NYC Weather Update – Apr 27, 2020

An active weather pattern brings yet another week of cool, rainy weather. Tuesday will be the only day with sunny skies and near normal temperatures with high pressure briefly building in. Otherwise, a couple slow moving storms will bring clouds and rain the rest of the week. This will result in temperatures largely running below seasonal averages. I suppose that’s some incentive for people to stay safe and quarantine at home?

Rest of today – early rain chances should diminish steadily. High temperatures cool, only around 50ºF under the influence of northerly flow as the slow moving coastal storm that impacted us yesterday and today moves off to the northeast. Clouds should start to diminish later in the day. Overnight lows in the low-40s.

Tuesday – we should see a brief window of sunny skies and dry weather as high pressure builds and passes over for the day. This break in rainy weather should allow temperatures to climb into the low-60s. Overnight lows in the mid-40s.

Wednesday – the reprieve from dreary conditions barely lasts a day as yet another storm system takes aim at the area. With the high pressure Tuesday slow to move east, this next storm will be similarly as slow moving as this past weekend’s storm. The result for Wednesday, even if we don’t get too much in the way of rain, will be cloudy conditions and cool, southeasterly onshore flow ahead of an advancing warm front. This will cause temperatures to cool into the mid-50s. Overnight lows barely budge, and hover around 50ºF.
