Short term
1220 pm cdt
through Sunday...

dry and cooler conditions will continue through Saturday, and
generally for the weekend, though with plentiful sunshine.

Inland clouds, with enhanced convergence in southern wisconsin and
northern illinois and low coverage elsewhere, will shift inland
and dissipate later this afternoon and evening.

Otherwise, large surface high pressure over the upper great lakes
will slowly slide east this weekend, to be centered over new england
by Sunday morning. Conditions across the local area will be
unseasonably cool and dry, with highs on Saturday in the middle to
upper 70s and upper 70s to lower 80s for Sunday. Given the
continental-polar origin of the associated air mass, dewpoints will
also be relatively low, mainly in the middle 50s. Overall, this is
expected to result in pleasant weather with ample sunshine across
the area. As the high shifts and winds turn more solidly
southeast, the focus of higher waves will shift to the northeast
illinois shoreline.

Long term
205 pm cdt
Sunday through Friday...

surface high pressure is expected to shift over new england on
Sunday ahead of a developing storm system over the plains.

Pleasant weather is expected to continue Sunday, with highs into
the upper 70s to around 80across the area. However, cloud cover
will increase across the area Sunday night into Monday as moisture
increases across the area in association with the approach of a
disturbance shifting eastward across the lower missouri valley.

This system could result in some light rain potential entering far
southern portions of the area as early as later Sunday night.

On Monday a well defined mid upper level trough is forecast to
dig in over the upper midwest. As it does so, an associated
surface low will deepen late Monday and Monday night over western
ontario. This will will then drive a cold front eastward across
our area Monday night into early Tuesday morning. While there will
be some chances for showers and thunderstorms during the day on
Monday, the best chance for showers and thunderstorms looks to be
Monday night into very early Tuesday morning as the cold front
shifts across the area. Severe thunderstorms do not appear to be a
big issue with these storms, but some locally heavy rainfall will
be possible.

Any lingering showers should end quickly early Tuesday morning
following the passage of this cold front. Dry and pleasant
conditions should return to the area for midweek as a surface high
settles over the lower missouri valley. High temperatures are
likely to remain in the 70s through late week.

Overall, mainly dry conditions are expected mid to late week.

However, forecast guidance suggests that another cold front could
move over the area sometime later in the week, and this could
result in a period of showers and storms. Since this is a week
away, and timing is likely to chance, I have not strayed from the
blended guidance during this period.

Aviation
For the 18z tafs...

northeast winds in excess of 10+ kt will continue through 01-02z.

Area vwps support occasional gusts up to 20 kt. ExpectVFR clouds to
stream off the lake, with possible broken conditions north of the
chicago terminals and toward krfd. High pressure gradually building
into the upper great lakes will continue to result in some form of
east winds through the period. There will be fluctuation in wind
direction between mainly 030 and 060 degrees at chicago airports
today. Winds will gradually ease in the 00z- 03z time similar to
last evening.

Winds will veer to be more southeasterly to start the day Saturday,
but then shift back to an east-northeast with some aid off the
lake in the afternoon. Speeds again will be back above 10 kt.

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.
