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.

Heavy Snow Gradually Winds Down Today

Hello everyone!

Bands of heavy snow are rotating onshore this morning as a Nor’easter moves through the Gulf of Maine. Many places have already picked up 6-12″ with another 4-8″ yet to come depending on the exact location. Snow will continue through the morning before slowly tapering off from south to north this afternoon. Expect the first signs of slowing over Southern NH a little before noon, with snow continuing in the mountains all the way into the wee hours of tomorrow morning. Temps today will range from a little above 20 in the north to a little above 30 in the south. NE winds this morning will turn to the north and eventually northwest this afternoon, and will remain breezy though not quite strong enough to cause major issues. However, the combination of heavy wet snow and breezy winds will result in the threat of power outages along the coast where many are already in the dark.

Major Snowstorm Arrives This Evening

Hello everyone!

Today will feature a generally quiet morning as the calm before a major snowstorm continues. Winds out of the northeast will gradually pick up today with gusty conditions arriving by evening. Satellite imagery shows overcast skies already in place across the area, something that won’t change through the day as moisture flows into the region from the southeast. Upslope and ocean effect flurries have been reported this morning, and these will remain the only sources of precipitation through around noon when snow from the main storm system will begin to overspread the area from SW to NE. Look for temps to warm up a little bit as the sun comes up today before falling this afternoon/evening as precipitation arrives. Highs will range from 30 in the mountains to 40 along the NH Seacoast.

The storm itself will crank into high gear tonight with bands of extremely heavy snow moving in from the ocean. Snowfall rates will exceed 2″ per hour in many locations with near zero visibility in heavy falling and blowing snow. Snow will be heavy and wet along the coast where temps will be closer to freezing, while the mountains see fluffier accumulations. Storm totals will range from 8-12″ along the immediate coastline to 12-24″ for most of the rest of the area. Amounts over 2 feet are expected in favored higher terrain upslope areas. Snow will gradually let up from south to north tomorrow during the morning except for the mountains where snow will continue right through the weekend as another ocean storm backs in from Nova Scotia. As northeast winds gust over 40 mph and trees become laden with heavy snow, expect power outages along the coastline tonight.

The Calm Before The Storm Today

Hello everyone!

Today will feature the calm before our next storm system blasts into the area tomorrow night with heavy snow and strong NE winds. Look for temps a few degrees colder today compared to recent days as cooler air filters into the region ahead of the storm with highs ranging from around 30 in the mountains to around 35 along the coast. Persistent cloud cover is visible on satellite imagery for much of Maine and Eastern NH, with sunshine across western NH. This general pattern is expected to continue through the day today as low level moisture remains close by due to the offshore storm still lingering from Friday. No precipitation is expected until tomorrow as our storm moves in.

More Of The Same Weather Today

Hello everyone!

Today will feature another day of the weather we’ve been dealing with since Friday. Temps will warm into the 30’s across the region, cloud cover will be widespread, though not everyone will remain entirely overcast through the whole day, and winds will remain gusty from the NNE. A backdoor cold front moved through the region last night, with a little snow falling as forecast. Behind that system, cooler air will pour into the region today, though we won’t really feel a noticeable change in temps until Wednesday, when the cold dry airmass becomes filled with snowflakes. No major precipitation is expected today, though snow showers are likely to continue in the mountains with some locations picking up another coating-1″ of snow.

Our next storm looks to be a fairly sizeable one, and will arrive Wednesday evening with high winds and heavy snow.

Another Cool And Breezy Day Today

Hello everyone!

Today will feature another day under the influence of the major storm that brought wind, rain, snow, and coastal flooding on Friday. That system is drifting ever so slowly southeast across the Atlantic, but its large size means that northerly breezes will be felt once again today along with areas of cloudiness, especially in northern and eastern parts of the region. A backdoor cold front will move through the area this evening with overcast skies and a burst of snow for southern areas. Accumulations will remain confined to a coating for most areas south and west of PWM, but a few locations along the MA/NH border could see an inch. Snow will move in late this evening and out just after midnight. Temps will range through the 30’s today with the coldest temps below freezing in the mountains, and the warmest just shy of 40 along the coast.

Breezy And Cool Today

Hello everyone!

Today will feature breezy and cool weather as yesterday’s storm moves to the southeast. Winds out of the north will continue to gust in the 30-40 mph range, which could result in scattered power outages, but should be low enough to avoid major issues. Temps will hold steady through the day as daytime heating from the sun is balanced by cold air advection behind the storm. Your temperature this morning will be your temperature at noon will be your temperature this evening (plus or minus a few degrees), before the sun goes down and cooling begins. While only scattered rain/snow is expected from the storm today, its impacts will continue with another round of impactful coastal flooding expected around the midday high tide.

Mild Weather Continues Today

Hello everyone!

Today will once again feature very warm temps as storms track along a front to our north. Look for highs ranging from the upper 30’s in the north to the low 50’s along the southern coast. Skies will feature a mix of sun and clouds, with more sun in the south and more clouds in the north. Look for conditions to remain mostly dry outside of a few morning showers in the north and east, and a few upslope showers this afternoon.

We’ll be on the edge of a major coastal storm tomorrow. For my discussion of that storm, check out last night’s weather.us blog update.

Another Very Mild Day Today

Hello everyone!

Today will feature weather that would be lovely in April. A series of storm systems are tracking to our north along a stalled frontal boundary, and by virtue of being to their south, we’re on their warm side. The result will be another day of very mild weather. Look for highs ranging from around 40 in the north to a little above 50 in the south. Skies will feature a mix of sun and clouds, with more clouds expected closer to the storm systems in the north, and more sun expected in the southern parts of the region. Areas outside of the northern mountains will stay mostly dry today, with some rain and snow showers expected in the northern mountains. Precipitation type will be elevation-dependent with these showers, with rain in the valleys, and several inches of accumulation on the summits.

Mild And Calm Today

Hello everyone!

Today will feature mild temperatures and quiet weather as high pressure builds across the area from the west. Look for high temps to soar into the 40’s for all but the mountains, where mid to upper 30’s are forecast. Satellite imagery shows clear skies across the area this morning, a trend that is expected to continue until this evening when a few high clouds will drift into the area in advance of a storm system that will end up moving to our north tomorrow.

Mild And Clear Today

Hello everyone!

Today will feature mild temps and clear skies as drier, but not colder, air moves into the region from the west. Expect temps to rise into the upper 30’s north and mid 40’s south with morning fog burning off to afternoon sunshine downwind of the mountains. Scattered upslope cloudiness is expected in the higher terrain. No precipitation is expected outside of localized upslope flurries as light westerly breezes bring drier air into the region. Enjoy the beautiful day!
