Lewiston, ID – The National Weather Service (NWS) has issued a warning for locally heavy rainfall expected on Wednesday afternoon and evening throughout the Inland Northwest. Residents in southeast Washington and the lower Idaho Panhandle should prepare for scattered showers and isolated thunderstorms that could bring significant rainfall rates.
Forecasters highlight that the most intense storms could produce rain at rates ranging between half an inch to one inch per hour. While there is some uncertainty about the precise locations of the heaviest rainfall, areas within the 5% (green-shaded) and 15% (yellow-shaded) probability zones on the forecast map are at the greatest risk.
Details on the Expected Weather Conditions
The National Weather Service indicates that scattered showers and isolated thunderstorms will dominate the weather scene on Wednesday across the Inland Northwest. The strongest activity is predicted particularly during the afternoon and evening hours in parts of southeast Washington and the lower Idaho Panhandle.
- Possible rainfall rates from 0.5 to 1 inch per hour.
- Threat of locally heavy rainfall that could lead to temporary flooding in low-lying areas.
- Uncertainty remains regarding the exact locations of the heaviest precipitation.
Understanding the Probability Zones
The forecast map from the NWS features two highlighted regions indicating the probability of the heaviest rainfall:
- Green-shaded area (5% probability): Zones with the highest chance of experiencing concentrated heavy rain.

Forecasters emphasize that while confidence in pinpointing these zones is low, residents within these areas should remain alert and take necessary precautions.
“The confidence in the exact placement of the heaviest showers is low, but those within the designated probability zones should expect the potential for heavy downpours,” said NWS forecasters.
