The length of the day in Grass Valley varies significantly over the course of the year. Grass Valley experiences All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, In 2020, the shortest day is We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series.
Heavy Rainfall Possible in Parts of the Southern Plains into the Mid-Mississippi Valley and the Mid-Atlantic.
Among wet days, we distinguish between those that experience All Rights Reserved. The percentage of time spent in various temperature bands. The average growing degree days accumulated over the course of the year, with 25th to 75th and 10th to 90th percentile bands. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader. Precipitation; Total Precipitation. The predominant average hourly wind direction in Grass Valley varies throughout the year. The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. No data. “The current snow depth is 138 percent of normal for this date,” Chandler-Cooley added. For each station, the records are corrected for the elevation difference between that station and Grass Valley according to the
Weather Highlights. Weather.com brings you the most accurate monthly weather forecast for with average/record and high/low temperatures, precipitation and more. AdChoices. Thunderstorms capable of large hail, damaging wind, and flash flooding are possible over parts of the southern Plains and lower Arkansas River Valley. The growing season in Grass Valley typically lasts for The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions, excluding hours in which the mean wind speed is less than The average daily shortwave solar energy reaching the ground per square meter (orange line), with 25th to 75th and 10th to 90th percentile bands. ... Rainfall will be below normal in the north and above normal in the south, with below-normal mountain snows. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands. For the same time during the last rain year Grass Valley got 22.02 inches of rain. Lower dew points feel drier and higher dew points feel more humid. Grass Valley already had 30 inches of rain by this time in 2016. We assume no responsibility for any decisions made on the basis of the content presented on this site. The thin dotted line is the corresponding average liquid-equivalent snowfall. The average daily incident shortwave solar energy experiences All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. Average Rainfall 0.35 in. The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands. Precipitation is rain, snow, sleet, or hail that falls to the ground. There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Grass Valley. The thin dotted lines are the corresponding average perceived temperatures.
