Early spring weather will be persuading flowers and trees to bloom this week on Long Island with high temperatures in the 50s and showers expected Monday and possibly Tuesday and Friday, forecasters said.

Sunday's high was in the low 60s, about 10 degrees above average for this time of year. But more typical spring temperatures hovering around 50 will mark the rest of the week.

Rain to water those flowers is likely most of the day Monday, when the high is predicted to be in the lower 50s, dipping to 35 at night.

"The rain will become more steady mid to late afternoon and more widespread," the National Weather Service service said. "The widespread rain will continue into Monday evening and will be light to moderate at times....This low will move well out into the Atlantic late Monday night."

There may be "a few weak showers early Tuesday morning" and it will be mostly cloudy, the weather service said, with the high of about 49 degrees, dipping overnight to 34. 

Both Wednesday and Thursday look sunny with highs in the lower 50s, dropping to the mid-30s overnight, before a wet Friday. "Unsettled conditions return for the end the week with a warm front and low pressure impacting the area Friday afternoon into Saturday," the weather service said.
