Rain Coming

April 12, 2006

Nicer day than expected today…at least temperature-wise.  Shows us how easily April sunshine can push temperatures up.

One last dry day tomorrow as westerly flow increases overhead.  We’ll be feeling the edges of an approaching upper-level trough by Thursday evening.   I’m impressed by the cold air with this.  ETA 00z cross-sections show freezing levels down to around 2000′ Saturday and Sunday.  I don’t think snow will fall much lower than that, but that cold of an airmass along with April sunbreaks should give us vigorous showers both days, after Friday’s steady cold front rain.

We may also see a frost outside of Portland Sunday or Monday night as skies begin to clear out.

Enjoy one last dry day!
