August Weather: 'There will be a few noticeable differences'


Dr. Doug Gillham
Meteorologist, PhD

Monday, July 31, 2017, 11:16 - Will August bring a continuation of unusually hot weather continue across the Intermountain West and northern High Plains? Will the East continue to see a lack of persistent heat during August? The answers are ahead in The Weather Network’s forecast for the month of August.

July: Lack of Persisent Heat

First, a quick look back at the month of July. The map below shows temperature anomalies (difference from normal) for the month, with the various shades of orange and red representing warmer than normal temperatures during July. This highlights the summer heat which has been most persistent across the western half of the country. Meanwhile, the east has seen a lack of persisent heat so far this summer, though the mid-Atlantic region has been warmer than normal.

Early August will feature a continuation of the pattern that has dominated this summer. Mid-summer heat will make a brief appearance into the Great Lakes and Northeast, but late in the week and into the weekend another strong cold front will track across the region and bring a return to below seasonal temperatures for the first weekend of August. 

Looking ahead to the rest of the month, we do not expect any major changes to the overall pattern, but there will be a few noticeable differences.

Mid-August: Tracking the heat

As we head towards mid and late August, it looks like the eastern third of the country will see a period of hot weather that will be more long-lasting than what we saw during July. However, hot weather will not completely take over the pattern as periods of cooler weather are still expected at time. 

The most persistent heat will continue to be across the Intermountain West, but coastal areas and the dessert southwest will continue to see near to slightly below seasonal temperatures.

The central part of the country is expected to be near to slightly above seasonal, but not as warm as what we saw during July. The focus of the shots of cooler weather is expected to shift further west as the month progresses, so instead of being aimed just at the Great Lakes and Northeast, we expect that the Northern Plains and Upper Midwest will also see periods of cooler weather.

Much of the country has received near to above amounts of rain during the summer and this pattern is expected to continue through August. However, the Northern Plains have experienced worsening drought conditions this summer and widespread relief is not expected for this region during August. While August should bring more rain than June and July, most of the region (especially the west) will continue to be on the dry side of normal.
