All eyes are on the approaching Winter Storm, which is already bringing a cold rain to much of our region this morning. The National Weather Service has issued a Winter Storm Warning for our viewing area, which is indicated by the pink shading below...
This is in effect from 7 PM this evening through 7 PM Monday for the threat of freezing rain, sleet, and snow.
Temperatures will begin to drop below freezing to our northern extents around 1 PM, and we will see a progression of cooling temperatures from the north to the south for this afternoon. Here is the NAM outlook, showing the progression of the event...
According to the NAM, by 1 PM, Southern Ohio will start to see freezing rain, while the rest of the region will be affected by a heavy rain. By 7PM, areas along the Ohio River in West Virginia, including Huntington, will start to freezing rain. The line of freezing rain will progress further southward through the evening, until a transition to snow occurs around dawn region wide.
This is the GFS outlook...
The GFS expects the transition to freezing to occur earlier, with the River Cities seeing freezing rain before 4 PM (around 2PM). Furthermore, the transition to snow occurs earlier, with snow pushing into areas like Huntington around 2 AM. The GFS also expects region wide snowfall through the 7 AM hour.
The big question with this storm is the amount of ice and snow expected. The issue is that it is hard to determine how much of the available moisture will fall as a particular precipitation type, especially with some uncertainty about the exact timing of the transitions. In general, 0.25-0.5" of ice is expected and a general 4-8" of sleet/snowfall.
Stay warm and continue to stay updated by watching WSAZ.
Enjoy the rest of your weekend,
