NEAR TERM. (Through Tonight) Issued at 249 PM EDT Sun Apr 18 2021

. Not as cold tonight .

High impact weather potential: None.

Pattern synopsis and forecast:

Broad troughing remains centered across much of northeast NOAM, including the Great Lakes region, early this afternoon. Sharp shortwave trough digging southeast across southern Manitoba, with low pressure and its attendant cold front developing out ahead of it across Minnesota. Surface high pressure centered across our area, resulting in mostly to partly sunny skies and temperatures running about on par for were they should be for this time of year.

Overhead high pressure will push off to the east tonight as upstream wave and developing cold front make a run into the western Great Lakes by sunrise Monday. This system will bring some showers and another shot of chilly air into the region to kick off the work week.

Primary forecast concerns/challenges:

Temperature trends and addressing late night shower potential. Details:

Quiet evening expected, with just some increasing higher level clouds across northwest lower and eastern upper Michigan. Combination of those clear skies, light winds, and a still dry airmass should again allow temperatures to fall quickly, especially across northeast lower Michigan..where readings will likely drop into the lower 30s before recovering late. Good news is it appears our fruit crop vulnerable region along the northwest lower coastline should stay several degrees above freezing with a bit more wind expected in those areas. Clouds will continue to increase through the overnight as that upstream cold front pushes into the region . likely reaching vicinity northwest lower Michigan by sunrise Monday. This will likely drive a disjointed band of showers into eastern upper/northwest lower toward morning, with rain holding off for the remainder of the area until after sunrise.

SHORT TERM. (Monday through Tuesday) Issued at 328 AM EDT Sun Apr 18 2021

. Normal northern Michigan spring weather continues .

High impact weather potential: Freeze conditions possible.

Broad upper-level troughing will continue over the Great Lakes region with several different shortwaves/systems pinwheeling through with accompanying "cool shots". A developing clipper system will begin impacting the forecast area by Monday morning as a weak cold front associated with said system approaches the Great Lakes region. This will be a quick moving front and out of the area by Monday evening . leaving colder air on northwesterly winds in it's wake. With -10 to -12C 850mb temperatures, lingering moisture, and lake temperatures around 3C, we can expect lake clouds and even a few lake effect snow showers Monday night into Tuesday. Inversion heights between 4-5kft will suffice for some light to moderate snow bands to form with persistent northwesterly flow for several hours during the overnight and morning hours, but will begin to diminish in intensity and/or break up during the early afternoon hours as the diurnal heating breaks up any bands that have developed. Only minor accumulations (if any) are expected at this time. A mostly north to northwesterly flow will continue to usher in cold temperatures over the remainder of the forecast period. Temperatures are actually below normal for this time of the year . some locations will drop to about 10-15 degrees below normal, only reaching into the mid 30s to low 40s. Temperatures will be dropping into the low 20s to low 30s at night . with the possibility to get colder if clouds diminish and winds stay down in intensity. Will have to protect sensitive vegetation since a lot has blossomed and/or bloomed already . which is way too early, we still have a lot of cold nights in store for the next several weeks. The northwesterly winds Monday behind the aforementioned cold front will be gusty . with gusts up to 40-45 mph through the afternoon hours and right on into Tuesday morning . especially closer to the nearshore waters of the Great Lakes. The winds will veer a bit to the north and diminish in intensity by Tuesday night.

LONG TERM. (Tuesday night through Saturday) Issued at 328 AM EDT Sun Apr 18 2021

Broad troughing remains over the Great Lakes region . producing a few chances for precipitation, but no "big storms" at the moment. A large area of surface high pressure may develop over the Mid- Mississippi Valley region and build into northern Michigan . returning some warmer temperatures by the end of the next work week and into next weekend advecting in on southerly flow. Temperatures will generally be in the mid 40s to near 50 during the daytime hours and warm to near 60 by Friday. Overnight temperatures will drop into the mid 20s to low 30s.

AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 131 PM EDT Sun Apr 18 2021

Just some high based cumulus and higher level clouds into this evening. Clouds increase and lower toward Monday morning, potentially producing MVFR conditions with a band of light showers along a passing cold front. Some improvement expected heading through the latter portions of Monday morning. Light winds become gusty out of the west Monday morning.

MARINE. Issued at 249 PM EDT Sun Apr 18 2021

Winds become south to southwest tonight and gradually increase in speed ahead of a developing cold front . but should remain below advisory criteria until late. Winds become west to northwest and further increase in speed Monday into Monday night behind the passing front, producing both gales and small craft advisory conditions on our nearshore waters. The front will result in a band of showers which is expected to cross the region late tonight into Monday, with more spotty shower chances in many Lake Michigan nearshores and Whitefish Bay Monday night.

APX WATCHES/WARNINGS/ADVISORIES. MI . NONE. LH . SMALL CRAFT ADVISORY from 11 AM Monday to 6 AM EDT Tuesday for LHZ348-349. GALE WARNING from 5 PM Monday to 6 AM EDT Tuesday for LHZ345>347. LM .
