Area Forecast Discussion
National Weather Service Duluth MN
337 PM CDT Sat Oct 14 2017

.SHORT TERM...(This evening through Sunday)
Issued at 337 PM CDT Sat Oct 14 2017

Surface low pressure in the Central Plains will deepen over Iowa
this evening then continue northeast through Michigan toward Lake
Huron by 12Z Sunday. The low will then continue to pull away from
the region Sunday. An upper level trough will be moving east through
Minnesota into Wisconsin tonight with a weaker shortwave moving
through the Northland on Sunday. An area of strong FGEN forcing will
develop tonight and lift north into parts of northern Wisconsin and
Minnesota. Latest radar was showing an area of increasing echoes
from western Minnesota into north central Minnesota in line with the
developing FGEN. Temperatures this afternoon were in the upper
forties to middle fifties. Rain will increase in coverage across
much of the region through the evening becoming widespread for most
areas. The airmass will cool overnight due to cold air advection and
dynamic and evaporative cooling processes. The rain will mix with or
change over to snow by late evening over portions of northern
Minnesota, mainly north of Highway 2 then progressing southeast
toward Aitkin, the Twin Ports, and Moose Lake areas by late tonight
and even parts of northern Wisconsin around sunrise. The best chance
for light accumulation will be over northeast Minnesota with parts
of the Arrowhead receiving around an inch.

Mainly light rain will continue early Sunday morning over northern
Wisconsin with chances highest across northern Ashland/Iron Counties
where there will be lake processes ongoing. A weaker shortwave will
be moving through in northwest flow aloft. Skies will turn
partly/mostly sunny for a time but clouds will then be on the
increase from west to east with the wave. There may be enough
forcing for some light rain over parts of northern Minnesota but any
rain amounts should be light. We expect highs from the upper forties
to lower fifties, warmest in northwest Wisconsin.

.LONG TERM...(Sunday night through Saturday)
Issued at 337 PM CDT Sat Oct 14 2017

An upper-level ridge over the western Great Lakes will move
eastward out of the region Sunday night with rising heights and
surface high pressure building. In the wake of the trough a quasi-
zonal flow pattern will establish and persist through the week.
Several shortwaves will cruise through the Canadian Prairies but
should only result in an increase in cloud cover over the
Northland. Temperatures will trend gradually warmer through
Friday. Above to much above temperatures are expected with highs
in the 50s on Monday rising to the low 60s to near 70 degrees by
Friday.

&&

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1248 PM CDT Sat Oct 14 2017

Developing low pressure over Kansas will quickly lift
northeastward through the Upper Midwest tonight through Sunday
morning. Precipitation to the northwest of the low track will
continue to develop over the next 2 to 6 hours and spread across
the terminals through this evening. Rain is expected for most of
the sites, with a potential for snow aloft. There is a chance a
rain/snow mix will reach the surface at DLH and HIB for a short
time overnight. Have included the mix in the forecast for DLH, but
still less than confident regarding timing at HIB and have
maintained all rain there. Precipitation will taper off fairly
quickly overnight departing HYR around 11Z.
