November 2003 was overall warmer and drier than normal for South Central Texas, except for parts of Lavaca, Dewitt, and Karnes Counties where heavy rains on November 16 and 17 made November wetter than normal. Extremes in weather increased dramatically in November 2003. The first freezes for the Fall of 2003 came in the mid and late part of the month. The first 5 days of November were very mild, then turned much cooler the 6th, as a cold front came through the area. The cold air was shallow and was immediately overrun by mild and moist air, making for several days of thick cloud cover. On the 7th, 8th, and 9th, daytime highs were much below normal. On the 7th, a daily record for the coolest daytime high of climate record was observed at Austin Bergstrom, Austin Mabry, and San Antonio. On these cloudy days, scattered mainly light rain affected the area. Clearing came on Monday the 10th. Clouds returned quickly the 11th, then skies cleared up to a partly cloudy day on the 12th.

On the 13th and 14th, clouds returned again, ahead of a large scale rain making weather system to the west. Ahead of this weather system, mostly cloudy days prevailed as warm and very moist air moved up from the south. Mild nights to warm days prevailed. Widely scattered showers came Sunday the 16th. Rain increased late the 16th to the night of the 16th and early morning of the 17th, over the southeast parts of South Central Texas, where heavy rains fell over parts of Lavaca, Dewitt and Karnes Counties. As the Mid November rain making weather system moved over the area on Monday the 17th, scattered showers and thunderstorms formed. Very heavy rains again fell over parts of Karnes, Dewitt, and Lavaca Counties in the morning and again in the evening hours. From November 16th to November 17th, some areas over parts of Karnes, Dewitt, and Lavaca Counties had between 3 and 5 inches of rain, with isolated amounts near 7 inches.

November 17th marked an end to the prevailing southwest winds aloft that prevailed since the early part of October and lasted to Mid November, helping to bring many mostly cloudy days to the area. On November 17th, weather systems began to come more quickly from the west and northwest, helping to bring more sunshine during the day and more extremes in weather for the rest of the month. A November that had started out in a semi wet and mostly cloudy pattern, quickly turned to a dry fall weather pattern after the 17th.

As the strong rain making Mid November weather system and its associated cold front moved rapidly east of the area, mostly clear skies and windy conditions followed during the day of Tuesday the 18th. This helped bring much drier air to the area. On November 19th sunny conditions prevailed, as cooler air filtered over the area from the north. With clear skies, the night of the 19th and early morning of the 20th had the first freeze of the fall for parts of the Texas Hill Country. Daytime highs warmed up quickly during the day of the 20th, and continued warm the 21st. The humidity returned quickly the next day on Saturday the 22nd.

The warm weather then ended quickly when a strong cold front swept through the area on Sunday November 23rd. On the 23rd, a strong cold front came across South Central Texas during the morning. Widely scattered showers formed mainly near and east of Interstate 35 in the morning and moved east of the area by the afternoon. Initially modified Pacific air came across the area from the west northwest, and was quickly replaced by colder continental polar air in the afternoon and evening. Windy conditions prevailed all day and continued into the evening hours until about 11 pm to midnight. More widespread freezing temperatures came to the area early Monday morning November 24th. Lows fell to near 20 to the mid 20s over the Texas Hill Country, to the upper 20s to mid 30s across the remainder of South Central Texas. The day of Monday November 24th was clear, with afternoon highs in the 50s.

On Tuesday the 25th, scattered high clouds moved over the area from the west, after an early morning freeze over the eastern part of South Central Texas. Afternoon highs moderated to the 60s. On the night of the 25th and morning of the 26th, clouds returned to the area, then became partly cloudy by late afternoon and around sunset. Late Wednesday night of the 26th to the early morning of Thursday the 27th, areas of fog formed between Midnight and 2 am east of an Austin to San Antonio to Pleasanton line. The fog began to break up and thin out between 4 am and 6 am as dry west winds continued to march eastward across South Central Texas. This was followed by a surge of cooler air from late morning to early and mid afternoon, as a Pacific Cold Front moved quickly southeastward over the area on Thanksgiving Day. Daytime highs warmed up ahead of the Pacific Cold front to the 70s over South Central Texas, while over the Hill Country the highs only made it to the 60s to near 70, before cooling off. Clear skies and windy conditions prevailed in wake of the cold front on Thanksgiving Day. Clear skies followed in the evening, and winds began to diminish in the night of November 27 and predawn hours of November 28th. Lows on November 28th were in the 30s. Clear skies prevailed Friday, November 28th, as highs warmed to the 60s. A cold night followed, with early morning lows a little colder on November 29th, in the 20s over the Texas Hill Country and in the mid and upper 20s to 32 over South Central Texas. On Saturday the 29th, scattered high clouds came over the area from the west and northwest, then skies became clear in the afternoon again. Afternoon highs were again in the 60s. On the last day of the month, low clouds returned to the area, as afternoon highs warmed up to 70s.
