Synopsis
Issued at 310 am edt Wed may 22 2019
- showers and isolated storms early to mid this morning
- showers and thunderstorms Friday night
- memorial day weekend will be mostly dry with seasonable temps

Discussion (today through next Tuesday)
issued at 310 am edt Wed may 22 2019
a strong LLJ on the order of 45-50 kts will result in strong
moisture advection into our area early this morning. Rgnl radar
trends corroborated with a consensus of latest high res sim z
guidance suggest rain will gradually develop from wsw to ene
across most of our fcst area during the early to mid morning
hours. Elevated instability may just be sufficient enough for an
isolated thunderstorm. However this band of pcpn will gradually
weaken as it moves further ene toward mid morning and encounters
drier low level air with continued low level east winds.

A warm front will lift northward this afternoon and tonight and
cause a significantly warmer and more humid airmass to briefly
advect in on strong southerly winds. Then the approaching cold
front will result in development of showers and some thunderstorms
late tonight. It will be breezy after FROPA for Thursday with
decreasing cloud cover and much less humid conditions.

Some light rain showers may develop as early as Friday afternoon
in an area of isentropic upglide north of the warm front over the
lower great lakes region by then. The better chance for rain and
also some convection will come Friday night along and ahead of the
cold front. Severe wx seems unlikely given unfavorable frontal
timing but some gusty storms seem possible given strong low level
wind fields and a 45 to 50 kt llj.

Some pcpn may linger into Saturday morning over our southern fcst
area. After that most of the memorial day holiday weekend looks
dry for our area as the focus for showers and storms will shift a
little further south across il in oh in closer proximity to the
frontal boundary. Temps for the holiday weekend will average near
to slightly below normal for this time of year with the relatively
coolest air expected to arrive by memorial day and lingering for
most of next week.

Aviation (for the 12z tafs through 12z Thursday morning)
issued at 753 am edt Wed may 22 2019
a band of rain will continue to work through the TAF sites this
morning, moving off to the north and east by midday. Some MVFR
conditions will be possible this morning as the heavier rain moves
through. Some brief ceilings to around 2500ft are possible as are
visibilities to around 3 miles. Ceilings will rapidly improve this
afternoon withVFR conditions expected at all TAF sites.

Vfr conditions will continue this evening, with a band of showers
and thunderstorms moving in from the northwest tonight. These
showers and storms will move through the TAF sites between 09z and
12z.

Winds will be gusty this morning with the showers moving through,
but tend to settle into the 10-20 knot range this afternoon.

Marine
Issued at 310 am edt Wed may 22 2019
east to southeast offshore winds today will result in wave heights
less than four feet. Winds will veer to the south and stay up at
around 15 to 25 kts tonight before veering to the west Thursday.

Although wave heights should stay below SCA criteria we will hoist
a small craft advisory for today through tonight for 20-25 kt
winds at times.

Grr watches warnings advisories
Mi... None.

Lm... Small craft advisory until 8 am edt Thursday for lmz844>849.

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.
