Baltimore’s first 90-degree day of the year comes around May 12, on average, according to weather service data. It hasn’t arrived later than May 20 since 2016, when it did not reach the 90s at BWI until May 26.
There aren’t many days left this month with chances to break the barrier again. Spring weather is forecast to return Tuesday.
High temperatures are forecast in the 70s and lower 80s around Baltimore from Tuesday through the Memorial Day weekend, leaving just a few days at the end of the month with a chance for heat to return. It should provide some relief for Baltimore City schools, which dismissed students from Monarch Academy and Baltimore Leadership School for Young Women early Monday due to air conditioning problems.
The Climate Prediction Center forecasts hotter-than-normal temperatures to dominate the eastern U.S. at the end of the month and into early June.
