The Heat Trend Shifts Around
Across the mid-section of the country, we have been dealing with a stubborn weather pattern called a High Pressure Ridge. And while normally, a high pressure system is a good thing, as it brings in mostly sunny skies. But in the Summer time, it can keep intense heat trapped underneath it.
The Jet Stream, the river of air aloft that steers the storms around the planet, has had to go up and over the High Pressure Ridge. The path of storms has been to form at the top of the ridge and ride down it, as they have been doing the past few days; from Minnesota to Tennessee. This ridge is rather large and extends through much of the atmosphere, hence the jetstream has been impacted. But over the next few days, the ridge will flatten out and some relief will be coming around. Already, we will be noticing some of the heat advisories and excessive heat warnings will be coming down after today, across the Central Plains.
Today’s (Tuesday) high temps, have reached into the 80s and 90s, as far north as the Canadian border. With the mid-section of the nation, for places such as Kansas, Missouri, Oklahoma and Arkansas, the high humidity made it feel as though those highs were into the 100s. Heat advisories extended down into the Southeast; from Arkansas to Georgia.
But over time, the next week and a half out, the heat will press away from the Central Plains, but be pushed deep down, into the Deep South. Temps will trend well above average in states such as Georgia, Florida, South Carolina and Alabama. Meanwhile, the western third of the country, from Montana to Arizona, will see cooler conditions come around.
Looking even further out, the trend in temperatures doesn’t change all that much. The Southeast still sees steamy hot conditions, while the western third of the country, this time from Montana to Utah, sees cooler conditions. The Northern Plains begin to warm up again, a little above seasonal averages. While the Northeast trends seasonal for the next two weeks.
