Computer models for the past 10 days waffled all over the place with the possibility of a coastal weekend storm in the Philadelphia region.

Whenever I see such inconsistency as well as both the North Atlantic and Arctic oscillations in positive phases — lowering chances of snow — it points away from chances of a significant storm.

The entire Delaware Valley will not be dealing with a storm this weekend, and as a matter of fact, this should be a good weekend to take advantage of some last-minute shopping. Temperatures will be in the 40s with a decent amount of sunshine.

On Monday, we should see some rain, not snow.

As for your Christmas Eve and Christmas Day:

Intense energy diving down from the Northern Plains as a deep trough will create a monster of a storm in the Mississippi Valley by 8 p.m. Tuesday. It will rapidly intensify over West Virginia early in the morning of Dec. 24.

It's destined to become a super-intense storm centered over the Great Lakes by 8 p.m. that evening.

This should produce near or blizzard conditions across Central Great Lakes and, perhaps, extend south across sections of the Ohio Valley into the morning hours of Christmas.

For Philly and the entire Delaware Valley on Christmas Eve, we will be in the warm sector as howling southeast winds, gusts possibly exceeding 50 miles per hour, especially along the Jersey Shore, should lead to significant tidal flooding and beach erosion. Everywhere else will see plenty of street flooding and heavy rains — but mild temperatures climbing into the 50s.

Then on Christmas, it will remain very windy but dry with just the chance of a flurry as temperatures dip a bit into the 38-to-43 range. In other words, there will be no white Christmas.
