The latter part of this week will be somewhat significant for me personally as I (finally) turn 21 and graduate college. Thus it seems like as good a moment as any to hang up my hat as a daily Maine weather guy. I’m excited to play nomad for the next year or so while working remotely part time before I venture off into the “real world” for good, and such a lifestyle doesn’t necessarily fit well with opening my laptop every morning.
It’s hard to believe this modest blog started over a decade ago when my dad urged my ten-year-old self to ditch my previous blogging endeavor for something more professional. This little project has been by my side through quite a lot from the pre-Halloween snowstorm of 2011 when I was just starting the long slog of middle school to the blockbuster winter of 2014-15 when the “cool kids” realized snowday prediction made me (somewhat) useful to the nor’easters of March 2018 as I tried to figure out where I’d go to college to now, just a couple humid days before I’ll finally be able to officially call myself a meteorologist.
Many of you have been along for much of this ride too, and have offered words of encouragement that have meant the world to me. In 2018 when I headed off to college I thought about writing a post like the one I have now before my dad once again had a smart suggestion: maybe the good forecast-seeking people of western Maine and New Hampshire could bribe me with some pizza and textbook money to stay on the job. Well, it worked. I’m very grateful for all that folks have chipped in over the last four years to keep this little project running. I have turned off the Patreon as of this morning. Perhaps I should have done it a while ago- after all, there are many more deserving of your dollars than I.
I could go on reminiscing about the adventures I’ve had trying to forecast Northern New England’s fickle weather and all that I’ve learned in the process, but this rambling has gone on long enough. Thanks for a great run everybody! If you’re looking for reliable local weather info aside from our excellent local TV stations and the NWS, check out Mike Haggett’s Pine Tree Weather blog. He and his crew do a great job!
With that, here we go one last time.
Today will feature continued cool and mostly clear weather as Canadian high pressure settles overhead. Northeasterly winds this morning will shift to the east this afternoon leading to falling temperatures and some patchy stratus/fog near the coast. Another batch of clouds may approach from the north this afternoon ahead of a weak frontal boundary. Thus the north and coast will be coolest today with highs in the mid to upper 50s while the foothills in between remain sunnier and warmer with highs in the mid to upper 60s.
Fantastic weather is on the docket today as Canadian air reclaims its rightful place in New England. Look for breezy north-northwesterly winds to push cooler and drier air into the region today. Satellite imagery this morning shows a bit less cloud cover than guidance expected. The morning looks more sunny than cloudy across most of the area with the exception of some cirrostratus near Mt Washington and a bit of stratocumulus northeast of Jackman. A modest surge of mid-level moisture this afternoon may support some more widespread mid/upper-level clouds for the latter half of the day. High temperatures today look delightful, ranging from around 60 in the mountains to the low 70s along the southern coast. The northerly breezes should do a pretty good job keeping sea breezes at bay, though winds may turn onshore in southern York County as well as along the southern Midcoast peninsulas.
Today will feature hot, humid, and stormy weather as a tropical airmass continues to move in from the southwest. Just like yesterday, we’ll start the day with marine stratus and fog especially along the Maine coast. Stratus and fog will burn off from west to east during the next few hours, becoming confined to the immediate shoreline by noon. If you’re south and east of Route 1, you’ll enjoy a cool day in the marine layer with mostly cloudy skies and high temps in the mid 50s to low 60s. To the west though, it’ll be friggin hot bub. Low to mid 90s are in store for New Hampshire with only marginally cooler air across interior Maine (mid to high 80s). Dew points will surge towards 70 especially in Maine (the heat will be *a little* drier in NH).
The combination of high temps and sultry humidity will provide ample fuel for thunderstorms this afternoon. What we’ll largely be missing is forcing for storms to get going in the first place. That should arrive by mid afternoon as a weak pre-frontal trough interacts with the mountains. Look for showers and storms to go up along and north of the Route 2 corridor by 2-3 PM before moving slowly east-southeast. The atmosphere isn’t nearly as volatile as it was yesterday, but damaging winds and small hail are possible with today’s storms and a tornado can’t be ruled out in the more northern mountains (maybe the moose will report if there’s any damage).
The cold front ultimately responsible for this miserable hot air will approach the region from the west around sunset. A line of showers and thunderstorms from VT/NY will comprise its vanguard, though instability will be waning after sunset and severe weather is less likely with this round of activity. Still, for the coast and southern foothills that are likely to miss out on the early afternoon storms, the frontal line will provide the better shot for some needed rain and perhaps a rumble or two of thunder.
Cooler and drier air will pour into the region behind this front overnight.
A tragically hot and humid airmass will be encroaching on our area today as a warm front doggedly staggers northeast. Defending our right to exist in a sweat-free state should we choose will be easterly onshore breezes and a thick stratus deck. As I write this a little before 8 AM, defensive lines have been drawn along the spine of the Green and White mountains with thick low clouds firmly entrenched to the east. As the day goes on, the low cloud deck will come under fire from the strong May sunshine and developing southwesterly breezes. As a result, most of New Hampshire and a good part of northwestern Maine will be firmly under enemy control by the afternoon while southeasterly breezes keep the good times rolling along the coast. High temperatures will range from the low 90s in the CT and Merrimack valleys to the low 50s along the shoreline especially closer to Penobscot Bay. Clouds will hang tougher along the coast and east of Augusta while western areas see widespread sunshine after the morning fog burns off.
Some showers and thunderstorms are possible in the mountains this afternoon as activity from upstream in Quebec moves southeast. The most likely time for storms will be after 5 PM. We’re seeing a very unusual plume of thunderstorm rocket fuel (technical term) move across the area today thanks to rapidly cooling temperatures with height in the middle of the atmosphere. As a result, thunderstorms this evening could pack quite a punch. Be ready for frequent lightning, strong winds, and hail. A tornado can’t even be ruled out entirely. Storms are likely to remain mostly north of Route 2 with the odds getting rapidly slimmer farther southeast.
Today’s forecast is all about location, location, and location. The region will be roughly split in two by a warm front advancing slowly from the southwest. In Maine, largely ahead of the front, southeast winds will push cool maritime air onshore. As a result, morning stratus and fog will be slow to lift inland and will remain locked in place along the coast. Temps will range from 50 near Rockland to 65 or so in the mountains where partial sun will emerge this afternoon. To the west in New Hampshire, largely behind the warm front, morning stratus and fog will burn off to partly cloudy skies this afternoon. Temps will rise into the low to mid 70s and dew points will creep up towards 60 as winds shift to the south and southwest. Heat and humidity will invade further tomorrow, the coast still looks to be in pretty good shape with onshore southerly winds.
Today will feature cooler temps and showery weather as a warm front approaches from the southwest. Look for morning sunshine in the north and east to give way to clouds over the next couple hours before rain arrives from southwest to northeast around lunchtime. Rain will continue through much of the afternoon before tapering off around sunset. High temps will generally range from the low 50s in the mountains and right along the shoreline to around 60 between Lewiston and Augusta.
Cooler and drier air will be moving in on northwesterly breezes today. Some leftover moisture in the low to mid levels has led to some cloud cover mostly over Maine, especially in the north and east. That should fade away in the coming hours as drier air moves in. The result will be a generally clear, cooler, and drier day with high temps ranging from the low 50s up in the mountains to around 70 along the southern coast where sea breezes will be suppressed by the prevailing northwesterly wind.
Cooler and drier air is slowly working its way into the region from the west this morning behind the cold front that brought showers and thunderstorms last night. Westerly winds will be the name of the game for most of today which means the coast will actually see its warmest day in a while with temps ranging from 60 up near Rockland to 65 in Portland. Temps will gradually slide into the low 50s up in the mountains.
A secondary cold front will approach the region from the northwest this afternoon. That means that clouds will increase especially up in the mountains, and some showers will begin popping up in the same area. Showers will struggle to move into the drier air over the coastal plain, but anyone is at some risk for raindrops this afternoon. If you’re up in the mountains, it may feel more like a rainy day with frequent shower activity. Showers will die down around sunset.
Today will once again feel a lot like summer as warm and humid air moves into the region. Most of us will start off under some stratus and perhaps even some fog this morning but that will burn off by this afternoon for everyone not right along the coast. Onshore southeasterly flow will keep the coast socked in with stratus and fog while temps get stuck in the low to mid 50s. Farther inland, mostly sunny skies will push temps into the mid to upper 70s with fairly humid dew points in the 60s.
A cold front will approach from the west this evening. Some showers and thunderstorms will pop up ahead of the boundary in western NH this afternoon but the main line of storms won’t arrive until around sunset. It will be quickly weakening as it moves towards the stable maritime airmass, but some gusty winds are possible especially in NH.
It brings me no joy to say this, but today will feel a lot like J*ly as southwesterly breezes push hot and humid air our way. Look for abundant sunshine this morning to quickly push temps into the 80s away from the midcoast by midday. Inland areas will continue climbing into the high 80s/low 90s this afternoon as a sea breeze provides much-needed relief along the coastline. Afternoon clouds will bubble up with a bit more depth today, resulting in some scattered showers and perhaps even a thunderstorm or two especially inland. Showers are most likely between 1 and 7 PM, but not every town will see one given the lack of forcing for ascent under the high pressure system generally running the show across this part of the country.
