DISCLAIMER: Data are provided for information only. Accuracy and availability are not guaranteed. Times are local (either EST or EDT). Twice per year, during change-over from and to daylight savings time, the time axis labels will be incorrect. Data is rounded to the nearest integer, except for sea-level pressure and precipitation amounts. Wind chill is calculated from the following formula: WC = 35.74 + 0.6215T - 35.75V 0.16 + 0.4275T V 0.16 where WC is the wind chill index in øF, T is air temperature in øF, and V is wind speed in mph. Wind-chill is not displayed if the air temperature is greater than 40øF, or if the wind speed is less than 4 mph. Dew-point temperature is calculated from the measured temperature and relative humidity. Precipitation amounts may be inaccurate for snow or other frozen precipitation.
