Sunny Start Followed by a Stormy Week Ahead

The week opens with the kind of weather that makes Central New York feel wide awake: sunshine, warmth, and a high near 83. That pleasant start will not hold for long. Clouds build tonight, showers return before daybreak, and several rounds of rain and thunderstorms are likely through early next week.
For Canastota and nearby parts of Madison County, the main theme is simple: enjoy the sunny start, then keep rain gear close. The forecast points to a wetter, more unsettled pattern from late tonight through Monday night, with another round of likely showers arriving late in the week.
Today brings the best outdoor window
Today is the easy part of the forecast. Skies stay sunny, and temperatures rise to a high near 83 degrees. Winds start from the east at 5 to 7 mph, then turn southerly during the afternoon.
That makes today the best day for outdoor plans before the pattern turns more active. Lawn work, a walk near the lake, errands, youth sports, grilling, or time on the porch all fit nicely into the daylight hours.
The air will feel warm, but the wind stays light. That matters for comfort. A light breeze from the south in the afternoon can make the warmth feel pleasant rather than heavy, especially in open areas around farm fields and neighborhoods east of Oneida Lake.
The key is not to let the sunshine hide what comes next. If there are loose items outside, today is a good time to secure them. Patio cushions, umbrellas, garden tools, and trash bins are easier to deal with before showers and storms move in.
A few practical moves for today:
Check gutters and downspouts before the rainier stretch.
Water-sensitive outdoor items should come inside by evening.
Charge devices if thunderstorms could affect power later.
Plan longer outdoor activities earlier rather than later.
This is not a washout day. It is the calm lead-in.
Tonight turns cloudy with showers and thunderstorms late
Tonight starts with only a slight chance of showers before 2 a.m. After that, the chance rises. Showers and thunderstorms become possible between 2 a.m. and 4 a.m., then showers become likely after 4 a.m., with a thunderstorm also possible.
Clouds increase through the night, and the low settles around 61 degrees. The southeast wind holds around 7 mph.
The chance of precipitation is 60 percent. Most rainfall amounts look light to moderate, generally between a tenth and a quarter of an inch. Thunderstorms could bring higher amounts in spots.
That last part matters. A forecast can call for a tenth to a quarter of an inch overall, while a thunderstorm still drops heavier rain over one neighborhood and very little over another. Convective rain is uneven by nature. One side of town may see a quick downpour while another gets a brief shower.
For overnight planning, the main concerns are:
Wet roads before the Sunday morning drive.
Rumbles of thunder during the pre-dawn hours.
Heavier bursts of rain in any stronger storm.
Lower visibility where showers arrive before sunrise.
If windows are open during the warm evening, plan to close them before bed. The weather shifts after midnight, and the daybreak period looks much wetter than the start of the night.
Sunday looks wet, especially before midafternoon
Sunday brings the most widespread rain risk of the weekend. Showers and thunderstorms are expected before 3 p.m. Then showers remain likely, with a thunderstorm possible between 3 p.m. and 4 p.m. After 4 p.m., scattered showers and thunderstorms remain possible.
The high reaches near 77 degrees, cooler than today but still mild. Winds come from the southeast at 6 to 8 mph, then shift west in the afternoon. That wind shift often marks a change in the air mass as the system moves through.
The chance of precipitation is 80 percent, so it is fair to treat Sunday as a wet day. Rainfall totals again look mostly between a tenth and a quarter of an inch, with higher amounts possible in thunderstorms.
Sunday will not necessarily rain every minute. The forecast points to waves of showers and storms rather than one perfectly steady rain from sunrise to sunset. Still, the odds favor needing an umbrella, rain jacket, or backup indoor plan.
This is the day to watch if there are:
Outdoor services or community events.
Baseball, softball, soccer, or other field sports.
Yard projects that need dry time.
Longer drives on local roads or the Thruway.
Plans near low spots that collect water quickly.
Thunderstorms before 3 p.m. could disrupt morning and early afternoon activities. If thunder is heard, move indoors. Lightning can strike away from the heaviest rain, and open fields, ball diamonds, lakeshores, and parking lots offer little protection.
The good news is that temperatures stay manageable. This does not look like a cold rain. It will feel damp and unsettled, with a mild high in the upper 70s.
Sunday night calms down somewhat, but it does not turn fully dry right away. A slight chance of showers and thunderstorms lingers, then a chance of showers continues after 8 p.m. Skies turn partly cloudy, and the low drops to around 53 degrees. The chance of precipitation falls to 30 percent.
New rainfall Sunday night should stay under a tenth of an inch for most areas, except where a thunderstorm manages to linger.
Monday may be the stormiest stretch
Monday keeps the unsettled pattern going and could be the most active day of the early week. The day starts with a chance of showers, then showers and possibly a thunderstorm become likely after 2 p.m.
The high reaches near 71 degrees, making Monday cooler than the weekend. Southwest winds run 6 to 10 mph. The chance of precipitation rises to 90 percent, which is the highest probability in this forecast period.
That high rain chance sends a clear signal: plan for wet weather on Monday. Even if the morning offers some breaks, the afternoon looks more likely to bring showers and a possible thunderstorm.
Monday night stays active. Showers and thunderstorms are expected before 11 p.m., followed by a chance of showers overnight. The low settles near 52 degrees, with an 80 percent chance of precipitation.
For commuters, school schedules, and evening errands, Monday may require extra patience. Wet pavement, ponding in poor drainage spots, and quick changes in visibility can slow travel. In Central New York, heavier rain can also collect along rural shoulders and in dips on secondary roads. Those spots are easy to underestimate after dark.
Here is the early-week setup at a glance:
Period | Main weather | High or low | Rain chance |
Today | Sunny | High near 83 | Low |
Tonight | Showers and storms late | Low around 61 | 60% |
Sunday | Showers and thunderstorms | High near 77 | 80% |
Sunday night | Partly cloudy with some showers | Low around 53 | 30% |
Monday | Showers, possible thunderstorm after 2 p.m. | High near 71 | 90% |
Monday night | Showers and thunderstorms before 11 p.m. | Low around 52 | 80% |
The table shows the biggest change well. The weekend starts bright and warm, then the pattern flips toward repeated rain chances. Monday stands out because the precipitation chance stays high during both the day and evening.
Tuesday offers a partial break before warmer weather returns
Tuesday is not perfectly dry, but it looks less active than Sunday and Monday. A chance of showers returns after 8 a.m. Skies run partly sunny, and the high climbs to around 74 degrees. The chance of precipitation is 40 percent.
That means Tuesday may bring a few showers rather than a true all-day soaking. It could be a better day for errands, outdoor chores, or travel, as long as plans can handle a passing shower.
Tuesday night turns partly cloudy with a low around 53 degrees. That offers a more comfortable and quieter night after the wetter start to the week.
Wednesday brings the best midweek improvement. Skies turn mostly sunny, and temperatures climb to a high near 80 degrees. Wednesday night stays partly cloudy, with a low around 58 degrees.
For anyone trying to find a dry window after the rain, Wednesday looks like the best bet. It may be the right time to mow, dry out sports fields, clean up after showers, or get outside without watching the radar every few minutes.
The midweek warmth will also help surfaces dry, especially if rain amounts stay modest. Still, shaded yards and heavier soil may remain damp after rounds of showers. Give saturated spots time before driving equipment or heavy carts across them.
Late week brings another round of likely showers
The dry break does not last long. Thursday turns unsettled again, with showers likely and partly sunny skies. The high reaches near 83 degrees, so the air turns warm even as rain chances rise. The chance of precipitation is 60 percent.
Thursday night remains mostly cloudy with showers likely. The low stays mild, around 61 degrees, and the rain chance holds at 60 percent.
Friday continues the same general pattern. Showers remain likely, skies stay partly sunny, and the high reaches near 81 degrees. The chance of precipitation stays at 60 percent.
This late-week stretch looks different from a chilly, gray rain pattern. Temperatures rebound into the lower 80s, which can help fuel showers if enough moisture and lift are present. The forecast does not guarantee thunder for Thursday and Friday in the same way it highlights thunderstorms earlier in the period, but showers look likely.
For planning purposes, late week is not a lock for dry outdoor work. It may still offer usable breaks, yet the risk of showers stays high enough to keep flexible plans in place.
If the week includes gardening, construction work, deliveries, field prep, or lake plans, Wednesday is currently the cleanest window. Thursday and Friday need more caution.
What this forecast means for the week
This forecast has three clear phases.
Today brings sunshine and warmth. It is the standout day for dry outdoor plans, with a high near 83 and light winds.
Tonight through Monday night brings the wettest and stormiest stretch. Showers and thunderstorms become likely late tonight, continue through much of Sunday, and return with high confidence Monday into Monday night. Rain totals may stay modest for many locations, but thunderstorms can create locally heavier amounts.
Tuesday and Wednesday bring improvement. Tuesday still carries a shower chance, but Wednesday looks mostly sunny and warmer, with highs near 80.
Then Thursday and Friday bring another unsettled period, with showers likely both days and highs in the lower 80s.
For Central New York, this is a classic changeable stretch. A dry and sunny start gives way to several rounds of showers, with enough breaks to get things done if plans stay flexible.
The best approach is simple:
Use today for outdoor work and longer dry-weather plans.
Expect wet roads and possible thunder late tonight and Sunday.
Treat Monday as the highest-impact rain day.
Look to Wednesday for the best midweek break.
Keep rain gear ready again Thursday and Friday.
The week will not be a total washout, but it will reward anyone who checks the forecast before heading out. Sunshine opens the door today. After that, the umbrella earns its keep.
