Extreme heat wave coming to Maryland this week
Wednesday through Saturday are First Alert Weather Days due to impacts from dangerous heat. In addition to the heat, the First Alert Weather team will be tracking the potential for strong thunderstorms late this week into the holiday weekend.
Warm again across Maryland Tuesday
After day with near-normal temperatures on Monday, Tuesday is expected to be slightly warmer. Highs warm into the upper 80s to low 90s.
Humidity remains in place overnight into Tuesday, as temperatures fall into the 60s to low 70s overnight.
It's not until midweek that we feel the real spike in temperature.
Near-record heat is in Baltimore's forecast
A heat wave is set to impact much of the Mid-Atlantic and surrounding areas starting in the middle of the week. Afternoon high temperatures spike into the upper 90s and lower 100s for multiple afternoons, beginning on Wednesday.
Humidity stays elevated through this week - both during the daytime and overnight hours. Once humidity is factored in, it will feel hotter than 105° for many neighborhoods and for some, it may feel like it's 110° (or even slightly warmer) during the warmest part of the day. It's that combination of heat and humidity that prompted the First Alert Weather team to issue First Alert Weather Days starting Wednesday into the Fourth of July holiday on Saturday.
Overnight temperatures remain warm, as well.. It may fail to cool below the upper 70s - and even low 80s - a few nights this week. Use extra caution if working outside and check on those without adequate ways of cooling off. It will remain especially warm overnight in Baltimore City and other areas with lots of concrete. Prepare now before dangerous heat moves in.
Along with the heat, isolated thunderstorm chances will return a little later in the week. The best chance for severe storms looks like Friday into early next week. Severe wind gusts are possible with any storms that manage to develop. The heat will ease slightly following July 4th. Forecast highs will go from the triple digits to mid-90s. You'll still need to practice heat safety precautions into next week, as well.
