12/18/2009 Weather
Short term: A weak system will bring a chance of some light snow tonight. The next system will drive up from the south tomorrow night bringing a mix snow and rain event to the Cascades tomorrow night. If we get lucky with the temps, this could be a good snow producer for us.
Long-term: Next week is very uncertain due to the inconsistency of the models. In general is it looking cooler with some weak systems being spun in mid week or so. No huge weather events expected at this time. Sorry, that’s all I got for now.
