Warmer Weekend, But Chilly Pattern

April 25, 2008

SnapshotI just checked the winter snowfall total at Government Camp, near 4,000′ elevation on Mt. Hood. Looks like the after early next week (with more pass-elevation snow), we’ll have the snowiest winter up there since 1974-1975.  There were a string of years with 350-450" up there in the early-mid 1970s.  We sure won’t beat that since May is almost here!  But a heck of a winter at the lower-mid elevations in the Cascades.
A tough forecast the last 2 days for this weekend.  Luckily models seem to have formed a consensus on dry, but lots of high clouds tomorrow, then rain at some point Sunday afternoon.  Enjoy the warmer weather.  The Mark Magic Chart says a solidly sunny day tomorrow with the same atmospheric conditions would produce a high of 75-78.  That’s because there is a nice downslope easterly wind and 850mb temps rise to around +8 or so in the afternoon.  The WRF-GFS from the UofW keeps insisting on a high of 80 degrees tomorrow.  Wouldn’t that be nice if my forecast was that far off?

A cold trough returns later Monday through Thursday of next week, so enjoy the mild weather this weekend.  Mark Nelsen
