Synopsis

- showers and thunderstorms tonight
- more rain Friday and Friday night
- memorial day weekend weather mostly dry

Discussion (this evening through next Wednesday)
issued at 324 pm edt Wed may 22 2019
synoptic pattern continues to feature an active storm track
through the upper midwest and great lakes between a SE conus
upper ridge and west CONUS troughing.

Dry slot currently bringing clearing skies to west michigan but
this break in the rains will be short-lived as another quick
hitting line of showers and thunderstorms will fire up late this
evening along area of elevated instability and moisture pooling
ahead of sfc cold front.

Next in the series of lows ejecting out of the plains and
tracking across the northern great lakes will bring more rain
beginning Friday afternoon and evening in area of isentropic
ascent with surface warm front pushing north then returning south
late Friday night.

Saturday and Sunday look mostly dry but steadier rains may be
returning for memorial day, as today's models have trended
stronger and faster with the next surface flow moving out of the
plains in the continuing parade that never seems to end.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
