Area Forecast Discussion National Weather Service Gaylord MI 732 PM EDT Thu Apr 22 2021

NEAR TERM. (Through Tonight) Issued at 329 PM EDT Thu Apr 22 2021

. Clearing but not as cold tonight .

High Impact Weather Potential: None for now.

Pattern Synopsis/Forecast: Afternoon composite analysis reveals short-wave ridging building across the Midwest and into the western Great Lakes with a fair amount of dry air (PWAT values generally under three tenths of an inch) across the region. Sprawling surface high pressure spans the lower Mississippi/Gulf Coast states with ridging stretching up through the western Great Lakes. Earlier mid level short-wave feature is east of the region and has taken much of the cloud cover with it. Had a robust amount of Cu/StCu blossom across the forecast area earlier in the day. Took awhile, but heating and deep mixing has finally thinned/ cleared out most the clouds with SCT-BKN conditions still lingering east of M-33 and a small portion of eastern Upper MI.

Short-wave ridge axis shifts eastward and nearly overhead by Friday morning with warmer air aloft finally making solid inroads into the region. This *should* finally lead to mainly clear skies for all areas tonight. We will retain a bit of a sfc pressure gradient with low level winds increasing off the surface as we go through the night. So despite the clear skies, we will not get as cold tonight as we have the last few, although our normally cold inland spots will likely dip into the upper 20s. But areas along the NW Lower MI shoreline with Ag concerns should remain a few degrees above/below freezing. Thus, we're not anticipating the need for a freeze warning.

SHORT TERM. (Friday through Sunday) Issued at 329 PM EDT Thu Apr 22 2021

. Warming Temperatures then Temporarily Turning Colder Again .

High impact weather: Possible freezing nighttime temperatures Saturday night could damage the cherry and other crops.

Primary forecast concerns/challenges: Temperatures and Pops.

The upper level ridge axis progresses across the region Friday morning with a warmer return surface flow developing behind it. In addition, expect an increase in high clouds in the afternoon. Another short wave moves into the region late Friday night into Saturday and combines with an approaching surface cold front to bring a chance for rain showers Saturday into Saturday evening. Although model soundings indicate that the above freezing layer extends up to about 4000 feet, can not totally rule out a mix with a few wet snowflakes late Saturday night behind the front though lots of dry air arrive coincidentally with the cold air. Highs Friday of well into the 50s to around 60 and perhaps not quite as warm Saturday mainly due to a decent amount of cloud cover and the possible showers around. Could see freezing temperatures threatening fruit trees once again Saturday night but with breezy winds and lingering cloud cover we might get by unscathed (will continue the mention for now). Much cooler and a bit blustery Sunday with lingering clouds giving way to increasing sunshine. Cold air advection through a good part of the day is expected to lead to high temperatures struggling into the 40s to around 50.

LONG TERM. (Sunday night through Thursday) Issued at 329 PM EDT Thu Apr 22 2021

. Warming Up Once Again .

High impact weather potential: Possible freezing nighttime temperatures could damage the cherry and other crops Sunday night.

Surface high pressure moves across the region Sunday night bringing another chilly night. This setup should allow temperatures to drop off fairly well possibly impacting fruit trees and such. The combination of strong return flow around departing high pressure to our east and low pressure moving up to our west through Tuesday should then lead to pronounced warming as well as low end chances for showers. Another area of low pressure moving across the region in the Wednesday to Thursday timeframe will bring better chances for showers. Temperatures remaining above normal through Wednesday night followed by a return to near normal Thursday.

AVIATION. (For the 00Z TAFS through 00Z Friday evening) Issued at 732 PM EDT Thu Apr 22 2021

VFR.

High pressure is crossing the TN/OH Valleys. As the high shifts east, winds will back, and warmer air will continue to work into the region. Our airmass is quite dry, and only patchy mid/high clouds are expected on Friday. VFR.

W to sw winds will be a touch gusty early this evening and again Friday.

MARINE. Issued at 329 PM EDT Thu Apr 22 2021

Some W/SW gustiness noted out there this afternoon particularly through the Straits with channeling/funneling. Marginal small craft conditions, but will maintain our current small craft advisory for those areas through early evening. Winds diminish overnight and Friday and we should remain marine headline free through the day Saturday. Stronger gusts return Saturday into Sunday with marine headlines likely at that juncture.
