Dry Forecast

May 10, 2006

Our dry May is set to continue into the 2nd half of the month.   Onshore flow should increase tonight ahead of a weakening cold front that moves overhead early tomorrow.  It may give us a sprinkle, but the big story will be quite a bit more cloud cover and cooler temps.

Just partly cloudy skies Friday, then it’s back to solid sunshine starting Saturday.

No change in the big picture from Saturday-Tuesday as a deep trough sets up well offshore and the first strong Western U.S. ridge of the warm season develops.  850 mb. temps on both the GFS & ECMWF are in the +16-+18 range for Monday afternoon.  That’s warm enough for 90 if the flow goes very light easterly for 1 day (like today!).  There is some "debate" about a passing shortwave giving us a marine push Tuesday, but even if that does occur, the big ridge holds at least through Wednesday or Thursday.  It’s going to feel like June or early July much of next week!
