Unseasonably, chilly air was entrenched across the Northeast this past week as gusty, bone-chilling, northwest winds persisted. However, a big weather pattern change is forecast next week, which will usher much warmer weather into the region.

Before the warm-up, the chilly weather will persist this weekend. A widespread frost and freeze is expected across the interior Northeast from most of Pennsylvania north into New England Saturday night. Anyone with sensitive vegetation should be prepared for several hours of freezing temperatures this weekend.

Overnight lows tonight will average in the low to mid-20s across interior New England while slightly warmer upper 20s to low 30s will be found across the interior mid-Atlantic. In the coldest valleys of northern New England, teens are forecast.

Alongside the chill, a period of rain will move into the mid-Atlantic this afternoon and tonight. Enough cold air may be in place across central and northern Pennsylvania tonight for some wet snowflakes to mix in with the rain, especially for areas above 2,000 feet.

By Sunday, the rain will move out to sea, leaving behind chilly, dry, gusty northwest winds once again for the region. However, Sunday will be the last hurrah for the cold weather.

On Monday, a high pressure system will move into the Northeast, providing plenty of sunshine and light winds.

The major difference next week in comparison to this week will be the wind direction. Next week will feature widespread southerly winds helping to usher much warmer air in from the south, rather than this past week's northwest winds.

Widespread highs in the 50s this weekend will be replaced by 70s and even 80s by the middle and latter part of next week, including major cities such as Washington, D.C., to Philadelphia and New York City. However, the warm-up will come with a price.

After Monday's dry weather, intermittent rain will be forecast through much of next week for the region as several storms cross the region. Although a complete washout is not expected next week, we recommend keeping the umbrella handy.
