Forecast on track with a little cooler day today. Some of the cooler air that dropped out of Western Canada last night will spread into the Great Basin, building surface pressures and providing for a gentle NE/SW gradient. Any clouds that develop this afternoon are due to some marginal instability that will blow off from Nevada toward the sierra crest and may provide for a few isolated showers late in the day. Note; Any showers that may develop are not due to snow melt! High pressure will build back in Wednesday afternoon for some warming, with a trend of warming through Friday. (Friday’s Highs Low 70s)
A weak trof with some cooling is still expected Saturday and Sunday. Highs Sunday in Mammoth in the low 60s
The Upper low that brought unseasonable cool and wet weather to the high country moved east last night, far enough east to allow for plenty of drying and lots of sunshine. Monday’s high should reach the mid 60s with lows tonight in the drier air below freezing….
Tomorrow, a weak back door cold front will kick up a little NE wind over the upper elevations. Temperatures will remain about the same as today. A little warmer weather can be expected Wednesday with much more warming Thursday and Friday. High in the low 70s.
The weekend outlook shows the bottom of a Trof moving through the sierra with the wet portion in the Pacific NW and extreme Northern CA. Expect the weekend to cool to the mid 60s with some high clouds and westerly breezes.
As highlighted above, the longer range models shows another vigorous Trof for the 2nd half of next week… This may be similar to what we had, last week.
