DISCUSSION...
A surface front has stalled over the Great Lakes overnight extending
from southern Lake Huron through southern Lake Michigan before it
curls back up to the north to connect to a deep, occluded surface
low tracking across northern Manitoba and Ontario today. This low
will draw the front back northward early in the day as a warm front
with weak high pressure then building up through the area with light
southwesterly flow in the warm sector to help boost temps today.
Still should be enough with plenty of late September sun to get SE
MI back into the low 80s. The fast moving system tied to the 130+
knot jet over Canada will then quickly pull the cold front through
the region late tonight into early Sunday morning. With ridging
aloft and the right exit region of the upper level jet passing over,
with warm mid levels producing a cap...expect the front to pass
through the area dry with only a boost in cloud cover owning to some
low level convergence and steep low level lapse rates to utilize the
little moisture present.
Another area of high pressure builds in on Sunday from the west
centering itself over the region by the late evening. Broad ridging
aloft over the central Plains into the Great Lakes will continue to
steer the jet well to the north through Canada. The strong flow and
several shortwaves acts to keep the ridge fairly low amplitude
initially, but a digging trough over the West Coast will help
amplify the ridge through the first half of the new week with the
ridge axis expected to reach the Great Lakes late Wednesday. A weak
backdoor cold front may drop through lower MI Tuesday, but will
really only act to allow high pressure over Ontario to build south
through the area flipping the surface winds around to the east on
the south side of the ridge. This will dry the area out even more
and knock temps down into the 70s, and possibly the 60s on Thursday,
keeping the newest dry stretch going through the week. The upper
level ridge continues to amplify through the end of the week which
eventually causes it to fold over through the region. The warmer
airmass under the ridge should slide in heading into the weekend
allowing temps to slowly climb back into the mid 70s.
