Springtime is a period of transition from the cold
and relatively dry months of winter toward the hot and
more humid climate of summer. Spring in Eastern Oklahoma
and Northwest Arkansas is no different, often times
bringing a wide variety of weather elements to the area
ranging from freezing temperatures and occasional snow to
unusually hot temperatures with showers and thunderstorms
bringing heavy rainfall and occasional gusty winds, hail,
and tornadoes.
The following tables
summarize the kind of weather usually seen during the
spring months and the weather extremes the area has
experienced in years gone by. Also, don't forget that...
Spring officially begins on Tuesday,
March 20th, 2007 at 7:07 PM CDT
and that...
Daylight Savings Time begins on
Sunday, March 11th, 2007 at 2 AM
*New law goes into effect starting this year.
