Every computer model run seems to bring a change in the forecast track of the brewing coastal storm(s). Now that track has drifted farther out to sea, again, and estimates of the accumulating snowfall for Baltimore and Washington have dwindled some.

AccuWeather.com (and WJZ's Bernadette Woods) are now talking about 1 to 3 inches Tuesday, down from the 3 to 6 AccuWeather ventured earlier today. Surely that's a disappointment for some snow-starved Marylanders (and a relief to others).

The problem is the difficulty of predicting the storm track and speed, and the timing of the arrival of cold-enough air behind the front due to pass through tomorrow. The storm is still forecast to be a powerful one. But it now seems poised to hit New England much harder than the mid-Atlantic states. And the heaviest snow on the map has skidded north and east.

It could all change back again by Monday night, of course. But generally speaking, these predictions get better - closer to what actually is going to happen - as the time gets shorter.

Here's Accuweather.com's main story this evening. You can catch WJZ's forecast at MarylandWeather.com. Here's the latest forecast discussion from Sterling. Here's the official NWS forecast for BWI. And here's Capital Weather Gang's take.
