Chance of Strong Storms Today

Good morning! Quick update courtesy of being in a class with a computer and completing the original assignment.

With the cold front approaching New England, there will be a chance of showers and thunderstorms today. These storms could be strong to severe, mainly in northern New England, but there will still be a chance. No widespread severe weather is expected, but a few storms could approach severe limits. SPC has a marginal risk over northern New England today. Any severe storms would carry a primary risk of damaging winds, with isolated large hail not fully out of the question. A brief tornado cannot be ruled out, primarily across northern/eastern Maine where there will be decent helicities.

Some showers/storms have already fired west of New England, but are still a ways away; the closest one is along the International Border between New York and Quebec, southwest of Montreal. I can’t determine if the radar signal near Plattsburgh, NY is rain, biological signals, or something else.


SPC has put out a mesoscale discussion noting a severe thunderstorm watch is currently not expected due to the marginal/isolated nature of severe weather. Stay tuned for possible severe weather warnings.

A watch indicates the possibility of severe weather; a warning means it is imminent. Move indoors immediately when any thunderstorm – severe or not – approaches.

Have a good day!


Another Steambath Expected – Record Highs Possible

Good morning! Another record- or near-record hot one expected today. Today will bring mainly south-southwesterly winds today, with some showers possible across mostly northern New England, but southern New England could also get in on some showers.

Highs to range between either side of 80 in northern Maine, low 80s along the east half of the coast, to the mid 80s to low 90s, across central Maine and the western half of the coast, to the low 90s in interior southern Maine; between the mid 80s in far northern New Hampshire, to the upper 80s across most of the state, and low 90s in parts of central and southern New Hampshire. Mid 90s are not out of the question in the Merrimack Valley south of and including Concord. In Vermont, expect between mid 80s in the Northeast Kingdom and the mountains to upper 80s and perhaps an isolated 90 degree reading along the New York border, and the southern half of the New Hampshire border. In Massachusetts, highs to range from around 80 on Cape Cod, Martha’s Vineyard and Nantucket and the immediate south coast to the mid 80s along the inland south coast and the highest elevations of the Berkshires, and the upper 80s and low 90s across most of the rest of the state, including the east coast. Low 90s are fairly certain in Northeast MA and the Boston Metro, with some mid-90s readings not fully out of the question in the Merrimack Valley. Rhode Island will be in the mid 80s, with upper 70s and low 80s at the immediate coast and upper 80s and some low 90s in northern parts. Connecticut will be in the upper 80s in interior southern, mid 80s at the coast, and low 90s in the northern half.

Again, a mainly mostly sunny to sunny day. HIgher humidity for today is expected with dewpoints mainly in the mid to upper 60s (lower in northern Maine).

Have a good day!


Very Hot Day Expected

Good morning!

The same mainly west-based winds are expected today. The temperatures will rise a bit along with the humidity, and some extremely hot conditions are possible in some locations. Make sure to keep hydrated, or stay in an air conditioned area.

Highs to range from the mid/upper 70s in northern Maine, to the low 80s across central Maine and extreme northern New Hampshire as well as Cape Cod and the MA/RI islands; mid-80s across much of Vermont and along much of the coast; upper 80s across southern Maine, central New Hampshire, southern Vermont and the Berkshires and the east coast of Massachusetts; low 90s to prevail across a large portion of western and central Massachusetts, southern New Hampshire, interior southeast Massachusetts, interior Rhode Island, much of Connecticut. Mid 90s will prevail in interior Eastern Massachusetts, the Merrimack Valley in south central New Hampshire, and isolated parts of the Connecticut Valley south of Greenfield, MA. An isolated 98-100 reading is not immediately likely, but nonetheless cannot be ruled out in Northeast Massachusetts, where some towns are forecast to go as high as 97, based on 5 AM temps already in the lower to mid 70s for some.

Boston’s all time record is 95 for today – totally achievable in most of the city – but considering the weather station is right at the water (Logan Airport), that might not happen. But there are some factors going for it, including the coast will be barely relief.

Dewpoints will be between the mid 60s and low 70s, with reductions possible into the upper 50s to mid 60s possible late day. Heat index values will be in the upper 80s or 90s for most, with values near 100 where temperatures are the highest.

Skies will generally be mostly sunny to sunny for most. Scattered showers and thunderstorms are possible, mainly over Northern New England.

Stay safe in today’s heat. Stay in an air conditioned environment if possible, and if you cannot, drink plenty of water. Many schools predate the thought of air conditioning, making things worse due to the amount of people in the room at once. (Or, in my case, the school was expanded and basically rebuilt two years ago, on a 61% state funded overhaul, and there’s no A/C anywhere, except the main lobby and office. Good job, Dracut politicians.)

Have a good day!


A Beach or Cookout-Worthy Labor Day

Good morning!

The unofficial end to summer will bring conditions like that of midsummer, with sunny skies regionwide. With the wind no longer flowing onshore (now flowing from the west), summer conditions are primed to return. Today will be a perfect beach or cookout day.

Highs will range from the low to mid 80s in far northern Maine and far northern New Hampshire and the mountainous regions of Vermont, to the upper 80s across a large swath of central New Hampshire and not-as-far-north-but-still-northern New Hampshire, Vermont’s eastern and western borders, much of central and southeast Maine, the Berkshires of western Massachusetts, and areas near but not directly at south-coastal MA/RI/CT; lower 90s will prevail across most of Massachusetts, Rhode Island and Connecticut including much of the Boston metro; except the coast and the aforementioned regions. Highs may reach the mid 90s in the Connecticut Valley from Greenfield, MA to Hartford, CT, and the Merrimack Valley from the Concord, NH area to just east of Lawrence, MA.

Along the coast, between the low 80s in downeast Maine to the mid and upper 80s across southwest Maine, NH, and eastern MA coasts including much of Boston proper; back to the low 80s directly at south-coastal MA/RI/CT, except mid-80s in the NYC metro coast of southwest Connecticut. Cape Cod and the MA/RI Islands will stay in the 70s. Away from SE MA/RI/CT, areas just inland may be in the low 90s.

Generally sunny skies to prevail throughout much of the region. However, some clouds are possible across far northern New England associated with showers in southern Quebec, which may cross the International Border into mostly northern Maine but a shower cannot be ruled out across northern NH and northern VT,

Have a good Labor Day!


Cool Day Today

Good morning! Apologies for the late blog post; no school today and my 6-year-old sister has been trying her best to bother me!

Anyways, today will be dominated by a northeasterly flow bringing much cooler and drier conditions to New England. Highs will range from the upper 60s in Northern Maine; low 70s across the east coast of MA/NH/coastal ME; low to mid 70s across much of the rest of Maine, New Hampshire, Vermont, and Massachusetts; south coastal MA, RI, CT will stay in the lower 70s along with Cape Cod and the MA/RI Islands. Interior RI, and Northeast and Northwest CT may reach the upper 70s, with interior Southern CT and the Hartford area around 80. Mostly sunny skies will prevail.

Have a wonderful day!


[2:35 PM] Isolated Strong to Severe Thunderstorms Today

[2:33 PM] Quick update. As expected, a few thunderstorms developed. Earlier, these were generally expected to be isolated thunder/fairly weak, and mostly in southern NH and MA. As it turns out, there are two severe thunderstorm warnings in Maine, and another storm near severe limits in Maine and two others along the ME/NH line holding similar status. Radar as of 2:33 PM:

235 pm

Stay safe. I will be tweeting warnings on @ncoram_wx – also stay tuned to local media for urgent updates. There is also a strong/severe storm near the NY/VT border.


Backdoor Cold Front; Relief After Today

Good morning! Today will feature some more clouds, and a chance for some thunderstorms, especially in northern MA and southern NH. Winds will generally turn north or northeast, mostly light; some spots up to 10 mph with some exceptions. Nonetheless, mainly high clouds are expected for those who see clouds and it will remain mostly sunny to sunny.

Highs today will range from the mid to upper 60s in far northern Maine to around 90 in the Connecticut and Merrimack river valleys; in between, low 70s are likely throughout more of the northern half (but not necessarily far-northern) of Maine, with upper 70s to mid-80s in southern Maine, warmer as you get closer to the coast (but cooling off at the immediate coast, to high temperatures in the mid to upper 70s.) Across New Hampshire, highs will range from the mid to upper 70s in northern New Hampshire, to the low to mid 80s across central New Hampshire, and the mid 80s across most of southern New Hampshire (with upper 80s and perhaps a 90 reading in the Merrimack River Valley from Concord south to the MA border); highs will be in the upper 70s at the coast. In Vermont, lower to mid 80s along the western and eastern state borders, and around 80 elsewhere. In Massachusetts, highs range from the upper 70s on outer (eastern) Cape Cod, Martha’s Vineyard and Nantucket to the low 80s on the remainder of the coast (including southern/western Cape Cod); low 80s also prevail in parts of the Berkshires. Mid 80s to be the rule across western Mass., as well as areas near but not right at the coast plus southeast Massachusetts; upper 80s will be widespread across central and northeast Mass. and much of the Boston metro. Upper 80s and low 90s to prevail across the Merrimack Valley west of Lawrence, and the Connecticut Valley south of the Vermont/NH tripoint. Rhode Island will range from 80 to 90, lowest south, highest north. Connecticut will be ranging from the mid 80s to 90, except around 80 at the coastline – warmest temps along the Connecticut (River) Valley.

A backdoor cold front for most today will bring relief tomorrow in the form of much cooler temperatures.

There will be a chance of thunderstorms, particularly in S. New England and the southern third of N. New England; no severe weather is expected, as these storms will mostly be triggered by some instability aloft, with little shear to work with.

The HRRR shows these as mainly harmless showers in mainly southern NH:hrrr_ref_boston_16

No less, lightning is a leading killer; if you can hear thunder, you are close enough to be struck by lightning. Heavy rain and gusty wind can’t be ruled out either.

Have a good day!
