Evening Update: Dreary weather settles in

An unsettled and active weather pattern is upon us, putting an end to a long stretch of slightly above normal temperatures and very pleasant conditions with low humidity and clear skies. A frontal boundary near the area this evening will be the culprit behind the development of showers and isolated thunderstorms (although the storms appear pretty unlikely at this point with very little instability). These showers will remain in the area through the overnight hours as the disturbance moves along a mid level atmospheric gradient near our area. A break in the action is expected on Thursday, but we will be in between disturbances. By Thursday afternoon and evening, the chances for showers will increase yet again. Forecast models are hinting at the potential development of a low pressure area just south of Long Island very early Friday morning, which could bring some heavier/steadier rains to the area as well as a period of gusty winds especially on Long Island. Another system will move along the front and impact the area later in the weekend, from Saturday into Sunday with another chance of showers and steady rain. Temperatures throughout the period will run slightly below normal, especially on the second half of the weekend as the front sags south of the area and more cool/damp air is able to work in to the area.

Wednesday Night: Continuing chances of showers throughout most of the night – but the front will begin to sink south of the area overnight. Temperatures will fall accordingly.

Thursday: This looks to be the most pleasant day of the second half of the week. In between disturbances – most models have partly cloudy skies and highs in the 70′s. Increasing clouds by the evening as the second disturbance approaches.

Thursday Night: Clouds increase and a chance of showers return ahead of a disturbance approaching the area. Low temperatures end up only near 60 degrees in the city and upper 50′s elsewhere due to the cloud cover.

Friday: More showers and clouds throughout the day with the area being affected by a mid level disturbance riding along a front which will be stalled near the area. Cooler and more damp with high temperatures in the 60′s in many locations.
