The rain-dredged northeast has another threat of severe weather Wednesday, including New York and Boston, as a cold front pushes east from the Great Lakes.
The Storm Prediction Center (SPC) warns Wednesday of a slight risk (level 2 out of 5) of severe weather for the coastal parts of the Northeast.
“Scattered strong to severe thunderstorms are possible Wednesday afternoon from New Jersey north to southern New England. Hail and damaging winds are expected to be the main threats, ”said SPC.
Showers and scattered clouds are moving over western parts of the region Wednesday morning, left by a series of thunderstorms Tuesday evening.
Although the skies are clear of clouds and rain in most of the towns along the coast, thick forest fire smoke from large western fires has settled in the area, giving the sky a thick sky. orange and red tint at sunrise.
The fires show explosive activity and throw smoke into the air so high that it is trapped in upper atmospheric air masses and carried across the country, where in some places it is able to make its way into the air. path to the ground.
Images of New York City shrouded in smoke from fires thousands of miles away show the smoke mixed to the surface, creating an eerie scene Wednesday morning.
The strong cold front passing through Wednesday night is expected to clear the sky behind it as the front pushes smoke out at the surface of the region.
At midday, a generally clear sky along coastal areas could provide the energy needed for daytime heating to trigger strong to severe storms in the afternoon and evening.
“The timing of the convection will be a key factor in determining whether severe weather events may materialize in the region,” said the National Weather Service in New York City.
If the cloud cover from Wednesday morning showers persists until noon, the serious threat could be hushed up.
The pressing cold front east of the Great Lakes will begin to trigger showers in western New England before moving further towards the coast, interacting with marine moisture that will help fuel the storms.
Supercell thunderstorms capable of producing large hail and destructive wind gusts will be possible as the storms move eastward during the afternoon.
Cities like New York, Boston and Philadelphia have the greatest chances of seeing severe storms through tonight.
Rain appears to be relentless in the region after weeks of precipitation already far exceeding monthly averages.
Central Park in New York City has already collected 9.15 inches of rain this month, 6.45 inches more than normal. This makes it the fourth wettest July on record, according to the NWS.
Up to 2 inches of precipitation is possible, particularly near the coast in the northeast and as far as New England. The highest totals will be heavy localized showers where the heaviest storms pass.
“The local heavy rainfall is expected to be brief, but isolated flash floods cannot be ruled out due to the wet soils,” NWS Albany said.
Wet soils in the region could cause flooding problems, as well as in metropolitan areas. The Weather Prediction Center has issued a marginal risk of excessive precipitation on the northeast coast of Delaware in Maine due to the potential for flooding.
After the cold front moves away from the Atlantic coast on Wednesday evening, temperatures behind the front will be milder and more seasonal, with dry air replacing the humid and warm conditions that have taken over this week.
