Since Memorial Day is typically deemed as the unofficial start to summer, many people of the Northeast may find it hard to believe that frost and freezing temperatures are a concern tonight.
The same unseasonably cold air that led to substantial snow in the northern New England mountains will make for a chilly night through the Northeast tonight.
West of I-95 (and west of I-81 from southern Pennsylvania to northern Virginia), temperatures will be cold enough for areas of frost to form.
The same can be said for northern Michigan and southern Ontario.
The threat for a hard freeze will be reserved for the coldest locations, while clouds should prevent both a frost and freeze across northern Maine.
"The [frost/freeze] event is a concern for vegetables, flowers and berries in the area," stated AccuWeather.com Expert Senior Meteorologist Alex Sosnowski, and one residents should prepare for even if tonight's forecast low is slightly above freezing.
"Temperature forecasts are made for eye-level. However, temperatures near the ground on clear, calm nights can be 5 to 10 degrees lower for several hours, especially around and just prior to sunrise," Sosnowski continued.
The frost and freeze danger will center on northern New England and upstate New York Monday night, while milder air pours across the Great Lakes and central Appalachians.
Neither night will those in Boston, New York City, Philadelphia, Baltimore, Washington, D.C., and these cities' close suburbs have to worry about waking up to frosty flowers or windshields.
Significantly warmer air is on the horizon for the entire Northeast, which will have many residents switching from using their heaters this holiday weekend to air conditioners later this week.
The chilliest air of the season so far will settle over much of the Northeast Thursday into Friday and will bring frost to more areas than experienced frost early this week.
Tropical moisture from the approaching Odile will deliver another round of heavy rain and flooding downpours to the interior Southwest by the middle of this week.
The remnants of Odile have the potential to bring heavy rain and flooding to parts of the Plains and Midwest late this week after hitting the Southwest.
