Bethlehem Pennsylvania Weather

While the start of the week could bring a few passing showers and thunderstorms with the establishment of cold air, we should take a close look at the track and strength of an approaching storm. If a strong clipper system has a chance of a period of steady snow or rain on Thursday, it could become a major storm if it moves far enough south and develops again before leaving on Thursday. A decent amount of drenching is expected, with locally high amounts likely to occur in the late afternoon and early evening hours of Thursday and Friday, but if this does not happen, there will likely be no major rainfall for the rest of this week or even the next few days.

However, the dry weather of the past week and a half does not mean that there will be any flooding due to the lack of moisture in the air.

Different types of precipitation are observed every day, not taking into account the quantities of traces, but the most common form of rain and snow falls on the same day. This is the total amount of snow Allentown and Bethlehem usually get, as well as how many days it snowed. There are also days when there is usually deep snow accumulating in the ground in the city. Based on this classification, most of the usual forms of rainfall in Bethlehem during the year are rain alone, according to the National Weather Service.

Given the humidity, the temperature feels cold for half the year, with the chance of rain or snow. The temperature will remain below 30 degrees during the day for the time of year, but above 30 degrees at night, the NWS said.

Allentown and Bethlehem have at least an inch of snow on the ground on about a third of winter days, and February's snow ranges from 16 inches, the heaviest snowfall of the year, to 2.7 inches, the lightest this year. The snowfall in Allentown and Lehem has left only a few inches on the ground, according to the NWS.
