Nor’easter Ensemble Update January 31, 2009

The morning run of the computer models trying to get a handle on next week’s possible nor’easter continue to show a near miss for the Baltimore area.  As we posted last night, the ensembles are the mean result of a given model processed many times with slight variations introduced for each run.  These ensemble means [...]

Next Week’s Nor’easter January 31, 2009

For the past few days computer models have been advertising a strong low pressure storm system moving up the eastern seaboard from Monday evening through Tuesday of next week.  These models have been producing a storm track that ranges from well inland to well off the coast and each scenario presents widely different weather possibilities [...]

What’s Next? January 30, 2009

Fairly quiet weather going into the weekend. A cold front will be moving across the region on Friday but moisture is limited and if anything develops it should only be in the form of flurries, sprinkles or snow showers. In the satellite picture above, a lot of what looks like clouds west of Maryland is [...]

Thursday View January 29, 2009

The image below is a NASA satellite image of the region at 11:45am Wednesday.

The image clearly shows snow on the ground deposited by the most recent storm. Western Pennsylvania and West Virginia are covered by a cloud deck but the gray/white shaded areas of the rest of Pennsylvania and the northern half of Maryland show [...]

Almost Over January 28, 2009

The two day winter storm is pulling away from the region this evening. Temperatures finally warmed into the mid-upper 30s in northern Maryland, bringing and end to the freezing rain and freezing drizzle. The last of the rainfall will be leaving with the storm. Refreezing of snow and ice melt will occur overnight so untreated sidewalks and  streets will [...]

Tuesday Storm Update January 27, 2009

The winter storm everyone is talking about is still on track and the expected impact on the region remains unchanged. This is not likely to be one of those blockbuster storms but the combination of snow, sleet, freezing rain and then rain, in that sequence, will disrupt highway travel for the next 24 hours. The [...]

Storm Brewing January 26, 2009

Temperatures have been falling from the 50s the area experienced on Friday and now a storm is brewing that will be moving into this colder air.

The morning satellite image shows extensive cloud cover over the eastern U.S. The latest storm is still developing in the Rockies and will begin to take shape in the southern [...]

Nor’easter Anniversary January 25, 2009

Today is the anniversary of a big nor’easter that plowed through the area not too long ago.

This was one of five storms in the Baltimore January weather record books that snow totals exceeded 10 inches.

Baltimore’s all-time coldest January 23, 2009

Today, January 22nd, is the anniversary of one of Baltimore’s most significant winter weather records.  On January 22, 1984 the temperature dropped to -7° at BWI, tying the record for the coldest temperature ever officially measured here.  That frigid benchmark has been reached five times since 1870 at our official National Weather Service stations, including [...]

Not As Cold January 22, 2009

The coldest air is retreating as a more zonal weather pattern develops across the U.S.

The satellite image above shows the relatively quiet weather over the western hemisphere.

The morning weather map show that the only significant storms are over U.S./Canadian border just east of the Rockies and off [...]
