The Farmers’ Almanac has released its 2022-2023 extended winter outlook. MoCo and almost all of Maryland seem to fall under the “Significant Shivers, Slushy, Icy, Snowy” category. Just to our south and west is the “Unreasonably Cold, Snowy” category, which means that we may have a good amount of winter precipitation for the first time in a few years, according to the forecast.

“The Farmers’ Almanac suggests a stormy winter in on schedule especially for the eastern half of the country. For some areas this may mean snow, but for others it will result in more slush and mush.”

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.
