Issued at 629 PM CDT Wed Mar 29 2017

Updated for the new 00Z Aviation Discussion below.


.SHORT TERM...(This evening through Thursday)
Issued at 337 PM CDT Wed Mar 29 2017

The deep upper closed low over the southern plains will be the
weather maker south of the northland the next couple of days.
With the surface low skimming over Missouri tonight then Illinois
on THursday, the southern portions of our WI forecast area may get
clipped by a bit of precipitation. p-type could be a little
mixture later tonight and early Thursday morning otherwise, just a
little bit of rain. A ridge of high pressure originating over
Hudson Bay has been building into northwest MN where clearing has
been occurring. Expect this high to aid in overnight clearing
across at least northeast MN and maybe far northwestern WI. But
the low to south will keep clouds lingering over much of the rest
of northwest WI.

.LONG TERM...(Thursday night through Wednesday)
Issued at 337 PM CDT Wed Mar 29 2017

The extended period will remain relatively quiet with weak
shortwaves moving through the forecast region. The main item of
the extended will be in the above normal temps through next week.
High pressure will dominate the weather across Thursday night
through Saturday. Skies will be partly to mostly sunny with temps
in the 50s. A weak shortwave will move along the international
border bringing a low chance for rain or rain/snow mixed to the
north Saturday morning. Another area of high pressure will build
into the area later Saturday and will dominate the area through

Another weak shortwave will move through the region Sunday night
bringing another low chance for rain. There will be another break
on Monday before a warm front move north through MN on Tuesday and
Wednesday. This could bring the best chance for rain Tuesday
afternoon and during the day Wednesday. High temps through the
period will be mainly in the 50s with lower readings along lake


.AVIATION...(For the 00Z TAFS through 00Z Thursday evening)
Issued at 629 PM CDT Wed Mar 29 2017

The widespread VFR conditions across northeast Minnesota and
northwest Wisconsin will primarily continue through Thursday with
light southeast to east flow. However, there is a threat of some
lower clouds and visibility late tonight and early Thursday,
especially near KDLH because of more humid flow from Lake
Superior. Think the previous forecasts were a bit too aggressive
with IFR/MVFR conditions based on the latest model guidance, so
only have a short periods of MVFR conditions KDLH and KHIB. The
KBRD could be affected by the lower ceilings, too, but not as
confident to forecast MVFR at KBRD at this point.
