LATEST UPDATE . Aviation
SYNOPSIS. Issued at 328 PM EDT Sun Sep 19 2021
- Upper Troughing Moves East with Heavy Rain Tuesday and showers lingering into Thursday
DISCUSSION. (This evening through next Sunday) Issued at 328 PM EDT Sun Sep 19 2021
There is better forecast confidence today in the details as models are converging towards the sharp trough axis cutting off into an upper low and troughing persisting across the Great Lakes region through the end of the week.
We have been watching Gulf moisture that is the remnants of a tropical cyclone slowly moving northward the past couple days. A line of showers and thunderstorms across southern Indiana this afternoon mark the leading edge and the CAMs forecast showers to reach southern Lower Michigan Monday morning and spread north across the forecast area by afternoon. Coverage is expected to be less than currently seen, but precipitable water values spike up to over 1.5 inches by late afternoon and heavy rainfall rates are possible with any deep updrafts. SHear profiles are weak and severe weather threat is low.
Surface cold front plods across the forecast area from west to east on Thursday morning and afternoon. We expect basin average rainfall of around an inch with some 2 inch amounts possible across the southeast forecast area. Rivers should be able to handle this as they are near their lowest levels of the year.
Upper low lingers on Thursday with scattered showers and temperatures stuck in the 50s as much cooler air is drown south and clouds and showers prevent much in the way of warming. The upper low departs by the weekend with generally fair but cool weather through Sunday.
AVIATION. (For the 00Z TAFS through 00Z Monday evening) Issued at 738 PM EDT Sun Sep 19 2021
High confidence for VFR conditions at all terminals through 06Z tonight. The only change of note compared to the 18Z TAF issuance is that some detail was added regarding the expected transition to MVFR and then IFR ceilings during the day Monday. Precipitation on Monday will start affecting terminals later in the day. Rain that occurs could be accompanied by significant drops in visibility, especially since wind gusts well over 20 knots are expected too.
MARINE. Issued at 328 PM EDT Sun Sep 19 2021
South winds ramp up on Monday with gales expected north of Holland by Monday evening, so we will have a Gale Warning for that area into Tuesday morning. There could be a lull Tuesday afternoon but winds and waves may be hazardous to small craft through Thursday.
