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.

Strong Backdoor Cold Front To End Fall Warmth Today

Hello everyone!

Fall break is now over, and I’m back at home base in Ithaca, meaning that updates will resume as per usual. Likewise, Mother Nature is also set to cease pretending like it’s summer vacation today, with a backdoor cold front bringing an end to unusually warm fall temps. Our airmass this morning is warm and muggy across the area, with dew points in the 60’s more typical of July than October.

By sunset, most of Maine will be dropping through the 50’s into the 40’s as breezy NE winds kick in. However, before that, temps will rise into the low to mid 80’s for most of SW ME and NH. Along the front, showers and storms are possible this afternoon/evening as those warm temps and muggy air will actually lead to some instability. Those showers/storms will wane in intensity after sunset.

Cool And Cloudy Today

Hello everyone!

Today will feature cool temps and cloudy skies as we sit north of a warm frontal boundary. Most of these clouds will be in the low levels, meaning that fog is also a possibility, especially this morning. Precipitation by and large won’t be an issue, though scattered showers are expected as that warm front lifts a little closer. If you’re looking for the best shot at sunshine, head to the midcoast, where you’ll also find the warmest temps around 55. The rest of the area will range between 45 in the mountains and 50 elsewhere in terms of temps.

Special Update: Tomorrow’s Forecast A Little Early Plus Pictures From A White Mountain Sunrise

Hello everyone!

You may have noticed I wasn’t able to get an update out this morning. My apologies for that! I was up in the White Mountains taking in a stunning sunrise as part of resting and recuperating during fall break. I have similar, though slightly less spectacular, plans for tomorrow morning, so I’ll post the forecast now to keep everyone up to date. As a side note, if you’re interested in seeing pictures from the hike, scroll down!

Tomorrow, Sunday, will feature plenty of clouds and temps split dramatically between north and south. Both of these are due to the fact that a frontal boundary will be sitting overhead for most of the day. The front won’t be strong enough to get much in the way of precipitation going, but it will be strong enough to keep cloud cover fairly dense for most of the area. Cool air north of the front will limit highs in the mountains to around 50, while warm air south of the front will let temps climb above 70 in southern NH. The best chance for showers will be in the mountains.

Cool And Dry Today

Hello everyone!

Canadian high pressure is building into the area this morning with cool and dry air arriving on northerly winds as a result. As high pressure builds in at the surface, upper level disturbances will be passing by aloft. This means that some mid/upper level cloudiness is possible today, especially in the west, though most of the day will feature plenty of sunshine. Despite that sunshine, the colder airmass means highs won’t be all that warm today. Expect temps a little above 60 in the south and a little above 50 in the north. No precipitation is expected.

Cold Front To Cross The Region Today

Hello everyone!

A cold front is located to our northwest this morning, and will approach the area this afternoon before moving offshore tonight. This means that we’re looking at some low cloud cover this morning as the front moves moisture into the region. That low cloud cover is producing some drizzle this morning which should clear up a bit heading into the midday hours. However, not much in the way of sunny breaks will be found outside of the mountains and SW NH.

The front’s line of showers will arrive this afternoon, likely around 2 in the northern mountains. As the showers move southeast towards the coast, they’ll slow down and weaken as the front gets farther away from its parent area of low pressure in Hudson Bay. That said, folks in the south should expect at least the chance for showers this evening, even if it’s not guaranteed.

The low clouds will keep temps generally on the cooler side ranging from 60 in the northeast to 70 in the southwest.

Rain Departs Today But Clouds Remain

Hello everyone!

Today will feature the departure of yesterday’s rain, though a lack of strong, dry NW winds means that low clouds will be able to remain stubbornly in place for much of the day. The best chance for sun will be later this afternoon/evening along the coastal plain. Highs will be seasonably cool, ranging from the upper 50’s north to the mid 60’s south. After a few showers depart this morning, mainly dry conditions are expected.

Cool And Dreary Today

Hello everyone!

A warm front extends from Lake Ontario east through New York City and Nantucket this morning. If you draw that out on your mental map , you’ll see a big dip in the front east of the Appalachians. Longtime readers of this blog/watchers of Maine weather will recognize this signature as Cold Air Damming. In the wintertime, CAD brings notoriously hard to predict ice/sleet, but in the fall when temps aren’t cold enough for that yet, we just have dreary weather with cool temps and steady rain.

That steady rain is more in drizzle form than full on rain form this morning, but heavier precip will move in this evening as an area of low pressure approaches. Some embedded thunder is possible with that round of rain. Skies will be overcast today with the rain, which will also contribute to cool temps. Highs will range from the low 40’s in the north to the mid 50’s along the SE NH coastline. NE breezes will make those temps feel even a bit cooler than that. Enjoy!

Morning Rain Clears This Afternoon

Hello everyone!

Today will feature morning rain as a wave of low pressure develops and moves along a frontal boundary located overhead. Look for this rain to slowly settle to the south through the day today, eventually moving out of the area late this afternoon. Highs will be on the cooler side, generally sitting in the low 50’s for most of the area.

Another Seasonably Calm Fall Day Today

Hello everyone!

Canadian high pressure is once again in control of our weather today, with generally quiet conditions expected to continue. Skies are mainly sunny across most of the region this morning, but satellite imagery shows some clouds moving in from the west. Neither sun nor cloud will be able to take full control today, so we’ll be left with a mix of both. A slight westerly component to our winds will mean that upslope areas in the mountains will be more likely to see clouds, with downslope areas near the coast more likely to see sun. Highs will range from around 50 in the mountains to around 65 in the south. A brief shower is possible in the mountains later on today, but the vast majority of the area will be dry through the day today.

A Seasonable Fall Day Today

Hello everyone!

There’s not too much in the way of interesting things to say about today’s weather. A weak cold front is currently draped over the mountains, and will be drifting southeast across the area this afternoon. There’s very little moisture associated with the front, so a few scattered showers in the mountains will be about all that’s expected precipitation wise. Highs will range from the upper 40’s in the north to the mid 60’s in the south. As far as sky cover goes, expect a mix of sun and clouds with more sun closer to the coast, and more clouds as you head towards the mountains.
