Though April Showers May Come Your Way – They Bring Even More Rain in May

May 2015 is officially the wettest month ever recorded in Texas.  Texas A&M Today reports that the current deluge has broken all records for precipitation in a single month.

Figures from the Office of the State Climatologist at Texas A&M University show that the month of May has been the wettest month ever in the state’s history, averaging 7.54 inches, besting the previous record of 6.66 inches in June of 2004.

“Many parts of the state have set records for the most rainfall ever,” says John Nielsen-Gammon, professor of atmospheric sciences who also has served as State Climatologist since 2000. He says the reason is a combination of factors: an active El Niño in the Pacific Ocean which tends to bring the jet stream over Texas, a steady flow of moist air from the south that becomes unstable when it undercuts the jet stream, and a stubborn weather pattern “that just won’t go away.

“It has been one continuous storm after another for the past week to 10 days in several regions of the state.  It has rained so much that the ground just can’t soak any more moisture into it, and many creeks and rivers are above flood stage.”

The good news: Nielsen-Gammon says the stubborn pattern should begin to change in a few days, “and after this weekend, we should enter a period of more normal conditions.  Spring is usually wet, but not this wet.”

The state’s wettest area has been from the Dallas-Fort Worth area to the Red River, parts of which have received more than 20 inches of rain this month.

The Houston area was not hit “that hard until the past few days, but then heavy rains came in waves and areas around Sugarland have received more than 17.50 inches of rain.  The area around San Marcos has received heavy flooding, with more than 18 inches of rain this month,” Nielsen-Gammon adds.
