.DISCUSSION...(Today through next Tuesday)
Issued at 330 AM EDT Wed Sep 2 2020
-- Showers end this morning then clearing by noon--
A jet educed frontal wave moving through this area early to mid
morning is bringing and area of showers, some heavy north of a
Muskegon to Mount Pleasant line. There is only marginal
instability with the greatest instability over Lake Michigan. A
40 knot low level jet tracking east northeast, north of Muskegon
by 5 am will be east of Lake Huron by 10 am this morning. So, the
the axis of the low level jet north of I-96, that is where most of
the rain will be between now and say 8 am. Rainfall amounts west
of US-131, and north of Big Rapids may approach an inch is
isolated locations before it comes to an end.
Areas near I-96 and maybe as far south as I-94 likely will see a
period of showers during the mid morning. These showers will move
to toward I-69 by mid to late morning.
Behind the area of showers is a sharp clearing so all areas should
have mostly sunny skies by early to mid afternoon. Since there is
not really any significantly cooler air behind this front, highs
should be in the mid to upper 70s in most locations.
High pressure moving over the area tonight means clear skies and
light winds, through the winds may ramp up toward morning as the
next system will begin to impact our area before sunrise.
-- Cold front brings windy conditions Thursday and cooler
Friday--
The next system is very strong surface low (upper wave goes
negative tilt) and tracks a 980 mb surface low east northeast near
50N. That is so far north that we do not get much mid level
moisture with this frontal system, so rain seems rather unlikely.
On the other hand, we sure do get the wind with this frontal
passage. At this point is does not look like advisory criteria
winds inland but I could see gusts to near 35 mph. It will be warm
too, highs should be near 80. The cooler air moves in Thursday
night and remains in place Friday. Highs will struggle to make 70
on Friday.
-- A storm system brings showers and thunderstorms by Sunday--
The next upstream system looks more impressive than the Thursday
system and should move into the area by Sunday. The surge of warm
air ahead of the system should bring showers and thunderstorms to
the area by Sunday
--Cooler weather expected by early next week--
The colder air follows by Monday but there is some question as to
what happens to the trailing shortwave, does it close off an upper
low over the western states or dig a very deep eastern trough? If
the GFS version of this happens it will be a very wet and chilly
week.
&&
.AVIATION...(For the 12Z TAFS through 12Z Thursday morning)
Issued at 645 AM EDT Wed Sep 2 2020
IFR cigs with showers will track east across the CWA this morning
with the front. I am not expecting any thunderstorms at this time.
At any one location the IFR/MVFR conditions should not last more
than 4-5 hours. Once the front comes through skies should clear
within an two hours. Most of the afternoon will be clear or nearly
so. The clear skies (below 20,000 ft) will continue into tonight.
Winds will be gusty today but diminish this evening.
&&
.MARINE...
Issued at 645 AM EDT Wed Sep 2 2020
I have reissued the Small Craft Advisory and added a Beach Hazard
Statement to the mix for today. Wave heights were increasing at
all of our buoy sites over the past hour or so. Ludington has
increased to 4.3 feet, Muskegon and Port Sheldon were up to 3.6
feet and still increasing. Due to the west winds persisting all
day we expect the 3 to 5 foot waves to continue through the day.
Winds are expected to decease for a few hours during the evening
only to increase again after midnight. Added headlines will likely
be needed for Thursday.
