Sunny Start, Stormy Stretch: Your 7 Day Weather Outlook
A quiet, bright start will not last all week. Central New York gets a pleasant opening stretch with sunshine, light winds, and seasonable warmth, but the pattern turns more unsettled by Sunday afternoon and Sunday night. After that, the forecast settles into a familiar rhythm: dry breaks, mild afternoons, and a few rounds of showers worth planning around.
For the Canastota area and nearby parts of Central New York, the biggest weather story is timing. Today looks like the best day for outdoor plans once early fog lifts. Sunday starts dry for many spots, then turns wetter late. Sunday night brings the most widespread rain chance of the outlook. The middle of the week brings another shower risk, especially Wednesday night.
The quick forecast at a glance
The week opens with calm weather, then shifts into a stormier setup late Sunday into Sunday night. Temperatures stay mild overall, with highs mostly in the upper 70s to lower 80s and overnight lows ranging from the mid-50s to mid-60s.
Day | Forecast | High | Low | Rain chance |
Today | Areas of fog before 8 a.m., then mostly sunny | 79 | 55 tonight | Low |
Sunday | Increasing clouds, showers and thunderstorms late | 82 | 65 Sunday night | 60% day, 90% night |
Monday | Partly sunny, chance of showers and storms | 80 | 58 | 30% |
Tuesday | Sunny and quiet | 80 | 58 | Low |
Wednesday | Mostly sunny, showers possible after 2 p.m. | 83 | 62 | 40% day, 60% night |
Thursday | Partly sunny, chance of showers | 78 | 55 | 30% |
Friday | Mostly sunny and comfortable | 76 | Not listed | Low |
The most useful takeaway is simple: today and Tuesday are the cleanest outdoor days, while Sunday evening and Wednesday night deserve the closest attention if plans involve travel, sports, yardwork, or events outside.
Rainfall amounts Sunday afternoon may stay light for many locations, generally less than a tenth of an inch. Thunderstorms could bring locally higher totals. Sunday night looks wetter, with new rainfall generally between a tenth and a quarter of an inch, again with higher amounts possible in thunderstorms.
That does not point to a washout every day. Instead, it suggests a forecast with clear windows between rounds of showers. Planning around those windows will make the week easier.
Today brings the best start after early fog
Today begins with areas of fog before 8 a.m., especially in the usual low spots and sheltered areas. Fog can vary a lot over short distances in Central New York. One road may be clear while the next valley or field edge has reduced visibility.
If heading out early, leave a little extra room between vehicles and use low beams if fog is thick. Once the fog lifts, the weather improves quickly.
The rest of the day turns mostly sunny, with a high near 79. Winds stay light, starting calm and becoming northwest around 5 mph in the afternoon. That is gentle enough that it should not cause much trouble for outdoor work, decorations, small boats on sheltered water, or patio plans.
For late-season warmth, this is a comfortable setup. The air should feel mild rather than hot, and the light northwest breeze will help keep the afternoon pleasant.
Tonight stays mostly clear with a low around 55. Calm wind returns, which can make the evening feel cool after sunset. It is a good night to open windows for fresh air, though spots that cool quickly may feel chilly toward dawn.
Best uses for today
Mowing, trimming, and garden cleanup after fog dries out
Outdoor sports and practices
Porch, grill, or backyard plans
Short trips before the wetter Sunday pattern arrives
Sunday turns more active late in the day
Sunday starts with a warmer feel and increasing clouds. The high reaches near 82, and winds turn a bit more noticeable. An east wind at 5 to 9 mph becomes south in the afternoon.
The main weather change arrives after midafternoon. The forecast calls for a chance of showers and thunderstorms between 3 p.m. and 5 p.m., then showers likely and possibly a thunderstorm after 5 p.m. The chance of precipitation is 60%.
That timing matters. Morning and early afternoon plans may get through with dry weather, although clouds will increase. Late afternoon and evening plans carry more risk.
This is the part of the forecast where it helps to stay flexible. A late-day shower may be short. A thunderstorm may bring a heavier downpour, gusty wind, and a quick change in visibility. New rainfall amounts during the day should generally stay under a tenth of an inch, except where thunderstorms produce heavier rain.
If Sunday includes youth sports, a picnic, a lake visit, or a drive along the Thruway corridor, keep an eye on the sky after lunch. Thunder can travel far, and storms can build quickly when warmer air and increasing moisture arrive.
Sunday night is the wettest period of the forecast. There is a chance of showers and thunderstorms before 8 p.m., then showers and possibly a thunderstorm between 8 p.m. and 11 p.m. After 11 p.m., showers continue. The chance of precipitation rises to 90%.
The low stays mild, around 65. South wind at 5 to 9 mph becomes light after midnight. Rainfall amounts are expected to range from a tenth to a quarter of an inch, with higher amounts possible in thunderstorms.
That mild low tells part of the story. A warmer, more humid night often helps sustain showers. It may also feel muggy compared with tonight’s clearer and cooler conditions.
Plan for Sunday night
Bring cushions, tools, and light outdoor items inside before evening.
Check gutters and drains if leaves or debris have collected.
Give extra time for nighttime travel.
Keep a backup indoor plan for outdoor gatherings.
Monday and Tuesday offer a calmer break
Monday does not look completely dry, but it is less active than Sunday night. Expect partly sunny skies with a high near 80. There is a chance of showers, and thunderstorms are also possible after 2 p.m. The chance of precipitation is 30%.
Winds start light from the west, then become northwest at 5 to 9 mph during the afternoon. That shift should help move the pattern along and may bring a fresher feel after Sunday night’s damp weather.
Monday’s shower chance looks scattered rather than widespread. That means some areas may see a brief shower while others stay dry. For outdoor plans, Monday is not a guaranteed rainout. It is a day to keep a radar check handy and avoid leaving weather-sensitive items outside for long.
Monday night turns partly cloudy with a low around 58. That sets up a better Tuesday.
Tuesday is one of the best days in the 7 day weather outlook. Sunshine returns, the high reaches near 80, and the night stays mostly clear with a low around 58. It is the kind of day that works well for errands, field work, outdoor appointments, and anything that needs a dry stretch.
After the Sunday night rain and Monday’s lingering shower chance, Tuesday should feel like a reset. Lawns and gardens may still be damp early, but sunshine should help improve conditions through the day.
If there is one day next week to prioritize outdoor work, Tuesday is the safest choice.
Midweek brings another shower window
Wednesday starts mostly sunny and warmer, with a high near 83. That makes it the warmest day in this forecast period. The next chance of showers arrives after 2 p.m., with a 40% chance of precipitation.
This does not mean rain all day. The better chance comes later, after daytime heating has had time to build clouds. If Wednesday includes plans outside, the morning into early afternoon may be the more favorable window.
Wednesday night looks more unsettled. Showers are likely, mainly between 8 p.m. and 2 a.m. Skies turn mostly cloudy, and the low settles around 62. The chance of precipitation is 60%.
That timing could affect evening activities, late practices, road trips, and anyone who prefers to finish yardwork after dinner. It may be better to handle those tasks earlier in the day if possible.
By Thursday, the forecast keeps a chance of showers, but the coverage looks lower. Expect partly sunny skies, a high near 78, and a 30% chance of precipitation. Thursday night turns partly cloudy with a low around 55.
Friday looks like a pleasant finish. Skies turn mostly sunny, and the high reaches near 76. That is cooler than the early-week highs but still comfortable for September-like outdoor plans, depending on the season and local conditions.
What to watch through the week
The forecast has several quiet stretches, but two periods stand out for planning: Sunday evening into Sunday night and Wednesday night.
Sunday night has the highest rain chance at 90%. If thunderstorms develop, rainfall could be heavier in spots than the general forecast amounts suggest. That is common with thunderstorm activity. One neighborhood may get a quick downpour while another gets lighter rain.
Wednesday night is the second main period to watch, with showers likely mainly between 8 p.m. and 2 a.m. While it does not look as wet as Sunday night from the information given, it is still enough to affect evening plans.
Fog is another smaller but practical concern today before 8 a.m. Calm wind, moisture near the ground, and cool early temperatures can all support patchy fog. Once the sun gets higher, visibility should improve.
Here is the simple planning breakdown:
Best window | Why it stands out |
Today after 8 a.m. | Fog lifts, mostly sunny skies take over, and winds stay light |
Tonight | Mostly clear and calm, with a cool low near 55 |
Tuesday | Sunny, mild, and one of the driest days in the outlook |
Friday | Mostly sunny, cooler, and comfortable |
Wetter window | What to expect |
Sunday after 3 p.m. | Showers and thunderstorms become more likely late |
Sunday night | Highest rain chance, with showers and possible storms |
Monday afternoon | Scattered showers or storms possible after 2 p.m. |
Wednesday night | Showers likely, mainly from evening into the early overnight |
A practical plan for the next seven days
This is a useful week for matching tasks to the weather.
Today is the day to take advantage of sunshine after the early fog clears. If outdoor chores have piled up, get them done before the pattern turns unsettled. Tonight is quiet, clear, and cool enough for comfortable sleeping weather in many homes.
Sunday should be treated as a two-part day. The first half has a better chance to stay dry. The second half turns more uncertain, especially after 3 p.m. By evening, showers and thunderstorms become more likely. Plan as if outdoor events may need shelter or a delay.
Monday is a transition day. It may not rain everywhere, but a shower or afternoon thunderstorm is possible. Tuesday looks much cleaner and more dependable.
Wednesday brings warmth and a late-day shower chance, then a wetter setup Wednesday night. Thursday keeps a lower shower chance before Friday brings a mostly sunny and slightly cooler finish.
The week’s main message is clear: enjoy the sunny start, stay weather-aware late Sunday, and save the most weather-sensitive plans for Tuesday or Friday when possible. Central New York gets several good breaks, but the stormy stretches deserve respect.
