Weather Synopsis for Thursday & Friday
It's a bit of rinse and repeat for the weather today, though with a lower chance of thunderstorms in the afternoon. Perhaps more importantly, with less instability in the atmosphere, any thunderstorms that do develop should be much less severe than Wednesday evening's storms.The stacked low offshore has drifted a bit closer and it's spinning some more light and scattered showers into the the mountains during the day today. There's a chance for some occasional sun breaks before cloud cover rebounds in the afternoon. If the sun comes out for longer and heats things up a bit more, that should drive a bit more convective activity (locally stronger showers and chances for t-storms) this afternoon. Things have cooled substantially from the summer-like temperatures we have been experiencing, with snow levels falling into the 4500-5000ft range and holding steady through the day. Showery activity picks up for all zones on both sides of the crest this evening, with the passes a bit less favored. A short-wave on Friday focuses things a bit more as the upper-low transitions to a trough with continued showers and cooling. Snow levels drop overnight into the 4000-4500ft range and hang there on Friday. Things look to dryout some on Saturday in advance of the next system arriving late weekend.
