Clouds increase again Friday night with a chance of snow and patchy fog developing after midnight, along with light snow accumulation and lows in the lower 20s. On Saturday, mostly cloudy skies persist with a chance of snow that may mix with rain during the afternoon as temperatures climb into the upper 30s. Light additional snow accumulation is possible. Saturday night remains mostly cloudy with another chance of snow developing, and overnight lows will fall to around 20 degrees.
Another storm system may affect northern Maine late this weekend into early next week, with the potential for winter weather and travel impacts. While details are still uncertain, current trends suggest a developing low pressure system could track near the Gulf of Maine by Monday morning. This type of setup often brings snow to northern areas, especially where temperatures remain cold enough to support all snow.
Although it is too early to determine exact snowfall amounts or timing, National Weather Service confidence is slowly increasing that a storm will impact the region. For northern Maine, this could mean accumulating snow and potentially difficult travel conditions sometime late Sunday into Monday. Residents should stay tuned for updates as the track and strength of the storm become clearer over the next couple of days.
By Monday, conditions trend drier with a mix of sun and clouds and only a slight chance of lingering snow. Highs will be near 30 degrees, followed by a cold Monday night with lows in the lower teens under partly cloudy skies. Tuesday looks quieter with mostly sunny skies and highs in the mid-30s, though clouds increase again Tuesday night. Another chance of snow arrives on Wednesday into Wednesday night, but at this point precipitation appears light, with seasonable temperatures continuing and overnight lows dipping into the 5 to 10 degree range.
🇺🇸 Today's US National Weather Outlook 🇺🇸 (click to expand/collapse)
An unusually strong and early season heatwave continues to build across the western United States and is expected to expand into the Great Plains over the next several days. Temperatures will climb well into the 80s and 90s, with some desert areas reaching above 100 degrees, setting numerous daily and even monthly records. This prolonged heat may increase health risks and accelerate snowmelt, leading to rising rivers and dangerous cold water conditions. Meanwhile, the Pacific Northwest will remain wet with periods of heavy rain and possible localized flooding. Farther east, weaker systems will bring a mix of rain and snow from the Great Lakes into the Interior Northeast, while conditions gradually warm along the East Coast.
Quiet
Weather Pattern Nationwide
with No Thunderstorms
Expected
A calm and stable
weather pattern is in place
across the United States today
and tonight, with no
thunderstorms expected. High
pressure over the Southwest
and a broad trough over the
eastern part of the country
are working together to keep
conditions dry and generally
quiet. The atmosphere lacks
the necessary ingredients,
such as moisture and
instability, needed to produce
thunderstorms. While a very
small chance of isolated
activity exists over southeast
Florida late tonight,
conditions there are still not
favorable enough to support
meaningful development.
Overall, much of the country
will experience a break from
active weather, with tranquil
conditions dominating from
coast to coast.
A surge of tropical moisture, often referred to as a Pineapple Express, will bring periods of heavy rain to western Washington on Thursday. This system will focus the heaviest rainfall over the Olympic Mountains and northern Cascades, where totals of 2 to 4 inches are expected. Rain may briefly ease Thursday evening before another round develops overnight. With soils already saturated from recent wet weather, much of the rainfall will run off quickly, increasing the risk of localized flooding. Urban areas and locations prone to flooding will be most vulnerable. While widespread severe flooding is not expected, isolated flash flooding and rising streams and rivers could create hazardous conditions.

Critical Fire Weather Conditions Develop Across Wyoming and High Plains
Dangerous fire weather conditions are expected to develop across central and eastern Wyoming today as a combination of strong winds, very dry air, and warm temperatures creates an environment favorable for rapid fire spread. Winds may gust up to 30 to 35 miles per hour at times, while humidity levels drop very low, allowing vegetation to dry out quickly and become more flammable. These conditions will also extend into parts of the northern High Plains, including areas of Montana, Colorado, South Dakota, and Nebraska, where elevated fire danger is expected. Portions of central and southeastern Oregon will also see warm, dry, and breezy conditions, increasing fire concerns. Outdoor burning is strongly discouraged.

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.
