Get Ready For Some Snow; JRWeather Winter Storm Warning In Effect

Local Update...
   JRWeather Winter Storm Warning In Effect From 12AM Wednesday Until 12AM Thursday...


JRWeather WINTER STORM WARNING
     JRWeather has issued a Winter Storm Warning for All Of Vermont and Northern New York From 12AM Wednesday Until 12AM Thursday.

     A low pressure system will move from the Mississippi Valley area, and track northeast, and across extreme Southern New England Wednesday afternoon, then up into the Canadian Maritimes by Thursday afternoon.

     Snow will overspread the region by Wednesday morning, and become heavy at times in the afternoon. Snowfall rates may reach 1 inch per hour for a time Wednesday. Snow will start to tapper off, and have pretty much come to an end by Midnight. Total snow accumulations in the Warning area look to range from 6-10 inches with locally higher amounts along the Western Slopes of the Green Mountains. More data is coming in, and snowfall totals may have to be increased even more later this evening.

     A Winter Storm Warning is issued when severe winter weather is likely. In this case the Winter Storm Warning is for heavy amounts of snow. Travel will become hazardous Wednesday. If you MUST travel, use extreme caution. Stay tuned for further updates.


DISCUSSION
     Things looking on track for a significant snowstorm on Wednesday. The overall storm is extremely impressive. Winter Storm Warnings extend from the United States/ Mexican border in Texas, all the way to the United States/ Canadian border in Maine. For our area it should be all or mainly snow. Extreme southern Vermont may see some sleet mix in for a brief time Wednesday afternoon.
     New model data coming in, is suggesting that I will likely need to increase my snow amounts. I will await the new run of the GFS model before I make any changes. The National Weather Service has increased snow totals to 8-14 inches now. That's up from 6-12 earlier this morning. They have also stepped up the Winter Weather Advisory to a Warning across the St. Lawrence Valley for 6-10 inches of snow. That's increased from the 4-6 inches forecasted this morning. Right now though I am holding with 6-10 inches for the entire region, with higher amounts along the western slopes. If the GFS shows what the NAM model has, then I will likely up amounts to the 8-14 inch range as well. Stay tuned!

I have updated the video. Unfortunately right after I had published it, new winter alerts were issued for the area. So some of what you see or hear may be slightly different from this post. The video is still processing from the upload to YouTube, so the video may be unavailable for up to 30 minutes or so.
