November 21 Colder Winds Bring Snow To Central Maryland And Winter Storm Warning In The Mountains – Just In Weather
November 21, 2024
Thursday Morning Report
The squall line last night validated and even overachieved expectations. Winds gusted over 50 mph in many areas AND much needed rainfall added up to 0.94” in Baltimore through midnight. More was added afterward.
Colder air and a large upper-level trough will settle in Pennsylvania on Friday. This will bring in a taste of winter. The expectations for snow have now expanded to Central Maryland, and yes, it might be cold enough for some stickage on grassy areas.
A Winter Storm Warning is in place for the high mountains of far Western Maryland and West Virginia. Snow is still expected to reach 1-foot accumulation along with 50 mph winds.
Let’s take a look……
Morning Surface Weather
Storm 1, which brought us rain and wind, is moving away and sending much-needed rain to the drought areas of Metro New York and New England.
Storm 2 is the main event that will pivot from the Great Lakes and nearly stall in Pennsylvania on Friday. This will include a strong upper-level source of cold air and instability. Snow will spread our way and enhance over the Appalachian mountains.

RESTATING MY MESSAGE ABOUT DYSLEXIA
I am aware there are some spelling and grammar typos and occasional other glitches. I take responsibility for my mistakes and even the computer glitches I may miss. I have made a few public statements over the years, but if you are new here, you may have missed it: I have dyslexia and found out during my second year at Cornell University. It didn’t stop me from getting my meteorology degree and being the first to get the AMS CBM in the Baltimore/Washington region.
One of my professors told me that I had made it that far without knowing and to not let it be a crutch going forward. That was Mark Wysocki, and he was absolutely correct! I do miss my mistakes in my own proofreading. The autocorrect spell check on my computer sometimes does an injustice to make it worse. I also can make mistakes in forecasting. No one is perfect at predicting the future. All of the maps and information are accurate. The ‘wordy’ stuff can get sticky.
There has been no editor who can check my work while writing and to have it ready to send out in a newsworthy timeline. Barbara Werner is a member of the web team that helps me maintain this site. She has taken it upon herself to edit typos when she is available. That could be AFTER you read this. I accept this and perhaps proves what you read is really from me… It’s part of my charm. #FITF

Washington Nationals’ first-round draft pick Chris Hacopian inked his first professional contract Wednesday, a moment made sweeter by the fact it was just a 30-minute drive from home to get to Nationals Park and put pen to paper.
The 21-year-old second baseman and 11th overall pick in the 2026 MLB Draft has deep ties to the D.C. region. He’s from Potomac, Maryland, and played his high school ball at Winston Churchill, where he was named the 2022 Maryland Gatorade Player of the Year and a 2022 Washington Post All-Met selection.
According to MLB.com, Hacopian grew up a Nationals fan, admiring the likes of Ian Desmond, Danny Espinosa and others. He also played his first two collegiate seasons at the University of Maryland, where his father Derek played before him, before transferring to Texas A&M for his junior season.
With the Aggies, Hacopian hit .319 with 11 home runs and 41 RBI across 42 games en route to being named First-Team All-Southeastern Conference and a Third-Team All-American by Baseball America, the Nationals said in a news release.
After inking his contract Wednesday, Hacopian donned his new jersey and ball cap and stepped onto D.C.’s beloved diamond as a part of the Nationals organization for the first time.
“That was so cool, oh my gosh. I’ve been in the stands like, 100 times, but being on the field is so different,” he said.
Hacopian was ranked 14th among MLB Draft prospects by MLB.com. The 6-foot-1-inch, 210-pound second baseman boasted one of the best bats in college baseball, according to MLB.com, with excellent control over the strike zone and feel for the barrel, along with solid pop.

The state said the five recently traveled together to “a location in the U.S. experiencing an active measles outbreak.”
Maryland health officials confirmed five more measles cases, all in Carroll County.
“These individuals recently traveled together to a location in the U.S. experiencing an active measles outbreak,” the state Department of Health said in a release.
The agency said others may have been exposed on the afternoon of July 13 in the emergency department waiting room at Carroll Hospital Center in Westminster.
Another measles case recently prompted warnings from health officials in Maryland, Virginia and the District. On June 17, a Maryland resident traveled through Dulles International Airport and visited a D.C. urgent care clinic.
Measles is highly contagious. It can spread through the air through coughs, breathing, and sneezes. Early symptoms can include fevers of over 101 degrees, coughs, runny noses, watery eyes and face or body rashes.
It can take up to 21 days after exposure for the first symptoms to appear, and those who are not fully vaccinated or otherwise immune to measles are especially vulnerable.
The five new measles cases in Maryland bring the state’s year-to-date total to nine. The state health department confirmed three cases in 2025, and one in each of the previous two years.
“All Marylanders should review potential exposure times, watch for symptoms, and confirm they are up to date on their measles, mumps and rubella (MMR) vaccinations,” the health department said.
