The National Weather Service websites have been and are continuing with major maintenance and upgrades over the past 24 hours. The sites are experiencing occasional ups and downs during this maintenance period.
It is possible that these intermittent outages will continue overnight. Please make sure when the site appears to be current that the products that you are viewing are in fact current products with up-to-date dates and times.
We are sorry if this is an inconvenience for you and hopefully this issue will be resolved by 8 AM CDT on Friday.
