Winter Weather Advisory
* WHAT...Mixed precipitation. Additional snow and sleet accumulations up to 3 inches and ice accumulations around one tenth of an inch. * WHERE...Portions of northern Connecticut, central, eastern, and western Massachusetts, and northern Rhode Island. * WHEN...Until 7 AM EST Saturday. * IMPACTS...Plan on slippery road conditions. The hazardous conditions could impact the Friday evening commute.
Special Weather Statement
After a period of light rain/snow showers this afternoon and evening, temperatures will fall below freezing and into the 20s overnight. Light winds will limit how quickly wet surfaces can dry out and thus we expect areas of black ice to develop tonight and persist through the morning commute tomorrow. Travel with caution, especially on untreated surfaces and secondary roads.
Special Weather Statement
Untreated wet ground surfaces from previous rain and melted snow will likely freeze overnight as temperatures drop into the 20s. This will allow for areas of black ice to form on untreated ground surfaces. Motorists and pedestrians should expect areas of icy travel conditions overnight through Thursday morning, especially on untreated ground surfaces and secondary roadways. Elevated roadways such as bridges and overpasses as well as highway on and off ramps will be particularly vulnerable to black ice formation and slippery travel conditions through Thursday morning.
Winter Weather Advisory
* WHAT...Mixed precipitation. Additional snow accumulations up to two inches and ice accumulations around a light glaze. * WHERE...Berkshire County in western Massachusetts and the Mohawk Valley, eastern Catskills, Helderbergs, northern and central Taconics and Capital District in eastern New York. * WHEN...Until 4 AM EST Thursday. * IMPACTS...Plan on slippery road conditions. The hazardous conditions could impact this evening's commute. * ADDITIONAL DETAILS...A mix of snow and rain this afternoon will become all snow this evening and continue into tonight before ending early Thursday morning. Localized pockets of freezing rain will be possible as well, especially along and south of Interstate 90 and in higher elevations, which may produce up to a light glaze. As temperatures fall below freezing tonight, any wet, untreated surfaces may become icy so use caution if traveling tonight.
Air Quality Alert
The New York State Department of Environmental Conservation at Albany has issued a Air Quality Health Advisory for Fine Particulates.. until midnight EST tonight. Air quality levels in outdoor air are predicted to be greater than an air quality index value of 100 for Fine Particulates. The air quality index...or AQI...was created as an easy way to correlate levels of different pollutants to one scale. The higher the AQI value, the greater the health concern. When pollution levels are elevated...the New York State Department of Health recommends that individuals consider limiting strenuous outdoor physical activity to reduce the risk of adverse health effects. People who may be especially sensitive to the effects of elevated levels of pollutants include the very young and those with pre existing respiratory problems such as asthma or heart disease. Those with symptoms should consider consulting their personal physician. For additional information, please visit the New York State Department of Environmental Conservation website at, https://on.ny.gov/nyaqi, or call the Air Quality Hotline at 800-535- 1345.
