Area Forecast Discussion
National Weather Service Duluth MN
353 PM CDT THU JUL 7 2016

.SHORT TERM...(This evening through Friday)
Issued at 353 PM CDT Thu Jul 7 2016

Things are evolving fairly rapidly as of mid afternoon as strong
deep layer forcing from the upper trof in the Dakotas continues to
overspread much of MN. Thunderstorms continue to expand in
coverage and intensity from the Red River Valley in northeast
ND/northwest MN south-southeastward into west central MN. This
area of thunderstorms will continue to expand and rotate
northeastward into much of northern MN this evening and overnight.

While there will be a risk of strong or severe storms this
evening, the primary story with this system seems to be trending
toward heavy rainfall across much of northern MN tonight and
Friday morning as strong deep-layer forcing for ascent spreads
across the main precipitable water/CAPE axis with increasingly
better inflow with time tonight and also maintains for a rather
long duration. Flash flood guidance is somewhat low, however, and
much of the main area at risk is also very boggy, which has a
tremendous capacity to store water. So, at this point, we are
cautiously optimistic that hydrology issues will not become a
major concern, but there certainly could be problems in some areas
with low water crossings or in towns where drainage is more
confined.

.LONG TERM...(Friday night through Thursday)
Issued at 353 PM CDT Thu Jul 7 2016

The next system to affect the Upper Mississippi Valley can easily be
seen on water vapor off the Pacific Northwest coast/Gulf of Alaska.
This upper trough will dig into the Northwestern U. S. and give the
Northland an extended period of rain chances.

The first round will possibly be Saturday night and into Sunday as
the first of many shortwaves is ejected from the trough and moves
quickly into northern Minnesota. Some showers are possible as the
wave travels through the upper ridge. For now kept the chance of
showers in the western portion of the forecast area where the
strongest lift associated with the upper system and baroclinic
zone will be. However, we cannot rule out showers elsewhere,
especially over northern MN. Through most of next week the low
pressure system, which becomes vertically stacked, will affect the
northland as it spins across the southern Canadian provinces. The
long range models handle this system very well, although by the
end of the forecast period the ECMWF is much more progressive than
the GFS.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1239 PM CDT Thu Jul 7 2016

VFR conditions will quickly deteriorate late this afternoon and
this evening to MVFR and pockets of IFR as low pressure and a
frontal system spread rain and thunderstorms into the forecast
area. There will be slow improvement in ceilings/visibilities
after 12z, but confidence is low for improvement to VFR.
