The first significant round of cold continues to settle in Monday over the Great Lakes, with the coldest part of the air mass over the Northeast later Monday into Tuesday.

Stratospheric Warming – “Strat Warm”
While you may not hear much of this on TV or in normal weather websites, stratospheric warming can have a large impact on the weather in the United States. Last year, it was responsible for the intense snow, ice and cold felt in Texas and many parts of the south. The stratosphere is roughly 10-50km …
A Look Ahead – Waiting for the Cold
The majority of this week is spent waiting for the colder air mass which is scheduled to arrive this weekend. There are a few discrepancies on timing and initial depth but we’ll start to see some of those details come into light as we get closer. Overall Monday and Tuesday are warm days – probably …
The Week Ahead – First Real Cold Punch Arrives
A cold front crossed the region early this morning, prompting a slow and gradual cool down during the day and continues into the overnight. The secondary front, which is bringing our first truly cold air mass, arrives on Wednesday. The core of the cold settles in for Wednesday night, which will be our coldest night …

Long Term Views – Ups/Downs of November
This was our season changing week with not one, but two coastal lows to impact the east coast. The tropics look all but shut-off (minus the invest of what impacted us Tuesday/Wednesday), and we have our first cold shot of the season next week. Though we’ll be at the mercy of the current pattern of …
Ice Accretion Forecasts
I should probably preface this blog with the fact I’m not forecasting an ice storm – yes there are some models throwing out snow next week but we’ll save that for tomorrow’s discussion! Yesterday, I attended a (virtual) winter weather workshop with the National Weather Service in Gray, ME for their annual meteorologist gathering ahead …

We’ve been eyeing the change of the calendar as the shifting point from fall-like weather to cooler, more favorable weather. The past few weeks have been fairly cyclical with two cold fronts a week, some sporadic rain and showers, but we’re seeing that come to an end this week with likely the season changing systems …

The Week Ahead – Cool Start, Then Back To “Fall”
We’re starting off the week with a raw and cloudy forecast, even a few showers (or flurries, depending on elevation) sprinkled in there as well. This cold punch isn’t expected to last long, but tonight will be the coldest night, despite some cloud cover and stray light precipitation. Elevations above 3,000 feet should see temperatures …

Brief Cold Punch Settles in Tonight through Tuesday AM
The cold front came through with heavy rain and even some thunderstorms last night, but the cooler air slowly sets in now with the first proper cold shot of the season. An upper-level low overhead reinforces clouds and even rain/snow showers for Monday and Tuesday, allowing that cold air to truly settle in. Temperatures drop …

Long Term Views – A Few Cold Shots
For the past couple of weeks, we’ve been highlighting the necessity of the tropics to shut down before we can get cold shots in and try to sustain it for any reasonable amount of time. There’s one disturbance in the middle of the Atlantic meandering around with a 0% chance of formation in the next …
