Significant/Hazardous Weather

Rain and the risk of flooding will continue into the night, as low pressure passes nearly overhead, before intensifying late over Québec. A strong cold front will end the rain, with a changeover to snow that will be uneventful in most areas. But icy roads could develop overnight, as temperatures drop below freezing.

Recreational Forecast

Mountain Forecast:

Today summits are expected to be obscured in clouds and rainy weather. Rain will continue throughout the day today. Rain could be moderate to heavy at times, especially in the afternoon and evening. A blocking warm front will set up in an east-west orientation across southern New England. This in combination with a north-south oriented cold front perpendicular and set up along the east coast will pump significant moisture and warm air from the Gulf of Mexico up into the Northeast. Highs today will be unseasonably warm and mainly in the 40s. This will cause snow to begin to melt. Rain along with snowmelt has the potential to create isolated flash flooding in ravines, as well as urban areas. Additionally, the storm will bring strong winds, which could gust up to 60 mph, further complicating conditions. These winds, along with the heavy rain, will create hazardous conditions, especially in exposed areas. As temperatures drop overnight, rain may transition to snow as the air cools below freezing. Light snow accumulation is possible over the Adirondacks, but little to no accumulation is expected in other areas. The storm system is expected to cause disruptions in both the weather and travel, with ongoing risks of flooding and high winds into the evening.

Wind At Lower Elevations:
Today, south to southeast winds near 10 mph, gusting to 25 mph. The outlook for Thursday calls for west winds increasing to 10 to 25 mph, gusting 30 to 40 mph.

Detailed Discussion

I’m sure many of you have noticed the steady rain this morning, and the warm weather. We have a storm system to thank for this warm weather. A warm front has set up in southern New England, with a cold front perpendicular along the eastern seaboard. This setup will continue to fuel the rain today as moisture and warm temperatures will continually be pulled up from the Gulf of Mexico. Today highs could reach into the upper 40s to low 50s. This warm weather might be an enjoyable break from the cold December air but it also means that snow is melting. The stored water in the snow will contribute to any runoff we see due to the excess rainfall. This storm is expected to produce 1.5 to 2.5 inches of rain but add that to snowmelt and runoff totals are much higher. This morning there is the potential for bouts of heavy rainfall. This could impact any morning commutes making it a bit slippery to travel. Many schools this morning have opted to delay or close due to the inclement weather.

Mid-morning to early afternoon we are expecting a brief break in the rain showers. Now this break won’t last forever. More rain showers return later this evening and will continue to have periods of moderate to heavy rainfall. This will occur as the low pressure system steering the storm finally begins to lift out to the north and east. Vermont will be in the best position to see the brunt of the storm with the most amount of moisture and lift heading right our way. Now what this means is that with excess water from snowmelt there is the potential for river flooding to occur today. Flash flooding however will be possible in isolated areas this morning due to localized downpours. The chance for flash flooding returns again this evening as the rain returns with another chance of heavy rainfall. Remember larger rivers take longer to respond to rainfall and therefore the crest is likely to occur later, after the majority of the rain has ended. The Northeast River Forecast Center has up to date forecasts and current river conditions, if you would like to track a river near you.

Length of the day:
8 hours and 55 minutes

Dusting off the record books on this date, December 11, 1966 was the climax of a very warm spell of weather. Burlington recording a high of 61 degrees for the third straight day, while it reached 63 in Keene, NH, and 65 in Dorset, VT. Even northern New Hampshire joined in with Berlin and 1st CT Lake at 63. Of course it didn’t last, as Waterbury, VT dropped 51 degrees, from 68 to 17, on the next day.
