SHORT TERM. (Issued 200 PM CDT Thu Jul 29 2021)
Tonight through Friday night:
A ridge of high pressure will dominate this period with dry and quiet conditions. Winds will remain onshore through Friday. As the high slips to the east Friday night a weak return flow sets up. A cooler and less humid regime will be in place as well.
LONG TERM. (Issued 200 PM CDT Thu Jul 29 2021)
Saturday through Saturday night:
Increasingly cyclonic mid level flow regime along with a southward dropping cold front should result in some shra/tsra activity Saturday afternoon and evening. 0-6km shear is proggd to be near 30 knots or slightly higher though mid level lapse rates not overly impressive. Some CAPE is proggd to buildup ahead of the front. So will maintain the potential for some afternoon/evening convection.
Sunday through Thursday:
High pressure is proggd to meander across the Upper Midwest and then finally towards the end of the period be off to our east with a return flow setting up. For now will stick with the init pops and keep things on the quiet side.
AVIATION. (Issued 200 PM CDT Thu Jul 29 2021)
Lingering MVFR CU field should gradually dissipate this evening. Winds will be largely northeast this period of the surface high building into the Dakotas.
MARINE. (Issued 200 PM CDT Thu Jul 29 2021)
Will keep the small craft advisory intact with the northeast winds and building wave action. Conditions gradually improve on Friday as the center of the high comes overhead.
BEACHES. (Issued 200 PM CDT Thu Jul 29 2021)
There is a Beach Hazard Statement in effect tonight into Friday morning for the Lake Michigan beaches from Sheboygan County south to Kenosha County. This is due to north to northeast winds and waves of 3 to 5 feet.
