BETHLEHEM, Pa. - Some of the coldest air of the month was in place Sunday morning in the Lehigh Valley but big changes are in store the next few days.
It was 20 degrees at 7 a.m. at Lehigh Valley International Airport.
Sunday’s seasonably chilly temperatures will be a few degrees shy of normal before turning warmer Monday and reaching into 60s later in the week, according to the National Weather Service.
The spring preview will last a few days before a cold front brings a return to cool temperatures later in the week.
Sunday will be sunny with a high near 43. Then strong southerly winds will bring an unseasonably warm air mass to the region Tuesday and Wednesday.
Monday will be mostly sunny with calm winds and a high near 57.
Daytime high temperatures will be a 'roller-coaster' this week, starting off seasonably cool on Sunday, then featuring a spring preview for a few days, before a cold front brings a return to cool temps late week. #njwx #dewx #mdwx #pawx pic.twitter.com/xozwXSSY4i

Tuesday’s temperature will reach a high near 62 and bring the chance after 4 p.m. of heavy rain showers and an isolated thunderstorm or two. The chance of precipitation is 30 percent with amounts of less than a tenth of an inch possible, according to the weather service.
Rain is more likely overnight Tuesday into Wednesday, which calls for a breezy day with a high near 63.
Showers are likely Wednesday night into Thursday before 10 a.m. Then the sun is expected to break through for a mostly sunny day with a high near 45.
But don't store away the winter gloves and snow shovels just yet. Meteorologists are being wary of calling an end to winter as they eye a possible disruption in the polar vortex in March.
