Tropical Storm Harvey Means High Pressure, High Heat In Phoenix
As Hurricane Harvey churned off the Gulf crashing into Texas, temperatures ahead of it dropped a full ten degrees in Houston.
Conversely, the mercury pushed toward a record high of 111 degrees here in Phoenix and record highs across the Southwest.
Typically, on August 27th, the high in central Phoenix tops out just over the century mark, while monsoons continue threatening bursts of much needed rain.
But, meteorologist Ken Waters with the National Weather Service says that's not happening so long as — now downgraded — Tropical Storm Harvey hangs heavy over southeast Texas, refusing to move east.
“We’re indirectly related to this," he explained while pointing out two distinct circles on a weather map.
The moving map showed the circles side-by-side, churning in opposite directions.
He pointed to the portion over the Southwest's Four Corners region, adding, "The high pressure that’s sitting over us right now providing these hot temperatures, that’s kind of keeping that storm from moving out of Texas.”
He explained our neighbors in the great state of Texas are caught in the middle of what he called a "Teeter-Totter Effect."
On one end of the teeter-totter, he said, "we have high pressure over the desert Southwest creating flow from the west central U.S.," and on the other end, "you have high pressure out over the Gulf of Mexico and the Atlantic."
Tropical Storm Harvey sits right in the middle, Waters said, "and, it's basically trapped, where both sides have about the same weight and keeps that storm more or less in the same location."
By midday Monday, our high pressure system was colliding into Harvey's low pressure pattern just over the Texas panhandle, creating an imaginary wall.
"So, it's keeping us dry and it means that moisture from (Tropical Storm Harvey) is not going to make it into the Southwest."
At least, he said, not until Tropical Storm Harvey releases its grip on the Gulf Coast and moves on sometime around Thursday.
