During June, many portions of Texas (10 out of 19 first order stations) experienced below-normal temperatures. The monthly mean temperature in Lubbock was 3.2 degrees below average. Only three temperature records were set or tied, with two of these occurring in Midland, and only three stations reached 100 degrees (Del Rio, El Paso, and Midland). Many parts of the state also received above-normal precipitation (11 out of 19 first order stations). El Paso had the greatest positive departure with 366% of their normal rainfall amount, and Lubbock received the most precipitation with 8.48 inches.

June began with warm temperatures for much of the state. On the 2nd, a cold front extending from a low pressure system in the Midwest moved into Texas. This front stalled in the middle of the state before moving through on the 6th, triggering showers and thunderstorms, and lowering temperatures into the 80's during this time period. On the 4th, a tornado was reported near Weatherford, and portions of North Central Texas experienced flooding. Temperatures quickly warmed back into the 90's for much of the state on the 7th and 8th. This, combined with moist air from the Gulf of Mexico, contributed to the formation of more showers and thunderstorms from the 9th to the 11th.

On the 13th, a cold front from the northwest moved just slightly into Texas, bringing precipitation to the western and central parts of the state. On the 16th, another cold front moved into the Panhandle and stalled, dropping temperatures into the upper 60's and 70's. On the 17th, Amarillo recorded a high temperature of only 66 degrees, and on the 18th, Midland set a record low maximum temperature when they recorded a high of 72 degrees. This front also brought more rain to the western and central portions of Texas. Heavy rains and flooding occurred on the 18th in parts of Val Verde and Edwards counties.

Temperatures once again reached into the 90's for most of the state on the 20th, and remained there for the rest of the month. Two cold fronts reached the Red River area on the 20th to the 21st and the 26th to the 29th. However, they had little effect on temperatures and precipitation as both fronts stalled in North Texas.

Agricultural Weather Highlights

The first days of June brought severe weather to West Texas destroying many crops, some of which could not be replanted. Cantaloupe and cotton crops were not expected to be replanted. Extension director Charles Neeb of Fort Stockton said the drought is still going strong. "The counties in the west are extremely dry. Even with light showers, we don't expect any real rain until September or August." The northern region, according to Extension director Randy Upshaw of Dallas, received up to four inches of rain which put the region over the million dollar mark in crop potential. "We will be able to get another cut of hay this season," Upshaw mentioned. "That is usually normal for this time of year, but we haven't seen it happen in a few years because of drought." The Rolling Plains also benefited from the first week's rains. The grasshopper populations were expected to be reduced from those rains.

By mid-June, the apple crop was suffering because it didn't receive enough chilling hours over the winter. "In order for apples to bloom," Extension agent Logan Boswell of Alpine said," they need 400 chilling hours from October to March." This year's crop received only 300 chilling hours. The lack of chilling hours causes blooms to become weak and light and results in improper leaf growth. Another problem with the apple crop is the potential of fire blight which is a bacterial problem affecting apples and pears, according to Extension horticulturist Dr. Larry Stein of Uvalde. "Some growers used Dormex which substitutes for about 200 chilling hours," he said. "Those who did were very pleased with the results, and those who didn't wish they had." The Rolling Plains received even more rain ranging from one-half inch to seven inches. District Extension director Galen Chandler of Vernon said," The mid-June rainfall was greatly needed, and the cooler-than-normal temperatures have been helpful." He also stated that range and pasture conditions have improved greatly within the past two weeks.

A successful watermelon harvest was apparent by the end of June. Extension horticulturist Dr. Larry Stein of Uvalde said Texas growers planted 35,000 acres of watermelons this year, ranking first in national production. The South Plains have also benefited from scattered showers. "Irrigated cotton is progressing well," district Extension director Jett Major of Lubbock stated. "Peanuts are flowering, and early planted fields are pegging. Corn is tasseling with the more mature fields beginning to silk." According to Scott Durham, district Extension Director in San Angelo, parts of West Central Texas received up to five inches of rain, and the pastures were starting to recover with good grass growth and the wheat harvest had been completed. "Livestock are doing better," he said. "Less feed is being used but tank water is still too low."

Monthly Weather Outlook for June 2000

From the Climate Prediction Center, the 30-day outlook for the month of July indicates 0-5% above the normal 33% probability of above-normal temperatures for the area north of an arc from just northwest of Big Bend to Port Arthur. Between the area south of this line and north of a line from Del Rio to Victoria, there is a 5-10% greater than normal probability of above average temperatures. The portion of the state south of this area has a 10-20% greater-than-normal probability of above-average temperatures.

Climatologists are forecasting 0-5% greater-than-normal probability of above-average precipitation for the area west of a line extending from Amarillo straight south to the Texas-Mexico border. The rest of the state is predicted to have normal rainfall amounts for July.

Past Weather Events in July
