KEY MESSAGES

- Rain/snow chances this afternoon through Saturday, with the potential for graupel to mix in with any heavier showers.

- Cooler than normal temperatures through the middle of next week but no high impact weather expected.

SHORT TERM /THROUGH SATURDAY/
Pattern Synopsis/Forecast: Closed upper-level low pressure continues to spin across northern Ontario with broad/amplified troughing draped across the Great Lakes and upper MS Valley. Attendant surface low expected to follow suit to the northeast into Quebec by this evening. Initial cold front already east of our area with a secondary front expected to cross northwest to southeast later tonight into Saturday morning.

Forecast Details: Partly sunny skies across much of northern lower this afternoon with more cloud cover north of the bridge in closer proximity to the aforementioned surface low. Relatively steep lapse rates and increasing low-level moisture already supporting showers developing this afternoon across eastern upper. These showers perhaps mixed with graupel and/or snow at times into the overnight hours. Those chances spread across northwest lower and the tip of the mitt this evening and overnight with lower probabilities across northeast lower and especially near Saginaw Bay. Any snow accumulation likely minimal with some locations perhaps picking up a coating to a few tenths of an inch. Low temps tonight generally within a couple of degrees on either side of freezing -- coldest inland from the Great Lakes.

A similar story anticipated for Saturday with at least low chances for showers continuing under partly to mostly cloudy skies. While afternoon highs likely reach into the low-mid 40s area-wide, some snow mixing in remains a possibility, especially for the typically cooler/interior spots. Again, a minor accumulation not entirely out of the question, although with little impact expected.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/
Still expecting a breezy and cool weather pattern across the region over the next several days as a trough becomes established across northeast Canada. Do expect this trough to eventually give up the ghost late next week leading to warming temperatures. Looking farther ahead, above normal temperatures are expected for the last few days of the month. Precipitation chances in the long term are limited to Monday night into Tuesday night from a short wave moving in off of the Pacific and Friday via warm air advection. A majority of the upcoming low temperatures (with the exception of perhaps Monday night) will be at or below freezing with at least a couple of nights potentially as low as the low and mid 20s.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/
Largely VFR expected through the TAF period with the possible exception coming late tonight into early Saturday morning with low probabilities for MVFR CIGs -- primarily at CIU/PLN.
Scattered rain/snow showers return to CIU this afternoon with lower probabilities at northwest lower MI terminals tonight into Saturday. Occasional gustiness this afternoon to near 30 kts.
