High
was 54F at the beginning (Thursday 06z), before temperatures rapidly dropped as
heavy rain arrived. Rain lightened in early afternoon before picking back up,
but it seems like the heaviest is staying just to the south, preventing the
extreme rainfall some of the high-resolution models showed, with 1.68” so far
as of 22 UTC. The rain and upward motion are not heavy enough for any
changeover to snow, with the low being 41F so far. Winds reached at least 24 kt
but probably will get stronger this evening. Rain will wind down tonight as the
storm pulls to the east, so we will lose the evaporational and dynamic cooling.
There will probably still be a lingering shower or two after 06z before completely
drying out. It will cool down slowly through the night, but widespread low
clouds and strong winds will prevent any quick radiational cooling and surface
inversion. The USL winds seem too high given the nighttime wind maximum, with
no sun to help mix stronger winds from aloft. Mostly cloudy skies and stiff
northerly winds will also prevent a quick warmup tomorrow, but a few breaks of
sun are likely when temperatures could spike a bit. The low will likely be at
the end (Saturday 06z) as skies clear out a little bit (still partly to mostly
cloudy) and winds calm down to borderline light enough for better radiational
cooling.
