.the st marys river system has been reopened to vessel navigation... The united states coast guard in sault ste marie has reopened the st marys river system to navigation. The dense fog which affected the river system earlier in the day has now dissipated...allowing for safe navigation once again. Precautionary/preparedness actions... Dense fog was reducing visibilities to below 1 mile. Reduce your speed, and keep a lookout for other vessels, buoys, and breakwaters. Keep your navigation lights on. If not equipped with radar, you should consider seeking safe harbor. && lat...lon 4647 8412 4637 8414 4619 8408 4606 8395 4612 8382 4611 8378 4597 8392 4596 8400 4612 8417 4612 8423 4622 8437 4628 8430 4643 8436 4635 8456 4643 8468 4651 8462 4645 8448 4650 8442 4649 8427 4653 8422

328 pm edt Wed may 22 2019

Near term (through tonight)
issued at 311 pm edt Wed may 22 2019

More showers and possibly a thunderstorm...

high impact weather potential... None expected.

Primary forecast concerns... Pops.

A fairly deep but slowly weakening area of low pressure is centered
across west central minnesota. Another spoke of forcing (div-q)
moving out out of this system in combination with an approaching
weak cold front is expected to bring another round of showers
tonight. There could even be a rumble or two of thunder with a few
hundred j kg of mixed layer CAPE and precipitable waters of 1.50
inches or so. Gusty southeast winds will slowly diminish. It will be
kind of muggy with lows only in the middle 50s across northern lower
and the cooler middle and upper 40s across eastern upper.

Short term (Thursday through Saturday)
issued at 311 pm edt Wed may 22 2019
high impact weather potential: minimal. Still looking at the
potential for a few non-severe thunderstorms by later Friday.

Pattern synopsis: somewhat active pattern to close out this work
week as the western trough remains locked and loaded, sending
additional energy across the great lakes by later Friday. Still
dealing with the lead wave (the one responsible for today's
showers), expected to cut across the northern lakes on Thursday.

Both of these systems will be responsible for additional shower
chances, although that late Friday system definitely looks to be the
wetter of the two.

Primary forecast concerns challenges: temperature cloud trends and
addressing that earlier mentioned shower potential (as well as the
potential for a few rumbles of thunder to accompany those showers by
later Friday).

Details: mid level wave and its attendant surface low cut across
southern ontario northern lake superior Thursday morning. Attached
occluded front clears our area quickly just after sunrise. This
front is expected to fire off a band of showers along it tonight,
with these showers exiting stage right quickly during the morning.

Arrival of mid level wave cooler temperature aloft and hints of the
all-to-familiar eastern upper surface convergence axis within
favorable background west wind field suggests the potential for a
few more showers to develop up that way through the day. Some of
this activity may sneak down into the tip of the mitt counties of
northern lower as we head through the second half of the afternoon.

Otherwise, much of the area and most of the time looks to remain dry
Thursday. Conditions trend dry Thursday night as high pressure
temporarily builds into the region.

Energetic pattern out west continues, sending next wave up through
the northern plains and northern mississippi valley by later Friday.

Best mid level support no doubt passes to our west, but arrival of
attendant moisture plume and enhanced upper level support via intense
upper jet core suggests the potential for showers to spread across
the area Friday, with this shower threat continuing Friday night
through early Saturday as a cold front sweeps through the area.

Still some indication of the potential for a few embedded
thunderstorms by later Friday and Friday evening as plume of at
least a few hundred joules kg of elevated CAPE spreads north. Best
surface rooted instability looks to stay off to our south and
southwest, and thats where any severe weather threat looks to
remain. If current trends are realized, we are looking at dry
condtions by Saturday afternoon. Could be a rather warm Saturday,
all dependent on actual frontal timing and amount of showers clouds
during the morning.

Long term (Saturday night through Wednesday)
issued at 311 pm edt Wed may 22 2019
high impact weather potential: minimal.

Pretty quiet, albeit a bit cooler, condtions expected to finish out
the remainder of the memorial day weekend. Plenty of uncertainty on
what happens thereafter, with at least some hints of the next
western wave arriving Tuesday into Wednesday. Guidance consensus
blend continues to advertise this potential, and see no reason to
deviate from this idea just yet.

Aviation (for the 18z tafs through 18z Thursday afternoon)
issued at 136 pm edt Wed may 22 2019
low pressure in the plains will lead to gusty winds through the
taf period. There will also be a few showers, mainly tonight.

MVFR CIGS and possible fog will form late tonight... Along with low
level wind shear.

Marine
Issued at 311 pm edt Wed may 22 2019
stacked low pressure in minnesota with push a warm front into nrn
michigan this evening. Then, this low pressure and it's cold front
crosses later tonight and Thursday morning. High pressure settles
back in for Thursday night. The tight pressure gradient will
continue to lead to small craft advisory winds for most nearshore
zones through this evening. Another round of showers expected
tonight with a rumble or two of thunder also possible.
