Attention User:

Update (1/22/2021): The maintenance has run significantly long and Nomads is still down past the expected time of restoration. We're re-running our late models now and hope to be caught up relatively soon.

(1/20/2021): NCEP will be performing maintenance which will result in a Nomads outage (our primary model data feed). This is scheduled for 1/21 12Z - 1/22 07Z. We have switched to backup feeds for most of our model data, however the GEFS will not update on our site during this outage; all other models are expected to continue to function normally. We apologize for any inconvenience this may cause.
