A strong Pacific system is bringing strong winds and elevated to critical fire weather to portions of the Rockies across to the Plains and Upper Midwest. Also, the late season heat wave continues across portions of California into the Southwest. Finally, Tropical Storm Milton is strengthening in the southwest Gulf of Mexico, and it is expected to impact Florida this coming week. Read More >

Low End Amount – 9 in 10 Chance (90%) of Higher SnowfallThis 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 ForecastThis 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 SnowfallThis 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. |
Percent Chance That Snow Amounts Will Be Greater Than...

Percent Chance That Snow Amounts Will Be Greater ThanThis 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. |
Snowfall Totals by Location

Snowfall Totals by LocationThese 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. |

Ice Accumulation Potential
|
Expected Ice Accumulation - Official NWS Forecast This is the elevated flat surface ice accumulation. It is not radial/line ice. Radial/line ice is typically 39% of the elevated flat surface ice. For more information on this, see this module. |
