Weekly Planner: Record heat to start the week

/by

Good morning! What a wonderful weekend that was. After seven straight weekends with measurable rainfall, we finally broke the streak – and the heat built into the Northeast states on Sunday, with temperatures rising into the lower 90s. The heat will actually peak today, with temperatures expected to approach record highs for the day, in the middle 90s. 850mb temperatures (about 5000 feet above our heads) will actually be a bit cooler closer 19 to 20 C today, than what models had back last week. But the surface temperatures will warm as southwesterly winds increase.

In addition to the increasing surface temperature will come rising dew points, resulting in relative humidity values much higher than they were on Sunday. Heat Index values are expected to rise into the upper 90s and eventually near or over 100°F in many spots by this afternoon, especially over Northeast New Jersey and the Lower Hudson Valley.

Weekend Outlook: Heat Builds in the Northeast

/1 Comment/by

For seven straight weekends now, we have discussed the possibility of showers, cooler than normal weather, and unsettled conditions. This weekend will finally buck the trend. Warmer, benign weather with plenty of sunshine is expected for the entire weekend in the Northeast states as high pressure settles in. As time goes on, temperatures will increase thanks to a building mid-level ridge.

On Saturday, temperatures will begin warming up with highs in the mid-upper 80s. By Sunday, high temperatures are expected to reach 90 degrees or higher, as southwest winds usher in increasingly warm and humid air. The heat will likely peak on Monday, as 850mb temperatures between 20°C to 22°C expand to encompass much of New England. There is potential for high temperatures in the mid to upper 90s and Heat Index values near or over 100°F in the urban corridor.

Heat Builds in the Plains, Cooler Weather Persists in the Northeast

/by

While it’s been very warm and muggy at times, during the May and into beginning of this month, more periods of some cooler and some wetter weather have domnated over the Northeast US. Unfortunately, we don’t expect this general theme to be changing very much over next week or two. In fact, this summer isn’t looking to be very hot one for Northeast, based on our summer forecast research into analog years that feature similar pattern for the Spring months, (March to May) and current trends with a more neutral ENSO. But there might a be few changes for awhile during the middle to later part of this month.

Warmer Today, Then Cooler & Unsettled Weather Returns

/1 Comment/by

Happy Tuesday! Today will be much warmer and more humid than yesterday. More upper-level ridging with subsidence builds into Northeast today. This will cause low clouds again this morning, to clear for more sunshine by the afternoon hours. Southwest winds will also help temperatures rise well into the 80s across the region. Along the south-facing shores, sea-breezes will keep temperatures in the 70s.
