Warmer air temperatures near Lake Erie will delay the transition of lake effect precipitation from rain to snow tonight in areas north of Interstate 90 in Ashtabula and Erie Counties. Once rain changes over to snow overnight, snowfall is expected to be in a low ratio form and graupel in nature, which will limit accumulations. Therefore, will reduce the forecast for these areas to a slushy inch overnight and cancel the Winter Weather Advisory for higher snowfall amounts, as they are no longer expected. $$ OHZ013-014-190400- /O.UPG.KCLE.WS.A.0002.211119T0000Z-211119T1700Z/ /O.EXA.KCLE.WW.Y.0014.211119T0000Z-211119T1700Z/ Geauga-Ashtabula Inland- Including the cities of Chardon, South Russell, Bainbridge, Chesterland, Middlefield, Burton, Jefferson, Orwell, Andover, and Roaming Shores 103 PM EST Thu Nov 18 2021 ...WINTER WEATHER ADVISORY IN EFFECT FROM 7 PM THIS EVENING TO NOON EST FRIDAY... * WHAT...Lake effect snow expected.
