We are watching Colorado early this week for a rare May snow event which will intensify Tuesday night. The I-25 corridor could see anywhere between 2 to 6 inches of heavy impactful snow. An advancing cold front will bring cooler temperatures to much of the Eastern CONUS including a Plains freeze event Wednesday & Thursday. The long range pattern is tilting dry and warm for much of the Plains. The Southeast & Mid-Atlantic are likely to see wetter conditions from this pattern however
