DISCUSSION
Issued at 342 AM EDT Tue Jun 18 2024

- Heat Advisory in Effect for Most of our Area

Hot and humid conditions are expected again today and tomorrow with continued south to sw flow waa and ridging in place. H8 temps of around 19-20 C with ample sun the next couple of days will result in high temps reaching the lower to middle 90s. This combined with dew pts well into the 60s to lower 70s will yield heat indices near 100 degrees. Therefore the heat advisory headline remains in effect for most of our area.

- Chance of Thunderstorms Today

A consensus of latest CAMs and 00Z HRRR all suggest that convection over our far northern fcst area early this morning will continue to drift ne and out of our area during the next hour.
Tranquil wx is then expected for most of the morning.

There is potential for an upper level disturbance and potential mcv over far southern IL/IN to move to the nne and potentially trigger convective development into our area by late morning. This will be something to monitor as we will have at least 1000-1500 j/kg of sb/mu capes in place with relatively strongest instability over our eastern fcst area.

Severe wx potential today looks low overall. However I would not rule out isolated strong to severe convection with moderate to strong instability this afternoon and model fcst soundings showing strong low level lapse rates. However deep layer shear remains low so this is mainly a pulse storm environment with potential for localized downbursts.

- Heat/Humidity Persists Through The Work Week

We see no need to change our headlines regarding the heat on the end time, which is currently 800pm Friday. 500mb heights remain high in the 590s dm through the end of the week. The 592dm 500mb height contour is all the way north of our entire forecast area at 18z on Friday and you do not see that very often. 850mb temperatures via the ECMWF, which is clearly the model to follow regarding temperatures as the GFS has been low as we have ramped into this heatwave, show values of +18C to +20C all the way into Friday. These values should continue to produce highs around 90 into the lower 90s potentially. We very much may need to extend the Heat Advisory into Saturday as that looks to be the warmest day potentially of the entire warm spell. 850mb temperatures spike to +22C. So, we are staying the course on the current heat headline. We urge folks to continue to check on people without air conditioning as there is no relief at night (we sit at 81 degrees at 320am this morning in Grand Rapids). Dew points are forecast to remain in the upper 60s to around 70 so heat index values will make a run at 100 each afternoon. The cumulative affect of the heat will add up as we continue to move forward.

- Small Chances for Precipitation Wednesday Night and Thursday

A weak front will move into the area from the north Wednesday night and Thursday with some small chances for showers and thunderstorms.
We do not think this will be enough to knock the heat down significantly and therefore no changes to headlines. The ECWMF hints at it and it may be the case where we do not see much in the way of precipitation from this front. The ridge will be fairly stout at that time with warm temperatures in the mid levels. Could see precipitation being less and less in the models as we approach Wednesday night and Thursday.

- Cooler Weather Behind a Cold Front Sunday

Models may be a tad quicker with the front that changes the airmass, not moving in potentially late Saturday night. Either way, we will see much lower dew points and cooler temperatures as we head into the latter half of the weekend. The front will come with a chance of showers and thunderstorms as it moves through. 850mb temperatures drop back into the lower teens C on Sunday/Monday which will be welcome after all the heat.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/
Issued at 725 AM EDT Tue Jun 18 2024

A weather disturbance will move through Southwest Lower Michigan today and bring mainly VFR clouds and scattered showers and thunderstorms. The timing on the showers and storms will during the afternoon after 17z to 18z. There may be some sprinkles that move in from an area of light rain before that, but currently this activity is not affecting visibility. All obs showing rain to our south at this time have 10SM visibilities. Ceilings will lower from unrestricted to 10,000 feet this morning and potentially to 4000-5000 feet this afternoon as showers and storms form. Tonight we expect conditions to dry out and remain VFR. Winds will be gusty from the southwest today at 10-20 knots with gusts to around 25 knots.

Issued at 342 AM EDT Tue Jun 18 2024

A small craft advisory and beach hazards statement is in effect for the northern half of the lakeshore from this morning through much of Wednesday. The southerly gradient will become sufficiently strong enough to cause wave heights to reach around 3 to 5 feet from Whitehall to Manistee. Wave heights will subside a bit late this week as winds weaken somewhat.
