Cold temps expected for trick-or-treaters in DC

As trick-or-treaters prepare for Halloween in the D.C. area, they should plan to cover up their costumes to stay warm because Tuesday will be chilly. Here’s what you need to know.

According to 7News First Alert Meteorologist Brian van de Graaff, daytime temperatures on Tuesday will be in the low to mid-50s, dry and chilly, but will fall into the 40s when its time to add candy to your Halloween bucket.

“It’s going to be a cold one; a big shock to the system,” van de Graaff said.

There will be a mix of sun and clouds Tuesday.

Some frost and freeze could occur overnight into Wednesday, with temperatures in the 30s possible.

As November begins on Wednesday, van de Graaff said expect the coldest day of the week with temperatures struggling to make the low 50s and winds reaching 25 mph.

A freeze watch is in effect for the region from 2 a.m. to 10 a.m. Thursday. Any cold temperature sensitive plants and flowers should be brought indoors or protected.

The D.C. area won’t be the only ones affected by the drop in temperatures. The cold air coming from Canada will bring colder temperatures throughout most of the country — except for the West Coast. The shifting weather patterns nationwide also affected pumpkins this year as the summer’s record-breaking heat caused watering issues for farmers.

Hot, humid week ahead for DC area with severe storm risk

A dangerous heat wave will grip the D.C. area through Thursday, with highs in the mid to upper 90s and heat index values between 100 and 105. Hot and humid conditions are expected through Thursday, according to the National Weather Service, which said to expect daily thunderstorm chances and a risk of severe thunderstorms. 7News Meteorologist Eileen Whelan told WTOP that most of Tuesday will stay dry, but a few late-day thunderstorms are possible, especially north and east of D.C. as storms drift south from Pennsylvania. Any storm could produce damaging wind gusts and hail, but Whelan reiterated "storm chances are low" on Tuesday. Due to a lack of air conditioning, Parkdale High School in Riverdale, Maryland, closed early at 10:30 a.m. on Tuesday, Prince George's County Public Schools said in a social media post.
