632 am cdt Thu mar 21 2019

Short term
231 am cdt
through Friday...

an upper level disturbance, currently overhead, will continue to
result in some scattered light showers across the northeastern il
through around daybreak this morning before it begins to shift out
of the area. While the precipitation will be waning, expect lower
cloud cover to remain over the area through the morning, before
gradually scattering out this afternoon.

While north-northwesterly winds will start the day, expect the
winds to back more westerly this afternoon in response to the
approach of another surface trough of low pressure. These westerly
winds this afternoon will advect in a slight warmer airmass over
the area for the afternoon. This will result in surface
temperatures warming into the mid to upper 40s, especially away
from lake michigan.

Another cold front will drop southward across the area later this
evening, bringing a return to northerly flow over the area later
tonight and into Friday. This should set up a colder day over the
area on Friday, especially for areas near the lake, where a stiff
northeasterly wind will likely keep temperatures in the 30s.

Long term
254 am cdt
Friday night through Wednesday...

long term period will feature a pattern change across the country
with blocky pattern that has slowed halted the progression of
systems the past several days breaks down and we transition to a
more progressive pattern as we get deeper into next week.

First item of note is the upper low that has seemingly been
trapped beneath a high amplitude ridge over the western u.S. Will
push eastward and should bring rain to the area later Sunday into
Sunday night. It does appear likely that the precipitation will
end before switching over to snow.

A deep long wave trough is progged to dig into the northeast u.S.

And eastern canada early next week with a quite formidable push
of arctic air taking aim on new england. As guidance is depicting
it now, we should just get a glancing blow from this record
threatening cold over new england and just see some windy and
seasonably cold temperatures Monday.

The pattern looks to be fairly progressive with this trough
progged to move east by mid week as upper ridging spreads east
into the central u.S. The result will be moderating temperatures
and if trends hold, at least a couple few days of near to above
average temperatures later next week.

Aviation
For the 12z tafs...

some light showers continue across the eastern terminals early
this morning. This activity will continue for another couple hours
this morning before ending. However, expect ifr to low end MVFR
cigs to be in place for much of the morning, before improvement
occurs this afternoon. Otherwise, expect north-northwest winds to
continue across the area through early afternoon today, before
the winds back more westerly in response to the approach of
another surface trough of low pressure. This trough of low
pressure will then shift another cold front across the area later
this evening, with northerly winds likely to set up again in its
wake and persist into Friday.

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.
