What happened

Majority of US to experience severe heat, storms and dreary conditions thanks to omega weather pattern Millions of Americans are bracing for a wave of stagnant weather this week with the potential for soaring temperatures and severe storms across the country.

Why it matters

An Omega block weather pattern is starting to take hold across the US, leaving various regions under the same conditions all week long.

Common ground

Omega block weather patterns get their name because the upper air pattern looks like the Greek letter omega (Ω).
