3/16- STORM WATCH- Vast Disagreement

Good Thursday all-

We have model disagreement in the extreme for a storm coming just two days from now, which is a change from yesterday. In a bizarre twist, the GFS model has developed Saturday's system off the coast and just near enough to deliver a moderate to major snowfall on Saturday afternoon and Sunday on the order of a statewide 4 to 8 inches or so, while the Euro has decided to go with about 2-4" south of I-84 and 1-2" north of there. The most likely result is probably somewhere in between...so for now I will go with 3-6" of snow with locally higher amounts possible in the southern third or so of the state. That said, I would absolutely love model agreement so...the high end of a 5-10" snowfall statewide...and the low end of a 1-2" type situation for everyone...both remain on the table as about one-in-four chances. Hmm...we'll just have to wait and see.

Thankfully, we have no weather worries until then (unless you hate cold weather) with highs in the 30s, lows in the low 20s, and mostly sunny skies both today and tomorrow. The early part of next week looks dry, but we should watch Tuesday for the risk of some mixed precipitation.

The next name on the winter storm list is Frank. It is noteworthy that we have only used the "F" name one time in the last 21 years...so it would be quite an unusual event!

Today in weather history- March 16, 1975- The biggest single snowstorm in Oregon state history drops 119" on Crater Lake.

Additionally, March 16, 1986- A rare tornado very nearly hits Disneyland, CA...but manages to blow off roofs as near as one and a half miles away. Nearly a disaster, but fortunately averted.
