Fall 2014

2014FallDivisionalMap

The meteorological Fall from September to November has passed into memory lane again. Wow, time flies fast. It is already the start of the meteorological Winter, which is from December to February. It is also Christmas season, which seems to come faster every year before you even realize it. Ho! Ho! Ho! This Fall was a sharp contrast between warm and cold. Not only Fall was interesting weather wise, it was interesting from the medical aspect as Ebola (I got an Ebola blog, so check it out) came to America in Dallas and New York.

Temperature for Fall was within average despite a cold November. There are reasons why this Fall is not as cool as one would expect. First, October 2014 was very warm. How warm was October 2014 was for America?

November 2014 was quite cold. In fact it is in the top 10 coldest winter on record, 16th to be exact. Now, that is cold. November 2000 was colder than November 2014, which occurred in a weak La Nina. Interesting see that some of the coldest Novembers occur in El Nino like 1911, 1972, 1976, and 1991.

Let’s look at Texas. Fall was quite turbulent for Texas as Ebola virus paid a visit to Dallas. Three people came down with Ebola and one of them died.

Like America, even though November was cold, Fall 2014 was within the mean. The reason has to do with October. Here is the top 10 warmest October for Texas.

1.) 1947 71.80°F
2.) 1931 70.80°F
3.) 1934 70.70°F
4.) 1963 70.30°F
5.) 1950 69.80°F
6.) 2014 69.80°F
7.) 2004 69.70°F
8.) 1956/1962 69.40°F
9.) 1926 69.20°F
10.) 1941 69.10°F

October 2014 is the 6th warmest October on record for Texas. It is even warmer than October 2004, which was very warm for Southeast Texas. At least the Fall rainfall is above average as it is welcomed to put an end to the drought that has plagued Texas. Let’s look at November temperture for Texas.

19.) 1923/1937 52.40°F

November was cold for Texas as for most of the US east of the Rocky Mountains. Texas experienced its 13th coolest November on record as it ties with 1918. November 2000 was quite cold for Texas as it was very rainy and wet. Of course nothing compares to 1976, which was very cold. Many of these cold Novembers gave way to cold winters for Texas like in 1898, 1911, 1972, 1976, and 2000. Could this be a harbinger to come? Now, let’s look at Upper Texas Coast.

Upper Texas Coast 2014 Fall
Mean Temperature: 70.13°F
Total Rainfall: 12.52

Upper Texas Coast Fall Temperature (1895-2014)
Mean: 70.22°F
Median: 70.25°F
Standard Deviation: 1.58
Lowest: 64.27°F (1976)
Highest: 74.23°F (1931)

Upper Texas Coast Fall Rainfall (1895-2014)
Mean: 12.35
Median: 11.58
Standard Deviation: 4.90
Lowest: 3.12 (1924)
Highest: 27.47 (1998)

Again, despite a cold November, Fall 2014 had temperatures within the mean. There was a stark contrast between hot October and cold November. Here is the top 10 warmest October for Upper Texas Coast.

Top 10 Warmest October In Upper Texas Coast (1895-2014)
1.) 2004 76.80°F
2.) 1931/1941 75.40°F
3.) 1919/1947 75.10°F
4.) 1926/1962 74.20°F
5.) 1934 73.90°F
6.) 1963 73.80°F
7.) 1933 73.40°F
8.) 1956/1984/1998 73.30°F
9.) 1935 73.20°F
10.) 1928 73.10°F
11.) 2014 73.00°F
12.) 1950 72.90°F
13.) 1973 72.80°F
14.) 1954 72.70°F
15.) 1897/1938 72.60°F
16.) 1960/2007 72.50°F
17.) 1899/1927/1971/2006 72.40°F
18.) 1951/1991 72.30°F
19.) 1900 72.20°F
20.) 1946/2000/2013 72.10°F

It is the 11th warmest October on record. It is nowhere near the warmest October, which is 2004 and it was really warm. Interesting to note that following October 2004, it was a stormy and wet November and snow December with snow falling on Christmas Eve and Christmas. Many areas saw 1 to 3 inches with amounts as high as 13 inches! That is on level with the February 14-15, 1895. The Christmas Even 2004 snow event is easily 1 in 100,000 event for December or 1 in 1,000 event between December to March. White Christmas have never been recorded in Southeast Texas. I suspect White Christmas have happened on the Upper Texas Coast in the past, likely in the mid 19th century when there have been some big cold blasts. So, how did November compare to past November?

Top 20 Coolest November In Upper Texas Coast (1895-2014)
1.) 1976 52.80°F
2.) 1929/1972 55.20°F
3.) 1959 55.30°F
4.) 1932 55.40°F
5.) 1911 56.10°F
6.) 1898 56.30°F
7.) 1907 56.50°F
8.) 1895/1936 56.60°F
9.) 1979 56.90°F
10.) 1939/1980 57.00°F
11.) 1991 57.10°F
12.) 1993 57.20°F

17.) 1926 57.80°F
18.) 1951 58.10°F
19.) 1917 58.30°F
20.) 1912/1947/1997 58.40°F

It was a cold November for Upper Texas Coast as it is in top 20. It ranks 14th coldest November on record. There were cold Novembers back to back from 1991 to 1993. November 1976 is truly an outlier as it was very cold. In fact, there was freezing rain and sleet on November 28-29, 1976. Like most of America, Winter 1976-1977 was a very cold winter for Upper Texas Coast.

Interesting to note that the coldest Fall for America, Texas, and Upper Texas Coast is 1976. The Winter of 1976-1977 was very cold and one of the coldest on record. This past Fall does not come anywhere near 1976. Fall 1976 is truly rare. So, what could Winter 2014-2015 will be like? I will issue a forecast soon.
