Lingering late winter and early spring cold fronts kept
March 2003 cooler than normal over the eastern parts
of South Central Texas; however, over western parts
of the area, the shallow cool air modified rapidly,
as more sunshine in the day warmed afternoons enough
to increase the average March temperature to near
and above normal.
After a wet February, March 2003 ended up drier than normal
over South Central Texas.
The cloudy conditions that ended February carried over
to the first 2 days of March 2003. On Monday the 3rd,
an area of showers and thunderstorms swept across the
region in the early to late morning hours, replaced by
partly cloudy skies in the afternoon.
By March 6th to the
13th a warming trend followed. On March 13th,
afternoon highs warmed up to around 80 to the 80s
ahead of a fast moving cold front. Thunderstorms
formed on the cold front in the late afternoon over
parts of Kinney and Val Verde County. One thunderstorm
caused golfball size hail near Brackettville.
Slightly cooler conditions followed the 14th.
On the weekend of the 15th and 16th, clouds began to
increase, ahead of a rapidly moving weather system.
This weather system came through the area in the
morning hours of Tuesday, March 18th, bringing an
area of showers and thunderstorms from parts
of Val Verde and Edwards County to parts of Bandera, Kerr, Gillespie, Llano and Burnet
Counties around 2 to 3 AM. Some of the
thunderstorms produced 0.75 inch hail in Llano
County in the pre dawn hours. The showers and
thunderstorms moved east affecting the Ausitn
and San Antonio areas around and after
sunrise. Skies cleared up in the afternoon
of the Tuesday the 18th. Another surge of
dry air, with a weather system aloft, swept
across Central and South Central Texas
Wednesday, March 19th, bringing strong west
winds, that gusted to near 30 to 45 mph.
Spring began on Thursday, March 20th at 700 PM CST.
Although warmer weather comes in March and April, there
have been periods of cold or cool outbreaks in March and
April during the past.
See History of Late March and April Cold Outbreaks.
Even as spring begins, there have been extremes that
showed up over the region in the past.

The first spring rain making weather system
for 2003 affected
the area Saturday the 22nd, with showers
and thunderstorms. Mostly clear skies
followed Sunday the 23rd, as afternoon highs
rose the lower 80s over western parts
of South Central Texas to 70s across the
eastern part of the area.
The week of Monday the 24th to Friday the 28th,
brought a severe weather event that broke out
in the mid to late afternoon, Tuesday the 25th.
Showers and thunderstorms formed on a cold front,
and moved south and southeast. Some of the
thunderstorms became severe and an F0 Tornado
occurred 2 miles south of Comfort. Large hail accompanied some of the thunderstorms, and
some of the severe reports are referenced by
The Preliminary Local Storm Report For
March 25th.
Strong damaging winds accompanied the
thunderstorms near Comfort and also
the thunderstorms over parts of Dimmit and
Zavala Counties.
Skies cleared in the night and pre dawn hours
of the 25th/26th, with sunny conditions and
calm weather during the day of Wednesday the 26th.
The month from the 27th to 30th witnessed more
extremes in temperature. Nearly summer like conditions on Thursday the 27th were replaced
by cooler days the 28th to the 30th. Afternoon
highs the 27th made it to the 90s over west parts
of South Central
Texas to 80s over eastern parts of the area.
A strong late March cold front followed the
night of the 27th and early morning of the 28th,
bringing windy and cooler conditions.
Compared to the 27th, daytime highs were 20 to 30
degrees cooler
on Friday the 28th.
The cold air kept filtering over the area on
Saturday the 29th. Under mostly clear
skies, temperatures fell to at and below freezing
in the early morning of Sunday, March 30th.
Record lows for March 30th of 31 was observed
at Del Rio and Austin Bergstrom International
Airport. The lows of 37 at Austin Mabry
and 30 at San Antonio International Airport
were not record lows for March 30th.
Under clear skies afternoon highs on Sunday March 30th warmed up to the upper 60s to near 70.
Unlike the cloudy skies in the beginning of
March, March 2003 ended with clear and
pleasant weather. Under clear skies with abundant sunshine, afternoon highs on
the 31st rose to into the 70s, with near
80 in the Del Rio area.
The latest 30 day outlook for April 2003 from
the National
Center of Environmental Prediction calls for the Average Temperature
to be below normal for most of
South Central Texas, except near normal over
the extreme western sections near Del Rio.
The 30 day outlook calls for Precipitation to be near
Normal over Central and
South Central Texas.
The latest 3 Month or 90
Day Outlook for March 2003 to May 2003 calls for
below Normal Temperatures and Above Normal Precipitation
over Central and South
Central Texas. These latest 30 day and 90 day Outlooks were issued
on Wednesday, March 19, 2002, from the National Center of Environmental
Prediction. To see the latest 30 and 90 day Monthly/Seasonal Outlooks
Go
to the Latest 30 and 90 Day Monthly/Seasonal Forecast from the
National Center of Environmental Prediction.
Note: These 30 day outlooks are based primarily on climate phenomena
that exhibit a relatively large degree of predictability such
as the El Nino/Southern Oscillation (ENSO) cycle, as well as decade-to-decade
variability and trends. Extra tropical circulation patterns on
monthly to seasonal time scales [such as the North Atlantic Oscillation
(NAO)] also significantly impact the monthly and seasonal temperature
and precipitation patterns, sometimes distorting expected ENSO-related
patterns. However, since the long-range predictability of these
extra tropical circulation patterns is very limited, they are
not explicitly represented in the extended-range forecasts. To
take these uncertainties into account, probabilities of temperature
and precipitation are decreased (increased) in regions where the
variability associated with these patterns is large (small).
