MONDAY SNOW
March 25, 2013

UPDATE:

6:00 PM, Monday, 25 March, 2013

The Baltimore official snowfall total for Monday at BWI-Marshall Airport as of 5:00pm was 3.2 inches, beating the 1933 record of 2.5 inches. The final snowfall total for Monday will not be determined until after midnight.

Today’s storm was strengthening off the coast during the afternoon and the dramatic NASA satellite image below demonstrates how surprisingly similar this deepening low pressure center  resembles a hurricane.

 PREVIOUS ENTRY:

The snowfall finally started in the predawn hours on Monday with temperatures close to the freezing point so it started to accumulate. By 8:30am as much as 5 inches of snow was reported around the area. More is on the way.

Image

The National Weather Service 8am surface map shows the strengthening offshore low with the weakening low over Ohio. The offshore low will be pushing moisture toward the Baltimore area the rest of the day with what is expected to be a combination of rain and snow.

Image

The storm total forecast map indicates a potential for a near record snowfall for Baltimore. The record is 2.5 inches set in 1933. It’s tough to make snow in late March.

The snow totals reported to the National Weather Service as of 8:30 this morning are as follows.

Spring Snow Possible
March 24, 2013

We’re four days into Spring and just a week away from Easter. Yet here we are, still facing the possibility of snow. Fortunately, for those of you cringing at the mention of the cursed “s” word, you have climatology on your side. The higher sun angle of late March makes it that much more difficult for snow to accumulation.

That being said, some snow accumulation is possible, especially north and west of Baltimore City. This will definitely be one of those elevation-driven snows.

Below is a preliminary snow forecast, and this mostly applies to GRASSY SURFACES. Expect less snow on the roads, if any at all. Roads that are south and east of I-95 are especially likely to just remain wet.

Bottom line, proceed with caution tomorrow. Any bit of ice or slush on the roads could make things slippery.

Snow Forecast through 6 pm Monday:

Precipitation Timeline:

Sunday Evening: a light wintry mix possible, little to no accumulation expected.

Sunday Overnight: wintry mix changes over to wet snow, especially north and west of I-95. Trace accumulations possible, mostly on grassy surfaces.

Monday Morning: wet snow for most, mixed with rain south and east of I-95. Minor accumulation possible, mostly between 5 am and 10 am.

Monday Afternoon: wet snow mixed with rain, little to no additional accumulation expected.

Monday Evening: wintry mix tapers off from west to east.

Significant Snow Event Possible
March 4, 2013

It’s the best chance we’ve seen for significant snow around Baltimore in almost two years. A winter storm will take aim at the Mid-Atlantic midweek, with a combination of heavy rain, snow and strong winds. Potential impacts of this storm include travel delays, downed trees, and scattered power outages.

The National Weather Service has issued a Winter Storm Watch for Tuesday night through Wednesday night for the areas in blue. This includes the possibility of snow accumulations of 5 or more inches.

We’ll have a better idea of possible accumulations starting tonight and especially by tomorrow. For now, here’s a general overview of the event:

Tuesday Night

Rain or snow showers could begin as early as Tuesday evening, but the steadiest rain and snow should hold off until after midnight. A wintry mix is possible for areas south and east of I-95, while areas north and west have a better chance of getting some accumulation by sunrise.

Wednesday

Once the sun rises at 6:33 am on Wednesday, the temperatures will begin climbing. This will cause more rain to mix in with the snow, and will severely cut down on the chances for accumulation. During the day, as temperatures climb into the mid 30s, only the heaviest bands of snow will be capable of accumulating. Regardless of the type of precipitation your neighborhood gets, Wednesday will be a cold, wet, and windy day with slippery travel conditions.

Wedneday Afternoon and Evening

As the sun lowers on Wednesday afternoon and evening (sunset at 6:03 pm), the temperatures will begin falling. During this time, the storm will be moving to our east and intensifying. The winds will increase, and the precipitation will become heavier. Cold air will move in from west to east, causing the rain/snow line to shift east as well. This time period brings the best chance for accumulating snow across all of the Baltimore Metro Area, as well as the northern parts of the Eastern Shore and Delaware.

Thursday

The snow will taper off Thursday morning as temperatures fall into the low 30s degrees. Any snow already on the ground will continue to make travel difficult, and the roads will start to freeze over wherever it drops below 32 degrees. Strong winds will make the day feel raw with high temperatures only near 40. The winds will slowly decrease into Friday.

March Snowstorm? It’s Possible
March 3, 2013

Spring begins in less than 3 weeks, but winter refuses to step down early. A late season snowstorm is in the making, and could take aim at the Mid-Atlantic this week.

The storm in question is over the Northern Rockies right now.

low

From there, it will dive south into the Plains, before moving into Maryland late Tuesday. It will intensify as it moves off the coast, bringing concerns for strong winds and heavy snow on Wednesday.

snow possible

How much snow we get depends on the storm’s exact track, a detail that remains fuzzy at this point. The latest forecast models bring the low somewhere between southern Virginia and northern North Carolina. If you’re a snow lover, you’ll be pulling for the more northerly track.

Regardless of the track, this storm will have to work that much harder to accumulate, given how late it is in the season. The month of March means longer days and a higher sun angle, which helps to warm the roads and lower atmosphere. In order to get accumulation, the snow will have to fall faster than it can melt. Only the heaviest snow bands will be capable of this.

The WBAL TV weather team will keep you updated as this storm approaches. Until then, be mindful of this potential storm and its impacts. Any combination of snow and wind could hinder travel or cause power outages Tuesday night through Thursday.
