Long Islanders can expect seasonably pleasant conditions Monday and Tuesday with the high both days just below or about 70 and chilly nights, before Wednesday is expected to bring rain in time for the evening commute, according to the National Weather Service.
The roads and train platforms could be slick early Monday from possible rain overnight but for those driving into Manhattan to watch the Columbus Day Parade, it will start under mostly clear skies.
The low Monday night is expected to drop to about 48 degrees with clear skies, according to the weather service's Upton office. Long Island should be bathed in sunshine for Tuesday with a high of about 62 and increasing clouds at night when the low will likely dip to 50, the weather service said.
By Wednesday morning, the 48 hours of sunshine will be just a pleasant memory as Long Islanders wake up to threatening skies, temperatures in the 50s and a 90% chance of rain — between three quarters to an inch — after 2 p.m. and continuing through the evening commute and into Thursday morning, the NWS said.
Compared to early Wednesday’s possible light rain, by later in the day the front will be “more wet, a little more energetic, so we could see some thunderstorms … heavy rain,” said Da’Vel Johnson, a NWS meteorologist.
Thursday is a breezy dry-out day as the rains predicted for Wednesday move on and clear skies and temperatures of about 59 move in, forecasters said.
At night Thursday, expect partly cloudy skies and breezy conditions with a low across Long Island of about 46 degrees.
Friday through the rest of next weekend will likely see a repeat of Sunday's dry seasonable conditions.
Mostly clear skies are in the forecast for Friday into next Sunday with highs in the mid-60s and overnight lows in the high 40s, the weather service said.
