We “weather guessers” call spring and fall “transition seasons”. During autumn in the northern hemisphere, nights are longer than days, temperature contrasts get wider between the southern and northern latitudes, and the polar front jetstream gets more active. Weather models struggle during the transition seasons.
There is nothing on radar in our area this morning.
*** Saturday afternoon through Monday night there will be more clouds, periods of scattered showers, and gusty afternoon winds. ***
*** A HARD FREEZE is possible Tuesday night. ***
Today… The ridge has shifted to our east, so we’ll see a few more clouds and slightly stronger afternoon winds.
Winds… Winds will be light and variable through most of the morning. Around noon winds will increase into the 10-20mph range out of the southwest and peak later in the afternoon around 25mph.
Temps… Highs will be in the low to high 70s and lows will be in the mid-30s to mid-40s.
Saturday through Monday… A double barrel low-pressure system will dip down into the Great Basin. Round 1 is Saturday afternoon to Sunday morning and round 2 is Monday afternoon to Tuesday morning. We’ll see more clouds, scattered showers, and gusty winds.
Precip total in the valley: 0.10” to 0.30” of rain. It will fall in spurts and be spotty.
Snow levels… Will start at 12,500ft Saturday afternoon and drop to 11,000ft by Monday morning and then to 9,500ft by Tuesday morning. I expect 2-4” of snow above 12,000ft, 1-2” 11,000-12,000ft. A dusting is possible down to 9,500ft Monday night.
Winds… Saturday afternoon gusts will be in the 25-30mph range. Sunday afternoon gusts will be in the 30-40mph range. Monday afternoon gusts will be in the 25-35mph range. Gusts in the mountains will be in the 45-55mph range. Sunday gusts to 60mph are possible along mountain ridges.
Temps… Saturday highs will be in the high 60s to mid-70s and lows will be in the high 30s to mid-40s. Sunday highs will be in the low to high 60s and lows will be in the low 30s to low 40s. Monday highs will be in the high 50s to mid-60s and lows will be in the high 20s to high 30s.
Tuesday… The trough will move through in the morning. There will be enough residual moisture and instability to kick up a few spotty showers and thunderstorms through the afternoon, mostly over the mountains. The snow level will be around 9,500ft, but I don’t expect much precip. Clouds will clear Tuesday night and give us our first chance for a hard freeze.
Winds… Afternoon winds will peak in the 15-20mph range.
Temps… Highs will be in the high 50s to mid-60s and lows will be in the mid-20s to mid-30s.
I’ll do another post tomorrow if my forecast is out of whack. Otherwise, I’ll probably do a post each day, Sunday, Monday, Tuesday, and Wednesday. Plus, I plan to do the September Summary/October Outlook on Sunday.
