Quiet Cloudy Gloomy Day Rain Thunder Tonight
Windy Colder Thursday Through The Weekend
The day ahead looks to be a cloudy gloomy one as a warm front lies to our south and we wait for a developing storm that will start to strengthen tonight. It will be heading up the Appalachians and into NY State, intensifying into a major storm along the way. The impact here will be a cloudy gloomy day today and a 6 hour shot of heavy rain tonight with the chance for a thunderstorm or two before daybreak on Thursday.
The satellite and radar shows us in lots of clouds. Dense fog covers many areas from Northeast Virginia to Southern New England this morning but there isn’t much in the way of rain yet on the regional radar. That will start to fire up later today as an upper trough swings east and low pressure begins to develop. Temperatures today for most of the area will hold in the upper 40s to mid 50s.
Tonight the cold front sweeps through with that solid line of showers in thunderstorms mainly between midnight and 7am. It goes in and out quick. It will produce between 1/2 and inch to as much as an inch of rain in some places and then it is done. What follows Thursday will be increasing winds from the northwest. Wind Advisories are in effect for Central Pennsylvania and I would look for those advisories to spread eastward into Southern New England. Winds will gust from the northwest at 40 mph or more on Thursday from Pennsylvania to Southern New England. Other weather service offices will likely catch up on this later today and tonight. Gusty winds with some sun and clouds on Thursday will keep temperatures in the 40s.
This storm is going to open up the Great Lakes to a significant lake effect snow event from Northwest Pennsylvania to Southwestern NY and the east and north of I-90 into North Central NY. Snow will also fall in Northern New England as has been the case this entire winter. This gets underway Thursday morning as the low moves northward into Southeastern Canada and then redevelops in the Gulf of Maine.
We will stay windy here right into Friday. There is another upper trough that will be moving through and that will bring down colder air for later Friday and for the weekend. Look for some sunshine Friday and sunshine for Saturday and Sunday. However temperatures Friday will be in the 30s to near 40 for highs. Saturday and Sunday highs will be just in the low to mid 30s. It appears the next weather system will be approaching with the chance for some rain or showers late Monday or Monday night. By then of course the cold air will be long gone.
