NYC Area Forecast: Autumn air arrives this weekend

/0 Comments/by

The remnants of Hurricane Michael brought plenty of rainfall to parts of the area overnight Thursday into Friday morning, with bands rotating onshore and producing localized flooding. This was especially true over parts of Southeastern New Jersey, where upwards of 4″ of rainfall was observed in some locations.

The reality of the situation is that it could have been much worse in our area. Michael was pushed seaward by an incoming cold front, and the pattern was slightly more progressive. If not for this, we could be dealing with a prolonged heavy rainfall event and widespread flooding concerns. Instead, Autumn like weather is expected to shift into the area this weekend.

NYC Area Forecast: Impacts from Michael today with rain, storms

/0 Comments/by

Moisture from the remnants of Hurricane Michael will stream northward over the next several hours, and its interaction with a frontal boundary in the Northeast will prove sufficient to develop numerous showers and thunderstorms. A warm front will lift northward through the Mid-Atlantic later this morning, providing the first impetus for shower and thunderstorm development. Some of this rain is expected to be “torrential” in nature – heavy and sporadic, but many cause localized flooding.

Tropical moisture is responsible for a large majority of our heavy rain threats around the Mid-Atlantic and Northeast this time of year, and when it interacts with a frontal boundary, it can often mean trouble. While this threat remains progressive (i.e, it will be out of here by Friday) it is still noteworthy. After the warm front lifts northward later today, instability is expected to build across the Mid-Atlantic, New Jersey and the NYC Metro Area.

NYC Area Forecast: Michael impacts Thursday, improving weekend

/0 Comments/by

As a potentially catastrophic Hurricane Michael churns in the Northern Gulf of Mexico, the weather in the Northeast remains relatively quaint. Low clouds and fog are again present in the NYC Metro area this morning, a common theme over the past few days. What’s been causing it? An inversion – basically, a temperature change in the atmosphere that “traps” moisture near the surface, leading to fog and drizzle. This has been present almost every morning since Sunday.

The good news, in the short term, is that these low clouds are finally expected to burn off today. Partly sunny skies should become common during the afternoon hours in the Northeast and Mid-Atlantic states today as higher pressures and some sinking air do their work to reduce moisture content. After a relatively pleasant afternoon and evening, the forecast will take another unsettled turn.

Hurricane Michael a Category 4, still strengthening this morning

/0 Comments/by

Update 8:15am: The National Hurricane Center says that Michael has strengthened again this morning, with maximum sustained winds now 145mph.

Hurricane Michael strengthened again overnight, and is now approaching the Florida Gulf Coast as a life-threatening Category Four hurricane with maximum sustained winds of 145mph.  The National Hurricane Center is now suggesting that the storm will make landfall as a Category Four hurricane with 145 mph sustained winds. No hurricane has ever hit the Florida Panhandle at such a strength. Records date back to 1851.

The strengthening of the storm overnight was feared by many forecasters and meteorologists as early as Tuesday afternoon, when the storm system began to appear more symmetric and approach warmer waters and lower shear. These conditions tend to promote increased organization and strength of tropical systems. The storm was still strengthening as of this morning, with a minimum central pressure down to 937hPa.
