Tuesday April 21 2020

A strong cold front will swing down and bring us a round of strong to severe storms. Then colder air will follow overnight, bringing another chance for a hard freeze inland.

Here is data many students need for their weather projects to document and journal conditions yesterday, climate report today, and daily weather map.
