SHORT TERM. (Issued 349 PM CDT Thu Sep 23 2021)

Tonight through Friday night:

Precip brushing the far northeast will wind down by early evening, with decreasing clouds and winds overnight. This will allow temps do drop into the 40s most places once again.

A strong shortwave and cold front will move through the area later Friday into Friday night. Precipitable water should get up to around an inch ahead of the front, with some decent forcing as this system moves through. Moisture and forcing look even a bit better now than models were showing 24 hours. Seems like a good bet for some showers, mainly late in the afternoon and evening. Instability looks a tad better, so kept a small chance for thunderstorms. Temps will be warmer Friday with southerly winds expected ahead of the front. Southerly winds will gust 25 to 35 mph ahead of the front as well.

DDV

LONG TERM. (Issued 349 PM CDT Thu Sep 23 2021)

Saturday through Thursday:

It will be cooler and dry Saturday behind the departing system. It then looks mainly dry and milder for the first half of next week. The main question for early next week is still how much the upper ridge will lean into the area vs staying in a troughing pattern. Models overall have trended more towards the ridge, suggesting near to above normal temps for this period. Onshore winds most days will result in cooler conditions near the lake.

DDV

AVIATION. (Issued 349 PM CDT Thu Sep 23 2021)

VFR conditions are likely to continue into Friday. Gusty northerly winds will become lighter this evening and overnight. Breezy southwest winds will develop ahead of an approaching low and cold front by later Friday, with showers expected late afternoon and into the evening as the front moves through. A few rumbles of thunder will be possible as well. Winds will become breezy out of the west behind the front Friday evening.

DDV

MARINE. (Issued 349 PM CDT Thu Sep 23 2021)

Low pressure over southeast Michigan will progress to just north of Lake Huron by Friday morning, weakening slightly as it continues northward. Strong northerly winds will continue to gradually ease from north to south this afternoon and evening. High waves will slowly subside through tonight as well.

After a brief period of lighter winds, southerly winds will increase Friday afternoon ahead of low pressure trough over Upper Michigan and northern Wisconsin. There is a chance for southerly gales across the southern open waters as the trough swings across Lake Michigan Friday evening. Small Craft Advisory conditions are expected for the nearshore waters tomorrow afternoon and evening. High pressure will then through the Midwest and Ohio River Valley Saturday into Sunday.

DDV

BEACHES. (Issued 349 PM CDT Thu Sep 23 2021)

Strong northerly winds will gradually ease into this evening, with waves of 4 to 8 feet lingering at Lake Michigan beaches. Dangerous currents will are likely and conditions will continue to be dangerous for even the strongest of swimmers. Swimming is not advised until conditions improve going into Friday.
