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.

Coastal Snow This Morning, Clearing This Afternoon

Hello everyone!

Snow is ongoing along the immediate coastline this morning, generally east of the Turnpike as expected. Look for flakes to continue to fly in these areas through the early afternoon hours, but as temps slowly rise into the mid 30’s outside of the mountains, don’t expect much in the way of accumulations. Most treated roads should remain wet, though as always watch for a few slick spots here and there. Snow departs this afternoon as a disorganized storm system lumbers eastward towards Nova Scotia. As that system moves out, look for some clearing to develop, especially across NH where NNW winds will feature more of a downsloping component than areas farther east.

Cool And Cloudy Today As Storm System Moves By To Our South

Hello everyone!

We’re sitting on the far northern fringe of a developing Nor’easter this morning, and we’ll stay on the fringe of this system through the day tomorrow. The result will be cold and cloudy weather, as cold/dry air flows south out of Canada towards the storm. Highs today will sit within a few degrees of freezing across the area, and NNE breezes will pick up enough to things feel noticeably chilly. Overcast skies will further enhance the cold feeling today, though any snow from the storm will wait to move into extreme southeast parts of NH until this evening. Snow will try to nose farther northwest tonight as the storm develops, but given the very dry airmass in place in the low levels, I’m skeptical that it will make much if any progress in that direction. Due to the dry air, accumulations will be limited to areas east of the Turnpike, where 1-3″ is expected. The only exception to this map be areas near Rockland and far SE NH where 4 or 5″ could fall depending on if any heavier banding can drift onshore.

Remaining Cool Today With Increasing Clouds

Hello everyone!

Today will feature another cool day across the region as high pressure anchored in Canada has control of our weather. Look for highs ranging from the mid 20’s up north to the mid 30’s along the southern coastline. Skies will begin the day mostly sunny, but by the afternoon and evening hours, clouds will begin to increase as a storm system begins to organize off the Mid Atlantic coastline. This storm will intensify offshore tomorrow, and brush our area with some light snow tomorrow night into Thursday morning.

Feeling Like January Today

Hello everyone!

Today’s weather will come straight from January’s playbook as our weather pattern is driven by the Arctic cold front that passed through this weekend. Look for cold temps not getting above 20 in the north and 30 in the south, along with gusty NW winds to make things feel even colder than they actually are. Those NW winds will drive a classic upslope/downslope pattern for sky cover/precip chances today, with partly to mostly cloudy skies and occasional flurries in the mountains, and mostly sunny skies in the south along with dry conditions.

Arctic Cold Front Arrives Today

Hello everyone!

We’re now moving into the second half of March, and after a parade of three major Nor’easters, it’s time for another throwback to the deep winter months today in the form of an Arctic cold front. The front is pushing south this morning, and by noon just about everyone will be enjoying cooling temps and gusty NW winds. As the front pushes south, some snow showers ongoing in the mountains will make a run for the coastline. Any accumulations will remain under the 1″ mark, but visibilities will be quickly and drastically reduced in areas of locally heavy snow. Once the front passes and NW winds take over, we’ll see our classic upslope/downslope setup lock into place with clouds and snow showers up in the mountains, and mainly sunny skies along the coastline. Temps will fall today, from the lower 20’s this morning to the 10’s this evening.

Snow Tapers Off Today

Hello everyone!

Heavy snow continued overnight across the area as our storm pivots around the area to the east. Radar shows bands of moderate to heavy snow continuing into this morning in certain spots, mainly the northeastern half of the region closest to the storm itself. Snow will slowly taper off from south to north today, with flakes continuing to fall in the mountains all the way through tomorrow. Additional accumulations will range from a coating-2″ southwest of Portland to 4-8″ in the mountains.

Even as steady snow tapers off today, watch for the development of locally strong snow squalls that will produce brief but intense bursts of heavy snow, gusty winds, and reduced visibility.  Winds will be gusty today in southern areas, especially for areas near the shoreline. This will result in some areas of blowing snow, even after the flakes stop flying. Calmer conditions are expected closer to the enter of the low up in the mountains.

Temps today will range from a few degrees below freezing in the north to a few degrees above in the south.

Major Winter Storm Today

Hello everyone!

Today will feature yet another major winter storm as our very active weather pattern rolls along. Radar imagery shows bands of heavy snow just starting to move onshore this morning. These bands will continue to expand north and west through the morning and into the afternoon as strong low pressure moves southeast of Cape Cod. Snow will fall at rates of 1-3″ per hour at times, covering roads and reducing visibility. As the storm strengthens offshore, winds will increase as well, with gusts over 40 mph expected along the coast. This combination of wind and heavy snow will bring blizzard conditions, and blizzard warnings are posted for the coastline. Temps today will range from the mid 20’s north to the low 30’s along the coast. Total snowfall accumulations will fall between 1 and 2 feet for most towns.

The Calm Before Another Storm Today

Hello everyone!

Today will feature the calm before yet another storm, currently gathering strength over the Carolinas. That system will bring heavy snow and gusty winds to the area tomorrow, with accumulations over a foot expected for most areas. Today, we’ll see morning sunshine give way to afternoon clouds, with some ocean effect flurries even possible near the shorelines south of Portland. Highs will range from 30 in the north to just shy of 40 in the south. The bulk of the snow will hold off until tomorrow morning.

Another Cool And Unsettled Day Today

Hello everyone!

Today will feature another day of generally cool and unsettled weather as low pressure remains stoutly positioned to our northeast. This will keep winds generally out of the northwest today, and as a result we’ll see our familiar upslope/downslope pattern emerge. Look for more clouds than sun in the mountains today with highs in the upper 20’s and occasional snow showers. Along the coastal plain, look for highs in the upper 30’s with a mix of sun and clouds and generally dry conditions.

Continued Unsettled Weather Today

Hello everyone!

Today will feature continued unsettled weather as another storm system develops over Nova Scotia and backs into Northern Maine from the east. While this storm will not be a direct hit for us, it will bring clouds and some snow showers, both of which are more likely the farther northeast you go towards Augusta. You can see the system spinning to the northeast and pushing clouds/snow showers into the area on visible satellite loops. Highs today will range from around 25 in the mountains to around 35 in southern areas that see some sunny breaks. Additional snowfall accumulations today will be limited to areas in and northwest of the mountains, where a general 1-3″ will fall. Some higher elevation spots will see slightly higher totals in the 2-4″ range.
