NH1 First Alert Weather: Chilly Gusty Winds Friday, Supermoon Weekend

NH1 Chief Meteorologist

Hello Friday! Today will be all about the gusty NW winds that will move in behind a cold front around mid- morning. Will likely see gusts of 30-35 mph, with some possibility of hitting 40 mph at times. Best chance for the highest gusts will be around midday right as the front pushes off the coast. Gusty winds will continue through the afternoon and will gradually weaken thru the evening. Otherwise, look for some upslope snow showers in the mountains with accumulations of an inch or so on the highest terrain. The upslope clouds will linger in the mountains all day, but the downslope will clear out those areas and make for a partly to mostly sunny skies. The Highs in the upper 40s to near 50 in the south, but they will only peak in the lower 40s in the morning in the mountains and then fall during the afternoon. Winds diminish during the evening with clear skies. Overnight lows will drop into the low to mid 20s in the N and to the upper 20s in the south.

Winds will relax on Saturday as high pressure builds into the Ohio Valley and the Mid Atlantic. It will still be cool with highs in the 40s on Saturday and lows near or below freezing Saturday night. But warmer air begins spilling out of the decaying ridge and spills east into New England, allowing temperatures to rise back into the mid 50s Sunday and Monday with plenty of sunshine. Don't forget the Full Supermoon Sunday night rising at 4:14 PM. It will be the closest Supermoon we have seen since 1948! That is incredible. Look east as it rises over the horizon for the big show!

Heading into next week, there are a few question with how it will play out. A significant surface low with reaches the Southeast coast on Monday, tracking it northward on the east side of the developing trough, up the East Coast and toward New England for Tuesday into Wednesday. Timing exactly when the rain will arrive is subject to change. It does appear likely that there will be a rain event sometime during the midweek period.

Thanks to the full Supermoon, the highest astronomical tides in years are expected Monday-Tuesday and Wednesday. Onshore winds along with a developing low up the coast will likely cause some coastal flooding in vulnerable locations along the coast from Main, NH into MA. Storm Surge flooding is likely with these conditions. We saw the King Tide Flooding which happened this past October. This round could be worse, so it is something to be aware of and prepare for if you are in a flood prone location.
