Complex Storm System Brings Multiple Threats into the Weekend

A complex storm system brings heavy rain and the threat for flooding to parts of the region, a potential for some freezing rain in the higher elevations of northern West Virginia, and even a threat for thunderstorms Saturday night followed by gusty winds into Sunday morning. Read More >

Rain across the south into tonight, spreads north by Saturday.

HERE IS THE LATEST WEATHER SYNOPSIS FOR THE MIDDLE OHIO VALLEY AND CENTRAL APPALACHIANS... Clouds and light rain continue today across eastern Kentucky, southern West Virginia and southwestern Virginia, associated with a series of upper level waves passing across the region. Freezing rain is possible across the higher elevations of the northern West Virginia mountains early today and again late tonight. More heavy rain is expected over the weekend, area wide, as another strong low pressure system moves across. Flooding issues are again likely to develop this weekend. Strong thunderstorms are even possible Saturday night. Strong winds are likely to follow the passage of the cold front Sunday morning, and then last into Sunday night. Despite these strong winds, only seasonably chilly air arrives in the wake of the system, for the beginning of next week.   Read More...

Low End Amount – 9 in 10 Chance (90%) of Higher Snowfall

 

This map depicts a reasonable lower-end snowfall amount for the time period shown on the graphic, based on many computer model simulations of possible snowfall totals. This lower amount is an unlikely scenario with a 9 in 10, or 90% chance that more snow will fall, and only a 1 in 10, or 10% chance that less snow will fall. This number can help serve as a lower-end scenario for planning purposes.

Expected Snowfall - Official NWS Forecast

 

This map is the official NWS snowfall forecast in inches during the time period shown on the graphic. This snowfall amount is determined by NWS forecasters to be the most likely outcome based on evaluation of data from computer models, satellite, radar, and other observations.

High End Amount – Only a 1 in 10 Chance (10%) of Higher Snowfall

 

This map depicts a reasonable upper-end snowfall amount for the time period shown on the graphic, based on many computer model simulations of possible snowfall totals. This higher amount is an unlikely scenario, with only a 1 in 10, or 10% chance that more snow will fall, and a 9 in 10, or 90% chance that less snow will fall. This number can help serve as an upper-end scenario for planning purposes.

 
The purpose of these experimental probabilistic snowfall products is to provide customers and partners a range of snowfall possibilities, in complement to existing NWS deterministic snowfall graphics, to better communicate forecast uncertainties during winter weather events.

Percent Chance That Snow Amounts Will Be Greater Than

 

This series of maps shows the probability (that is, the likelihood) that snowfall will equal or exceed specific amounts during the time period shown on the graphic. These forecasts are based on many computer model simulations of possible snowfall totals.

These tables show the snowfall forecast for individual locations, and provide the same information as the graphics on this web page, just shown in a different way. All of these values are valid for the same time period as depicted on the graphics.

Precipitation Onset

Most likely time of winter precipitation onset (snow, sleet, freezing rain). Rain is not included here. This information is provided when we issue a Warning or Advisory for expected snow or ice accumulation; typically six to 24 hours in advance. Times are only given for places that are under a Warning or Advisory. They will be blank in areas outside Warnings or Advisories.

Precipitation End Time

Most likely time of winter precipitation ending (snow, sleet, freezing rain). Rain is not included here. This information is provided when we issue a Warning or Advisory for expected snow or ice accumulation; typically six to 24 hours in advance. Times are only given for places that are under a Warning or Advisory. They will be blank in areas outside Warnings or Advisories.

Low Tracks Graphic

The graphic depicts the forecast location of significant surface lows impacting the 48 contiguous United States in 12 hour increments out to 72 hours into the future.

The low position and track forecast by NCEP WPC meteorologist is in white. Each low position is accompanied by a lead time (Eastern Time). The circles around each low represents a 75% probability the observed low will be located with the circle. Note: The probability is derived using previous season's verification data. For reference, existing surface lows are depicted with a red marker without yellow circles.

Winter Storm Severity Index

The purpose of the experimental Winter Storm Severity Index (WSSI) is to provide NWS partners and the general public with an indication of the level of winter precipitation (snow and ice) severity and its potential related societal impacts.

Reported

As snow and/or ice reports come into the NWS (you can email reports to rlx.webmaster@noaa.gov or Tweet to @NWSCharlestonWV), we will pass them on here. With the map linked here, and the supporting reports below it, you can keep tabs on how much has fallen.
