Near Record Heat Through Saturday

WASHINGTON (WUSA) - This first full week of September has featured a late summer heat wave. Looking ahead, a couple of records will be in jeopardy for the next several days.

For this Thursday, with temperatures expected to top out between 93° and 97°, the record high at Dulles International Airport and in Martinsburg will be in jeopardy. The record of 93 at Dulles is a young daily record, set just last summer. The record in Washington should be safe at 100°, as in Baltimore. Part of the reason why the records in Washington and at Baltimore are considerably higher than at Dulles is because of the much longer time span of weather data available for those two locations.

 

It is impressive that highs today will be near records. Factoring in the humidity, triple digit feels-like temperatures are expected area-wide. The heat index will top out 100-105 this afternoon.


Temperatures Friday and Saturday will also be unseasonably warm. The records daily highs for Friday are once again very close to the forecast highs for the day.

 

90-degree heat in September is not unheard of in Washington. Especially in the last decade, there has often been a stretch of early-month heat, despite the average highs falling through the mid and low 80s. Last year in 2015, 7 out of the first 10 days of the month featured high temperatures in the 90s. 
 
It looks like this current heat wave will break by Sunday....as highs then will fall back into the low to mid 80s.
