.DISCUSSION...
Issued at 1259 AM CDT Thu May 28 2026

Canadian high pressure and an Omega Block pattern will bring a
long stretch of mainly dry weather to the region. Right now, only
small precipitation chances are expected with a back door cold
front Sunday night into Monday.

Temperatures will average well above normal through much of the
period, with highs mainly in the mid 70s to mid 80s. Right now the
warmest day of the upcoming week appears to be Friday when highs
are expected to soar into the middle to upper 80s. A few 90 degree
readings are not out of the question as probabilities are 40-60%
of hitting 90 or above across northern Wisconsin with a 10-30%
chance along and west of the Fox Valley.

Low afternoon relative humidity could lead to elevated fire
weather conditions; however, green-up continues across northern
Wisconsin and pine fuels have become less volatile. Therefore,
impacts may not be as significant as they would have been a couple
weeks ago.
