Stifling heat just isn’t letting up in the D.C. region, as feels-like temperatures are expected to approach and even pass 105 degrees Wednesday afternoon, making it the third straight day the area has dealt with triple-digit heat index values.
The National Weather Service has issued yet another heat advisory covering the entire D.C. area that’s in effect from noon to 8 p.m. Wednesday. According to the weather service, the expected heat index values are up to 110 degrees in some areas.
Even stepping out of the door Wednesday morning, it’s going to feel hot, according to 7News First Alert Chief Meteorologist Veronica Johnson. The lowest temperature of the day Wednesday could flirt with a record.
“The all-time high low temperature for the area is 84 degrees and here I’m forecasting 81. Factor in the humidity, even for (Wednesday) morning, and that will take that temperature and make it feel like 91 in the morning. It is going to be quite warm and very humid even to start the day. Temperatures will rise quickly,” Johnson said.
Wednesday evening will also carry the risk of storms as a brewing system links up with some of the remnants of what was Hurricane Beryl.
“The moisture from Beryl, we haven’t stopped tracking that. That will pass through the Ohio Valley on north and yes, some of that spin will be interacting with our weather-maker near, so we’ve got some storms potentially between 6 p.m. now and just past midnight. Any storms could produce some downpours, maybe some urban flooding and even some damaging winds, there’s that threat,” Johnson said.
Thursday doesn’t bring much relief from the heat, with temperatures between 90 and 95 degrees, with feels-like temperatures even higher. But things will finally cool down for the end of the week, with forecast highs only between 80 and 85 degrees Friday, with another chance of storms.
WEDNESDAY: HEAT ADVISORY Noon-8 P.M.
Partly sunny, scattered storms at night
Highs: 93-98
Heat Index: 105-109
Winds: South 10-15, Gusts to 25 mph
Plan for yet another very hot and very humid day with feels-like temperatures back over 105 during the afternoon. A heat advisory has been posted for most of the DMV beginning at noon and extending until 8 p.m. The remnants of Beryl will be moving over the Great Lakes late in the day and will provide the risk for rain and storms by this evening. The greatest risk for severe weather will be well north of the 7News viewing area; however, a few storms may contain damaging wind gusts. Frequent thunder and lightning is also likely with such high humidity.
WEDNESDAY NIGHT:
Rain ending, turning partly cloudy
Lows: 68-75
Winds: Southwest to Northwest 5-10 mph
Rain chances taper off after midnight with skies becoming partly cloudy by dawn. Areas of patchy fog are possible.
THURSDAY:
Partly sunny, isolated shower, storm
Highs: 88-94
Winds: Southwest 5-10 mph
It won’t be quite as hot Thursday with highs, closer to average, in the low 90s. Humidity levels will also drop off a bit (dew points in the upper 60s), so heat index values will range from 95-98 during the afternoon. A stray storm is possible, but most will stay dry.
FRIDAY:
Mostly cloudy, scattered showers, storms
Highs: 82-86
Winds: Southeast 5-10 mph
We’ll round out the week with cooler highs in the lows 80s, but with increasing humidity, feels-like temperatures will be in the mid-80s. A stalled weather boundary to our east will provide us with clouds and rain chances. Pockets of heavy rain could lead to isolated flooding.
THIS WEEKEND:
High temperatures climb back into the 90s for the upcoming weekend with feels-like temperatures in the upper 90s Saturday and possibly over 100 on Sunday.
