24HR SNAP SHOT starting at NOON today
Water - .5 Snow - 4-6
Freezing levels - 2000' rising 3500' falling to 2500'
Winds 0 5-10 W
General Discussion: Heavy snow powered by two fronts will move through the Cascades today. The fronts slowed their approach last, so the timing has been pushed off a bit. Still expecting the moisture forecasted yesterday.
Long-term: The rest of the week will be mostly dry with a few light showers possible. There is another system developing in the Gulf of Alaska that may begin to affect us Sunday or early next week.
TRENDS AND TIMING
Precipitation: The snow intensity will increase this morning as the fronts make their way east. Our friend the PS Convergence Zone is expected to develop this afternoon. This will push orographics and intensify the precipitation. Snow will begin to taper off after midnight tonight. Light snow showers will persist through the early morning hours with tomorrow being mainly dry.
Freezing levels: Freezing levels will rise today to 3500’ and then fall back down to 2500’ overnight.
Winds: Westerly flow will follow the first front sometime after noon today. It will be possible to get some gusty periods as the fronts moves through, but no significant wind events are expected. jdm
