Severe Thunderstorms and Heavy Rainfall for the Southwest; Heat Spreads Across the Center of the Nation

Moisture will continue to move into areas of the West. This will increase showers and thunderstorms coverage and intensity, with the risk of flash flooding and damaging wind gusts. Meanwhile, heat across the Southwest will expand into the center of the nation this weekend into early next week. Trends favor this heat will spread across the Ohio Valley, mid-Atlantic next week.

Low End Amount – 9 in 10 Chance (90%) of Higher Snowfall over 72 hours

 

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.

"Point Map" is Expected Snowfall - 72hr Official NWS Forecast

 

The "Point" map is the official 72 hour 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.

"Range Map" is Experimental Probabilistic Snowfall Range Amounts over 72 hours

The "Range" map is the 25th percentile (lower number) to 75th percentile (higher number) of possible snowfall amounts based on the Weather Prediction Center (WPC) Super Ensemble output during the time period of the graphic. The official NWS snowfall forecast influences this range of values either up or down depending upon how closely they match.

High End Amount – Only a 1 in 10 Chance (10%) of Higher Snowfall over 72 hours

 

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 72 Hour 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.
