1°Outside On the Horizon: August 2024 Monthly Forecast

Matt’s full video explanation is above, but if you enjoy a written summary of the main points, you’ll find that below.  Bottom line fpr August: jetstream trough limits deep summer heat for New England….but leaves us watching the tropics.

August Weather Forecast: What to Expect

Overview of August Weather Patterns

As we kick off the first weekday of August, Danielle and I are looking at significant changes in the jet stream pattern expected to persist through at least the first half of the month. Here’s what you need to know:

  1. Jet Stream Pattern: The jet stream will maintain a heat dome across the South-Central United States, while bringing westerly winds across the northern tier of the country. This creates a broad trough over the Northeastern United States.
  2. Impact on Temperatures: The heat will persist across much of the Southern United States. However, New England and the northern tier of the country will experience more frequent incursions of cooler air with these jet stream disturbances. As a result, we expect near-normal temperatures for August in New England.
  3. Precipitation: The frequent passage of disturbances will lead to increased chances of showers and thunderstorms, contributing to above-average precipitation for New England.

Detailed Temperature and Precipitation Forecast

  • Temperature: While the majority of the country will experience above-normal temperatures, New England is forecasted to have near-normal temperatures. It’s worth noting that slight variations could push this to slightly above normal.
  • Precipitation: The pattern supports frequent thunderstorms and showers, leading to above-average precipitation. This setup also opens the door to potential coastal systems and tropical activity, particularly in the latter half of August into September.

Tropical System Watch

With high pressure dominating both over the ocean and the nation’s midsection, a weakness could develop along the eastern seaboard. This might allow tropical systems to curl northward. Therefore, we need to monitor the tropics closely as we move into late August and September.
