The Lehigh Valley could get its first 60-degree day in nearly four months this week.

Temperatures are expected to jump into the 50s before reaching a high in the mid-60s Saturday, according to the National Weather Service in Mount Holly, New Jersey.

Sunday marked the first day of meteorological spring, which is how meteorologists and climatologists break the seasons down by the annual temperature cycle. While Sunday’s temperatures were pretty close to typical winter highs and lows, temperatures are expected to be more “spring-like” later this week and early next week.

Here’s a *preliminary* summary of Meteorological Winter 2025-26. As everyone knows by now, cold and snowy, but also a bit on the dry side overall. For the I-95 corridor, it was generally the coldest and snowiest meteorological winter in over 10 years, in some cases much longer. pic.twitter.com/6ZQ6kDj6Nt

“Looks like there’s better chances for warmer conditions over the next few weeks,” said Mike Lee, meteorologist for the local weather service office.

The last time temperatures were in the 60s was Nov. 10, 113 days ago, weather service data states. It’s the second-longest stretch of time without a 60-degree day since the turn of the century. The longest stretch during that time frame was between November 2002 and March 2003, at 120 days, that data states.

The average temperature for the winter was about 27 degrees, roughly 5 degrees below average for the winter in the Lehigh Valley. Additionally, snowfall reached 35.5 inches, about 9 inches above normal for this time of year, Lee said.

While there’s always a chance of snow in March, and even April, the likelihood of that happening in the next week or so is very low, and the probability of that decreases as the weeks go on, Lee said. The National Oceanic and Atmospheric Administration is predicting temperatures will be above normal over the next two weeks.

Before the warmup, there is a chance of rain several days this week. Heavy rainfall is not expected, but Lee noted any rainfall would be beneficial while the region remains under drought conditions. Both Lehigh and Northampton counties have had below-average rainfall over the last six months.

Any rain should help melt the lingering snowpack that has remained from the storms earlier in the season. The Allentown area had 32 days straight of snow cover, marking the 15th highest streak for region in recorded history, according to weather service data. Snow cover lasted from Jan. 18 until Feb 18.

Here is the extended forecast from the National Weather Service:

Wednesday: A slight chance of rain after 1 p.m. Mostly cloudy, with a high near 53. Calm wind. Chance of precipitation is 20%.

Thursday: Showers likely. Cloudy, with a high near 51. Calm wind becoming east around 5 mph. Chance of precipitation is 60%. New precipitation amounts between a tenth and quarter of an inch possible.

Friday: Mostly cloudy, with a high near 54.
