Frontal passages produce precipitation
A range of precipitation types is expected to fall at the Institute over the next few days as two cold fronts pass through the area. The first of these cold fronts will pass through during the day today, meaning that this morning’s unseasonably warm air is not long for our area. People enjoying temperatures in the mid 50s°F this at the start of their day may not be pleased to discover temperatures falling through the 40s°F in the afternoon and evening. Meanwhile, rain showers will intensify and become steady overnight, possibly changing over to snow before ending tomorrow morning.
After a chilly Saturday night, precipitation will return for Sunday night and Monday. This time, the precipitation may start out as snow, but is expected to change over to a mix of snow, sleet, and rain as temperatures rise during the day on Monday. However, as this system is still several days out (and has yet to even form), it is too soon to meaningfully predict the sequence of precipitation for Monday.
