- Above-average hot conditions are expected from the Gulf Coast in the southwest and also in the extreme north.
- The southwest is most likely to be above average.
- Parts of the Mid-Atlantic, Central Plains and California are more likely to have a cooler-than-average month.
July temperatures could be a continuation of what we saw in June, with warmer-than-average conditions in the Southwest and near-average or cooler temperatures in the central United States, according to an updated forecast released Friday by The Weather Company, a IBM company, was released. and atmospheric G2.
An unusually warm July is forecast for the southwest. Temperatures in the South West are expected to be significantly higher than usual in July. This is because we expect the split flow jet stream pattern to continue from June, with a high pressure heat dome forming over parts of the Southwest.
It can be hot even near the Canadian border. Above-average temperatures are also expected in parts of the upper Midwest and Great Lakes to northern New England.
In parts of the west, central US and mid-Atlantic, conditions could be slightly cooler than average. Parts of California, especially near the coast, could get cooler in July. Our outlook also suggests that the Central Plains and Mid-Atlantic region from southern Pennsylvania to North Carolina could also be slightly cooler than usual in July.
In the central plains, a reason for this cooler July could also be a wetter July. As long as the thunderstorms are not destructive or bring too much precipitation, this would be good news given the severe to extraordinary drought.
This outlook is subject to a degree of uncertainty. The emergence of a negative NAO blocking pattern could cause warmer-than-average conditions to shift further north. There is also uncertainty as to where within the split pattern, which is expected to last through mid-July, the most unusual temperatures will occur.
“There’s no reason to expect massive changes in the temperature pattern in July, but getting the precise details is clearly the trickier part,” said Dr. Todd Crawford, Vice President of Meteorology at Atmospheric G2 and author of the Outlook.
