(Today through Thursday) Issued at 506 AM EDT WED MAR 21 2018 The main low pressure system is progressing eastward, but looks to redevelop past the Appalachians. With this transition, the HRRR as well as the RAP model show rising heights over eastern Kentucky. This means subsidence is taking over, leading to diminishing precip through the morning and early afternoon. Will continue with current advisories, but with lighter accumulation than expected in most areas, have lowered overall QPF and snowfall amounts. The highest snowfall amounts are still forecasted to occur in higher elevations above 2000 feet, but mainly in the southeastern terrain. Lingering snow showers will persist late tonight into early Thursday morning in the southeastern portion of the CWA, but drier weather will take hold Thursday mid- morning through the rest of the short term period. In terms of temperatures, with the cloud cover to remain through the day, temps most likely will not rise above the mid 30s in most places. Tonight`s lows will be cooler than last with the passage of this latest system. However, with clouds clearing later on tonight as a surface high pressure builds in, high temperatures will be on the increase for Thursday, ranging from mid to upper 40s. .LONG TERM...(Thursday night through Tuesday) Issued at 515 AM EDT WED MAR 21 2018 The long term forecast discussion will follow shortly.
