Area forecast discussion, Sep 2, 3:47 AM EDT, 2 hours 51 minutes before
Area Forecast Discussion National Weather Service Grand Rapids MI 347 AM EDT Wed Sep 2 2020 LATEST UPDATE... Marine .SYNOPSIS... Issued at 330 AM EDT Wed Sep 2 2020 - Showers end this morning then clearing by noon - Cold front brings windy conditions Thursday and cooler Friday - A storm system brings showers and thunderstorms by Sunday - Cooler weather expected by early next week && .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 instabilitywith 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 06Z TAFS through 06Z Wednesday night) Issued at 140 AM EDT Wed Sep 2 2020 A band of showers with MVFR/IFR cigs is approaching our TAF sites from the west at I write this. The front will come through the area just after sunrise, but prior to that there should be 3 to 4 hour period of MVFR/IFR cigs at all of our TAF sites. The area of shower, which is currently nearly a solid area of showers from easter Upper Michigan, across eastern Wisconsin into central Illinois is expected to weaken considerably by the time it crosses our TAF sites around 12z (more or less). I put the showers in the MKG and GRR TAF sites only as I do not think the showers will last long enough to impact the other TAF sites. Once the front comes through skies will clear, winds will turn northwest and become gusty. Skies should remain clear Wednesday night but winds will diminish to under 10 knots by sunset. && .MARINE... Issued at 347 AM EDT Wed Sep 2 2020 We earlier through the frontal wave would briefly increase winds to 20 to 30 knots north of Muskegon between 2 am and 6 am but that does not appear to be the case so I have expunged the headline. Winds behind the weak cold front today will increase to 10 to 20 knots from the west to northwest. That will result in 2 to 4 foot waves. High pressure will move across the near shore this evening decreasing winds but as the high moves to the east of Michigan later at night wind will turn to the south and increase to 15 to 25 knots toward morning. A fairly impressive storm system (982 mb low) will track east near 50N on Thursday. That results in a very strong pressure gradient with the 1020 mb high over Kansas, so winds will increase to 20 to 30 knots from the south and southwest during the day Thursday, we may need gale warnings over northern sections. The cold front comes through by midday Thursday, which turns winds to the west then northwest. Our storm deepens to below 980 mb (ECMWF). This should keep strong winds going into the Thursday night. We will have to look at that more closely on the day shift for possible headlines. && .GRR WATCHES/WARNINGS/ADVISORIES... MI...None.
