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

Weather Summary for April 2005

April started off very spring-like with occasional showers and thunderstorms and temperatures warming into the 70s and even a few 80s.  The last week of the month, however, was cloudy and showery with temperatures struggling into the 50s and 60s.

For the month, average temperatures ranged from 1 to 2 degrees above normal (56 to 59 degrees).  Rainfall was highly variable ranging from 1 inch above normal to 2.50 inches below normal.

An area of low pressure passed just to the south of the quad state region during the first few days of April.  Showers on the north side of the system produced light rain with most areas receiving less than one-quarter of an inch.  High pressure briefly built across the region sending high temperatures into the upper 70s.  Another storm system developed in the Southern Plains and headed east on the 5th.  Showers and a few thunderstorms developed ahead of a weakening frontal boundary.  Rainfall amounts between the 6th and 7th varied greatly depending on the locations of storms.  Some areas received up to one inch of rain.  High pressure again dominated for a couple of days sending highs to around 80 degrees.

A warm front moved north across the region on the 10th as an upper level low developed over the Southern Plains.  This upper level low moved northeast producing numerous showers and thunderstorms on the 12th.  Hail and cold air funnels were reported during the day.  Storms over Cape Girardeau County in southeast Missouri continued to generate in the same location and only move very slowly.  Two to three inches of rainfall in a span of just a couple of hours produced flash flooding between Jackson and Fruitland.  Dry weather dominated the forecast between the 13th and 19th.  Daily highs topped out around 80 degrees. 

The weather during the last week of April would offer quite a change with an upper level low meandering around the Great Lakes.  Northwest flow dominated the upper levels as several storm systems rotated around the low.  Showers and thunderstorms occurred almost daily between the 19th and 30th.  Some of these storms were severe, producing large hail, damaging wind gusts and very heavy, though brief, rainfall.  Total rainfall amounts during this time ranged from 1 to 3 inches.
