LATEST UPDATE . Synopsis/Discussion/Marine

SYNOPSIS. Issued at 330 AM EDT Thu Sep 16 2021

- Dry through Friday

- Showers/storms possible Friday night into Saturday

- Warmer Then Normal Temperatures Ahead

DISCUSSION. (Today through next Wednesday) Issued at 330 AM EDT Thu Sep 16 2021

-- Dry through Friday --

High pressure will continue to build over the region today into tomorrow. This will allow for a mild and dry pattern through the rest of the work week.

-- Showers/storms possible Friday night into Saturday --

As the ridge of high pressure moves eastward, a trough will trek through the region. This will bring a frontal pattern that the NAM is showing to have a slightly better chance of precipitation then previous model runs. There is better surface convergence, along with mid to upper level instability. Model soundings continue to show a dry layer aloft. This should stall incoming precipitation. However, the line of showers and storms should move into the region Friday night into Saturday morning. NAEFS mean PWATS continue to show the trend of decreasing moisture as the system reaches SW and central Michigan. So while POPS will be increased there is still little QPF associated with this system.

-- Warmer Then Normal Temperatures Ahead --

The southerly flow will continue with an entrainment of warm, moist air through next week. This will bring max temperatures of 10 to 20 degrees above normal Sunday into mid week. It will also bring an increase in shower and storm potential by Tuesday due to the tropical air mass. NAEFS shows +1 to +2 anomaly across the Great Lakes Monday into Tuesday. So there is a greater potential for widespread showers Monday night into mid week.

AVIATION. (For the 06Z TAFS through 06Z Thursday night) Issued at 153 AM EDT Thu Sep 16 2021

The biggest aviation concern overnight will be the patchy fog at JXN and LAN. With cold overnight lows and calm winds there will be enough low level moisture for periods of LIFR to IFR vsbys at JXN and LAN between 06Z to 12Z. Conditions will improve quickly after sunrise with VFR dominating otherwise.

MARINE. Issued at 330 AM EDT Thu Sep 16 2021

Latest models continue to show a good signal that there could be advisory conditions late Thursday night into Friday for potentially hazardous conditions developing on Lk MI north of Whitehall. Guidance suggests a period of stronger southerly flow in this area ahead of an approaching frontal boundary over Wisconsin. Winds shift northeasterly behind the front and high pressure builds in for Saturday. Increased southerly flow is expected to develop again early next week.
