Update at 6 PM. Really got toasty today....upper 60s to 70 on Puget Sound eastside and the southern Sound. But clouds are now rolling in now . I went cross country skiing at Blewett Pass today on the eastern slopes of the Cascades. At 4000-4800 ft there was snow, but it wasn't pleasant in many spots. Icy in the shade, rutted and full of holes everywhere. Spring skiing (which is ok) in the sun. Driving across Snoqualmie Pass, conditions looked pretty marginal. On the other hand, my vegetable garden is doing well and my pea seeds germinated in the warming soil.
Today will be very warm west of the Cascades. With offshore flow this morning and southerly flow this afternoon, temperatures will rise to the mid-60s in many locations, and at some upper 60s, approaching or reaching daily records. Probcast, the statistical package that works with ensemble forecasts (www.probcast.com), is very good at high temperatures under full sun...and here is the prediction for max temps today:
Note the cooler temps on the upslope (eastern) side of the Cascades. Another thing that is helpful is that the sun is much stronger now (equivalent to the middle-end of September!). And only some scattered high clouds to intercept the solar radiation.
Tomorrow things will go downhill...so today is the day..
