This might be a good time to talk a bit about NWS weather terminology.
Many people operate under the impression that an ADVISORY ranks somewhere below a WATCH. Not so. Here is the actual ranking, from low to high:
Watch: Conditions are favorable for an event
Advisory: The event is expected
Warning: The event is happening
I thought this might be helpful, especially when assessing the threat of high impact weather events like severe thunderstorms or tornadoes.
Thus the NWS definition at the bottom of this advisory, letting everyone know the likelihood of this event happening.
...FROST ADVISORY IN EFFECT FROM 1 AM TO 9 AM CDT FRIDAY...
The National Weather Service in Springfield has issued a Frost
Advisory, which is in effect from 1 AM to 9 AM CDT Friday.
* TEMPERATURE...Temperatures will fall into the lower and middle
30s late tonight and early Friday morning. The colder locations
may fall to the freezing mark. These cold temperatures along
with a light will result in areas of frost.
* IMPACTS...Sensitive outdoor plants may be killed if left
A Frost Advisory means that frost is expected.
