GFS MAGA

To soon?  Anyway, GFS looks like it had it right all along.  Storm splits on the high pressure and mostly drives well north.  No rain for us Sunday, or any of California, really.  Still expecting a stellar day tomorrow, with highs pushing in the upper 60s, maybe even 70F.  Today, Thursday, should reach the mid 60s downtown.  On the westside it dipped below 40F for over three hours just before sunrise.  It is in the mid 50s now and temps have been on a steady increase since 8:20 this morning.  I see no reason why we should not warm another 10 degrees by early afternoon.  It was warm yesterday, flirting above and below the 7o degree mark for over two hours, with a peak of 72.8F.  Not shabby for early winter, on some of the shortest days of the year.

Early December evening.  


Friday seems like the peak of the warmth.  Sunshine and mild temps continue.  We will cool a bit over the weekend and into the New Year.  Low 60s expected.  Still gorgeous.  The noon run today of the GFS brings storms back to us as early as Tuesday night (January 2nd).  And a solid one as well.  That would last several days and bring up to an inch of rain by next Sunday.  Each run shifts the solution, so hopefully over the next 48 hours these begin to align.  What is promising is that each run shows a storm hitting us, just with different timing and intensity.  As these pattern shifts tend to be sluggish when moving from dry to wet, I'd wait a few more day before planning for a wet day outing.  You saw how that last storm appeared and disappeared in the forecast for New Years.  That said, in the time it took to write this post (I got distracted mid way through), we are back to a slight chance for a very little amount of rain Sunday night.  So, yeah, forecasts.

...and got distracted again.  Midnight hour run has the storm arriving Tuesday evening, then kind of retrograding through the start of Wednesday, before coming in strong Wednesday night into Thursday.  Maybe a break Friday, with more Friday night and into the weekend.  Wet beyond.  Looks like a full pattern change.  Get ready for some serious water.  Possibly.
