Calm start before a prolonged wet pattern

Central New York, United States begins the week on a quieter note.

Monday stays mostly dry, with temperatures rising into the mid 60s. The air feels mild. Stable, for now.

That changes overnight.

A warm front moves in and slows down. It stalls across the region. The atmosphere shifts.

Rain begins Monday night. It does not leave quickly.

Stalled front brings steady rain and rising flood risk

The front lingers from Monday night into Tuesday. It holds its position.

Widespread showers develop, becoming heavy at times. Rain falls steadily, then intensifies. Then eases. Then returns.

Forecast guidance highlights rainfall rates of 1 to 2 inches within six hours. Enough to overwhelm drainage systems. Enough to trigger flash flooding in vulnerable areas.

The ground begins to saturate.

Warmer air builds, but conditions vary across the region

Tuesday brings warmer air into Central New York, United States. Temperatures climb into the upper 60s.

But the warmth is uneven.

Areas near Lake Ontario, NY, United States remain cooler, held back by the position of the stalled front. Just a short distance makes a difference.

Scattered showers and thunderstorms continue through the day. The heaviest rainfall is expected Tuesday night.

Rain returns in waves.

Multiple systems reinforce the wet pattern

This is not a single storm.

Several weather systems track across the Great Lakes region, one after another. A stationary front drifts slowly across Central New York, United States from Tuesday into Wednesday, then lifts north again as a warm front by Thursday.

Each shift brings more precipitation.

Each system adds more water.

Total rainfall through the weekend may reach several inches. The exact placement of the heaviest bands remains uncertain, but the risk increases with time as soils become saturated.

Brief break possible before more rain arrives

Wednesday may offer a short pause.

As a cold front pushes south of the region, rain could ease during the afternoon and evening. The break may be temporary.

If the front stalls closer than expected, showers could return sooner.

The pattern remains unsettled.

Temperatures swing as fronts shift position

Temperatures fluctuate throughout the week, tied closely to the movement of frontal boundaries.

On the cooler side, readings fall into the 40s. On the warmer side, they rise into the 60s and even 70s.

The contrast is sharp. The change can happen within hours.

Moisture feed sustains rain into the weekend

A strong high-pressure system over the western Atlantic blocks weather systems from moving out to sea. Instead, they track repeatedly across the Great Lakes.

Moisture continues to flow north from the Gulf.

The supply does not cut off.

Rain persists into the weekend. The ground remains saturated. Water levels respond.

Preparedness urged as conditions evolve

Forecasters highlight the potential for localized flooding, particularly in low-lying areas, near small streams, and in locations with poor drainage.

Residents are advised to monitor updates closely as timing and intensity of rainfall may shift.

The pattern is active. The risk builds.
