Bland weather continues–it is nice out there, though…

Rather mild and dry springtime weather prevails across CA. This has been supported by a West Coast ridge of high pressure at the surface and punctuated by a lack of precipitation over the western United States. The prevailing pattern is expect to change little over the next 7-10 days, and so most can expect warm weather and sunny skies to be the norm through the first days in April. The ECMWF and now, to a lesser extent, the GFS, has been indicating the potential for a cold inside-slider type system out on days 6/7. The GFS has been mostly dry, but the ECMWF would indicate the potential for some convective precipitation. In any event, this is not going to be a significant precip event, and there are none on the horizon. Although NorCal did receive substantial and very beneficial precip in February, it has been so dry before and since that period that we may again be looking at some renewed water supply issues. It does not appear that the supply situation will be quite as dire as it looked like it might have been earlier this rain season, but we will still be facing major defecits and will be left vulnerable to additional dry years in the future.
