Weather center - The Past Week's Observations at Silver Spring, MD
TEMPERATURE (REAL & APPARENT)
The temperatures for the last 7 days. Also included are two measures of apparent temperature -- how hot or cold does it feel outside? The Wind Chill is a combination of the temperature and wind speed and gives an idea of how horrific it feels out during the winter. The Heat Index is a combination of the heat and humidty and gives an idea of how muggy it is during the summer.
RAINFALL
The past 7 days of rainfall are given below. Also included is the Rain Rate, which is a measure of how hard it was raining, if it is.
WIND AND PRESSURE
Below are the 7-day observations of the wind speed here. The wind direction is also given, which is useful for finding the prevailing wind direction - a good indicator of the sort of air mass we're in or are getting. Also the barometric pressure history is shown. Falling pressure generally indicates a change to stormy weather, while a rising barometer generally indicates improving weather.
SOLAR ACTIVITIES
We're able to provide several statistics on the amount of solar radiation and ultraviolet light reaching our location. Of particular note is the UV Index. Exposure to UV light causes tanning of the skin, excessive exposure is believe to cause premature aging and skin cancer. Or, at the very least, an uncomfortable sunburn.
OTHER WEATHER VARIABLES
Other variables that are important to the overall weather picture, but don't fit into the categories above.
SOIL CONDITIONS
