It’s been relatively dry across much of the United States this past week, with a widespread region experiencing less than 2% of  their normal precipitation. However, there is now the chance for a quick round of rain for portions of the Eastern U.S. during the latter half of the week.

Percent of Normal Precipitation Last 7 Days

The only catch is that the rain will be light, so we’ll remain pretty dry. The main reason for this light rain is that there won’t be much moisture associated with the storm system. Very little moisture is going to be drawn up from the south, as shown in the forecast precipitable water values.

ECMWF Precipitable Water Thursday

A cold front will deliver a brief bout of rain to the Ohio Valley and the Northeast, Thursday into Thursday night. There may also be a few isolated showers for the Southeast. In terms of timing, the rain for most locations will last only up to six hours in duration. A line of showers will move through, beginning in the St. Louis area and tracking up through the mitt of Michigan Thursday morning. That rain will move out of the region by the afternoon as it enters Kentucky, Ohio, West Virginia, western New York, and western Pennsylvania. As the sun sets Thursday evening, cold air will settle in, leading to the chance for light snow across Upstate New York followed by Vermont, New Hampshire, and western Maine. Up to three inches of fresh snowfall is forecast to fall in some of these areas. Further south where it’s a bit warmer, it will solely be a rain event for the major Northeast cities Thursday night. The rain will only extend as far south as New York City, but possibly it may briefly reach the Philadelphia area. The good news is that the rain will clear out and the front will have pushed through by the time the sun rises in New England Friday morning.

Rainfall will be very light, adding up to only about a tenth of an inch for most locations–possibly up to a quarter of an inch for localized areas.
