Area Forecast Discussion National Weather Service Gaylord MI 254 PM EDT Tue Aug 11 2020

NEAR TERM. (Through Wednesday) Issued at 254 PM EDT Tue Aug 11 2020

. Warm . clear and quiet thru Wednesday .

High Impact Weather Potential . None.

Pattern Synopsis/Forecast . High pressure and dry air continue to build into the Western Great Lakes region this afternoon in the wake of a cold front that moved thru our area yesterday. A few fair wx CU tried to develop this afternoon across interior sections of Northern Lower Michigan . but quickly died thanks to strong subsidence and dry air thru the column.

The next 24 hours will feature beautiful summertime Northern Michigan wx . with clear skies . low humidity and light breezes. Low temps tonight will cool into the mid 50s to around 60 degrees. High temps Wednesday afternoon will warm into the 80s across our entire area. Enjoy!

SHORT TERM. (Wednesday night through Friday) Issued at 254 PM EDT Tue Aug 11 2020

. Above Normal Temperatures .

High Impact Weather . None is expected.

Forecast Concerns . None at the moment.

Models continue to be in excellent agreement with increased ridging aloft and high pressure at the surface. This is expected to lead to clear to partly cloudy skies and very warm temperatures. Highs in the mid and upper 80s and lows mainly in the 50s.

LONG TERM. (Friday night through Tuesday) Issued at 254 PM EDT Tue Aug 11 2020

. Very Warm then Cooler .

High Impact Weather . None is expected at this time.

Extended models are in better agreement this go around that upper level ridging holds on into Saturday night. An upper level trough moving to our north then looks to drag a surface cold front across the region Sunday into Sunday night bringing chances for showers and storms. So after more very warm temperatures, cooler air is expected to begin next week.

AVIATION. (For the 18Z TAFS through 18Z Wednesday afternoon) Issued at 100 PM EDT Tue Aug 11 2020

Strong high pressure and dry air thru the column will maintain solid VFR conditions for all Northern Lower Michigan TAF sites this afternoon thru Wednesday. W/NW winds around 10 kts this afternoon will become light/variable tonight . which will lend to lake breeze development on Wednesday.

MARINE. Issued at 254 PM EDT Tue Aug 11 2020

Winds and waves will remain below SCA criteria thru Thursday as overall high pressure remains in control of the wx across the Great Lakes region. No precip is expected until late this weekend.

APX WATCHES/WARNINGS/ADVISORIES. MI . NONE. LH . NONE. LM . NONE. LS . NONE.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
