The activity starts today as a vigorous system moves through north-central California into the Intermountain West with rain, perhaps a few thunderstorms and heavy mountain snow. This system will move into the Upper Midwest tomorrow with a swath of heavy snow. Read More >

May 2019 Precipitation Highlights:

  • Numerous weather systems affected central and southeast Illinois during much of May 2019.  This resulted in above normal precipitation for most of the area, with the highest surpluses of 4-8" over the IL river valley.  Galesburg measured 13 inches of rainfall during May, which was 8.5 inches above normal. This was Galesburg's 3rd wettest month since records began in 1895.  Peoria had 8.26 inches of rain making it their 6th wettest May on record.  This heavy rainfall continued many rivers in flood through the spring, with moderate to major flooding continuing along much of the Mississippi and IL rivers.  A small portion of east central IL around Edgar county with Paris being three quarter inches below normal precipitation for the month.  Severe weather that was well below normal during the first half of May, became very active during the 2nd half of the month, especially during the last 10 days of the month.  This started with a widespread severe weather event on Wednesday night May 22-23rd with 65 severe weather reports over central IL including 4 tornadoes. There were 19 confirmed tornadoes in central IL during the week from May 22-29th.  Baseball size hail fell in Westville in Vermilion county during Thursday afternoon May 16 while tennis ball hail fell in De Land in Piatt county Tuesday afternoon May 28th.
