Today – Wednesday

Low pressure will cross southern Maine this afternoon and move into New Brunswick tonight and drift east in the Maritimes Tuesday bringing clouds and rain to Fort Kent and vicinity today. Clouds diminish this evening as high pressure builds in tonight into Tuesday morning with partly cloudy skies tonight and mostly sunny conditions Tuesday AM.

Meanwhile, low pressure near James Bay will track across Québec Tuesday into Tuesday night and cross the Valley Wednesday. This system will bring increasing clouds and the likelihood of showers and scattered thunderstorms to the SJV Tuesday afternoon into Tuesday evening. A slight chance of showers persists overnight with another round of showers and isolated afternoon thunderstorms Wednesday. Scattered showers linger Wednesday night as an upper trough/low moves across the region.

Today features rain with a 100% chance of precipitation with between 0.25 and 0.50-inch rainfall expected in Fort Kent and vicinity. High in the mid-50s with southeast winds around 6 mph falling to near calm by evening. Precipitation tapers off this evening. Tonight, low pressure and associated troughs move east with partly cloudy skies overspreading the SJV. Chance of rain is 20%, ending in the evening. Low in the upper 40s with near calm west wind. Some patchy fog is possible overnight.

A warm front slides across the SJV Tuesday with mostly sunny skies early becoming mostly cloudy by afternoon. High in the mid-70s with an 80% chance of mainly afternoon showers and scattered thunderstorms. Rainfall totals in the 0.10 to 0.25-inch range with locally higher amounts possible in any storms. West wind near calm in the morning becoming south-southwest in the afternoon at 4-5 mph.

For Tuesday night, a 90% chance of showers with a slight chance of evening thunderstorms is expected for Fort Kent and nearby communities. Temperatures fall into the lower 50s with winds becoming west 0-5 mph. Rainfall totals between 0.10 and 0.25-inch expected, except for higher amounts possible in any thunderstorms.

Partly sunny skies develop Wednesday with a 50% chance of showers and a chance of isolated afternoon thunderstorms with rainfall amounts in the 0.01 to 0.09-inch range, with locally higher totals possible in thunderstorms. High in the low 60s with northwest wind 5-10 mph. Wednesday night, partly cloudy with a 30% chance of scattered showers. Temperatures in the low 40s with north wind 0-7 mph.

Thursday – Sunday

A persistent omega block sets up across North America as the week progresses. This will tend to keep upper-level troughing and unsettled weather across the Saint John Valley for the mid- to late week period.

Partly sunny skies on Thursday will give way to a chance of showers during the afternoon and evening hours as highs reach the mid-50s. Northerly winds will remain light. Mostly cloudy conditions are expected Thursday night, along with a slight chance of lingering showers and lows in the low 40s.

Unsettled weather will continue into Friday with a chance of showers under partly sunny skies. Afternoon temperatures will climb into the upper 50s to around 60. A chance of showers will persist Friday night as mostly cloudy skies continue and lows settle into the low 40s.

Another round of scattered showers and a few thunderstorms is possible on Saturday beneath partly sunny skies, with daytime highs in the upper 50s. Any lingering showers or thunderstorms Saturday night will gradually diminish, followed by partly cloudy skies and overnight lows in the low 40s.

Conditions improve somewhat on Sunday with mostly sunny skies and only a chance of passing showers. High temperatures will reach the low 60s. A slight chance of an early evening rain shower will remain Sunday night before partly cloudy skies take over, with lows again falling into the low 40s.

The National Weather Service forecast office in Caribou notes that "[t]he chance for seeing patchy frost on at least one of the nights Thursday night to Saturday night is around 40 percent in the north and ... a little high elevation snow [is possible] in this weather pattern," so those with agricultural/planting interests should monitor the late week forecast for expected overnight conditions.

🇺🇸 US National Weather Outlook 🇺🇸

Heavy Rain in the South, Building Western Storms, and Dangerous Northern Plains Heat
Heavy rain and thunderstorms will continue across much of the South through midweek as a stalled front interacts with deep tropical moisture and unstable air. Repeated rounds of storms may produce flash flooding, especially in urban and low-lying areas from the Gulf Coast into the Southeast, while parts of Texas could also see severe thunderstorms capable of large hail, damaging winds, and isolated tornadoes. Farther west, conditions will turn increasingly unsettled as a large Pacific storm system spreads showers and thunderstorms across the Pacific Northwest and Great Basin through late week. Cooler air may even bring light snow to the highest mountain peaks. Meanwhile, dangerous early season heat will build across the northern Plains and Upper Midwest, where highs well into the 80s and 90s could create hazardous conditions for those unaccustomed to summerlike temperatures.

Marginal Risk for Isolated Severe Thunderstorms Tonight
Scattered strong thunderstorms may develop late this afternoon and continue tonight from parts of the Rio Grande Valley into sections of the central Plains and Upper Great Lakes. The overall threat for widespread severe weather remains limited, but a few storms could produce damaging wind gusts and hail. The greatest concern in the Plains stretches from Nebraska into southern Minnesota, where warm afternoon temperatures and increasing moisture may allow isolated severe storms to form. Parts of southwestern Texas and nearby New Mexico could also see strong winds with storms developing near the Rio Grande. In the Upper Great Lakes, isolated thunderstorms are possible near northeastern Minnesota. Many other areas across the country should experience weather with isolated showers or thunderstorms.

Slight Risk of Flash Flooding from the Gulf Coast to the Southern Appalachians
Periods of heavy rain and thunderstorms are expected today and tonight from the central Gulf Coast into parts of the Southeast and southern Appalachians. The greatest flash flood threat extends from southeastern Louisiana through Mississippi, Alabama, Georgia, and into the Carolinas, where repeated storms may produce several inches of rain in a short time. Urban areas and locations with poor drainage are especially vulnerable to flooding. Additional heavy rain is possible across parts of Virginia and the Mid Atlantic, where slow-moving thunderstorms could lead to localized flooding concerns. Farther west, scattered storms in Texas and New Mexico may also produce intense downpours and isolated flash flooding. While flooding will not occur everywhere, conditions support localized areas of dangerous high water.

Critical Fire Weather Threat in Northwestern Nevada and Southeastern Oregon
Dangerous fire weather conditions are expected this afternoon across parts of northwestern Nevada into southeastern Oregon as strong winds, low humidity, and dry vegetation combine to increase wildfire danger. Southwest winds of 20 to 25 miles per hour, with higher gusts, will create conditions favorable for rapid fire spread. Hot temperatures and very dry air will further worsen the threat across the Great Basin. Elevated fire danger will also extend into nearby areas where dry conditions and gusty winds persist. Farther south across Arizona and New Mexico, isolated thunderstorms may develop during the afternoon and evening. Some storms could produce little rainfall while generating lightning and gusty winds, creating an additional risk for new wildfire starts in dry and vulnerable areas.

How accurate are forecasts? On average, for the first 72 hours the accuracy is 90 percent. For days 4-7 it is 70 percent. After seven days, it is 50 percent—just good for indicating trends. On social media and other similar sites, posts that show a forecast model run a week out are just for clicks and likes, and are not considered reliable.

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.
