In a winter that began sunny and dry, only to turn cloudier in January and rainier by late January, this trend continued on for most of February 2005. According to data compiled by the National Climatic Data Center, Texas statewide precipitation for February 2005 was the 20th wettest February of record, 1895 to 2005. The active southern stream westerlies from the Pacific brought many and frequent upper air disturbances from the west in February. This was influenced by pressure patterns over the Pacific, with a blocking high south of Alaska near the West Coast of North America, that diverted more energy to the southern jet stream. By Late February, some weak influence from the Mid Pacific Warm and Weak El Nino Event began to come into play. Although many Februarys in the past have brought cloudier weather, they also brought temperature extremes. February 2005 was one of those Februarys that did not bring vast extremes from cold to warm or from warm to cold. Many cloudy days limited daytime warming and overnight cooling. Although the month began very cold, milder weather followed and nighttime cloudiness and moisture kept overnight lows higher. In addition to many cloudy days, there were many days with fog. As a result, February 2005 could be summarized into a mostly cloudy, rainy, mild, and more foggy than usual month for February.

The last few days of January 2005 and first 2 days of February 2005 brought much below normal temperatures to parts of Central and South Central Texas. The high level cloudiness that lingered February 3rd and 4th, and even during most of the day on the 5th, limited any rapid warming late in the 1st week of February. Rainfall wise, the tide changed from dry winter weather to wet winter weather in late January 2005, and continued through February. On the weekend of January the 29th and 30th colder conditions, along with rain came, and it continued to get colder the 31st of January, and through February 1st. Highs January 31st were mostly in the 40s, with lower 50s over the west part of the area, where the depth of cold air was shallower. Stronger north and northeast winds the 31st, added to the chill, along with periods of rain. Some of the rain activity in the day became convective at times, with periods of showers and occasional thunder at some spots.

As February 1st came, cold temperatures continued and a wintry mix of precipitation developed in the morning over Val Verde and Edwards Counties, and continued into part of the afternoon. The wintry mix ended in the early afternoon in Val Verde County; however, it continued in Edwards County for part of the afternoon, and spread east to the northern part of the Texas Hill Country. Over the rest of South Central Texas occasional rain was observed. With all the precipitation and additional surge of cold air, colder conditions prevailed the 1st. Daytime temperatures were in the 30s to near 40 in areas receiving a mix of rain and wintry precipitation, while from Eagle Pass to San Antonio to Austin and east, they were near 40 to lower 40s in the day with occasional rain and showers. Snow was observed from around Pandale to Juno in Val Verde County; however, it did not stick on the ground. Over the northeast part of Val Verde County, the snowfall increased and this continued to northern parts of Edwards County. At Loma Alta in northeast Val Verde County around 1 and 1/2 to 2 inches of snow fell. The snow over Val Verde County fell in the morning and early afternoon. The snow stayed on the ground around Loma Alta until the evening. Further east, periods of snow fell over northern Edwards County in the late morning and afternoon. The most snow was observed at 12 miles northeast of Rockspirngs, with 6 inches of snow, while at Rocksprings 3 inches of snow was seen. At Rocksprings in Edwards County, snow stayed on the ground through the day and night, then melted by the next morning. In northwest Edwards County 2 to 3 inches of snow fell.

Further south over Del Rio, the rain was mixed with sleet and pea size hail. There was one report east of Del Rio Airport, between 1030 and 1100 AM, of a brief flurry of snow flakes mixed in with the rain, sleet and thunder. As the precipitation moved east in the afternoon and evening a mix of sleet and rain was observed over parts of the hill country. Snow was observed in the Junction area south to the northern part of Kerr County. Snow was reported about 30 to 35 miles northwest of Kerrville. In Kerrville sleet and snow grains were observed in the afternoon. Rain, showers and isolated thunderstorms moved over San Antonio in the late afternoon just before sunset and continued east to the Austin Area in the early evening.

Cloud cover continued the 2nd, keeping highs in the 40s, with lower 50s in an area from Hondo to Uvalde, and extending south to Cotulla and west to the Rio Grande, south of Del Rio. On the 3rd and 4th, clouds lingered, and even stayed around most of the day on the 5th. The first 5 days of February showed the average temperature around 6 to 8 degrees below normal, mainly due to the low daytime highs in the wet winter weather pattern and considerable cloudiness. Rain came late during the day of the 5th and night of the 5th to the morning of the 6th. Conditions warmed up some by the afternoon of the 6th, the 1st day of near to slightly above normal afternoon highs in February 2005.

Rain and showers returned on the 7th. Brief clearing showed up in the afternoon, with partly cloudy conditions over the hill country. On the 8th clouds and patchy fog prevailed with occasional light rain. On the 9th, the warmest part of the day came in the pre dawn hours to shortly after sunrise, ahead of a cold front that moved through just after sunrise. Temperatures slowly fell during the day under cloudy skies. Several cloudy and cool days followed, then skies cleared up the 13th beginning a stretch of dry weather that lasted through the 16th. The warmest part of the month was the 14th and 15th.
