Synopsis
Issued at 247 pm edt Sun jun 25 2017
cool weather is expected to continue through Tuesday with lows
generally in the upper 40s to mid 50s and highs in the upper 60s
to mid 70s. There is a low chance for isolated showers and
thunderstorms Monday afternoon. Mainly dry otherwise through the
middle of the week.

Short term (this evening through Monday night)
issued at 247 pm edt Sun jun 25 2017
little change (cool mainly dry) is expected into tonight and Monday
as an upper trough remains place across the great lakes. Low level
troughing and more pronounced bouts of cva will also continue to
focus better shower chances north of the local area, though cannot
rule out a few showers into far NW in SW lower mi this evening into
the early overnight as a smaller scale moisture-starved shortwave
drops southeast from the upper midwest. Dry otherwise elsewhere
tonight into Monday morning with lows in the low mid 50s tonight.

Low chances for isolated showers and perhaps a rumble of thunder
creeps back into the forecast mid afternoon through early evening on
Monday, best chances along south of us 30 away from more stable
lake influence as the next shortwave from the upper midwest
possibly capitalizes on steepening low-mid level lapse rates weak
diurnal destabilization. Weak low level convergence and slightly
higher sfc dewpoints will also be in place here by peak heating.

However, meager moisture profiles precludes anything higher than a
20-30 pop, with small hail possible given cool profile if any
stronger cells develop. The main story otherwise on Monday will be
unseasonably cool temps with highs only reaching near 70 degrees.

Long term (Tuesday through Sunday)
issued at 247 pm edt Sun jun 25 2017
the eastward exit of the upper level trough will afford warming
temps and dry conditions into Tuesday and Wednesday. This will
likely be followed by a more active flatter west to west-southwest
flow regime Wednesday night through Friday. Increasing moisture
with strengthening south-southwest low level flow into a
developing frontal boundary will likely focus multiple
convectively enhanced shortwaves east through the midwest great
lakes during this time. The result will be periodic chances for
showers storms, with perhaps a strong severe hvy rain threat at
some point given decent wind fields and high moisture content
showing up in guidance. Chances for precipitation then diminish
next weekend as incoming height falls troughing eventually
suppresses active frontal zone off to the south.

Aviation (for the 00z tafs through 00z Monday evening)
issued at 701 pm edt Sun jun 25 2017
moisture at base of inversion aloft combined with wk lift
associated with shrtwv movg east from wi into WRN mi should cause
some alto CU to persist across NRN in through the eve. Skies
should clear again by Monday morning but CU up quickly with
diurnal heating leading toVFR ceilings much of the day. Some
potential for shra TS tomorrow aftn as a shrtwv drops SE across
srn wi mi. Best chc south of rt 30 where better low level moisture
fcst, but with strong mixing once again, model's boundary layer
moisture may be overdone. In either case, point pops too low for
inclusion in tafs attm. Rather strong gradient combined with diurnal
heating mixing should lead to west winds gusting in the 20-25kt
range once again tomorrow.

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.
