Minor reality check now, 60s return by Friday

Our weather roller coaster ride continues.

Our minor March reality check lasts about 24 hours this time.

Tomorrow afternoon the sun pushes temps back into the 50s. By Friday, that spring in your step could be payday, and a warm sun with temps in the 60s once again. Cool high pressure slides east and milder southwest breezes return by Friday. The maps:

Here's the big picture over the next week. Temps push 25 degrees above average again by Friday. A cool rain moves in by Sunday. Then temps spike one more time before what looks like a more significant cool front late next week. It is still March, after all.

False spring?

It looks like we'll see a couple more stabs of cold in the last half of March. The magnitude of the cold snaps are still in question, but the upper air pattern favors another frigid shot or two around St. Patty's Day.

NOAA's 16-day guidance is cranking out some temperatures in the teens and single digits in late March. I'm not convinced we'll get this cold, but the trend is certainly there for colder weather in the second half of March. This particular product has a tendency to overdo cold in week 2, let's see if this modifies with time.

Meanwhile out west...
