Maryland Weather: Alert day tonight through Tuesday morning for snow accumulation

BALTIMORE – An alert day has been issued tonight through Tuesday morning for snow accumulation that will likely cause school and travel delays.

Snow will develop this evening and continue into Tuesday morning, totaling 2 to 3 inches, with some spots as high as 4 inches.

Light snow is expected to fall across the area this evening. Heavy snow should not be a problem in the first few hours of the storm, so widespread travel problems are not expected Monday evening. The snow density will increase from light to moderate on Monday night. This is when road conditions become slippery, especially on untreated surfaces. Temperatures should be cold enough to handle all the snow, and a little sleet or sleet is expected.

  • winds: When the snow falls, tonight through Tuesday morning, winds will appear light from the north at 5 to 10 mph. Blowing and drifting doesn’t seem like a problem. Late Tuesday afternoon and evening, it will get windier and colder, but by then, the snow will be gone.
  • Temperatures: Temperatures will be in the upper 20s to near 30 degrees during the snowfall. Road chemicals are very effective at these types of temperatures. Untreated surfaces will be slippery, but treated surfaces will be wet or slightly melted. Temperatures will drop into the teens Tuesday night with wind chills in the single digits.
  • Effects: Due to the timing of the snow falling during Tuesday morning, school delays are possible. Tuesday morning commutes will be much slower than normal due to snowfall, road crews processing highways, and locally wet and humid conditions. Tuesday evening’s commute should be better, but the weather is expected to be cold and windy. Any remaining untreated surfaces will turn to ice as temperatures drop and we will be concerned about refreezing Tuesday evening and night with any remaining snow or melted snow from earlier in the day.

when: It looks like the steadiest snow will fall late this evening into Tuesday morning. This won’t be a major storm, but it is the first large-scale winter weather event we’ve seen in a few years. People need to readaptate by driving in snowy conditions.

  • We will have to watch carefully Monday afternoon and early evening. Some models try to bring in snow a little earlier. There’s not complete agreement on this, but it’s something we’ll keep an eye on.
  • Right now, indications are that if this happens, the snow will be light and not a major issue, but we are flagging this and will monitor it in case the situation escalates.

Also noteworthy: Road treatment chemicals work best with temperatures above 20 degrees Fahrenheit. Therefore, any remaining snow/melting snow on roads/sidewalks will turn to ice even if it clears Tuesday night. It is important for people to remove this snow from driveways, sidewalks, paths, etc. so that Wednesday morning will not be too slippery. The wind will help dry out many surfaces, so hopefully this won’t be a widespread issue Wednesday morning.

good news: The snow will be perfect for sledding and making snowballs. There won’t be much of it (I wouldn’t expect more than 4 inches) to remove, so shoveling won’t be dangerous.


The snow gradually diminishes by lunchtime. Partially clearing, windy and very cold during the afternoon. Temperatures drop into the 20s. Wind chills fall in the teens by evening.

The rest of next week

The weather will likely be very cold but calm Wednesday through Thursday. Wednesday will be the coldest day, despite the sunshine, with high temperatures near 30, but wind chills mainly in the teens. On Thursday, the weather will be cloudy in most areas, with high temperatures in the mid-30s.

There is another chance of snow on Friday. It’s still too early to tell whether this storm will be more annoying or produce more snow. We will have more clear information about the potential for snow as the week develops. Stay tuned.
