by Robert K. Peters, Ph.D. - National Weather Service Cooperating Observer

Severe thunderstorms caused hail damage in the Tyler area on the 5th. As is typical in late-Winter, there were numerous fast-moving storm systems especially during the latter half of the month. Compared with February 2007, the month was 2.7 deg. Warmer, and 2.51 inches wetter. Year-to-date rainfall through month's end was 4.20 inches less in 2008 than in 2007. The thirty-day outlook for February 2008 had called for above normal temperatures and below normal precipitation. The week January 27-February 2 saw near normal temperatures, and about 75 percent of normal precipitation. The week saw a succession of cold fronts, which resulted in day-to-day swings in temperature from near normal to below normal. Showers accompanied the fronts of the 29th and 31st. Strong warming began on the 2nd ahead of a strong storm during the following week. The week's average temperature was 48.2 deg., which was 9.8 deg. Warmer than the previous week. Precipitation was 0.56 inch. Compared with the same week in 2007, the week was 10.8 deg. Warmer, and 0.05 inch drier.

The week February 3-9 saw temperatures about 7 degrees above normal, and rainfall about one-third normal. Severe weather struck East Texas on the afternoon of the 5th, with wind and hail damage in Bullard and Lindale. These storms were associated with a strong storm system and cold front, which brought a dramatic end to the very warm temperatures of early in the week. Weak fronts on the 6th, 7th, and 8th kept temperatures cool. Conditions were windy each day between the 3rd and 8th. The week's average temperature was 57.2 deg., and rainfall was 0.27 inch. This was 9.0 deg. Warmer than the previous week. Compared with the same week in 2007, the week was 8.8 deg. Warmer, and 0.20 inch wetter.

The week February 10-16 saw temperatures about 3 degrees above normal, and rainfall about 250 percent of normal. Two storm systems crossed during the week, one on the 12th and a second and stronger on the 16th. Both brought rain, with the second generating amounts of between two and six inches and a couple of occurrences of severe weather. The first storm was preceded by mild temperatures, followed by cooling, and warming again as the second storm approached. The week's average temperature was 54.9deg., and rainfall was 2.11 inches. This was 2.3 deg. Cooler than the previous week. Compared with the same week in 2007, the week was 14.3 deg. Warmer, and 1.73 inches wetter.

The week February 17-23 saw temperatures about 4 degrees cooler than normal, and rainfall about 175 percent of normal. Cold fronts crossed the region on the 17th, 20th, and 21st. As a result, temperatures showed considerable day-to-day variability. A temperature inversion on the 22nd held down high temperatures, and kept clouds and fog in the area for much of that day. Storm systems accompanying the fronts of the 17th and 21st brought the week's rains. The week's average temperature was 49.9 deg., and rainfall was 1.54 inches. The week was 5.0 deg. Cooler than the previous week. Compared with the same week in 2007, the week was 8.5 deg. Cooler, and 1.22 inches wetter.

The final six days of the month began and ended mild, with a sharp cooling trend in between. Windy weather between the 24th and 26th, and again on the 28th, required wind advisories. Measurable rain did not fall in the city, though there were showers on the evening of the 25th to the east and south of Tyler.
