changing pattern... (am.02.apr.12)>

It certainly does not feel like an early April morning out there... unseasonably mild again just before sunrise.  I've recorded an overnight low of 64.9F (18.3C), and the humidity stands at 38%.

Our upper atmospheric pattern is in a state of transition effective immediately... which will lead to increasing instability this week.  There's plenty of sunshine early this morning, but we should see some clouds develop as the day wears on, leading to some scattered showers and thundershowers, mainly over the mountains, this afternoon and evening.  That routine should repeat itself tomorrow as well.  This is due to the fact that warm air at the surface is expected to remain in place, while cooler air gradually filters in aloft.  As I mentioned last night, this is not an organized "storm system"... but the atmosphere will be disturbed just enough this week to keep the chance of random showers and/or thundershowers in the forecast.  Be on guard if you have plans to be out and about, away from shelter.

Right through Friday, there is no real evidence that this unseasonably mild air mass is going to retreat... so expect temperatures to remain well above normal for early April!
