Monday's cold, bright conditions set the stage for the rest of the week, according to the National Weather Service.
The Martin Luther King Jr. holiday on Long Island was sunny and clear but temperatures didn't touch the freezing mark in most places and there was a wind chill of just 5 to 15 degrees that will plunge in the evening, the service said.
"This week`s weather will be dominated by high pressure moving across the eastern United States, resulting in consistently clear skies and light winds. Tonight`s lows will range from near 20 in New York City, down to the single digits across the interior," the service said in its regional summary Monday afternoon. "Tuesday`s highs will be in the lower and mid 30s, remaining below freezing in some isolated interior spots."
Tuesday should be a close twin of Monday, and that night also will be markedly cold, with the temperature falling to about 18, the NWS said.
Wednesday should also be bright and sunny, with a high of about 37; Thursday will be much the same but slightly warmer, with a high of 42.
By Friday, the sun also will rule the weather and thermometers should reach 44, the weather service said.
There is a 50% chance of rain on Saturday, however, and the odds of Sunday showers are about 40%, the NWS said.
