14-day Pattern Predictions: November 11-25, 2024

Earlier today, Matt Noyes delivered a mild and delightful forecast for giving thanks to our Veterans.  Now, in Pattern Predictions, he turns to the coming two weeks.  There’s no question when you watch Pattern Predictions this week, you can tell the jet stream is getting more energized.  In fact, Matt points out one day he believes will have an impact on cross country flights because the wind aloft is so strong!  Meanwhile, how will all of this impact the chance of precipitation and temperature forecasts you find in our Noyes’ 1DegreeOutside Weather app?  Matt answers that and more in the video!

Jet Stream Patterns and Temperature Trends

As has been the case lately, the jet stream will dip into the Northeast multiple times in the coming two weeks, creating troughs that draws bouts of cool air from Canada, but not intense cold. The temperature spike in the 60s today will be brief, with highs leveling off closer to seasonal norms as we move through the month. While temperatures may trend slightly above average in some periods, they’re expected to remain moderate overall, without the 70s or record-setting highs we saw earlier this November.

Rain and Shower Chances

As the jet stream digs south, it will direct much of its precipitation to the nation’s midsection, with limited moisture reaching New England. Here’s how it breaks down:

  • Late This Week: A storm system developing over Atlantic Canada may bring some light showers to New England on Friday, along with gusty northern winds. At this point it doesn’t look like much impact, but Matt encourages keeping track with our Insights videos over the course of the week.
  • Sunday into Monday: A fast-moving “jet streak” – an accelerated area within the jet stream – could bring a round of showers to our region. There’s potential for the timing of these showers to shift, possibly arriving late Sunday or Monday, so stay tuned for updates on the app.
  • Next Week: Showers are likely to reappear mid to late next week as the jet stream potentially phases with southern moisture. However, New England will see lighter precipitation compared to the heavier rainfall anticipated in the nation’s midsection.

Potential Tropical Storm Development

In the tropics, conditions have largely calmed, though there will be an area of interest near Central America to watch for potential development by the weekend.
