After the long spell of cloudy weather in February, more sunshine and brighter days came in March of 2005. The first 6 days of March 2005 was like a carry over of the cloudy trends from February 2005, with mostly cloudy skies, rain, showers and a few thunderstorms. A line of thunderstorms and associated cold front on the morning and afternoon of Monday the 7th was quickly followed by clearing skies and drier conditions in the afternoon and evening of the 7th. Thereafter, from March 8th to the March 31st, a period of more sunny days began, breaking the trend of mostly cloudy weather that started in late January. Several severe weather events in March 2005 came on Monday the 7th; Saturday the 19th; Friday evening the 25th; Saturday the 26th; and Thursday the 31st.

Extremes in temperature increased more in March of 2005 from cold to warm and warm to cold. Some of the coolest weather since late January and early February came the morning of March 17th, after several surges of cold air moved over the area on the 14th and 15th. This caused freezing temperatures over the hill country, and adjacent parts of Central Texas. The warmest weather since October came on the 13th, when the high reached the upper 80s to lower 90s. In the first quarter of 2005, unlike 2004, temperatures have been able to warm up faster so far. Conditions warmed to the 80s Friday the 25th, ahead of a strong late March cold front that came Saturday the 26th. This brought not only severe weather with the cold front, also rain, showers and thunderstorms in wake of the cold front Saturday night. After morning lows in the 30s to near 40 on Monday March 28th, warm weather ended the month, with highs on the 30th almost as warm as they were March 13th. On March 31st, a big variety of weather came. The day began with brief patchy fog, turning to clear skies in the morning and mostly sunny and warm by the afternoon. The day then changed in the late afternoon and early evening, with a line of widely scattered thunderstorms over the east half of South Central Texas, developing over parts of the hill country and moving in from the northwest from the very late part of the afternoon through the evening hours. These thunderstorms brought strong winds and hail. Much cooler and windy conditions followed as a strong cold front moved across the area. March 2005 ended up cooler and wetter than normal.

March 2005 began with partly cloudy skies, only to get cloudy the 2nd, like in February. The cloudy February 2005 like weather continued through the 1st weekend of March, the 5th and 6th. Rain, showers and a few thunderstorms also came the 5th and 6th. On Monday the 7th, a line of thunderstorms came in from the north, causing high winds and hail. Reports of hail and high winds came from parts of the hill country to Austin and San Antonio and east to parts of Lavaca and Fayette Counties. Heavy rains developed over the southeast and east part of South Central Texas in the afternoon. Skies cleared from the west in the afternoon and evening. From March 8th to the 31st, a period of more sunny days began, breaking the trend of mostly cloudy weather that started in late January.

After a quick warm-up on the 8th and 9th, cooler conditions came late in the day of the 9th with a dry cold front. Sunny and pleasant days prevailed the 10th through the 14th. The warmest day overall for the month came on Sunday the 13th. Highs rose to the mid and upper 80s to low 90s. While it was the warmest day of the month for most places, including Austin, Del Rio and San Antonio, northern parts of the hill country had highs in the 70s, where a cold front had all ready passed to the south. Highs at Austin were reached around noon to the early afternoon, then fell in wake of the cold front. As the cold front continued south cooler conditions came the night of the 13th and morning of the 14th in wake of the cold front. Skies turned cloudy again on the 15th, when a strong cold front came through the area, bringing a surge over very cold air across the area from the north and northeast, that had settled over the Midwest the weekend of the 12th and 13th. This set up unseasonably cool weather through the 17th. The coolest temperatures of the month came in the early morning of the 17th, when a freeze occurred over the Texas Hill Country and adjacent parts of Central Texas. Conditions warmed up the 18th to the 20th. A line of thunderstorms came from the northwest again in the early morning of the 21st, then moved east as drier air settled over the area late in the day, in wake of a Pacific Cold Front. This set up sunny days for the 22nd to the 24th.

March 25th began mostly sunny and warm, then thunderstorms formed in the late afternoon north of Edwards and Real Counties. These storms increased in strength and turned to the east and southeast toward the eastern hill country and Austin. Large hail and damaging wind accompanied these thunderstorms. As the storms moved east by midnight, a new round of showers and thunderstorms formed after midnight and toward the morning north of Val Verde County. These thunderstorms affected the Del Rio area in the early morning, and then moved east across South Central Texas during the day of Saturday the 26th. Cooler conditions followed in the afternoon and evening of the 26th, in wake of a cold front, along with a 3rd round of rain, showers and thunderstorms. As this final wave of precipitation cleared the area, skies cleared up in the morning of the 27th to become mostly clear by the afternoon. Cool early morning lows followed the morning of the 28th, with lows in the 30s across the hill country to the upper 30s and lower 40s over South Central Texas. Dry conditions prevailed the 28th, and then more clouds came the 29th and 30th. On the last day of the month a variety of weather came. Patchy early morning fog gave way to clear skies after sunrise, to sunny and warm conditions by afternoon. In the late afternoon and evening a line of widely scattered thunderstorms formed over the east half of South Central Texas. These storms moved quickly out of the area, as a cold front followed bring windy and much cooler conditions.
