SHORT TERM /THROUGH SUNDAY/
Issued at 357 PM EDT Sat Apr 19 2025
Short wave trough moving into the upper Lakes this afternoon...part of a larger positive tilt trough stretching from Hudson Bay southwest into Arizona. Decent pressure gradient across Michigan between low pressure over eastern Canada and a 1023mb surface high over Nebraska/Iowa/western Minnesota. Mainly cloudy skies across northern Michigan this afternoon with some thin spots over parts of eastern Upper and the surrounding Great Lakes. Broken area of rain/snow showers over western Upper spreading southeast into northern Lake Michigan.
Northern branch short wave trough swings through northern portions of the forecast area this evening as high pressure builds in from the west. Strong height rises (>80m/12h) and short wave ridging follows for Sunday...as slow moving southern branch short wave induces cyclogenesis over the southern Plains that tracks into eastern Kansas/western Missouri by Sunday evening.
Minimal weather concerns for Easter Sunday: Synoptically quiescent end to the weekend expected before things become more active for the start of the new work week. Expect cloud cover to eventually thin out with loss of heating though guidance is pretty bullish on this happening early and suspect it may take a bit longer. Will continue to watch showers coming out of western Upper and see if we end up with a little bit of this activity reaching the area around Grand Traverse Bay. May see some fog develop overnight but Sunday should start mainly sunny with clouds moving back in from the southwest during the afternoon. Rain chances may reach the M-55 corridor by late in the day but the bulk of the precipitation will arrive Sunday evening.
LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/
Issued at 357 PM EDT Sat Apr 19 2025
Low pressure currently near the Four Corners region will track northeast over the next couple of days, reaching the western Great Lakes Monday. This system will spread showers and embedded thunder into the region later Sunday night on into Monday evening. Rainfall amounts are expected to range from close to an inch across eastern upper to around a quarter of an inch near Saginaw Bay. Weak disturbances moving through a nearly zonal flow aloft will then lead to shower chances mid and late week. Not expecting widespread or long duration rains but there will be at least a chance for showers every day next week with the exception of Tuesday. Cooler temperatures are expected Tuesday followed by warmer temperatuers Wednesday into Thursday (highs ranging from the mid 50s to mid 60s)
then slightly cooler Friday and Saturday.
AVIATION /18Z TAFS THROUGH 18Z SUNDAY/
Issued at 140 PM EDT Sat Apr 19 2025
Widespread MVFR ceilings are expected to scatter out after 0000Z with high pressure building in from the west. This should also allow winds to go light...would think there is some potential for fog development overnight especially at KCIU given already small temperature/dew point spread. Any fog that does develop should mix out fairly quickly Sunday morning.
APX WATCHES/WARNINGS/ADVISORIES
MI...None.
MARINE...Small Craft Advisory until 8 PM EDT this evening for LHZ347- 348.
