inching south cold front. Surface instability has been sufficient enough to get some showers and a few storms to develop and slide east southeast. Later this afternoon into the evening, an MCV present over IN will shift east providing a bit more upper level support but the overall limiting factor despite decent shear, instability, and weak forcing will be the shallow lapse rates with this set up. Thus heading into this evening, the main area of concern will slide south and southeast KY being the area to watch since some decent sunshine occurred today as well. Will expect to see a few strong and possibly a severe storm or two. Heading into later tonight, the concern shifts to more of a flood concern. Any training activity this evening will leave a saturated boundary layer with additional rain moving in on Friday as the low out west lifts northeast bringing through a second cold front and increased shower and thunderstorm activity. The persistent ascent and PWATs in the 1.20 to 1.40 range will continue to present a flood threat. Will continue to mention this in the HWO through the day on Friday. The convection finally weakens Friday night as the front shifts off to the east. .LONG TERM...(Saturday through Thursday) Issued at 212 PM EDT THU MAY 11 2017 A few rain showers could hang on into southeast Kentucky Saturday morning. Otherwise, dry weather should return by midday and last through the remainder of the weekend as mid level ridging spreads over the area. A back door cold front may make a run at the area on Sunday, but not very good model agreement on whether showers will make it this far west, so kept the weekend dry. Ridging will strengthen into early next week with milder weather returning to the area as highs climb back into the 80s. The ridge may break down by Thursday allowing for our next chance for a few showers or storms. All in all, a pleasant stretch of spring weather is ahead. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) ISSUED AT 136 PM EDT THU MAY 11 2017 A low level very unstable air mass and moist as well has lead to some shower and thunderstorm development early this afternoon. Thus a few TAF sites have some MVFR cigs with the cumulus development. This activity will lift a bit as a front slides southeast bringing a few rounds of showers and thunderstorms. Will expect some IFR cigs tonight at each of the sites with this activity and continuing through tomorrow morning. Expect them to lift a bit heading into the late morning tomorrow. Winds will be variable at most locations until increasing from the west and northwest as the front slides south. && .JKL WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...SHALLENBERGER LONG TERM...KAS AVIATION...SHALLENBERGER
