Unseasonably hot weather is expected to build into Maryland this week, with record high temperatures possible on Wednesday and Thursday. Temperatures could reach the upper 80s and low 90s, shattering previous records. The hot, dry conditions will also increase the risk of brush fires across the state.

Why it matters

Extreme heat in April is highly unusual for Maryland and could have significant impacts, including increased risk of wildfires, strain on the power grid, and health risks for vulnerable populations. This heat wave is a concerning sign of the effects of climate change on regional weather patterns.

The details

Temperatures are forecast to climb well above average, with highs potentially reaching the low to mid 90s on Wednesday and Thursday. This would break previous record highs of 88°F on April 15 and 90°F on April 16. The hot, dry conditions will also lead to an elevated risk of brush fires, with relative humidity levels dropping to 20-30% in the afternoons. Residents are being warned to avoid burning and be extremely cautious with any potential ignition sources.

  • Temperatures will start to climb on Monday, with many areas seeing morning lows in the 50s and 60s and highs reaching the upper 70s and low 80s.
  • Tuesday will be even hotter, with morning lows in the low to mid 60s and afternoon highs in the upper 80s.
  • Record highs are possible on both Wednesday and Thursday, with forecasts calling for highs of 92°F and 91°F respectively.
  • The heat wave is expected to continue through Friday and Saturday, with highs in the mid to upper 80s.
  • A cold front is expected to move through on Sunday, bringing an end to the unseasonable warmth and a chance of showers and thunderstorms.
