I’m a third-year atmospheric science student at Cornell University who has been blogging about the weather since 2011. While I’m not officially a meteorologist, I have accumulated a bit of experience forecasting both local weather (in western Maine and New Hampshire) as well as national/international weather during my time writing for weather.us and weathermodels.com. I also have experience programming in Python, teaching concepts in weather forecasting, and communicating forecast information to general audiences.

Cooling Temps Today

Hello everyone!

A cold front passed offshore very early this morning, and temps have been falling ever since. That cooling trend will continue through the day today, with morning temps near freezing in the north and around 40 in the south giving way to afternoon temps around 15 in the north and dipping below freezing in the south. Those colder temps will be moving in on NW winds, so expect an upslope/downslope pattern to develop today with more clouds than sun in the mountains and more sun than clouds along the coast. Additionally, snow showers and flurries will continue in upslope flow over the higher terrain, with dry conditions expected in downsloping areas.

Mild With Areas Of Rain And Fog Today

Hello everyone!

Today will feature mild temperatures, spotty precipitation, and more widespread fog as warm moist air moves north over our cold snowpack. Look for highs to rise to freezing in the north and 40 in the south. More significantly, dew points will rise above freezing for the whole area today. As this moisture moves over our recently replenished snowpack, it will condense into areas of fog that could be dense at times. Precipitation will be most persistent in northern areas, closer to the front that passed through last night. Most of the precipitation falling along this front will be in the form of rain for the lower elevations, with snow limited to the higher terrain of the White Mountains.

More coastal rain arrives tomorrow, but as cold air invades the low levels inland, look for a change to freezing rain as the next round of precip arrives.

Increasing Clouds Today

Hello everyone!

Today will feature increasing clouds as our next round of snow approaches from the west. We’ll see mostly sunny skies to start the morning, but by lunchtime we’ll rapidly be moving towards overcast. Highs today will range from 10 in the north to 25 along the coast. Snow will begin late in the evening over New Hampshire, reaching Maine shortly before midnight. Snow will continue through the early morning hours tomorrow, accumulating 1-3″ in Southern New Hampshire, 2-4″ in the foothills of NH and the coastal plain of ME, and 3-6″ in the mountains.

Cooling Temps And Clearing Skies Today

Hello everyone!

Yesterday afternoon’s snowfall is long gone this morning, and it will be replaced by both cooler and clearer weather today. Temps will top out around 10 in the mountains and around 20 along the coast as NW winds carry colder air into the region. Those NW winds also mean we’ll see a familiar pattern with regards to precipitation chances and sky cover as the mountains see snow showers and flurries continue in upslope flow, while the coast sees mostly sunny skies and dry conditions in downslope flow.

Very Heavy Snow This Afternoon

Hello everyone!

Our weather today will be split into two parts as dry conditions hold through the morning, and very heavy snow arrives this afternoon. Expect snow to develop from west to east around midday. Snow will be falling across NH by 11 AM and across ME by noon. It will become heavy not long after the first flakes fly, with snowfall rates reaching 2-3″ per hour by the 2-3 PM timeframe. The heavy snow will continue through the evening before tapering off from W to E between 9 and 10 PM. Precipitation types should remain all snow for most of the area, the exception being the NH seacoast, the coastline S of Portland, and the Midcoast peninsulas east of Brunswick. In these areas, look for a change to sleet/freezing rain/rain late in the afternoon as warm air attempts to surge north. 8-14″ of snow is expected for the all snow areas, with 4-8″ in the aforementioned coastal areas that will see mixing. High temps will range from 20 in the north to 35 along the parts of the coastline mentioned above.

Cool With More Clouds Today

Hello everyone!

Today’s weather will be mostly under the control of a weak upper level disturbance cruising through the area from west to east. This system will bring mostly cloudy skies to the entire area, and some snow showers are also expected for some parts of the area as it moves through. The best chance for some light snow will be in the foothills and mountains, though even the coast could see flurries. Accumulations, if they do occur, will remain less than an inch. Highs will range from the upper 10’s north to the upper 20’s south.

A much more significant snowstorm is on the way for tomorrow afternoon/evening with 8-12″ expected for the majority of the area.

Another Breezy Day Of Falling Temps Today

Hello everyone!

Today will feature breezy conditions and falling temps as cold air moves in behind a front that passed through the region last night. Look for current temps in the 30’s to give way to 10’s by sunset. This cooling will be powered by NW winds which will gust over 30 mph at times, making the already-cool temps feel much colder by this evening. Skies will start the morning cloudy, but clearing is expected this afternoon southeast of the mountains as downsloping kicks in. In the mountains, upsloping will keep clouds and snow showers in the mix through the evening hours.

Snow Changing To Rain Outside Of The Mountains Today

Hello everyone!

Today will feature snow changing to rain for areas outside of the mountains as warm air surges in from the south. Temps this morning are cold enough for flurries all the way to the coast, but expect temps outside of the mountains to quickly warm above freezing before the main round of precipitation arrives this afternoon. Once that precipitation arrives, we’ll be dealing with a tale of two storm systems across the area. In the mountains, moderate to heavy bands of snowfall will cause slick roads and low visibility. Along the coastline, southerly/southeasterly winds will gust over 40 mph as heavy rain bands rotate through. Impacts from both are expected to be moderate as snow in the mountains will be enough to cause some travel problems, but not enough for any major issues, and winds along the coast will be enough for some scattered power outages, but not enough for any widespread damage.

High temps today will range from 30 in the northern mountains to 40 along the midcoast. Rain and snow will exit the region early tomorrow morning.

Morning Snow Gives Way To A Cool And Breezy Afternoon

Hello everyone!

Today will feature rapidly dropping temps as a cold front has now moved offshore. Radar shows light to moderate snow ongoing for most of the area as of 4:45 AM. Some areas along the immediate coast are still warm enough to be seeing rain, but with the incoming cold air, expect any leftover raindrops to change over to snow in the next hour or so. Light to moderate snow will continue for the next few hours as a wave of low pressure develops in the Gulf of Maine. As this wave races off into the Canadian Maritimes, expect snow to taper off from west to east once we get towards the middle part of the morning. Temps will follow a non-diurnal curve today, meaning that they will continuously fall instead of rising once the sun comes up. Current temps range from the mid 20’s in the north to the mid 30’s near Rockland. By 6 PM this evening, temps will range from 0 in the mountains to 10 along the coast. Those temps will feel even colder once you factor in NW winds gusting 20-30 mph. Bundle up if you’re headed out!

Light Snow Today

Hello everyone!

Today will feature light to occasionally moderate snow as a weak warm front aloft drifts through. Radar imagery shows snow currently falling across parts of the Midcoast as well as York County and the Southern third or so of New Hampshire as of 4:45 AM. This band of snow will lift north today, bringing accumulations of 1-3″ for most, with a few 4 or maybe even 5″ totals just inland from the coast. Steady snow will move out early in the afternoon, with just scattered snow showers left over in the mountains. Temps will slowly be warming today as we get winds from the southwest. Look for highs ranging from the upper 20’s in the mountains to the mid 30’s along the NH Seacoast.
