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.
Today will feature another day of cooler temps and quieter weather as we sit on the southwestern edge of a large upper level low anchored in SE Canada. Expect mostly sunny skies to start the day for just about everyone outside of the mountains where some residual upslope cloudiness will be slow to burn off. As the day goes on, warmer air will try to push in from the SW which will result in increasing cloud cover for the entire region. Any precipitation this might produce will evaporate before it hits the ground as we continue to enjoy dry westerly flow. The best chance for a few drops this afternoon/evening will be in the mountains.
High temps today will remain cool, ranging from 50 in the north to 65 along the coastal plain. Similar to yesterday, large scale westerly flow will keep any sea breeze attempts at bay.
If I had to design a perfect day of weather for the time between Memorial Day and Labor Day, it would look a lot like today. A little morning fog along the midcoast will burn off in the next few hours, which means the entire area will enjoy some beautiful sunshine. As the day progresses, clouds will pop up in the mountains and adjacent northern parts of the foothills. Those clouds will develop into showers and some thunderstorms later this afternoon.
The best chance for a shower or storm will be north of Route 2, though places as far south as Brunswick-Lewiston-Fryeburg shouldn’t be surprised if a brief shower pops up. Clouds that develop this afternoon farther south might manage to get a drop or two to the ground, but otherwise won’t be capable of producing much precip. Clouds and showers will both dissipate this evening with the loss of daytime heating.
High temps today will range from 50 in the northern mountains to 70 for a few lucky spots along the coastal plain. Any attempts at a sea breeze will be held back by a 20-25 mph WNW wind, which will allow even the shoreline to enjoy the warmer temps.
Today will feature more unsettled weather conditions across the area as we’re stuck between two low pressure systems. We’ll be looking at onshore flow as a result of this setup, which will bring cloudy skies and some drizzle/fog to the coastal plain, and generally cooler temps for all. The one exception to this will be in SW NH where a warm front should move far enough north to change winds to the southwesterly direction, and allow for some warmer temps and brief breaks of sun. High temps along the coastline will sit in the low to mid 50’s. Low 60’s can be expected for most of the rest of the area, with low to mid 70’s in the SW NH warm spots.
The difference in temps/sunshine between western NH and Maine will contribute to a difference in precipitation forecast this afternoon/evening. A cold front currently in New York will be looking to generate some thunderstorm activity to our west this afternoon. The front will arrive with thunderstorms in tow along the CT River around 3-4 PM. The warmer temps in this area will allow the thunderstorms to remain widespread in coverage. As the storms move east and encounter the stable marine layer, they will begin to fall apart leaving only scattered showers for Maine this evening.
Clouds will be on the increase today ahead of an approaching upper level disturbance. Those clouds, along with developing onshore flow, will keep temps a little bit lower than yesterday. Look for highs ranging from the low 50’s along the coastline to around 60 in the mountains to the low 70’s in the typical SW NH warm spots. Along with the increase in onshore flow will come an increase in fog along parts of the coastal plain, so keep that in mind if you’re thinking of heading out on the water. Most of us will remain dry today outside of a stray evening shower over western NH.
Today will feature weather that is, perhaps remarkably for the last few weeks, actually nice. Look for morning low clouds and fog over the coastal plain to burn off in the next few hours, leaving mostly sunny skies across the area for the rest of the day. That sunshine will push temps into the upper 50’s for the north and the lower 70’s for the typical interior SW warm spots. Cooler temps will also be found along the coast where a sea breeze will develop this afternoon.
Get out and enjoy the lovely weather while it’s here, another cool and unsettled stretch appears to be headed our way in the next several days.
Today will feature slightly warmer temps and slightly sunnier skies as southwesterly flow develops ahead of a cold front over Quebec. While unfortunately I can’t promise bluebird skies until tomorrow, most areas should leave yesterday’s deep gray behind. Temps will respond accordingly away from the coast, rising into the upper 60’s/low 70’s for most. The midcoast will remain much chillier in the low to mid 50’s. Some showers will move into northern areas this evening, but the vast majority of the day will be dry.
We’ll be returning to a familiar pattern today with cool temps and widespread cloud cover behind a departing storm system. Given that the storm is off to our east, we’ll be mostly precip free today with the exception of some drizzle this morning. The clouds will be most widespread this morning, and we’ll likely see some spots enjoying sunnier skies by this evening. The best odds for sunshine will be found across northern and western areas, with the coastal plain most likely to remain cloudy. High temps will be kept cool by the clouds and light onshore flow, ranging from the low to mid 50’s across most of the coastal plain and foothills to the low 60’s along the CT river where some breaks of sun are more likely.
Today will feature a brief return to the cooler and unsettled pattern we’ve all grown so tired of in recent weeks as low pressure tracks off to our south. Morning sunny breaks in eastern parts of the area will become obscured by cloud cover over the next couple hours, and overcast skies will continue through sunset. Rain will arrive from west to east during the midday hours, beginning in W NH between 9 and 11 AM before moving into Maine between 12 and 2 this afternoon. Rain will slowly taper off this evening from west to east.
A cold front has moved offshore as of this morning, and we’ll get to enjoy a nearly perfect day of weather today as a result. Expect mostly sunny skies across the area, with the only exception being far northwestern parts of the mountains near the Canadian border. Temps will be on the cooler side thanks to the northern source of the incoming airmass. Look for highs ranging from 50 in the north to a little over 70 in the south. Get out and enjoy the wonderful weather, we’ve earned it!
Today will feature the chance for showers and thunderstorms across northeastern parts of the area as a weak cold front slides through. Areas of clouds rain associated with the warm front will continue to impact coastal areas for the next few hours. Then we’ll see drier and sunnier conditions moving in from the west for the midday hours. That sunshine will push temps up into the 70’s for most areas away from the mountains and immediate coast. A few of the typical SW warm spots will make a run at 80. Those warm temps will combine with slightly muggier dew points to fuel the incoming thunderstorms this afternoon. Storms will develop around noon in the northern mountains before working their way southeast through the afternoon. Not everyone will get a storm, but those that do will experience heavy rain, lightning, and gusty winds. At this point, no organized severe weather is expected, but some storms could become severe if more sunshine develops in those northeastern spots. As you move SW, there’s less in the way of upper level dynamics to initiate and support thunderstorms, which should leave places SW of Portland mostly dry.
