Synopsis
Mostly cloudy skies are expected tonight along with the possibility
of a few flurries. High pressure will build into the tennessee
valley Wednesday into Thursday, leading to dry conditions and a
gradual warming trend.

Near term until 6 am Wednesday morning
Based on the latest rh forecasts, expect the clouds currently
over the region to begin to break after midnight, leaving
scattered conditions. With light winds, this will allow
temperatures to drop quickly. So adjusted temperatures down to
-5 to +5 over the region.

Wind chills values will drop to -10 to -15 in some locations,
but winds will be light, generally less than 5 mph, so will
continue with an sps, instead of going with a advisory.

Short term 6 am Wednesday morning through Wednesday night
Surface high pressure will begin to build east into the
tennessee valley Wednesday into Wednesday night. This will allow
for the low level flow across our area to slowly back to the
northwest and then the west. This will allow for some lingering
low level clouds across the area Wednesday morning to gradually
scatter out from the west later Wednesday afternoon with mainly
clear skies then expected for Wednesday night. Highs on
Wednesday will be in the upper teens to lower 20s. Despite the
clear skies Wednesday night, a tightening pressure gradient
should help keep the winds up somewhat. This should again keep
temperatures from dropping way off and will go with lows down
around 10 degrees or so.

Long term Thursday through Tuesday
Large area of surface high pressure to slide east across the region
through the end of the week. This feature will provide dry weather
and moderating temperatures. Temperatures by the end of the week
will warm up closer to normal. Expect highs on Friday to range from
the lower middle 30s north to near 40 south.

A southerly low level flow will develop Saturday on the backside of
retreating surface high pressure. In WAA pattern a chance of a few
showers will exist Saturday. Temperatures expected to warm around 10
degrees above normal with highs Saturday from the lower 40s north to
the upper 40s south.

Mid upper level flow to back with S W and deepening surface wave
ejecting from the central plains Sunday into the great lakes Monday.

In the warm sector on Sunday the best chance of rain shifts north of
iln S fa. Therefore, will limit pops to very low chance category.

Expect temperatures to be 10 to 15 degrees above normal with highs
Sunday generally between 50 and 55 degrees.

As surface wave tracks through the great lakes associated surface
cold front to sweep east through iln S fa Monday. Therefore, will
continue high pops for rain. Above normal temperatures to continue
with highs of 45-50 Monday. In the wake of this front surface high
pressure to build in providing dry weather Tuesday. Temperatures
will continue a little above normal with highs from near 40 north to
the upper 40s south.

Aviation 02z Wednesday through Sunday
Area of MVFR clouds has settled down over the tafs. Interesting
thing about this area of clouds is that it not attached to the
lakes, and therefore it could be transient. Actually numerous
models are indicating this, by breaking up the clouds around
06z.

Clouds will remain scattered through 12z, when a band of clouds
off lake michigan will work back in. Expect the ceilings to be
MVFR with this new band. MVFR ceilings will remain through
about 18z when the back edge of band will move east leaving a
few high clouds.

Outlook... MVFR ceilings possible Saturday and Sunday.

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.
