Graupel Saturday, possible snow Sunday – NBC Boston

0

A higher level system will be our dominant feature this weekend as we face a few rain showers/snow showers and some rumbling thunder, especially on Saturday evening in the first half of the night.

Some of these showers may contain small hail and graupel. Graupel? Yes Graupel! Graupel belongs to the frozen precipitation family and is formed by supercooled water droplets that accumulate on snowflakes as they fall from the cold upper levels of the atmosphere into a “relatively” very shallow surface layer. sweet, causing them to partially melt. They have a very distinct appearance and can be mistaken for small hail, except graupel is white and has a crunchy texture.

The threat of precipitation will be with us for the first half of the night, then we will see conditions improve. Saturday evening lows will dip into the upper 20s to 30s in the north and into the 30s in the south.

We’ll still be dealing with the upper level system on Sunday, but we’re not expecting too much precipitation except for a few rain/snow showers in the interior parts of southern New England and mostly snow showers in the northern mountains.

Clouds will be more dominant during the afternoon and a stray shower still cannot be ruled out for much of the area, but most will remain dry. Highs reach the upper 40s to 50s in the south and the 30s and 40s in the north.


A strong cold front will cross the region on Sunday evening, accompanied by a few flurries and snow showers.

Much colder air will be in place with gusty northwesterly winds by Monday morning, with wind chill readings reaching the digits and teens, which is why we’ve added an early warning stamp on our 10-day forecast!

Monday’s highs will barely reach the upper 20s with the low 30s in the north and mid 30s in the south!


The good news is that the unseasonably cold temperatures will be short-lived, with temperatures returning to seasonal levels by the middle of next week, but that comes with the threat of further rain showers as we let’s start the month of april.
