Another great day!

 I hope all y’all had a great Labor Day weekend.

Sunshine and low humidity continues in the Northeast and Northern Mid-Atlantic states into Wednesday. The next cold front arrives later Wednesday and Thursday with the risk for showers and thunderstorms.

Today

Another quiet, beautiful weather day is in store for the vast majority of the region, with a mix of sun and clouds. Those with the best chance of seeing isolated rain showers will be mainly across northern portions of the region, due to a backdoor frontal boundary, but this will be the exemption to the rule and these showers should be short-lived with little in the way of rain. That backdoor cold front will stall out and a southwest flow will mean warmer and more humid air will surge north into the region for the next couple of days.

We can see a disturbance over the Upper Great Lakes and Midwest. This disturbance is associated with the stronger cold front that will be approaching tomorrow.

   

The rest of the week

Tomorrow will start out similar to today. But a cold front will drop in late Wednesday and Thursday. There could be a few isolated showers Wednesday morning for western and northern parts of the region, but the bulk of the rain will start to move in during the afternoon moving north to south. Along with the rain showers there will likely be scattered thunderstorms, with the threat for isolated storms to become strong to severe. The Storm Prediction Center has outlined western and northern Pennsylvania along with western into central New York State at a Marginal Risk for Severe Thunderstorms Wednesday afternoon and evening in which some strong damaging wind gusts will be the primary risk…But small hail and heavy rainfall will also be an issue. Locally heavy downpours may result in some flash flooding and poor-drainage flooding.

 

The front will slowly work from north to south cold on Thursday, while conditions will be clearing north of the Boundary, those along and south of the boundary will be seeing mostly cloudy and a humid day. With the front will come the risk for scattered showers and a few thunderstorms mainly during the afternoon and evening. The day doesn’t look to be washout, with things clearing up late Thursday into Friday morning. Pennsylvania, Maryland, Delaware and New Jersey will have a very low chance for strong storms, but with the higher humidity, there could be a few heavy downpours leading to the threat for some localized flooding.

 

Friday will see high pressure build in, producing clear skies and low humidity and cooler temperatures. Saturday is looking to be a mostly great day, but I can’t rule out the threat for a few isolated showers over southwest Pennsylvania.  Sunday the high pressure will be starting to depart, as a cold front approaches from the west and north. Out ahead of the front conditions will become a bit muggy. The front will make things a bit unsettled, but I don’t think the rain will amount to much. High pressure builds back in for Monday, providing sun and mostly dry conditions.  The high pressure will stay in control for Tuesday, both Monday and Tuesday will see fall-like temperatures with lower humidity
