We`re enjoying a little break in the active weather of the past two
days as yesterday`s system spins to the north over Ontario.
Rainfall totals across the area generally range from 2-4 inches
since Monday, with lower totals out west. Breezy west/northwest
flow is keeping temperatures in the low to mid 60s early this
afternoon with a nice diurnal Cu field across the area. A few
isolated showers have popped up over the last hour or so across
central Minnesota and western Wisconsin with the 500mb trough
still lingering in the area. These showers will remain fairly
isolated in nature, but may produce some small hail and gusty
winds before diminishing by sunset. Southerly flow returns for
tomorrow ahead of a low over the Dakotas, allowing for WAA and
moisture to advect back into the region. Temperatures will make
a run at 80 ahead of the cold front, but the timing of the
frontal passage looks to be late Thursday night, missing the
best window of instability. Still, a few stronger storms with
hail and gusty winds are possible tomorrow night into early
Friday from western into central Minnesota with most thunder
potential decreasing by the time the line reaches eastern
Minnesota and western Wisconsin Friday morning. QPF amounts are
on the order of a quarter to a half inch, with locally higher
amounts possible.

Heading into the holiday weekend, temperatures look to be in the
upper 60s to low 70s with daily slight chances for showers as an
upper low is parked north of us. This weekend does not look to be a
washout by any means at this point, with very low QPF amounts
overall. A stronger embedded wave looks to swing through on Sunday,
which will lead to the highest chances for scattered showers and
storms, particularly across the southern half of the forecast area.
It`s not until sometime Tuesday that this low finally moves out and
we see slightly warmer temperatures and drier conditions return
by the middle of next week.

VFR conditions through the period with SCT/BKN cumulus through
sunset. Isolated showers are expected to develop later this
afternoon, mainly along & north of Interstate 94, but the
probability of rain impacting any one terminal (10-20%) is too
low to include a mention in the TAF. A few instances of
lightning are also possible with any of the showers this
afternoon. Westerly winds will gust to 25-30 kts this afternoon,
with speeds diminishing towards sunset & eventually dropping
below 5 kts by 01-02Z. Winds back from southwesterly to
southerly overnight into tomorrow morning.

KMSP...Can`t rule out an isolated shower or thunderstorm late
this afternoon in the vicinity of the terminal. Any impacts
would be brief.

FRI...VFR/MVFR with -SHRA/TSRA likely. Wind SE 10-20 kts,
becoming W 15-25 kts during the afternoon.
SAT...VFR. Wind SW 10-15 kts.
SUN...VFR. Wind E 10-15 kts.
