After Arthur, Heat and Humidity Build East, Then Storms

In the wake of Hurricane Arthur, beautiful weather across most of the eastern U.S. will end with the weekend.
The recent stretch of comfortable conditions that followed Arthur are due to a zone of high pressure that will slide across the mid-Atlantic on Sunday.
As this area of high pressure moves into the Atlantic on Monday, a cool, northwesterly wind will cease and swing around to the southwest. As a result, humidity levels will rise for the start of the week.
A return to typical midsummer temperatures is expected through at least Wednesday in the eastern third of the country. The core of the heat should be centered across the Carolinas where some spots may approach the century mark come Tuesday and Wednesday.

In the I-95 corridor of the Northeast, thermometers should make another run at the 90-degree mark for the second consecutive week.
New York City, Philadelphia and Washington, D.C., will have two straight days of 90 degrees Monday and Tuesday with temperatures approaching that mark on Wednesday.

In addition to the 90-degree weather, dew points in the 60s to near 70 will make for uncomfortable outdoor conditions. Those exercising or spending time outside are encouraged to hydrate frequently and find shade when possible.
A cold front lurking to the west will sag southeastward through the first half of the week. This front will serve as a focal point for heavy thunderstorms.

The western Great Lakes are forecast to get thunderstorms Sunday, some of which could be severe. On Monday, the Ohio Valley and eastern Great Lakes should receive the brunt of the stormy weather while the focus on Tuesday and Wednesday will shift to more of the Northeast and mid-Atlantic.
By the end of the week, signs point toward more comfortable conditions with lower humidity returning to the Northeast. Stormy conditions may continue in the Carolinas as the front lingers across the region.
