This page will allow you to look at data up to 15 days into the past. The official resource for archived NWS data is the National Centers for Environmental Information (NCEI). NCEI provides online access to these data though the Archive Information Request System (AIRS), go to: https://www.ncdc.noaa.gov/has/HAS.DsSelect then click the Land-Based heading and then expand the Service Records Retention System (SRRS) Text Products to access the order form, documentation, and bulletin selection options.
When placing an order, you can enter the type of data and the period of time for the request. An email with details and links to access the data will be emailed to the provided address when processing is complete--usually less than 30 minutes after submission.
NCEI is our official source of archived data, however additional archived data can also be found through unofficial and non-operational sources such as IA state. Below are some additional links that may help:
