Synopsis
Issued at 315 am edt Thu may 23 2019
- showers and a few storms Friday afternoon Friday night
- predominantly dry weather for the memorial day holiday weekend

Update
Issued at 927 am edt Thu may 23 2019
drying and subsidence moving on with all precip ended and coastal
fog mixed out. Removed pops for this morning as well as fog near
lake michigan.

Discussion (today through next Wednesday)
issued at 315 am edt Thu may 23 2019
showers and scattered thunderstorms will continue to develop early
this morning along and out ahead of the approaching sfc cold
front. Pcpn will already be exiting our area by mid morning with
decreasing cloud cover and windy conditions developing late this
morning and afternoon. Wind gusts will stay below advisory criteria
but some gusts in the 30 to 40 mph are expected as deeper mixing
occurs later today. Relatively highest gusts should occur near to
mainly east of us-131.

Winds will subside this evening with dry wx overnight through
midday Friday. Some showers and isolated storms may develop as
early as Friday afternoon due to decent isentropic upglide north
of the warm front.

The better chance for rain and also some convection will come
Friday night near and out ahead of the cold front. Severe wx is
not expected. However some gusty storms seem possible mainly late
Friday night early Saturday morning given strong low level wind
fields and an increasing 45 to 55 kt LLJ aimed at our area.

After some lingering morning showers over our southern counties
early Saturday dry wx is expected for the vast majority of our
memorial day holiday weekend. Scattered showers may develop on
memorial day but medium range guidance guidance trends suggest
that most of the rain and convection will be focused north to nw
of our area.

Tuesday looks warm and humid and an increasingly warm and unstable
airmass out ahead of the next cold front could potentially set the
stage for some stronger convection by Tuesday afternoon Tuesday
night which could linger into Wednesday.

Aviation (for the 12z tafs through 12z Friday morning)
issued at 740 am edt Thu may 23 2019
showers departing to the east early this morning then turning
quicklyVFR. Stratus and dense fog at the lakeshore is leading to
lifr at mkg but that too should mix out later this morning with
vfr following.

The main aviation issue today will be the strong west winds which
will gust over 30 kts at times. Strongest gusts inland from lake
mi where deeper mixing expected. Winds diminishing tonight and
remainingVFR.

Marine
Issued at 927 am edt Thu may 23 2019
webcams and buoy observations show that the fog has dissipated
and waves winds have decreased, so the small craft advisory has
been cancelled.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
