Ah! Mild weather is coming and just in time, too. The spring season officially starts this Saturday. By then, temperatures will be in the 60s all across the mid-Atlantic and Ohio Valley regions, and not too far to the south, 70 degrees will be reached.

The trend toward mild weather in the East has already begun, but things will really get going Thursday and Friday. Appropriately, spring fever warnings are now in effect for much of the East.

With deepest regrets, I must point out that this warmup is just a tease. Colder weather will return to the Midwest this weekend, then reach the Northeast early next week. The transition between air masses will probably be accompanied by a short period of heavy rain.
