Summer Solstice Won't Feel Like Summer in Some Parts of the U.S.

World's First Chief Heat Officer's Tips

Summer officially arrived Thursday at 6:07 a.m. EDT, but will the weather feel like summer where you live?

A slow-moving area of low pressure will slide eastward in the Midwest on Thursday. This system will help to bring an end to the rainfall in Texas and keep temperatures cooler than average in other parts of the country.

In the West, an upper-level ridge of high pressure will bring mainly dry and hot conditions, except in parts of the Northwest into the northern Rockies, where a disturbance will bring wet weather.

Where It Will Feel Like Spring

Most of the northern tier states will see temperatures near or slightly cooler than average.

Cooler-than-average temperatures associated with the area of low pressure pushing through the Midwest will be found from portions of the central and northern Plains into the Midwest.

High temperatures there will be mainly in the 70s, although a few spots may not climb out of the 60s. Highs in this range are the average highs there in early May.

Areas farther east from the Ohio Valley into the Northeast will generally have highs in the 70s and 80s, near average for this time of year.

However, highs may run a few degrees above average along the Northeast coast, as well as in parts of North Dakota and Minnesota.

The Northwest into the northern Rockies will also see pleasant temperatures.

High temperatures from the coast into the northern Rockies will predominantly be in the 70s and 80s.

Where It Will Feel Like Summer

A southwesterly flow will result in hot, humid conditions for much of the Southeast on Thursday.

Highs in the 90s are expected, along with dew points in the upper 60s and 70s. The higher dew points will make it feel even hotter, with feels-like temperatures ranging from the mid-90s to around 105 degrees.

The combination of heat and humidity may cause heat stress during outdoor activities, especially along the Southeast coast, where heat index values will likely be above 100 degrees. A heat advisory has been issued for this reason for much of the coasts of North Carolina and South Carolina.

Some areas from the Tennessee Valley into the lower Mississippi Valley will be the exception in the South. Clouds, rain and thunderstorms will bring slightly cooler conditions here.

Another area of the country that will feel like summer will be the Southwest.

High pressure will build across the region late this week and raise temperatures quickly. High temperatures will be 5 to 15 degrees warmer than average for much of Arizona, Utah, Nevada, western Colorado, western New Mexico as well as eastern and northern California on Thursday.

Excessive heat warnings and watches have been issued by the National Weather Service for portions of California, southern Nevada and Arizona, where highs are expected to soar above 110 degrees. Heat exhaustion and heat stroke become concerns with temperatures this high over an extended period of time.

Heat advisories have also been posted for parts of northern California and west Texas.

In addition, Death Valley, a place known for extreme heat, may reach 120 degrees for the first time this year on Thursday.
