The giant and powerful “Spring-Winter” storm system forming out West will be making headlines much of this week with a blizzard on the NW side and severe weather on its Southeast side, a textbook March storm as two low pressure areas merge (phase) and experience explosive development/deepening (known as bombogenesis).
Locally we get some gusty winds from it and some rain and thunderstorms to end the week but nothing crazy expected here so far.
Behind the system a jet stream change and a change of air mass from warmer than normal to cooler than normal.
Minimum temperatures will drop into the 30s by Sunday morning.
Temperatures will remain below normal for a stretch following the change before the next big warm-up, so the see-saw thermometer patterns goes on and on as expected. It probably will through April as well.
But cooler will also be drier.
In fact, we may even get a completely dry weekend coming up.
There’s even a chance it turns into an extended dry period. But then a more active storm pattern resumes by the last week of the month into the start of April and the April warm-ups will of course be noticeably stronger.

March is known for big storms. Nobody who lived through it will ever forget the 1993 blizzard with thunder and lightning which struck days after high temperatures in the 50s and 60s:
