Only if we stay in the liquor headline. Of course this counts during grilling season in the spring and summer

40-50 are in gusts Pete. I believe sustained winds for a time will be in that 15 to 30 mph range for later Thurs night, all of Fri and into Fri night as well. Gusting will lower to 30 on Christmas Eve and further on Christmas Day. There will be travel impacts to some degree all weekend long. The worst being Thurs night and Friday and even into Fri night as well with widespread impacts. Could be tricky in spots Sat and isolated spots Sun is my thinking.

The definition is winds over 35 mph ,snowing of course and visibility less that a 1/4 mile for at least 3 hours. We get close during this time period but will probably come up short in one area or so.

Didn't the old criteria involve temperature also? Either a certain temperature had to be obtained or a certain temperature drop had to occur? This could even meet the old criteria considering the temperature and temperature drop we are going to see.

Just found out I have to go to the in-laws in Peru Indiana tomorrow for Christmas weekend. I wasn't expecting to have to make this trip. Family health issues have made this a necessity, so I can report ground observations from Peru as this thing unfolds in northern Indiana.

And you know what is going to be the sad thing about that, Tim. So many local media hacks are going to be using the word blizzard even though they have no clue what the definition of a blizzard is. I can see it coming right now on that.

Wow! Please be careful, Doug! So sorry that this happened Bro. Safe travels my friend. Here is the official NWS definition:

Blizzard
(abbrev. BLZD)- A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer:
Sustained wind or frequent gusts to 35 miles an hour or greater; and
Considerable falling and/or blowing snow (i.e., reducing visibility frequently to less than ¼ mile)
