Dry, warm, and many sunny days summarizes June 2005. This years June contrasted greatly with June 2004, when many cloudy days and heavy rains brought floods to Central and South Central Texas. For a summary of June 2004... See June 2004 Weather Review. June 2005 was the 6th driest at Austin Bergstrom, and a tie for the 7th driest at Del Rio. For San Antonio and Austin Mabry, June 2005 was not in the top 10 driest Junes; however, it was still significantly below normal.  At Austin Mabry June 2005 tied with June 1965 for the 29th driest June of Record. At San Antonio June 2005 tied with June 1998 for the 20th driest June of Record. Several additional factors contributed to the June 2005 dryness. These factors included high evaporation rates with the high June sun on numerous sunny days, and lack of rains since the beginning of June. The dryness in June 2005 could have been more intense, if it had not been for a period of days with clouds in the area from June 5th to 13th. At Austin and San Antonio, the only day with measurable rain was June 1st, and the last day of any rain was a Trace on June 9th. A Trace of rain is less than one half of one-hundreth of an inch. At Del Rio, the last day of measurable rain, equal to or greater than one-hundreth of an inch of rain, was June 10th.

In wake of the November 2004 floods, a drier weather trend set in for Central and South Central Texas around Thanksgiving of 2004, and continued through December 2004 and the early to mid part of January 2005. In late January 2005 more rains came, and this trend continued through March 2005. Rainfall then became much drier than normal in April, after above normal rains from late January through March. In May rainfall was below normal at Austin and San Antonio. At Del Rio, May 2005 rainfall was slightly above normal. From January 1st to June 30th, 2005, rainfall for the Year was below normal at Austin, Del Rio, and San Antonio. As June 2005 began, rains came in the early morning of June 1st. As the storm track moved north, the rains began to shutoff after the 1st. From January 1st to June 30th, Austin Bergstrom has had 13.68 inches of rain, 4.08 inches below normal; Austin Mabry 13.50 inches or 3.87 inches below normal; Del Rio 6.71 inches, 2.14 inches below normal; and San Antonio 10.40 inches, 6.52 inches below normal.

Afternoon highs were moderated in the early part of June, partly due to continued soil moisture in wake of Fall 2004 and Winter 2004/2005 rains. As soils began to get drier and the subtropical high increased by Mid June, afternoon highs increased June 14 to 18, moderated some June 19 to 26, and then increased again June 27 to 30. The warmest day at most locations for the month came June 30th. As soil moisture decreased by late June, afternoon highs had more room to heat up.

Most of the rain in June 2005 fell on June 1st, and some locations had their only rain on June 1st. In the predawn hours of June 1st, the month began stormy, as a line of thunderstorms swept across the area from the north and northwest.  What began as an area and line of thunderstorms in West Texas the afternoon and evening of May 31st, became a source for rains and severe weather as June was just beginning. Wind damage from the storms was reported in Gillespie, Kerr, and Kendall Counties. The daylight hours of the 1st saw decreasing clouds and plenty of sunshine. By Friday the 3rd, isolated showers showed up over the west and north part of the area, where Del Rio picked up 0.09 inches of rain, with Kerrville 0.18 inches and Rocksprings 0.05 inches of rain. On the night of June 4th to early morning of June 5th, an area of thunderstorms moved from southwest to just south and southeast of San Antonio. This caused strong winds and scattered rains.  Winds gusted to 41 mph at San Antonio Stinson Field around Midnight.

The period of June 5th through the 12th, was one of moderate south and southeast winds, as storm systems tracked mainly north of South Central Texas. The moderate to stronger than usual southeast breezes kept temperatures moderated for a while, as Gulf of Mexico sea surface temperatures were slightly below normal near the Texas coast from June 4th to 12th. On June 10th, showers made it to Del Rio and Rocksprings and were isolated over parts of Maverick, Dimmit and Zavala Counties.

June 2005 weather began to change by Monday the 13th, as a subtropical high began to build over the area from the west. This was long predicted for 1 to 2 weeks by NCEP Medium Range Forecasts. The pattern also matched what had occurred in the previous month, from May 16th to 23rd. On Monday the 13th a thick blanket of cloud cover worked its way east over the area in the day, with sunnier and warmer conditions over the west part of the area.  A few showers in the afternoon showed up over the eastern Hill country to near San Marcos and Austin and Georgetown, then diminished in the Mid to Late Afternoon. From June 14th to 18th, rising temperatures brought some of the warmest temperatures so far in 2005, from January 1st to June. Del Rio had its first 100 degree day of the year June 16th, when the high was 101. The hottest days of the month at Del Rio was June 17th and June 30th, when the high was 102.

Once again more maritime southeast winds returned on June 19th, and conditions began to moderate again with highs in the 90s. The week of Monday June 20th to Friday June 24 brought a few mild early mornings, with lows comfortably in the 60s to near 70. By the weekend of the 25th and 26th, conditions began to change once again to warmer afternoons. Widely scattered showers made it to the east part of South Central Texas the 25th; however, most amounts were light.  By Sunday the 26th, the June subtropical high increased again, bringing more stable conditions from the west and north. Only isolated showers showed up over the extreme east and southeast part of the area Monday the 27th to Wednesday the 29th.

The last 3 days of June from the 28th to 30th brought hotter days, like what had showed up June 14th to 18th. The warmest day of the month at many locations came on June 30th. Austin reached 100 degrees and Del Rio reached 102 again, previously seen on June 17th. The warmest day of June at San Antonio was also on the 30th, with the high of 98.
