...A Very Warm Start to 2017...

What a difference a year makes!  One year ago the month of January
2016 ended up with near normal temperatures across Southeast
Texas.  Now, one year later, January 2017 ended up as one of the
top-ten warmest Januarys on record for the major climate sites.
When it comes to rainfall, rain fell mainly away from the coast
which helped to ease developing drought conditions over the inland
areas--many locations along the highway 59 corridor experienced
monthly totals between 5 and 10 inches.  However, the lack of 
coastal rainfall led to some locations to finish out the month 
with abnormally dry conditions.

Even with an overall warm month, there were a couple of colder
than normal periods.  The most remarkable followed a strong cold
front in which many inland counties experienced a hard freeze
around the 7th.  Warm conditions quickly returned by the middle of
the second week to the extent that most climate sites ended
January between 5 and 9 degrees above normal.  The following table
lists the ranking of monthly average temperatures for the first-
and second-order climate sites.

Here is the same listing for the temperature-reporting COOP sites
across the area.  Note that January 2017 was not in the top-ten
for the long-lived rural sites such as Danevang, Madisonville, and
Thompsons; although, other long-lived rural sites did record top-
ten warmth.

The U.S. Drought Monitor noted abnormally dry conditions over
areas that were northeast of the city of Houston just after the
New Year holiday.  Before the rainy period during mid-January, the
abnormally dry conditions had spread into portions of Madison and
Houston counties.  The rainfall eased these dry conditions but the
lack of overall rain at the coast led to abnormally dry conditions
being noted over most of Brazoria and Matagorda counties by
January 24th.

There were 19 daily records set at the first-order climate sites.
The following is a listing of the records tied or set in September
at College Station (CLL), Galveston (GLS), Hobby Airport (HOU), and 
the City of Houston (IAH).

- Airport (Arpt) site:  Easterwood Field (August 1931 to present)


The 7th was the coldest day of January across the area with every
climate site recording the coolest minimum and average temperature
on that date.  (Note that Conroe had two days with 18 degrees, the
7th and the 8th.)  The only other close dates with an extreme were
the 18th and 19th--the dates when most sites recorded maximum daily
rainfall. 

Here are the details of the daily extreme temperature and rainfall
data for November:

- Warmest daily maximum temperature...83 at LVJ on the 21st
- Coldest daily minimum temperature...17 at CLL and UTS on the 7th
- Warmest daily average temperature...75 at:
