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.

Improving Weather Today

Hello everyone!

Today will feature improving weather as low pressure moves from the Mid Atlantic to the Canadian Maritimes. When the low is to our southwest this morning, expect fairly steady rain. Once the low is northeast of us this afternoon/evening, expect rain to end with clearing skies. Most of the area should actually be sunny by sunset. Northeast winds will be in place ahead of the low for most of the day, which combined with the cloud cover will keep temps down. Look for high temps to fall within a few degrees of 60 across most of the region.

Pleasantly Cool Weather Today

Hello everyone!

Today will feature pleasantly cool weather as Canadian high pressure builds in behind last night’s cold front. Highs will range from a little below 60 in the north to a little below 70 in the south. Skies will feature increasing cloudiness as an area of low pressure approaches from the southwest. The rain from that system will hold off until early tomorrow morning, with dry conditions expected today.

Afternoon Showers And Thunderstorms Today

Hello everyone!

A cold front is approaching the area this morning, but won’t actually arrive until early this evening. This means that we have all day for patchy sunshine to heat the atmosphere up. The energy we get from sun at the end of September is a far cry from what it is in the early summer, but it will be enough to push temps into the upper 70’s for most of NH and western Maine. Cooler temps will be found northeast of Portland, with highs around 70.

We’ll be mostly dry through most of the day today, with storms along the front arriving in the form of a line. This line will first arrive in the mountains this evening, between 6 and 7. The line will then move east, reaching the coastal plain between 9 and 10. Storms will weaken as they move towards the midcoast just prior to midnight. The main threat from storms today will be strong gusty winds, that could cause some localized power outage issues.

Cooler and drier weather will arrive tomorrow post-front.

Cool And Rainy Today

Hello everyone!

Cool temps and overcast skies will prevail today as rain overspreads the area from southwest to northeast. It’s already raining in southwestern NH, and rain should arrive in Maine a little before noon. Northeastern parts of the region will see rain by the middle part of the afternoon. That rain will be of the steadier variety, with some heavier pockets possible especially in the mountains/CT river valley. High temps will be quite cool today with cold air damming eroding very slowly. The warmest temps in southeasterly flow will be near the coast, around 60, while the mountains hang on to that cooler air with highs just shy of 50. Rain tapers off later tonight.

Considerably Cooler Today

Hello everyone!

Today will feature the coolest temps most of us have seen in a while, both this morning with low temps and this afternoon with high temps. Many mountain areas are below freezing this morning, with temps near 50 along the coast. Temps in the north this afternoon will struggle to reach the 50 degree mark, while temps in the south will only rise marginally above it. The warmest spot today will be the CT river valley, where highs around 55 are expected. Skies will start out mainly sunny, with some high clouds moving in from the west this afternoon/evening.

Cool And Dry Today

Hello everyone!

Today will feature cool temps and dry weather as Canadian high pressure builds into the region. Look for highs ranging from the low 50’s in the north to the mid 60’s in the south. Skies will feature more sun than clouds this morning, but a cold front approaching the northern mountains will result in increased cloudiness this afternoon especially in that area. Little to no precipitation is expected today, outside perhaps of a brief evening shower associated with that front in the north.

A Proper Welcome For Autumn Today

Hello everyone!

According to the astronomers, fall begins this evening a little before 10 PM, and conveniently enough, Mother Nature appears to be on the same page. We’ll see our classic upslope/downslope pattern set up with low clouds hanging tough over the mountains, and clearer skies near the coast. High clouds will continue to filter overhead today, so even along the coast, sunshine will be filtered at best. High temps will draw similar lines, with low 50’s in the mountains, and mid 60’s near the coast. Aside from a brief shower possible in the upslope areas, dry weather will prevail across the region.

Breezy And Cloudy Today

Hello everyone!

A warm front is working its way through the region this morning. Showers and thunderstorms along that front will work their way into northern areas later on this morning into this afternoon. For southern areas, mostly dry weather is expected with more clouds than sun. You’ll also notice southerly winds pick up as the front establishes itself to the north. Gusts over 30 mph are expected across the area, with higher values in the higher terrain. High temps will range from 55 in the north, to around 70 in southern NH. Showers and storms are possible tonight as a strong cold front moves through, but due to the early morning timing of the frontal passage, no severe weather is expected.

Cool And Cloudy Today

Hello everyone!

Today will feature cool temps and cloudy skies as low-level moisture remains trapped over the region. Look for some patchy sunshine to develop beginning in northeastern areas this afternoon, but overall, overcast will be the rule. Overcast skies combined with northeast winds will result in cool temps, with highs generally in the low to mid 60’s. Some drizzle is possible this morning, but otherwise mainly dry conditions are expected.

Cooler And Cloudier Today

Hello everyone!

Today will feature cooler and cloudier weather as a backdoor cold front has now finished working southwest through the area. Behind that front, low clouds are present with NE winds bringing in cooler air. Ahead of the front in SW NH, warmer and muggier conditions remain intact. The terrain of SW NH will likely stop the boundary from making much more southwestward progress, and the combination of the terrain plus the front will likely be just enough forcing to drive a pop up shower or two this afternoon as highs rise into the mid to upper 60’s.

Elsewhere, look for more clouds than sun with much cooler temps in the low 60’s. The mountains and northeast will be even cooler than that, with highs in the low to mid 50’s.

Enjoy the cooler weather!
