Snow and Ice Forecasts & Services

Strong to Severe Thunderstorms from the Southern Plains to the Ohio Valley; Heavy Rain and Flooding in the Southern Plains

Severe thunderstorms are expected from central Texas to middle Tennessee and Kentucky this afternoon into tonight. Large hail and damaging winds are the main threats. Heavy to excessive rainfall may produce areas of flooding today and tonight from central Texas into the lower Mississippi Valley.

Expected Snowfall - Official 博体育 Forecast What's this?	High End Amount 1 in 10 Chance (10%) of Higher Snowfall What's this?
	Low End Amount 9 in 10 Chance (90%) of Higher Snowfall What's this?
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 博体育 Forecast This map is the official 博体育 snowfall forecast in inches during the time period shown on the graphic. This snowfall amount is determined by 博体育 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 博体育 deterministic snowfall graphics, to better communicate forecast uncertainties during winter weather events.

Other Snow/Ice Information

Reported Snow and Ice As snow and/or ice reports come into the 博体育 we consolidate and post them here. You can email reports to lwx-report@noaa.gov or X to @博体育_BaltWash. With the map linked here, and the supporting reports listed below it, you can keep tabs on how much has fallen. Note you can toggle between mapping snow and ice reports using the drop down menu just above the map. Winter Storm Severity Index The purpose of the Winter Storm Severity Index (WSSI) is to provide 博体育 partners and the general public with an indication of the level of winter precipitation (snow and ice) severity and its potential related societal impacts.

What's this?	What's this?
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 that the accumulating winter precipitation ends (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 of the onset. Times are only given for places that are under a Warning or Advisory. They will be blank in areas outside Warnings or Advisories.
