Get ready for the Jekyll and Hyde month of March to continue. Later this week you'll need to break out the shorts before you scramble again for the winter coat and scarf.

On Tuesday, we'll see some clouds to sun -- along with a continued chill in the air -- as temperatures will remain stuck in the unseasonably cold 40s. (Normal high is around 55 degrees).

On Wednesday, we will see a transitional day as milder air riding up over the chilly Canadian air will produce a few scattered afternoon showers as temperatures nudge into the 50s.

By Thursday, a strong storm system will be riding up to the west of us and this will allow for strong southerly winds to send temperatures soaring at least into the mid-60s and in a few places the mercury could make a run at 70 degrees. Unfortunately rain and possible scattered thunderstorms (when was the last time you heard thunderstorms in the forecast??) will make Thursday a dreary day with the threat of locally heavy rain, but at least it will be very mild.

In the wake of the storm, on Friday a late season arctic front will push through sending temperatures tumbling by day, back into the 40s, after a relatively mild Friday morning.

The temperature tumble will continue Friday night back down into the 20s. A reinforcing shot of arctic air will invade Saturday as we have a pretty good chance of some flurries or snow showers. I believe temperatures will never make it out of the 30s on Saturday and by Sunday morning, some record cold temperatures could fall. Readings by early Sunday morning should bottom out between 20 and 25 degrees in Philly and down into the teens in some of our northern and western suburbs.

I see no real prolonged spring warm-up as we start to move into April. I know you're jonesing to put this winter behind us, but I still see the possibility of some snow up until April 15th.  After that,  you'll be safe putting snow shovels away.
