Mostly clear skies with just some thin high
clouds will lead to good radiational cooling at first tonight, but a bit of
downsloping westerly winds could slow down the cool down later on. However, the
winds are only marginally strong enough to prevent ideal radiational cooling,
and brief but pronounced dips during any calmer periods are still expected, so
it will verify either close to the cooler models (like USL) or probably even
cooler than that. Westerly winds, sunshine, and a warm air mass aloft mixing
down to the surface somewhat will lead to a rapid warmup tomorrow, with winds
shifting to northwest and becoming much stronger in the evening behind the cold
front. A short-lived stronger burst of wind is likely right behind the front,
which the USL tends to not handle well and thus probably underestimates the
maximum wind. The cold front should arrive late enough to not affect the high,
though some afternoon mid-level clouds could lower the high by 1-2F or so.
There might be an isolated shower with the cold front, but measurable rain is
unlikely given the dry air mass and downsloping, though any virga could enhance
the burst of wind through evaporational cooling and the associated gust front.
