Blizzard of 93

The 0z & 6z model runs continued the positive trend for some CTP snow on Tuesday. The LSV, especially those areas near I-81, now look to be in play for the chance at a couple of inches of snow by late Tuesday. Here is the 6z GFS.

@pasnownut & @MAG5035 What are your thoughts on the Saturday pm to Sunday am winter storm potential?

The 18z EPS looks good for the overnight Sunday potential.

The 18z Euro improved the chance of some snow for us overnight Saturday into Sunday am.

Happy New Year everyone! We have the chance at a couple of winter weather events this week. The first chance is Saturday night into Sunday morning. It will depend on if a secondary low develops, & if so, the location will determine if we can get a little snow out of it. Here is the 12z Canadian & Euro.

I thought that with the year ending, today would be a good time to post this chart that CTP has on their website that shows the Harrisburg snow totals since 1980. Looking back on the last 40 years is a good reminder that some of our memorable snow years were surrounded by bad snow seasons. The best example of that is the epic seasons of 93-94 & 95-96 had the terrible winter of 94-95 sandwiched in the middle. I can’t imagine the sad state of this place During the run of bad winters of 05-06 to 08-09 or the pitiful period snow between 96-97 to 01-02. This chart is a good reminder that for many years, snow lovers suffer while waiting for a good or great or even average winter season in our area. Harrisburg has been on a very good run recently, with 5 out of the last 6 years exceeding the 30.9 inch average seasonal snow total.

The middle of next week still has potential to provide us with a snow storm. The 0z models had the Euro showing a cutter, the Canadian was close with an inland runner, & the GFS said “what storm?”. There is still lots of time to determine our chances for PA Farm Show week.

I can’t wait until it snows next week so we have something to discuss other than weeds.

Yes, the 0z Euro, 0z Canadian & 6z GFS all like the idea of a winter storm around the 7th of January.

The old PA Farm Show snow rule could be in effect this year. This is the best looking GEFS run that I have seen in some time. Of course, take snow maps at long range with a grain of salt, but for the purpose of spotting trends, they help to tell the possible story. Most of the snow on this 6z GEFS map falls during the Farm Show week! It looks like the possibility of a few events. There are some nice hits among the individual ensemble members.

Yes, that was a nice track on the Euro. It looks like the period just after this storm that you mentioned will turn favorable for winter storm chances. The GEFS is quite cold & active with chances beginning just after next weekend through the following week. When is the PA farm show this year ? Maybe for once that will help to bring us some snow ?!

There should be a colder period developing next weekend. The question will then be if it will lock in or move out after the following week. The MJO & EPO will have a lot to say about how the pattern will evolve. If the MJO can take a longer loop through phase 7 & 8 as some models indicated yesterday, then that could help the pattern turn more favorable for winter weather in the east. The EPS yesterday showed the EPO heading toward & staying near neutral territory over the next couple of weeks. The SOI also has been very negative against it’s base state for the last 4 days with values near -20. Hopefully we will be back to Winter storm tracking as we head into the the New Year.

Merry Christmas everyone ! The 0z GFS had a gift for us which would get delivered on January 5th in the form of a coastal storm.

The 12z GFS agrees with you.

Thanks MAG ! I think that we will be actively tracking a winter storm threat between New Year’s & the end of the first week of the new year.
