There's a chance for another Nor'easter to develop to close out the weekend bringing the threat of rain, snow and sleet to the East Coast. This would be the third storm in less than two weeks if it forms and hugs the coast.

What are the chances?

Trend vs. Forecast: The trend of course is for this storm to pan out in another "Millers Type B" scenario.

The GFS (which at this time) is the only storm bringing it to Maryland. Other models are on the fence with the Low's positioning or they're shifting the storm south & east off the coast. Here's a look at the ECMWF model ensemble, which is a blend of several probabilities. This is usually the "go to tool" when there is so much model disagreement when forecasting. 

Notice how the bulk of the "L" - Low pressure locations are away from the coast. Therefore, at this time the forecast is still for this storm to "miss" Maryland - but the trend over the last week has everyone skeptical - including us.

What We Know

At this point what we know is that a strong area of low pressure will develop off the coast early next week, which will keep our temperatures below normal for the second week of March. Our average high this time of year should at least be in the 50s - but as you can see the trends will keep us in the 40s.
