The summer heat will be surging into the plains this week but the chilly spring air won't be far away. We will be right in between the two where the storm track will be active. While the severe weather chances this week will be low, several rounds of rain could provide 2-3" in the next 7 days. The first chance of heavy rain arrives overnight Sunday into Monday morning. While Tuesday will be dry, more heavy rain is expected Wednesday into Thursday. A third wave of rain could make it into the area by next weekend.
