We’ve been tracking this same storm since Friday now, which began the multi-day threat for severe weather. It has also been responsible for bring heavy rain to portions of the South over the weekend. Now it’s the East Coast’s turn for the unsettled weather as the weak low pressure begins to take a turn up the coast before moving inland into New England Wednesday night.
As you wake up Tuesday morning, a heavy line of rain with embedded thunder may move eastward through eastern North Carolina and Virginia. Rainfall rates will exceed half an inch per hour at times, and of course this will be happening during the morning commute. For other locations, a lighter rain is expected in the morning from the eastern Ohio River Valley through the DelMarVa. In the afternoon, the rain will continue to chug to the north and east. Rain is forecast from the interior Northeast through the Mid-Atlantic coast. Rain showers may also sneak into the New York City area and south New England by the evening hours.
Then into Tuesday night, all of the Southeast will be clear of the rain while it becomes solely a Northeast event. Rounds of a light to moderate rain are likely across most of the Northeast and New England during this time period. Heavier rain is possible in the Appalachian Mountains due to the enhancement in lift due to elevation.
On Wednesday, we are still going to be talking about this storm. The offshore low will have taken over by now, and that low will usher in rounds of rain throughout the Northeast. From the Tennessee River Valley through Maine, rain showers are expected. Thankfully, this will be a rain event from everyone and we will not have to talk about snow because temperatures will finally be above freezing. It’s only taken then end of April for this to happen!
By Wednesday night, rain will have cleared out of the Ohio and Tennessee River Valleys as well as the southern Mid-Atlantic region. Rain showers will persist, however, from the northern Mid-Atlantic through New England. Temperatures may near freezing in northwestern Pennsylvania and western New York, so there is the chance for a wintry mix.
Then on Thursday, the low pressure will have moved inland and into New England. This will allow for gustier winds with gusts up to 40 mph at times. Thankfully, since the low pressure will be weak, winds won’t be much of an issue. The rain will be the main story with rain showers continuing across New England and the interior Northeast. Clearing at the coast will occur by the afternoon for many locations.
Finally by Thursday night, the storm will move into Canada, but a few lingering, light rain showers may be possible near the Canadian border.
