LATEST UPDATE . Aviation

SYNOPSIS. Issued at 135 PM EDT Thu Jul 29 2021

- Chance of strong to severe storms Saturday along cold front

- Upper Troughing brings cool weather with occasional showers

DISCUSSION. (This evening through next Thursday) Issued at 128 PM EDT Thu Jul 29 2021

- Chance of strong to severe storms Saturday along cold front

Northerly flow will bring cooler and less humid air into Friday afternoon, then southwest winds will advect in some moisture ahead of a cold front moving in from the north as a shortwave trough reinforces upper troughing across the eastern U.S.

Forecast soundings show 25 to 30 knots of deep layer shear along with marginal instability and downdraft potential. Isolated downbursts and hail appear to be the main threats with multicell cluster storm mode from Saturday afternoon into the evening.

- Upper Troughing brings cool weather with occasional showers

Surface cold front clears Lower Michigan early Sunday with the persistent western ridge/NE trough pattern seeing an expansion of the trough across the eastern U.S. including the Great Lakes. This will mean cooler than normal temperatures with occasional chances for showers as smaller scale features move through the upper troughing.

AVIATION. (For the 00Z TAFS through 00Z Friday evening) Issued at 705 PM EDT Thu Jul 29 2021

Added VCSH mention to JXN until 0100z as a few showers have developed near LAN along a cold front that is moving southward. Lightning is a low possibility at JXN but left it out given we are running out of diurnal instability across southern Lower MI. VFR will dominate this TAF period for all sites.

MARINE. Issued at 135 PM EDT Thu Jul 29 2021

No changes planned to the marine hazards with winds and waves expected to diminish overnight. There could be some higher waves on Saturday with southwest winds ahead of the cold front and again Sunday behind the cold front. Thunderstorms along the cold front could bring strong, gusty winds Saturday afternoon or evening.
