Lots of sunshine and highs in the mid-to-upper 50s this week are surefire signs that spring has arrived on Long Island.

"High pressure over the region will result in sunny skies both Sunday and Monday," the National Weather Service said in its regional forecast. "Temperatures both days will climb into the 50s and lower 60s, which is a good 5-10 degrees above normal for this time of year."

Sunday will be sunny with a high about 55 and calm winds, according to the weather service. However, the low temperature is expected to dip to about freezing Sunday night.

Expect similar conditions Monday and Tuesday under mostly sunny skies with highs in the mid-50s. Wednesday looks partly sunny with a high about 55. Thursday’s high is predicted to reach the upper 50s.

That’s all warmer than the normal high of around 50 degrees for this week at Long Island MacArthur Airport in Islip.

Long Island will start to cloud over Wednesday night, but no rain is expected until Thursday night when there is a 30% chance of showers.

Friday brings a 40% chance of rain again with a high in the upper 50s.

The start of the next weekend be pleasant with sunny skies Saturday and a high in the upper 50s.
