NEAR TERM. (Through Saturday) Issued at 323 PM EDT Fri Sep 18 2020

. Hard freeze for many tonight .

High impact weather potential: hard freeze for much of northern MI tonight.

1031mb high pressure centered over ne WI, and will creep across northern MI tonight. Some patches of cu are seen on satellite, mainly in eastern upper MI, near and w of CAD, and near Saginaw Bay. These will fade with loss of heating, and the next push of synoptic cloud cover will only reach eastern upper MI late tonight. So an excellent night for radiational cooling is ahead.

Earlier issued frost/freeze headlines look fine. Most of northern lower MI will be a few degrees colder than last night. Freeze warnings have thus broadened out a bit compared to last night; in particular extending all the way to Saginaw Bay. Frost advisories are up for only our most maritime zones. Lots of 20s for lows in the interior of northern lower MI, with near 30f to the mid 30s along the coastlines and in eastern upper.

Mid- and upper-level warm advection will get going toward morning, as the primary 500mb trof moves east across eastern Canada. Some associated mid and high clouds will arrive in eastern upper MI late tonight. A small slug of deeper moisture gradually works across Superior and adjoining land areas Saturday. This is forced by a compact shortwave digging into the mean upper trof. Clouds will continue to increase early Sat, with mostly cloudy skies in eastern upper MI, and partly cloudy as far south as M-72. Top-down saturation has a lot of low-level dry air to overcome, but there is a rather sharp uptick in forcing as the shortwave slides in. Chancy pops seem reasonable in eastern upper MI from late morning on, with the highest pops in Chippewa Co mid-afternoon.

Max temps mainly upper 50s to around 60f.

SHORT TERM. (Saturday night through Monday) Issued at 323 PM EDT Fri Sep 18 2020

High impact weather potential: Frost potential Saturday night.

Primary forecast concerns/challenges: Low temperatures Saturday night.

The upper level trough gets shunted off to the east later this weekend by a fairly large upper level ridge moving in from the west. So after one more possible frosty night Saturday night (mainly just patchy coverage as a return flow starts up), a warming trend is expected through the remainder of the short term. Skies should be mainly clear (perhaps mixed with some upper level smoke from the western states wild fires) through the period. Winds will become breezy as we get into return flow around the exiting surface high pressure system. Highs in the low and mid 60s Sunday will moderate into the mid 60s to the low 70s Monday. Lows generally in the mid 30s to low 40s Saturday night and the low and mid 40s Sunday night.

LONG TERM. (Monday night through Friday) Issued at 323 PM EDT Fri Sep 18 2020

High impact weather potential: Minimal.

The weather is expected to remain fairly quiet for the most part through the long term. Low pressure tracks by well to our north Monday night into Tuesday, dragging a moisture starved cold front across northern Michigan so no precipitation is expected with that system. Beyond that, there is fair agreement that a trough and associated cold front move across the region Wednesday night into Thursday. This system looks like it will bring chances for a few rain showers. Another upper level ridge approaches the region to cap off the work week. Temperatures are expected to be a few degrees above normal through Wednesday then cool off a bit to closer to normal to end the period/week.

AVIATION. (For the 18Z TAFS through 18Z Saturday afternoon) Issued at 103 PM EDT Fri Sep 18 2020

VFR, except for perhaps some fog at mbL late tonight.

High pressure in northern WI will push east across MI. This keep our wx cool but quiet. A touch of cu out there, but all cigs should remain VFR. However, there is a chance of some shallow ground/valley fog impacting mbL late tonight, much like it did this morning. Have occasional IFR vsbys for a few hours late tonight at mbL.

Northerly breezes will become light tonight.

MARINE. Issued at 323 PM EDT Fri Sep 18 2020

High pressure will cross northern MI tonight, with light winds. Sw winds will increase behind the high Saturday. Small craft advisories might be needed on at least some of our Lake MI waters by Sat afternoon, continuing into at least Sat night.

APX WATCHES/WARNINGS/ADVISORIES. MI . FREEZE WARNING from 2 AM to 9 AM EDT Saturday for MIZ016>018- 021>036-041-042-086-087-095-096-099. FROST ADVISORY from 2 AM to 9 AM EDT Saturday for MIZ020-088-097- 098. LH . NONE. LM . NONE. LS . NONE.
