...POWERFUL COASTAL STORM CONTINUES TO BRING HEAVY SNOW AND STRONG WINDS WITH VERY COLD WIND CHILL VALUES TO FOLLOW... .Surface low pressure southeast of Cape Cod will track northeast toward the Bay of Fundy this evening, with very heavy snow and increasingly strong winds expected across Maine and New Hampshire to the northwest of the low track. Blizzard conditions are likely along the coastal plain, where the greatest combination of heavy snow and strong winds will line up to produce whiteout conditions at times. As the snow winds down this evening, the winds will continue to blow the snow around through the night. By Friday, much colder air will be pulled into the area with wind chill values as cold or colder than what was experienced last week. ...BLIZZARD WARNING REMAINS IN EFFECT UNTIL 4 AM EST FRIDAY... ...WIND CHILL WATCH IN EFFECT FROM FRIDAY MORNING THROUGH SUNDAY MORNING...

* WHERE...The interior coastal plain of New Hampshire and southwest Maine.

* WHEN...Blizzard conditions through late tonight. Dangerous wind chill values expected Friday through Sunday morning.

* ADDITIONAL DETAILS...Winds gusting as high as 50 mph will cause whiteout conditions in blowing snow. Significant drifting of the snow is likely.
