March 2005 - Review of Weather Including  Temperatures and Precipitation for the Quad State Region.

Weather Summary for March 2005

A very active weather pattern persisted through March.  Numerous upper level and surface storm systems brought several episodes of rain.  In addition to Spring, March also brought the seasonís first severe weather.  Daily high temperatures ranged from the middle 30s into the middle 70s.  For the month, average temperatures ranged from 1 to 3 degrees below the normal (45 to 48 degrees).  Like February, rainfall was up to 1.75 inches below normal.

At the beginning of March, a large storm system was pulling off to the northeast.  Wraparound moisture produced trace amounts of rain and snow on the 1st.  In the upper levels, northwest flow continued through the first half of the month.  Two fast-moving storm systems passed across the region on the 7th-8th and 10th-11th.   Showers produced average amounts around one-quarter of an inch with higher amounts up to one-half inch.  Cold air aloft helped to produced sleet and small hail with many of the showers with heavier rain.

The second half of March was marked by numerous storm systems.  Between the 21st and 28th, a total of 3 strong storms passed over or near the region.  On the 21st, strong, closed, upper level and surface lows developed over the Southern Plains.  These lows moved northeast over the next couple of days bringing showers and thunderstorms.  Some of the stronger storms produced hail up to quarter (one inch) size.  A second storm system passed just to our south between the 24th and 26th  producing more showers and thunderstorms.  The last of the storm systems affected the region on Easter Sunday.  Showers and thunderstorms during the day brought locally heavy rainfall, large hail and high wind gusts of 60 to 70 mph.  Rainfall during each of the first two events averaged around one-half inch.  Easter rainfall measured between one and two inches with locally higher amounts close to three inches. 

The month ended with a quick cold front that passed across the region on the 30th.  Scattered showers and thunderstorms produced widespread hail reports and rain amounts between one-quarter and three-quarters of an inch.  The largest hail reported, golfball to baseball size, fell in Johnson County, Illinois.
