Storm Coordination Message #2 -Thursday 10/27-Friday 10/28/11 Potential Storm Event
Hello to all..
..Storm System will affect Southern New England Thursday Morning through Friday Morning with a decent rainfall, potential for some snowfall accumulations in Northwest Massachusetts and Southwest New Hampshire and perhaps even some snowflakes seen over much of Southern New England before precipitation ends along with the threat for Minor Coastal Flooding at the Thursday Midday high tide..
..A Coastal Flood Advisory is in effect from 9 AM to 2 PM EDT Thursday for East Coastal Massachusetts including Cape Cod and the Islands..
..Snowfall in Northwest Massachusetts is currently expected to be 1-3″ of heavy and wet snow but will be contingent on the timing of the changeover in precipitation from rain to snow and the amount of precipitation that falls as snow. If amounts reach 2-3″ or higher, isolated pockets of tree and wire damage will be possible. This is particularly true in the higher elevations..
..SKYWARN Activation with Ops at NWS Taunton are possible for the Thursday high tide cycle and then for snowfall late Thursday Afternoon through early Friday Morning..
A storm system will affect the region Thursday Morning into Friday Morning. Precipitation will start as rain and could be heavy at times. About 1 to 1.5″ of rainfall with isolated higher amounts is possible.
As we get into Thursday Evening, possibly as early as the evening rush hour in Southern New Hampshire and Northwest Massachusetts, rain could change to a heavy wet snow. At this time, 1-3″ of snow is expected. With trees having foiliage on them in some areas and the weight of the heavy wet snow, there is potential for isolated pockets of tree and wire damage. This is particularly true in the higher elevations. This potential would rise significantly if more of the precipitation falls as that heavy, wet snow and that will need close monitoring. The current scenario, however, is for 1-3″ of heavy and wet snow. Wet snowflakes may be seen all the way through Southeast Massachusetts and Rhode Island before the rain ends late Thursday Night but this will again depend on how much cold air seeps into the region. No accumulation is expected outside of Southwest New Hampshire and Northwest Massachusetts.
The other potential threat from the storm system is minor coastal flooding at the time of the midday Thursday high tide. A significant storm surge is not expected but with high astronomical tides and the onshore Northeast flow, minor coastal flooding will be possible with the impact to shore roads along the east coast of Massachusetts including Cape Cod and the Islands. A Coastal Flood Advisory is in effect from 9 AM to 2 PM Thursday to cover this potential for minor coastal flooding midday Thursday.
SKYWARN Activation with Ops at NWS Taunton are possible Thursday for the coastal flood potential and rain changing over to snow late Thursday Afternoon through early Friday Morning. Another coordination message will be posted by 9 AM Thursday Morning. Below is the NWS Taunton Coastal Flood Advisory Statement and Hazardous Weather Outlook:
