Is snowfall on Yahoo Weather cumulative?

Yahoo Weather for my town says the following... does this mean 5 to 8 inches in total, or 5 to 8 inches for tomorrow during the day plus an additional 5 to 8 inches falling tomorrow night?

# Tomorrow: Windy. Morning snow showers will evolve into a steady snow, some of it heavy, for the afternoon. High 32F. Winds NNE at 20 to 30 mph. 5 to 8 inches of snow expected. Winds could occasionally gust over 40 mph.

# Tomorrow night: Snow along with gusty winds at times. Low 23F. Winds NNW at 20 to 30 mph. Snow accumulating 5 to 8 inches. Winds could occasionally gust over 40 mph.

    When it is written that way, it means for every forecast periods, you should expect to see 5-8 inches of snow. So the answer to your question is 5 to 8 inches for tomorrow during the day plus an additional 5 to 8 inches falling tomorrow night.

    When they add storm total cumulative amount as part of the text forecast, they will add another line and it will be written in a way that makes it clear that you are looking at at the cumulative starting from the start of the event

    .

    When ever you see just one accumulation listed per forecast period, it is almost always the storm totals accumulation expected for the forecast period.

    Example:

    Tonight...Cold with periods of snow. Low near 27 degrees. Northwest winds 15-25 mph. Snow accumulation of 5 to 8 inches expected. Storm total accumulations 12-18 inches.
