LATEST UPDATE . Aviation

SYNOPSIS. Issued at 330 PM EDT Sat Apr 10 2021

- Band of showers and embedded storms this evening/tonight

- Showers near low over Southern Lower Sunday/Sunday night

- Chances for showers increase again Monday through Tuesday

- Drier second half of work week, temperatures closer to normal

DISCUSSION. (This evening through next Saturday) Issued at 330 PM EDT Sat Apr 10 2021

-- Band of showers and embedded storms this evening/tonight --

A band of showers and embedded thunderstorms will lift northward through Southwest Lower Michigan this evening and tonight. Everyone will see showers, but it will not be an all night rain in any one place as the band or precipitation will be migratory through the area. As for the threat of thunder, upper level diffluence is likely aiding the convection at this point as mid level lapse rates are quite poor and instability overall is limited. Plenty of lightning is noted, although most of it is within cloud. There should be pockets of rainfall tonight of 0.50 to 1.00 inches. This should not be an issue for us hydrologically.

-- Showers near low over Southern Lower Sunday/Sunday night --

Showers Sunday into Sunday night will focus closer to the upper low spinning across portions of Southern Lower Michigan. The upper low moves from Northern IN to near Toledo by Sunday morning. Best chance for showers will be across our southern 2-3 rows of counties, or generally near/south of Interstate 96.

-- Chances for showers increase again Monday through Tuesday --

Chances for showers at least continue in the Monday through Tuesday time frame if not increase. Another upper low drifts our direction from the west on Monday, which will act to keep troughing in place for the first couple days of the work week. We should see chances for showers continue both days. We have low pops at this point for showers and can see the need that we may need to increase pops with time.

-- Drier second half of work week, temps closer to normal --

Drier weather settles in for the second half of the work week as a surface high gradually nudges in from the north. We currently have a dry forecast going from Wednesday through Saturday. Highs through the period will drift back toward normal levels with 50s becoming common.

AVIATION. (For the 00Z TAFS through 00Z Sunday evening) Issued at 615 PM EDT Sat Apr 10 2021

A mix of mostly VFR/MVFR conditions is forecast tonight with MVFR at times due to low clouds and lingering showers overnight. An isolated thunderstorm cannot be ruled out tonight but potential for a storm is now too low to warrant inclusion in any of the terminal forecasts. Primarily MVFR conditions are expected at all the terminals Sunday morning and early afternoon due to low clouds and lingering showers.

MARINE. Issued at 330 PM EDT Sat Apr 10 2021

As a fairly deep low spins our direction this afternoon and evening from the south . north winds will increase on the north half of Lake Michigan. It appears at this time that a Small Craft Advisory is not needed as the stronger winds and waves remain out of our nearshore waters, more towards the open lake and Wisconsin side of Lake Michigan. From later tonight and through the rest of the weekend a baggy gradient is in place with the low nearby, so winds and waves will remain below SCA criteria.

GRR WATCHES/WARNINGS/ADVISORIES. MI . None. LM . None.
