Winds will be gusty at times, though not as strong as in Bangor or the coast. Even so, occasional gusts could bring down a few weakened trees, especially where the ground has softened from thawing and rainfall.
The main concern across northern Maine is water runoff. Smaller streams and poor drainage areas may see minor flooding as rain and snowmelt combine. River ice will begin to weaken and shift, which could lead to isolated ice movement, though widespread ice jam flooding is less likely than farther south. Conditions will gradually improve later today. However, much colder air moves in as the day progresses with daytime highs occurring this morning and temperatures falling through the day.
Today in Fort Kent and vicinity, expect cloudy skies this morning with partly sunny skies this afternoon. High in the mid-40s with southwest wind 15-20 mph gusting in the 25-35 mph range. 90% chance of rain this morning tapering to snow showers this afternoon with less than 1/10-inch precipitation anticipated. Patchy fog possible this morning.
High pressure moves east Thursday while an area of low pressure near James Bay tracks towards Québec pulling a cold front east and bringing increasing clouds and breezy south winds 10-15 mph with gusts to around 20 mph possible. High in the mid-30s with a 10% chance of snow by afternoon. Thursday night, mostly cloudy skies with a 60% chance of snow and temperatures in the lower 20s. South wind 0-7 mph.
Astronomical spring begins at 10:46 am Friday morning, but conditions will remain winter-like heading into the weekend and early next week. The weak system passing north of the region Thursday night into Friday is expected to bring a chance of snow, though how widespread or steady it becomes remains uncertain. At the very least, periods of light snow or a mix of rain and snow showers are likely, and a few brief heavier snow showers are possible. Any lingering showers may continue into Friday.
Another system may arrive Friday night into Saturday, bringing another round of light to possibly moderate snow. Confidence in exact timing and amounts remains low, but it could add to any existing snow cover.
By late weekend into early next week, a stronger storm may develop somewhere across the Northeast. While details remain unclear, this system has the potential to bring more widespread precipitation, most likely snow in northern Maine. The exact track will determine how significant the impacts become.
For now, a generally unsettled and seasonably cold pattern is expected across northern Maine from Friday through early next week, with periodic chances for light snow.
On Friday, expect a mix of clouds and some sunshine with scattered snow showers developing, possibly mixing with rain during the afternoon. Temperatures will reach the upper 30s, with a light west wind and occasional gusts. Friday night will turn colder, with mostly cloudy skies and a chance of light snow as lows fall into the upper 10s.
Saturday will be cooler, with partly sunny skies and another chance of snow showers. Highs will be in the low 30s. Snow chances continue into Saturday night under mostly cloudy skies, with lows dropping into the mid-10s.
Sunday brings more of the same, with partly sunny skies and a chance of snow. Highs will be in the low 30s, followed by mostly cloudy conditions Sunday night with lows in the low 10s.
By Monday, colder air settles in. Skies will be partly sunny with just a slight chance of snow, and highs only reaching the mid-20s. Monday night will be mostly cloudy and quite cold, with lows falling into the upper single digits to around 10°F.
A powerful storm is moving out of New England today, but strong winds and lingering snow showers will persist before gradually easing tonight. Behind it, a quieter pattern begins to take shape for much of the country. In stark contrast, an unusually early and intense heatwave is building across the western United States, with parts of the Desert Southwest reaching well into the 100s and threatening record highs. Meanwhile, the Deep South and Southeast are experiencing a sharp cold snap, with freezing conditions shifting east and possible record lows into Wednesday morning. Elsewhere, light snow spreads across the northern Plains into the Midwest, while the Pacific Northwest remains wet with periods of rain and mountain snow over the next couple of days.
Quiet Weather Nationwide
with Minimal Thunderstorm Activity
Thunderstorm activity is not
expected across the country today as a
strong storm system that brought severe
weather to the East Coast has moved
offshore. In its wake, a cold front is
bringing drier and more stable air
across much of the United States,
leading to generally calm conditions.
The only area with a slight chance for a
stray thunderstorm will be across
southern Florida and the Florida Keys,
where the front is lingering nearby.
Even there, any storms that develop are
expected to be isolated and mainly
remain offshore, with very limited
coverage. Overall, today will feature a
quiet weather pattern with no organized
thunderstorm threats expected.

🌧️Excessive Rainfall Outlook

Learn more about Excessive Rainfall Risk Categories
An active weather pattern will bring another round of steady, soaking rain to parts of Washington State as a moisture-rich system moves inland. The heaviest rainfall is expected across the Olympic Peninsula, the Chehalis River Valley, and into the northern Cascades, where widespread totals of 2 to 3 inches are likely, with locally higher amounts. Snow levels will be high, meaning much of the precipitation will fall as rain, even in the mountains, accelerating snowmelt and increasing runoff. While rainfall rates are not expected to be intense, the prolonged nature of the rain combined with already saturated ground may lead to rising rivers and minor flooding. A marginal flood risk is in place, especially for rivers and smaller streams.

Critical Fire Danger Develops Across Southern Plains
Dangerous fire weather conditions are expected today across parts of northwest Texas into southwest Oklahoma, where very dry air and increasing winds will create an elevated to critical wildfire risk. In the wake of a recent cold front, humidity levels have dropped significantly, with extremely dry conditions in place. As winds strengthen through the afternoon, especially across western Texas into southwest Oklahoma, any fires that start could spread rapidly. Gusty southwest winds combined with humidity as low as 10 to 15 percent will heighten concerns in this region. Surrounding areas of the central and southern High Plains will also see elevated fire danger, where dry conditions and breezy winds continue to support wildfire growth.

The vast majority of weather apps are automated without human oversight and can miss critical, nuanced details during severe or changing weather. Do not rely on an app for the forecast. Instead, go to weather.gov for the forecast.
Radar apps visualize precipitation intensity using color-coded echoes. However, updates are not instant, and even the most advanced composite radar mosaics can be delayed by 5 to 20 minutes by the time they reach your app.That delay means the weather you are viewing might already be miles away — or more intense than the image suggests.
