Although
there was almost no wind last night, the thicker high clouds only allowed for a
cooldown to 41F. The clouds also led to a high of only 60F, actually lower than
some model guidance. The max wind was only 7 or 8 kt, which is to be expected
given the almost complete absence of pressure gradient. The coastal storm will
be going farther offshore than earlier expected, leading to clearing skies
tonight and good radiational cooling given the continued lack of wind. One
caveat is some possible scattered low clouds (around 850 hPa) with a thin layer
of near-saturation that could slow the cooldown a bit. Assuming that will only
have a minimal impact as I expect, it will likely get as cool or cooler than
last night, but then it will get much warmer tomorrow than today with nearly
full sunshine and a slightly warmer air mass. Winds will also be very light
like today, with no pressure gradient. With the clearer skies, model bias should be more similar to day 5 than to day 6 (i.e. warmer for high and cooler for low).
