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: warmth turns up a notch in July.
Overview
The weather pattern for July starts where we left off in the latter half of June. The jet stream, the fast river of air that steers storms and separates cool air from warm air, will be close to New England and the Northern tier of the United States for the first half of the month. This brings several disturbances and cold fronts, providing periods of relief after thunderstorms. Then, heat is likely to expand into New England more noticeably in the second half of the month.
First Half of July
- Jet Stream: Positioned close to New England, bringing frequent disturbances and cold fronts.
- Temperatures: Seasonable to slightly above seasonable norms. Expect highs similar to recent weather.
- Precipitation: Increased chances of showers and thunderstorms, especially in southern New England. Frequent storms will continue from the Mid-Atlantic to New England and the Upper Midwest.
Mid-Month Changes
- Jet Stream Shift: By mid-July, the jet stream will start to move northward.
- Heat Dome: This shift allows the dome of heat, which caused temperatures to soar in June, to move in. This should bring significantly warmer conditions in the second half of the month.
Second Half of July
- Temperatures: Expect a notable increase, with highs above the normal average of 82 degrees in Boston.
- Precipitation: While the first half will likely be wetter, the second half may see drier conditions if the heat dome fully establishes itself.
Overall
- Temperature Outlook: Warmer than normal for the entire month.
- Precipitation Outlook: Above normal precipitation in southern New England, with closer to normal levels in the north.
