Londonderry Schools Closed Tuesday January 18th

No snow falling in Ltown when Londonderry called off School at 4:44am.  Our radar showed snow in Massachusetts moving North toward New Hampshire.  The Snow/Ice/Rain line was stretched along Long Island Sound and moving North at 5am.

Snow Day! No school activities through the evening in Londonderry

Both the Town Hall and District office are open.

Trash is not delayed at this time, we will report from the Town Manager when available.

If you have relatives or friends in other parts of the country be sure to have them view our Londonderry webcam as the snow comes down and the ice coats our windows.  Remember the 10/10 rule for your generator! 10 feet away from the house and 10 feet away from the fuel.  Expect local outage reports from readers, if they occur.

Our friend Kevin at WMUR  is showing us in the 3-6 inch range with that nasty coating of ice at the end of the storm. His update at 4:30am “Snow moving in early this AM from south to north with a wintry mix gradually “mixing in” through the aft’n. -Kevin”  Looks like the first flakes will arrive around 7am here in Londonderry

No Change to the National Weather Service Forecast over  night.

Winter storm warning in effect from 7 am Tuesday to 5 am est Wednesday

The National Weather Service in Gray has issued a winter storm warning for mixed precipitation which is in effect from 7 am Tuesday to 5 am est Wednesday. the winter storm watch is no longer in effect. Storm duration and accumulation forecast has increased since Monday afternoon.

  • Timing: Snow will enter the region Tuesday morning between 7am and 10am in Londonderry followed by mixed snow sleet and freezing rain away from the coast Tuesday night. The precipitation will wind down Wednesday morning.
  • Accumulations: 4 to 8 inches or more of snow with one quarter inch of ice.
  • Impacts: Travel will be treacherous. Scattered power outages are possible.
  • Forecast confidence: Forecast confidence in snow amounts is moderate to high however, there is still some uncertainty in the track of the low.  A slightly further east low track will mean lesser snow amounts especially in the northern New Hampshire and western
    Maine mountains. A track further west would yield more snow for the mountains but more of a mix on the coastal plain and perhaps a bit more freezing rain than forecast.
  • Instructions: A mixture of snow sleet and freezing rain will make for difficult travel across the region Tuesday into Wednesday.

Who cancels School in Londonderry

Seeing a lot of searches on the eve of this snowstorm for just that question! In Londonderry the School district and the town are two separate forms of government so don’t look to the town to decide.

The superintendent with the assistance of other individuals including a contracted weather advisory service will make the decision.  Typically around 4am, once that is made the district contacts the media by landlines and lets  them know about schools being closed.

We then broadcast the closing on twitter, Follow Us! At the same time the closing will also be in our breaking news.

While the National Weather Service expects the storm to start at 4am tomorrow morning, the snowfall rate is expected to be 1-2 inches per hour in some locations with gusts to 30mph.  This is expected between the hours of 6am and 2pm Wednesday in the Londonderry area.

Low pressure will track up the east coast and pass Cape Cod on Wednesday. As it tracks just offshore expect snow to fall across much of New Hampshire and Western Maine. the greatest accumulations will likely be along the coast of Maine and Southern New Hampshire. The heaviest snow will fall around daybreak on Wednesday with snowfall rates of 1 to 2 inches per hour. Snow should come to an end by Wednesday afternoon and evening.

Londonderry High School Closed Monday

At this time only the high school is closed all other Londonderry Schools will be open.

The Londonderry Shelter in the High School Gym is open and remain open through the night.

A power line break between the street and the school has forced the district to close the High School Monday.   This is an underground short in the cables that feed the school between Phase 1 and Phase 3.  It will require that the ground be excavated to locate and repair the problem with the cable.

Parents and guardians should also monitor Londonderry Hometown Online News, or another media outlet that provides school closing information in the morning.  If appropriate at that time other school closings may occur due to weather issues developing in the Atlantic off the coast at this time.

This is going to be a multipurpose story

NWS forecast

Winter Weather Advisory for Londonderry and the Region

A strong Atlantic storm will bring snow to Maine and New Hampshire a storm over the Atlantic will strengthen this evening and back westward into the gulf of Maine as it does so moist air wrapping around the system will wrap all the way around and bring precipitation to coastal and interior Maine and New Hampshire.

The heaviest snow will begin this evening along the mid coast of Maine and spread westward across the remainder of the area through the night. as warm air wraps around the storm a change over to rain may occur at the tail end of the precipitation. This could limit total snowfall accumulations in some areas but most of the significant precipitation will fall before the warm air is able to change the precipitation to rain.  In addition temperatures will be very close to freezing and snow will be heavy and wet.  This could make it hard to accumulate to road surfaces initially but as snow becomes heavy even road surfaces will become snow covered. Since most of the snow will fall during the night time hours accumulations could occur more quickly. Most of the precipitation will end across New Hampshire and western Maine by tomorrow Morning

As the sun comes up in the morning temperatures will warm in lower elevations and may help change precipitation to rain before ending. Total snowfall accumulations of 3 to 6 inches are possible through Monday morning. In addition to the snowfall…strong northerly winds will accompany the storm. Wind gusts to 35 mph will be possible especially in exposed areas and in the higher terrain. A winter weather advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities and use caution while driving.
