Maryland Heatwave: Record Highs Loom This Week
13 Apr
Summary
- Record high temperatures are forecast for Wednesday and Thursday.
- Hot weather, low humidity, and drought fuel high fire danger.
- Summer-like temperatures in the 80s and 90s expected all week.
Unseasonably hot weather is expected to build across Maryland this week, with record high temperatures potentially occurring on Wednesday and Thursday. Although humidity will be low, the persistent heat, coupled with worsening drought conditions and low relative humidity, will create high fire danger.
Temperatures will start in the 70s on Monday, climbing into the upper 80s on Tuesday, with many areas experiencing mild mornings. By Wednesday and Thursday, temperatures could significantly surpass historical records. For example, the record high at BWI Marshall for Wednesday is 88° set in 1941, but a high of 92° is forecast, which would break it.
The dry and hot conditions will lead to an increased risk of brush fires from Tuesday through Friday, with relative humidity dropping into the 20% to 30% range during afternoons. Residents are urged to exercise extreme caution and be aware of potential burn bans.
Summer-like temperatures in the mid to upper 80s are expected to continue through Friday and Saturday. A cold front approaching on Friday might bring isolated showers, particularly north and west of Baltimore. A stronger front on Sunday is predicted to end the heatwave, bringing cooler temperatures and much-needed rain.
