Good Morning, We are monitoring two weather systems through the weekend for possible hazardous weather: *This Afternoon and Tonight:* A strong cold front will cross the region this afternoon, followed by strong west winds this afternoon and tonight, which will mainly affect the marine community. *Marine Impacts: Gale Force Winds* *Locations*: Massachusetts and Rhode Island coastal waters *Timing:* Onset of Gales between 3 and 6 PM, ending between 3 and 6 AM Saturday, except by 11 AM farther offshore. *Wind Gusts:* W 35 to 40 knots, peaking between 8 PM and 2 AM. *Seas:* 4 to 7 feet on the inner bays and sounds; 10 to 15 ft offshore. *Impact:* Hazardous conditions for mariners. *Uncertainty:* Low. *Saturday Night and Sunday:* Low pressure is expected to track near Nantucket. As rain overspreads the region Saturday night, it will be cold enough for a wintry mix across parts of the interior with the potential for light icing and impacts to travel. Milder air will cause a change to rain Sunday morning. *Interior Light Icing (See Attached Image):* *Locations*: Western and north-central Massachusetts, possibly northwest Hartford County, CT, especially in the higher elevations. *Timing:* Wintry mix of snow and light freezing rain late Saturday night into early Sunday morning, changing to rain by late morning or early afternoon. *Impact*: Slippery travel. *Uncertainty:* Timing of the exact changeover. Higher confidence that snow and ice amounts will be light, with up to an inch of snow and a light coating (up to 1/10") of ice. *Minor Coastal Flooding: Sunday Morning High Tide* *Locations*: Eastern Massachusetts coast (including Martha's Vineyard and Nantucket) and the South Coast *Timing:* Sunday morning high tide (5:41 AM at Providence, 8:45 AM at Boston, and 9:46 AM on Nantucket) *Storm Surge:* 1.0 to 1.5 feet *Inundation:* Less than 1 foot above ground level *Impact*: Some vulnerable shoreline roads may become temporarily impassable around high tide. *Uncertainty:* High. Timing of highest surge may not coincide with high tide, which would lead to little or no impact. Minor coastal flooding would be the worst case scenario. *Minor Coastal Flooding: Sunday Evening High Tide* *Locations*: Eastern Massachusetts coast including Martha's Vineyard and Nantucket *Timing:* Sunday evening high tide (9:17 PM at Boston and 10:24 PM on Nantucket) *Storm Surge:* Around 2.0 feet *Inundation:* Up to 1 foot above ground level *Impact*: Some vulnerable shoreline roads may become temporarily impassable around high tide. *Uncertainty:* Lower than with the morning high tide. Locations along the Bay side of Cape Cod, Plymouth County, and Nantucket are most vulnerable. Updates will be sent as needed.
