Barry will continue to top the headlines this week as it transforms into an extratropical cyclone by midweek as it brings rain to the lower Mississippi River Valley all the way up to the Northeast. We’ll also be tracking extreme heat, a relatively dry weather pattern, and more in this week’s 4 Things to Watch.

Barry’s Tropical Remnants:

Barry is slowly moving further inland as it gradually transforms into an extratropical low pressure, which essentially means it will lose its tropical characteristics due to it moving over land. Despite this, heavy rain will continue to remain a threat this week. To start the week, the center of Barry will be located over Arkansas, bringing rounds of heavy rain and thunderstorms to the region. As the week progresses, the rain will move toward the Ohio River Valley and eventually the Northeast by Thursday. The heaviest of totals will be focused in the Mississippi River Valley, with widespread rainfall amounts of 2-6 inches. In the Ohio River Valley and Northeast, totals will generally be in the 0.5-2 inch range.

Nationwide Heat Wave:

A ridge of high pressure will build over the East Coast through midweek, drifting toward the central US while expanding across most of the nation as the weekend approaches. This will bring a heatwave featuring temperatures well about average and widespread highs in the 90s and 100s. The heat will really begin to be felt across the Northeast, especially the I-95 corridor, Tuesday into Wednesday with highs reaching the 90s. “Feels like temperatures” will even exceed the 100 degree mark across much of the Mid-Atlantic. Storms will then lead to a brief cool down late-week before the heat ramps back up just in time for the weekend. By the weekend, most of the US will be experiencing temperatures of this magnitude. The heat should then settle down for the East Coast and return to average early next week.

Drier Pattern:

With the impending ridge that will be responsible for the extreme heat across most of the nation, that sinking air due to the higher pressure will allow for dry conditions overall. This will be good news once Barry’s remnants clear the affected regions, allowing for the ground to dry out and the floods to gradually recede. On the northern periphery of this ridge across the Northern Tier, there will be a couple rounds of storms, a common occurrence to these types of ridges in the summertime. For everyone else, dry weather will win out.

Tropics Settle Down:

The tropical Atlantic basin will settle back down post-Barry — at least for this week. The National Hurricane Center did designate an area of disturbed weather over the Main Development Region of the Atlantic Ocean as Invest 93L late last week, but the chances of development diminished and thus there is no risk for tropical development in this part of the world this week.

As we get into August and September, though, we do anticipate activity to ramp up.
