Short term (today through Tuesday)

surface ridge in place this morning making for classic, seasonal
valley fog setup. Not sure how extensive it will get in larger
channels, but tributaries show pretty good coverage on goes-16 10.3-
3.9 um channel difference imagery. This will burn off mid morning to
setup a quiet, beautiful late summer day.
While bulk of area will remain quiet again tonight, approaching
shortwave trough from western states will likely kick off some sort
of convective system to the west overnight, with a southeast
trajectory expected. Strengthening low level jet, higher CAPE pool,
and moisture transport certainly highest to the west and southwest
of the area before shifting off to the east. Northeast iowa has
highest chance of getting clipped by this activity after midnight,
but lots of differences in short term and mesoscale model solutions.
Appears bulk of any severe weather risk would remain just southwest
of the area, in agreement with storm prediction center SPC day 1
This convective system will likely move off Tuesday morning allowing
for clearing, warm air advection, and push of higher dew points
northward ahead of stronger shortwave trough crossing southern
canada. Airmass over much of the area could become capped as
temperatures soar, but some concern there could be enough lift ahead
of this wave to break that, especially if upper levels begin to cool
closer to trough.
Bottom line is conditional convective setup will need to be watched
later Tuesday north of interstate 90. Steep lapse rates could help
fuel any convection that does form, and with better shear to work
with, a few hail storms are possible mainly northern half of
wisconsin. Some discussion with SPC about this so they will monitor
for possible upgrade to a marginal risk day 2. Again, seems very|
conditional so confidence is relatively low.
Long term (Tuesday night through Sunday)

period will largely be dominated by cooler, drier northwest flow as
upper troughing continues over eastern canada. Temperatures will
drop below normal for a few days with some cool nights expected,
especially in normal bog areas.
Medium range guidance is trending less amplified than earlier runs
and hence, tends to bring in more zonal flow and associated
shortwave troughs going into the weekend. These days littered with
small rain threats with details yet to be worked out. Could
certainly see some convective activity over the weekend, but gulf
far from open. Confidence in any severe threat that far out remains

after any early morning fog burns off at klse,VFR conditions are
likely into tonight with light winds and mostly clear skies under
weak high pressure. With very light wind flow tonight, lifr fog
may develop once again in river valleys, possibly impacting klse.
A thunderstorm complex is forecast to track mainly south west of
the area overnight, but could possibly bring some higher cloud
cover into the area. Given somewhat low confidence on potential
impacts to cloud cover, will not include any fog at klse just yet.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
