Another short synopsis.
Based on my analysis of the model runs this morning, there doesn’t appear to be too much change in the pattern over the next 5 – 7 days. Much of the country will remain cold temperatures, at freezing or below for minimum temperatures. Toward the weekend, these temperatures will begin to trend milder each day. Rain falling over the east today, should be turning to winter precipitation within the next 12 – 18 hours. If you click on the minimum temperature graphic, it will take you to the linked page, and you can choose the parameter you want, and see the changes over the course of the week.
Beginning around day 7, a very large low pressure area develops over Canada, just north the U.S. border. As this moves toward the east, by about day 9, another low is forecast to develop over the SW region of the U.S. near the four corners area, reinforcing the colder air brought down by the first low. This pretty much coincides with a turn to the negative of the Arctic Oscillation (AO).
The following is the forecast 96 hour accumulated snowfall from the GFS model.
Stay warm, and have a blessed day!
