While 1½ to 2 inches of rain is forecast for Friday into Saturday, Wednesday is looking at temperatures in the upper 50s to 60 degrees, possible light evening drizzle and fog after midnight, forecasters said.
Minor coastal flooding is expected Wednesday night for Nassau's South Shore, the National Weather Service said in a special statement. At play is the convergence of continuing light southeasterly winds and a higher astronomical tide due to the full moon. Tides are expected to run around a foot above astronomical levels, with high tide occurring between 8 to 10 p.m., the service said.
The arrival of a warm front means temperatures Thursday are forecast to rise to the low to mid 70s, and around 70 for Friday, when "a dousing of rain" is expected to start in the midafternoon and last through midmorning Saturday, said Tim Morrin, weather service meteorologist in Upton. Look for steady rain, at times heavy, with an occasional thunderstorm, he said.
Saturday and Sunday look to be partly to mostly sunny with highs near 70 and 71, as of Wednesday's forecast. But don't look for "a sustained transition to fair weather," Morrin said, as "the atmosphere is a little unsettled" and there's a chance of more showers on Monday.
