0900 Tuesday 11/11/04
The Snapshot: Darn this pesky moist inversion layer sneaking
in from the east; no significant snow is expected out of this. Mostly dry and
cold conditions will continue through Thursday. There is a chance of some light snow on Thursday/Friday.
The Science: Strong easterly flow will
continue to push cold and relatively dry air into the PNW for most of the week. Warmer air west of the crest has created
conditions for these thick inversion clouds.
High pressure aloft will fight to break up the clouds later today and
tonight. A storm tracking into Oregon on Thursday could
push some snow showers as far north as Stevens Pass. The
weekend is trending dry as high-pressure rebuilds over the region.
4-7day
Long Range: Long range models are now changing
every run; so confidence is dropping. Temperatures will begin to warm towards the
end of the weekend with the next chance of any significant moisture sometime
next week.
