The weather pattern that has produced a heat wave in the Pacific Northwest has brought cooler temperatures and rain to northeast Kansas.

Adam Jones, meteorologist for the National Weather Service office in Topeka, said the dome of high pressure over the Western states that is responsible for that area’s heat wave has also allowed cooler, drier air to sweep into the Midwest.

“That’s exactly what’s causing it,” he said. “It looks like the high-pressure dome will persist through the next week, so we’ll continue to see daytime highs in the upper 80s or low 90s. That’s not bad for this time of year.”

Sunday’s high will be even cooler with an afternoon forecast in the upper 70s, Jones said.

Some rainfall has accompanied the local weather pattern. Jones said the National Weather Service station at the Lawrence airport recorded half an inch of rain from midnight to about 10 a.m. Saturday. That brings the total rainfall in July thus far to about 0.6 inches; the average for this point in July is 1.3 inches. Jones said Lawrence could receive from 0.8 inches to an inch of rain Saturday evening and Sunday morning, and more showers are possible Monday and late Wednesday or Thursday.

Lawrence has officially received 23.76 inches of rain for the year, or 4.52 more than average, Jones said.
