Short term (today through Saturday night)
issued at 244 am cdt Wed aug 21 2019
ready for another round of cooler, less humid conditions as we head
into the waning days of august? A quite nice forecast shaping up as
we wrap up the work week and head into at least Saturday, as
canadian high pressure rules the roost across the region. Before
that arrives, however, still watching a slower moving frontal
boundary just drifting south into central wisconsin and southeast
minnesota as of 07z. Said front has been producing a few showers
from time to time as low level convergence works with modest
boundary layer moisture (dew points near 70) and associated cape
up to 800 j kg, with the potential for a few straggling showers
to linger up through sunrise or so as the front clears the area
by 14z. Meanwhile, we'll watch rounds of convection off to the
west and south through the day, driven by a more notable
shortwave working east out of nebraska and into southern iowa by
evening. Most of that activity should scrape by just south of the
local area, though we'll have to ultimately see just how much
"debris" clouds are present farther north with hints that areas
south of i-90 may well end up pretty cloudy with mid high clouds
rolling by into the afternoon.

Otherwise, a notable change in airmass will arrive from north to
south through the day as high pressure makes its presence felt. Said
high then looks to gradually slide across southern ontario through
Saturday night, firmly maintaining an influence on our weak with an
extended stretch of less humid and cooler, comfortable weather with
temperatures again below normal for much of the stretch. Outside of
the typical river valley fog concerns which come with the territory
this time of year (looks most likely by Thursday Friday nights with
a deep light wind layer), we'll have to watch a stronger shortwave
dropping through the region on Thursday. Not much moisture to work
with given the setup, but steeper low mid level lapse rates may be
enough to fire off a few diurnally-driven showers, particularly east
of the mississippi river. Otherwise, some great "windows open"
weather on the way - enjoy!

Long term (Sunday through Tuesday)
issued at 244 am cdt Wed aug 21 2019
a bit more summer-like into early next week as better low level
southerly flow becomes entrenched across the region, allowing
temperatures to warm back to more seasonable levels while humidity
also gradually climbs (it is still august after all). All the
while, a deeper longwave trough looks to gradually develop across
western canada down into the northern plains, with various
shortwaves ejecting eastward from that feature. Plenty of timing
and placement differences at this time range, but the overall idea
of increasing shower and storm chances by early in the work week
appears on track as a cold front approaches, though we may
initially fight entrenched dry air with eastward extent. At the
moment, consensus would favor a cold frontal passage and highest
rain chances sometime later Monday, with a return to high pressure
and less humid conditions arriving by the middle of next week.

Aviation (for the 06z tafs through 06z Wednesday night)
issued at 1048 pm cdt Tue aug 20 2019
brief MVFR conditions are possible tonight in stratocumulus. A
cold front and weak disturbance sags southeast across the area
bringing a few showers overnight. High pressure builds in on
Wednesday providingVFR conditions. Mid to high level clouds will
be found at the TAF sites at times from mid Wednesday morning into
the afternoon.

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.
