Nor’easter to bring heavy rain, strong winds and snow to Northeast

Snow could fall in New England as another Santa Ana wind event approaches.

Up to 1 inch per hour of heavy rain was reported in parts of Maryland and Delaware Saturday morning. There has also been some flooding.

The heaviest rain is expected to pivot into some of the northeastern cities throughout the morning, and winds are expected to increase as well, gusting, at times, at over 30 mph.

As the storm strengthens and moves north and east, it should pull some colder air in from the north, and snow is expected to replace the rain in parts of New England.

Winter storm warnings and winter weather advisories have been issued for parts of the region from Connecticut to Maine.

The snow accumulation forecast is a little tricky. The atmosphere is relatively warm and will likely remain so throughout the entire event. Even though some cold air should help produce snowfall, it’s uncertain how much snow will actually fall due to the marginally cold temperatures.

Because of this, most snow will accumulate on grassy surfaces and where there is enough cold air. This could make driving very treacherous in spots, and the heavy wet snow, combined with gusty winds, could cause power outages.

States will likely see 1 to 3 inches of snow, though some areas, especially northeast Connecticut and Massachusetts, could see 3 to 6 inches of snow. Southeast Maine and a couple of spots in Massachusetts will likely see the most snow — possibly over 6 inches.

In California, the Bond Fire has now reached over 7300 acres, and is 30% contained.

The peak of the latest Santa Ana wind event has passed, but winds could remain gusty through Saturday and move at up to 35 mph. Relative humidity could be as low as 5%.

Sunday will be relatively calm in terms of wind across Southern California.

Another Santa Ana wind event will arrive Monday or Tuesday. It’s unclear how low the relative humidity will be, but regardless, there will likely be a period of enhanced fire conditions.
