Next Storm Is Rain
Posted by Chris Lambert
What a start to the weekend as an Arctic air mass sent temps to -16 in Norwood, -12 in Bedford, -9 in Plymouth, -8 on the Vineyard, and even -5 in Hyannis. Boston at Logan Airport hit 2, and the mercury dropped to -4 in Worcester. Boston and Worcester's records for the date are still safe at -4 and -8 respectively. So it wasn't quite record territory, but about as cold as it gets with many towns the coldest since January 24th, 2011. We even had Arctic sea smoke over the ocean waters this morning!
The afternoon turned out just fine as temps rose to the 20s, and even some lower to middle 30s down over the Cape/Islands. With the sunshine in place, it gave road crews a chance to complete the clean-up and get down to pavement again.
So where do we go from here? Temps quickly start dropping early this evening, but hold overnight in the 10s northwest of the city and in the 20s in Boston and along the coast. Clouds increase late tonight, and there could be a touch of freezing mist near Buzzards Bay tomorrow morning. For the rest of us, a few patches of mist or a light shower passes by Sunday afternoon, but we'll get our dry hours too with temps in the 30s to lower 40s. Outside 495, there could be pockets of freezing drizzle in the afternoon. Even when temps go above freezing, the ground is so cold, that black ice still is possible there. With that in mind, the National Weather Service has issued a freezing rain advisory from 4:00PM to Midnight Sunday for northern Worcester County, and northwestern Middlesex County in MA and Hillsborough and Cheshire County in NH.
We'll see all rain tomorrow night , through midday Monday. Most guidance points to 0.50-1.00" of rain across the area by midday Monday. In terms of roof tops and the rain... I think we'll be ok overall. Since the air was so cold during this last event, the snow was the fluffy, low density variety, meaning it doesn't weigh as much as the heavy, wet snow we get. That'll give us some wiggle room to allow the snow to absorb rain water Sunday night and Monday without causing structural damage due to overloading. If you have a huge snow drift on a part of the roof and you want to knock it down, that's fine, but generally, we should be ok. If we were talking 2-3" of rain on top of a heavy, wet snow pack, it'd be a different story.
Cold air plunges us back into a deep freeze by Monday night, and wind chill factors run below 0 all day Tuesday.
There's been talk about the Green Bay game Sunday being the coldest on record? It won't be. Don't get me wrong, it'll be cold, but the core of the Arctic air won't arrive until Monday. Kickoff temps should be near 0, as the -15 to -25 air temps hold off for 12 to 24 more hours. Could you image if it had been faster getting in? The Ice Bowl game against the Cowboys in 1967 was in the -13 to -15 range.
