If you've been wondering why the skies over Onondaga County have been persistently gray and rainy lately, the answer lies in a meteorological phenomenon known as an "Omega Block." This unusual weather pattern has been responsible for the extended periods of precipitation we've experienced in early May.

What Is an Omega Block?

An Omega Block is a large-scale weather pattern characterized by a high-pressure system sandwiched between two low-pressure systems, forming a shape that resembles the Greek letter Omega (Ω) on weather maps. This configuration disrupts the typical west-to-east movement of weather systems, causing them to stall and leading to prolonged weather conditions in affected areas.

In our current situation, a cutoff low-pressure system has become trapped over the Tennessee and Ohio valleys, drawing moisture from the Atlantic Ocean and funneling it into the Northeast, including Central New York. This has resulted in multiple rounds of rain and thunderstorms, with rainfall totals potentially reaching 3 to 5 inches in some areas.

Impacts on Onondaga County

The persistent rainfall has raised concerns about localized flooding, particularly in urban areas with poor drainage. While widespread severe flooding is not expected, residents should remain vigilant and prepared for potential flash floods in low-lying areas.

Additionally, the saturated ground conditions can pose challenges for homeowners, such as water seepage into basements and delays in outdoor projects. It's essential to ensure that gutters and drainage systems are functioning correctly to mitigate water-related issues.

Looking Ahead

Meteorologists anticipate that the Omega Block pattern will persist for several more days, maintaining the unsettled weather in our region. However, a shift in the jet stream is expected to eventually break the pattern, allowing for a return to more typical spring weather conditions.

Tips for Homeowners

• Stay Informed: Keep an eye on local weather forecasts and alerts to stay updated on changing conditions.

• Protect Your Property: Make sure your sump pump is working properly and consider running a dehumidifier in damp areas like the basement. Watch for pooling water around your yard or foundation, and check that gutters and downspouts are clear and directing water away from your home.

• Delay Outdoor Projects: Postpone any landscaping or exterior work until the ground has had time to dry out to prevent damage.
