Another coastal storm – There is yet another coastal storm in the works for the first half of this week as the Mid-Atlantic tries to get it’s first good snowfall of the season, and southern New England could be looking at a foot or more.
Great Lakes/Northeast snow late – Another snow-laden system will work into the Great Lakes and Northeast from western Canada at the end of this week, which could produce widespread snowfall on the order of 2-4″ with locally higher amounts.
The Southwest remains dry – An upper-level ridge continues to dominate the weather in the West as below normal precipitation continues in the Southwest.
While my map will need some improvements (especially to add higher snowfall totals to the Apps), my general thoughts remain the same with the “stripe” of higher snowfall totals, which will likely be adjusted a bit for orientation purposes. A final call will come out tomorrow afternoon. This storm is expected to continue to track northeast just offshore, which will bring some significant snow to the New England coast as guidance consistently hints at totals approaching 1-2 feet in southern New England as the storm moves by Wednesday into Thursday. Most of the snow should come from the back edge (NW/W part) of the system as it moves through and gives some areas a dose of rain and warmer temperatures before it changes over to snow late.
At the end of the work week, a low pressure system diving in from western Canada could bring widespread snowfall to the Great Lakes and Northeast, which is currently forecast to drop a widespread area of 2-4 inches of snow in these areas. Locally higher amounts of 4-8+ inches will be possible, especially in areas with lake-enhanced snowfall. The actual track of the storm has plenty of time to move a little further north or south, and could prove to be a near-miss for many areas or it could surprise some folks in the northern Mid-Atlantic states with some snow (or rain).
A ridge of high pressure in the East Pacific continues to drive a warm, dry pattern over the Southwest, and the pattern shows little signs of changing this in the upcoming weeks. If this pattern continues, the Southwest could start to see drought issues not too long from now. This is in stark contrast to the heavy precipitation the Southwest was seeing a month ago.
Phew! It has been a long day. More on the coastal storm tomorrow!
