Damp, cloudy weather conditions persisted Friday as Long Island continued its imitation of the Pacific Northwest.
The National Weather Service forecast for Nassau and Suffolk counties called for periods of rain during most of the day, with possible thunderstorms.
Temperatures are steady, around 50 degrees, the service’s Upton office said, with winds from the northeast at 14 to 18 mph. Some gusts could push to 30 mph.
Most of this week has been rainy with cooler than normal temperatures for May. News 12 Long Island meteorologist Rich Hoffman said the average daily high for this time in May is about 65 degrees.
Hoffman also called for more wet weather Friday with improving conditions for next week.
Until about late Sunday morning, however, it stays damp; new rainfall amounts between one-quarter and one-half inch are likely for Friday, the service said.
The rain Friday is likely to generate coastal flooding during times of high tide, the service said.
A coastal flood warning is in effect from 7 p.m. to 11 p.m. Saturday, for Nassau and parts of Suffolk, the service said.
Eastern Suffolk is under a coast flood statement from 8 p.m. Friday to 2 a.m. Saturday.
Friday night and into the wee morning hours Saturday call for stretches of patchy fog and a chance of showers.
Clouds continue with daily highs in the upper 50s. Winds start out from the east at 7 mph before shifting south in the afternoon.
For Sunday, Mother’s Day, Hoffman said clouds and showers are possible during the morning with some clearing and a mix of sun and clouds in the afternoon.
Daily highs range between 62 and 67 degrees with a breezy south wind shifting west later in the day.
