Drought continued at month's end. However, it was not as severe as was the case earlier in the year. The amount of precipitation deficit was highly variable in the area. Shreveport's 21 percent deficit for 2006 thus far was near Tyler's of 19 percent; Longview's deficit was nearly 40 percent, Fort Worth's 18 percent, while College Station reported a 20 percent surplus. The thirty-day outlook for November 2006 called for below normal temperatures and above normal precipitation.
The week October 29-November 4 saw temperatures about 4 degrees below normal, and rainfall about 75 percent of normal. The week began warm, but a cold front and storm system on the 1st brought the week's rain and colder temperatures during its last half. The week's average temperature was 57.9 deg., and rainfall was 0.82 inch. This was 1.8 deg. Cooler than the previous week. Compared with the same week in 2005, the week was 6.2 deg. Cooler, and 0.28 inch drier.
The week November 5-11 saw temperatures about 4 degrees above normal, and rainfall about 200 percent of normal. A strong storm system crossing on the 6th brought heavy rainfall to the region and severe weather. It was followed by a sharp warm-up as upper air high pressure moved over the region. Strong winds blew between the 7th and 9th ahead of another cold front on the 10th. High temperature records were reached on the 9th. The week's average temperature was 64.6 deg., and rainfall was 2.10 inches. This was 6.7 deg. Warmer than the previous week. Compared with the same week in 2005, the week was 8.1 deg. Cooler, and rain did not fall in 2005.
The week November 12-18 saw temperatures about 3 degrees below normal, and rainfall about 5 percent of normal. Cold air early in the week was replaced by Tropical Maritime air on the 13th and 14th. On the 15th, a strong cold front and storm system crossed with little rain but very strong winds. Tyler clocked a peak gust of 47 mph that afternoon. Cold air followed, with much of the area experiencing a light freeze on the morning of the 17th. The week's average temperature was 54.8 deg., and rainfall was 0.05 inch. The week was 9.8 deg. Cooler than the previous week. Compared with the same week in 2005, the week was 2.9 deg. Cooler, and 0.02 inch wetter.
The week November 19-25 saw near normal temperatures and no rainfall. The week began cold and ended warm. The season's first freeze occurred on the 21st, ending a 241-day growing season which had begun on March 24. As Tropical Maritime air returned on the 22nd, dense fog shrouded much of the area on the mornings of the 23rd, 24th, 25th, and 26th. The week's average temperature was 54.4 deg., 0.4 deg. Cooler than the previous week. Compared with the same week in 2005, the week was 1.3 deg. Cooler and 0.03 inch drier.
Tropical Maritime air covered the area until an Arctic cold front arrived early on the 30th. This resulted in temperatures running up to 15 degrees above normal until the 30th. A crossing disturbance on the 28th brought rain, and additional rain and thunderstorms accompanied the Arctic front. The front brought the coldest weather of the season thus far, and resulted in sleet and freezing rain mixed with rain generally north of a Terrell-Atlanta line. Afternoon temperatures on the 30th were up to 45 degrees colder than on the previous day.
