Area forecast discussion, Oct 10, 1:28 PM CDT, 5 hours 9 minutes before
Area Forecast Discussion National Weather Service Paducah KY 128 PM CDT Tue Oct 10 2017 .SHORT TERM...(Tonight through Thursday night) Issued at 119 PM CDT Tue Oct 10 2017 Visible satellite imagery and surface observations show the cold front on our western doorstep already, but it has been standing in place there for the past 2-3 hours, awaiting its upper energy push that will propel it on across our FA. This will come later this afternoon/evening. Meanwhile Laps data does show that wedge of breakout clouds has allowed MUCapes to rise into 1500 ish J/KG range, with upwards to nearly 2500 just to our south. This area may be short-lived however, as additional dense cloud cover is nearby. We'll thereby have a short window for strong/svr storm, still in Marginal risk. Fropa brings gusty shift to west/northwest winds and then drier/cooler air replaces our almost summer like warm/humid airmass for the next couple days thereafter. Dew points some 15-20F cooler are poised to usher across the FA. .LONG TERM...(Friday through Tuesday) Issued at 119 PM CDT Tue Oct 10 2017 Ridging upper heights/high pressure will bring warming profile as we head into the weekend. The next cold front takes shape and makes passage Sunday afternoon and evening. Models are synchronizing on this solution so we made only minor massages to the overall long term forecast. Mainly, we direct Pops to along/ahead of the front, ie mainly Sunday-Sunday night. In addition, the preceding warm up, we bump up a degree or two from the mean/blend, as well as the post frontal day 1 cooldown, where we shave off a degree from the mean/blend. 80s/60s will be replaced by 70s/50s, similar to the short term frontal passage. && .AVIATION... Issued at 119 PM CDT Tue Oct 10 2017 Satellite shows some break in the clouds but still plenty of flight restricting bases scattered to broken across all terminals. A cold front is poised just west of SEMO attm, and will be making passage this evening. A chance of showers/thunderstorms with IFR restrictions to both cigs/vsbys may accompany its passages. Winds will shift to the west/northwest and gust upon passage. Time/heights and mos suggest lingering low layer RH may result in fog or low stratus type post frontal environ late tonight-early tmrw, even with light nwlys. We'll hint at that as well. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...None. MO...None. IN...None. KY...None. &&
