.UPDATE...

.SHORT TERM...
(Issued 215 PM CDT Wed Apr 5 2023)

Tonight through Thursday night:

Cold front well to the east and the gusty west wind/caa regime has
settled in. Wraparound stratocu will persist for a time into this
evening with some potential for scattering out as the night wears
on. Winds proggd to remain gusty into Thursday with a lingering
pressure gradient. The surface high settles across Thursday night.
Some 850mb return waa is proggd in some solutions to generate light
precip across parts of central WI. At this point will leave our northern
reaches dry per the NBM pops.

&&

.LONG TERM...
(Issued 215 PM CDT Wed Apr 5 2023)

Friday through Saturday:

The high works east this period though low level flow remains
overall anticyclonic. The waa regime strengthens further with a
renewed band of frontogenetical forcing proggd to kick off a band
of precip. This one looks a little more vigorous though some
indications it will either graze our northern counties or miss us
entirely. For now will stick with the NBM pops and keep a chance
across our north this period. Could be a mix for a time and then
transition to mainly rain for Saturday.

Sunday:

Shaping up to be a warm and pleasant day. Low pressure well to our
northwest and high pressure to the southeast means south or
southwest winds with decent 925/850 warming.

Sunday night through Monday night:

A weak trough may set off a few showers but by and large no
appreciable airmass change so the warming trend continues.

Tuesday through Wednesday:

Broad anticyclonic mid level ridging builds across with a pronounced
warmup continuing. 70s look quite likely.

.AVIATION...
(Issued 901 PM CDT Wed Apr 5 2023)

VFR conditions are expected overnight and tomorrow, with
continued gusty west winds. Winds will slowly ease during the
afternoon hours.

.MARINE...
(Issued 215 PM CDT Wed Apr 5 2023)

Gale Warning remains in effect this period with tight pressure
gradient in the wake of a cold front. West winds will persist into
Thursday. Gradient will ease soonest in the south so have the
southern warning expiring at 7 AM with the northern warning
continuing throughout the day. A Small Craft Advisory will likely
be needed after the nearshore warning expires.
