Area Forecast Discussion National Weather Service Grand Rapids MI 335 PM EDT Thu Jul 21 2022 LATEST UPDATE... Discussion/Marine .DISCUSSION...(This evening through next Thursday) Issued at 257 PM EDT Thu Jul 21 2022 ...Risk for a few thunderstorms this evening... A 850/700 mb trough dropping southeastward through WI is forecast to track through the CWA this evening. Surface based instability values of around 1000 to 1500 J/kg exist out ahead of this feature...especially toward Holland and Kalamazoo. Forecast soundings show an inverted V look to them and DCAPE is over 1000 J/kg. These two parameters/features support strong wind gusts with any stronger cell. Forecast low level convergence favors the area generally south of a Muskegon to Grand Rapids line for the most shower/storm activity. This is where we will feature the highest POPs. ...Additional showers and thunderstorms possible late Friday night... The latest runs of the models appear to focus the main storm activity just southwest of the CWA late Friday night. The low level jet and stronger instability is shown to be aimed in those locations. Still...some deep moisture and weak instability is shown for southwest parts of the CWA which will allow for at least scattered showers and thunderstorms. Close monitoring will be needed going forward as a northward shift of the low level jet and instability could lead to an increase in the storm coverage for the CWA. ...Numerous showers and storms look likely for Saturday night into early Sunday... An unseasonably strong mid to upper level wave will be tracking eastward through the Canadian Prairies and into Ontario. On the south side of this feature...the mid to upper level flow strengthens over the Great Lakes Region. At the same time a strong southwesterly low level jet will be moving into the Great Lakes Region and advecting in abundant moisture. Deep layer shear will be quite strong through the night. As a result of all this...one or more MCS's look possible in this window with an increased risk for severe weather. In addition with PWAT values forecast to climb up over 1.75 inches locally heavy rain is likely. If the storms repeat over the same area...some flooding may occur. The low level jet and instability gradient shift south and east of the CWA by 18z Sunday so much less in the way of storm coverage is forecast by then. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 146 PM EDT Thu Jul 21 2022 With a relatively tight pressure gradient in place and deeper surface based mixing occurring...gusty winds have developed. Values in the 20 to 25 knot range have been recorded. These gusty winds will continue through much of the afternoon...but weaken gradually through sunset. That is when showers and a few thunderstorms will develop. The most favorable location for the convection is around KAZO and KBTL which is where the low level wind convergence and instability may combine to generate the thunderstorms. There is some uncertainty on this potential so aviators should continue to monitor trends through the afternoon. Any shower or thunderstorm could contain localized gusty winds. Later in the evening and more so after midnight any showers to thunderstorms will dissipate. The winds will also weaken as the pressure gradient and mixing depth decrease. && .MARINE... Issued at 257 PM EDT Thu Jul 21 2022 The pressure gradient tightens up across the northern zones later Friday into Friday night as a wave of low pressure tracks eastward through the northern Great Lakes Region. Southwesterly winds will increase...especially for Little and Big Sable Points by Friday evening. Hazardous conditions for small craft and swimmers may develop. && .GRR WATCHES/WARNINGS/ADVISORIES...
