Tulsa, Oklahoma, is experiencing a shift in weather patterns this Saturday, April 25, 2026. Residents can expect a transition from overcast skies to potential storm activity as a low-pressure system moves through the region. Today's forecast indicates a high temperature of 75°F (24°C) and a low of 60°F (16°C), with humidity levels reaching 80%. The primary concern for the day involves scattered thunderstorms, particularly during the late afternoon and evening hours.

Current Conditions and Immediate Outlook for Saturday

The morning in Tulsa begins with significant cloud cover and high humidity. As the day progresses, the atmosphere is expected to become increasingly unstable.

Temperature and Precipitation Probability

The daytime high is projected to settle near 75°F, staying relatively consistent with the previous day's trends. However, the probability of rain is structured as follows:

  • Daytime: 35% chance of scattered showers and thunderstorms.
  • Nighttime: The probability increases to 40%, with some models suggesting up to 60-80% likelihood of localized heavy rain between 7:00 PM and 10:00 PM.

Wind and Atmospheric Pressure

Winds are currently originating from the southeast at approximately 10 to 15 mph, with occasional gusts reaching up to 20-25 mph. The barometric pressure remains around 29.80 inches, indicating a typical spring weather disturbance for Northeast Oklahoma.

Severe Weather Potential in Northeast Oklahoma

While the general forecast mentions thunderstorms, specialized meteorological data suggests that some of these storms could become severe. For a city located in the heart of "Tornado Alley," spring storms require careful monitoring.

Potential Hazards

Meteorologists are tracking a cold front that may interact with the warm, moist air currently sitting over the Tulsa metro area. This interaction could lead to:

  1. Damaging Winds: Gusts exceeding 40 mph are possible within organized storm cells.
  2. Large Hail: The vertical structure of the expected storms suggests a risk of hail, which is a common occurrence in Oklahoma during late April.
  3. Localized Flooding: With humidity at 81% and a dew point of 59°F, the atmosphere is primed for heavy downpours. New rainfall amounts between a quarter and half of an inch are possible by Sunday morning.

Timing the Storms

The most critical window for severe weather appears to be after 4:00 PM on Saturday. Residents planning outdoor activities at the Gathering Place or near the Arkansas River should have a way to receive weather alerts and be prepared to move indoors if sirens are activated.

Extended Forecast for Sunday and Early Next Week

Following the passage of the Saturday night storm system, Tulsa will see a gradual stabilization of the weather, followed by a significant warming trend.

Sunday, April 26: The Transition Day

Sunday will maintain a linger of cloudiness, especially in the early morning.

  • High: 77°F (25°C) to 80°F (27°C).
  • Low: 69°F (21°C).
  • Conditions: Mostly cloudy with a 30% chance of showers, mainly after 1:00 PM. Southeast winds will persist, gusting up to 25 mph. By midnight, skies are expected to clear, setting the stage for a brighter Monday.

Monday, April 27: A Return to Sunshine

Monday marks a definitive shift toward early summer conditions. The region will experience a "thermal ridge" that pushes temperatures well above the seasonal average.

  • High: 87°F (31°C).
  • Low: 53°F (12°C).
  • Conditions: Exceptionally sunny and clear. Winds will shift from southerly to westerly in the afternoon, providing a drier heat compared to the humid weekend.

Tuesday, April 28 through Thursday

The mid-week forecast shows a slight cooling trend as a weak northerly breeze enters the area.

  • Tuesday: Mostly sunny with a high of 76°F. There is a slight (20%) chance of showers late in the evening.
  • Wednesday: Mostly sunny and pleasant with a high near 73°F.
  • Thursday: Increased cloud cover returns, with a 40% chance of rain and a high of 70°F.

Understanding Tulsa's April Climate Patterns

To put the current forecast for April 25 into perspective, one must understand the unique climatology of Tulsa. April is historically one of the wettest and most volatile months for the city.

Average Temperatures and Extremes

Typically, Tulsa sees average highs in the low 70s during late April. Today's forecast of 75°F is slightly above the norm, while Monday's projected 87°F is significantly higher, approaching record levels for the date.

Rainfall and Storm Frequency

The city receives an average of 4.3 inches of rain throughout April. The current pattern of scattered thunderstorms followed by rapid clearing is a hallmark of the Great Plains' dryline movements. When dry air from the West meets moist air from the Gulf of Mexico, the resulting "collision" often happens right over Tulsa County, leading to the rapid development of cumulonimbus clouds.

Preparing for Spring Weather in Tulsa

Given the 40-80% chance of thunderstorms tonight, it is essential for residents to review basic safety protocols.

Home and Property Safety

  • Secure Loose Items: With gusts up to 25 mph expected, patio furniture and trash bins should be secured.
  • Check Drainage: Ensure gutters and downspouts are clear to handle the projected half-inch of rain.
  • Garage Vehicles: If the forecast upgrades to a "Severe Thunderstorm Warning" involving hail, moving vehicles under cover is highly recommended.

Transportation and Travel

Driving conditions on Highway 169 and I-44 may become hazardous during the Saturday evening commute if heavy rain reduces visibility. Hydroplaning is a major risk on Oklahoma roads during the first few minutes of a storm when oil and water mix on the asphalt.

Summary of the Weekly Outlook

The upcoming week in Tulsa is characterized by a "sandwich" of storm activity. We begin with a humid, storm-prone weekend, move into a very warm and sunny Monday, and return to cooler, showery conditions by the end of the week.

  • Saturday (Today): Cloudy, humid, and stormy. High 75°F.
  • Sunday: Lingering clouds, minor rain chance. High 80°F.
  • Monday: Sunny and hot. High 87°F.
  • Mid-Week: Mild and sunny. Highs in the mid-70s.

FAQ: Tulsa Weather Questions

What time will it start raining in Tulsa today?

Based on the latest radar projections, the highest probability of rain begins after 4:00 PM, with the most intense thunderstorm activity likely occurring between 7:00 PM and 10:00 PM.

Is there a tornado threat for April 25, 2026?

While the current forecast emphasizes "damaging winds and large hail," any severe thunderstorm in Oklahoma during April requires monitoring for rotation. Residents should stay tuned to local sirens and weather apps for real-time updates.

Will Sunday be a good day for outdoor activities?

Sunday morning will be cloudy, but the overall rain chance is lower (30%) compared to Saturday night. The afternoon should be manageable for outdoor plans, though it will be breezy with gusts up to 25 mph.

Why is it getting so hot on Monday?

Monday's high of 87°F is caused by a strong southerly wind bringing warm air from the Gulf and a compression of air masses ahead of the next minor front. This is common before the weather settles back into the 70s later in the week.

What is the humidity level today?

Humidity is expected to remain high at approximately 80% to 81%, contributing to a "muggy" feel before the thunderstorms arrive to cool the air.
