364 FXUS63 KJKL 250700 AFDJKL AREA FORECAST DISCUSSION National Weather Service Jackson KY 300 AM EDT Tue Oct 25 2016 .SHORT TERM...(Today through Wednesday) Issued at 300 AM EDT TUE OCT 25 2016 Mid level ridge axis will slowly work eastward over the next 24 to 36 hours, keeping our weather dry through Wednesday. Temperatures have settled into the 30s in the colder valley locations early this morning. Despite the chilly start to the day, afternoon highs should rebound nicely with 850mb temperatures a degree or two higher than yesterday. This will put highs generally into the mid 60s across northern Kentucky to around 70 in southern Kentucky. Model soundings show some very dry air just off the surface that will likely mix down into the afternoon and evening hours with dewpoints crashing to around 30. While the ridge will start to move east of the area tonight, we should remain under its influence and would expect at a minimum for valley locations to decouple. Given the drier air in place, it seems reasonable that a few of the eastern valleys could approach the freezing mark. However, it appears temperatures for most will stay in the mid to upper 30s with lower 40s on the ridges. While temperatures may stay above cross over temperatures tonight, limiting fog or frost formation, we are close enough to freezing in some of our far eastern valleys to include a mention of some patchy frost late tonight. By Wednesday, heights continue to build with 850mb temperatures warming to just over +12C. This would support highs into the low to mid 70s, making for another beautiful eastern Kentucky fall day. Went slightly under guidance for dewpoints on Wednesday as models are bringing moisture back into the area much too fast, despite the southwest winds. .LONG TERM...(Wednesday night through Monday) Issued at 300 AM EDT TUE OCT 25 2016 Long term discussion will follow shortly. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) ISSUED AT 123 AM EDT TUE OCT 25 2016 Mainly VFR conditions and light winds will be seen through Tuesday night.
