After a string of pleasant days, including highs in the upper 60s today (Monday, October 17), temperatures are expected to take a bit of a nosedive mid-week with high expected to be in the mid to upper 50s.

Monday is expected to reach 67° with clouds and a slight chance of rain. Tuesday will get to about 55° with a breeze that’ll make it feel even cooler and more like November . Wednesday will be about the same as Tuesday without the breeze, but will still feel cool with highs around 56°. Thursday will be mostly sunny with temperatures getting up to about 59°. Friday looks to be pleasant with sunny skies and temps in the mid 60s. As of now, the weekend is also looking nice with sunny skies and temperatures around 70° on Saturday and mid 60s on Sunday.

Summer officially comes to an end as the autumnal, fall, or September equinox arrives at 9:04pm Thursday night. This makes the official start of fall in the Northern Hemisphere and Mother Nature is complying as highs are expected to be in the mid-60s in our area on Friday.

We’ve had a couple chillier mornings lately and highs today reached the mid 70s, but Friday is expected to remain below 70 all day. Overnight temperatures into Friday morning are expected to drop into the 50s and feel like the low 40s. Mostly sunny skies are expected, which will make the cooler day feel not-so-bad.

There’s a flood warning in effect for parts of Montgomery County until 11:30am Tuesday morning. Flooding caused by excessive rainfall is expected in portions of central Maryland and north central Maryland, including the following counties: in central Maryland, Howard and Montgomery.

Between 1.5 and 3 inches of rain have fallen. Additional rainfall amounts of 0.5 to 1.5 inches are possible in the warned area. Some locations that will experience flooding include, Germantown, Frederick, Rockville, Gaithersburg, Leesburg, Olney, Westminster, Damascus, Lowes Island, Poolesville, Aspen Hill, Potomac, North Bethesda, Montgomery Village, North Potomac, Ballenger Creek, Redland, Great Falls, Mount Airy, and Walkersville.

Coming off of the hottest day of the year, we are experiencing another hot one as the July heat wave ends. Temperatures should reach approximately 90 degrees for most later on Monday afternoon before a cold front brings the chance of sever weather in the form of thunderstorms later this evening. According to the National Weather Service, “A cold front will push through the region today bringing showers and thunderstorms to the region. A few storms may become severe, bringing damaging wind gusts and heavy rainfall.”

As the day goes on, chances of showers increase this evening, with the greater chance for thunderstorms coming this evening around 7pm and into the early night. Highs tomorrow will be in the low 80s, which will be a  welcomed break from the 90+ degree weather for many in the area. Temperatures are expected to remain pleasant and in the 80s for the rest of the week, including the weekend. August looks to be coming in warm, with temperatures approaching 90 degrees, but we are still about a week or so away.

There is a Heat Advisory in effect this from 11am Sunday morning until 8p on Sunday night as temperatures approach 100 degrees and heat index values between 100 and 107 degrees. Temperatures will get into the 80s before 11am will be in upper 90s this afternoon. The National Weather Service advises to stay cool and hydrated and remember to take plenty of breaks throughout the day today when doing outdoor activities. Monday will also bring temperatures in the 90s along with the change of heavy thunderstorms in the afternoon before the heat lets up on Tuesday.

Per the National Weather Service:

Heat stroke is an emergency! Call 9 1 1.

Temperatures this weekend are likely to be a couple degrees hotter than they’ve been the last couple degrees, pushing 100° on Saturday and Sunday. The Heat Index will be over 100° on both days. Montgomery County Fire and Rescue Services suggest to take frequent breaks in cool/shaded areas if you have to be outside.

Temperatures on Mondays are also likely to reach the mid 90s  with a chance of thunderstorms before the heat finally relents on Tuesday, barely reaching 80° Before getting into the upper 80s the rest of the week. Safety Tips by the National Weather Service can be seen below.

Hot and humid conditions are expected today, according to the National Weather Service. High temperatures will reach the mid to upper 90s today and the Heat Index will be around 100 degrees. Scattered showers and thunderstorms are possible the closer you get to Washington, D.C. this afternoon, but the biggest concern for strong to severe storm with damaging winds remains south of DC.

Friday is expected to be similar to today, with temperatures again reaching the mid 90s and feeling like its 100 degrees. The weekend will bring even hotter temps, with actual highs in the upper 90s and the heat index nearing 105 degrees. The state of Maryland sent out the following message yesterday:

There is a Flood Watch in effect this afternoon, Wednesday, June 22, for Northwest MoCo that will begin at 3pm through this evening. Today will start with plenty of us with temperatures reaching the upper 80s and feeling like the mid to upper 90s. Thunderstorms are expected to roll in during the late afternoon hours. Per the National Weather Service:

Montgomery County and some surrounding areas, primarily to the south and east, are at a ‘slight risk’ for severe weather throughout the day today (Tuesday, June 14th), according to the National Weather Service.

“There will be a few opportunities for showers and thunderstorms through this morning and early afternoon. The strongest storms could contain damaging wind gusts, hail, heavy rain, and frequent lightning.” The chance of rain and thunderstorms decreases as we move into the later afternoon and high temperatures reach the low 80s.

A mostly sunny day is expected today with temperatures reaching approximately 80° and feeling like it’s in the mid to upper 80s. There is also virtually no chance of rain today, which gives us a great start to the week.

The rest of the week will be similar in regards to temperature (highs in the low 80s), but rain is possible on Tuesday, Wednesday, and Thursday. Tuesday could become breezy in the afternoon with a 40% chance of a thunderstorm in spots. Wednesday gives us the greatest shot at rain with a 55% chance at thunderstorms in the afternoon. Thursday gives us a 40% chance at some morning showers.
