Short term (through late Friday afternoon)
issued at 352 am cst Thu jan 24 2019
main concerns with this forecast will be wind chills tonight and
snow chances tomorrow. Have expanded the wind chill advisory
tonight to include a few more counties in south central illinois.

Latest GOES imagery was showing clear skies currently over the cwa
with mid-high clouds entering western missouri and low clouds over
nebraska and northern iowa. These low clouds were behind a cold
front that will be moving quickly southward across the CWA later
this morning. Still expect scattered flurries today as forecast
soundings are showing a thin band of moisture with a minimal amount
of CAPE below 850mb. Expect the flurries and clouds to move out of
the area by this evening. It will be very blustery today as a
strong pressure gradient behind the front will cause sustained
northwest winds between 15-25 mph with gusts between 25 and 35 mph.

The highest winds today will be across northeast missouri and west
central illinois.

Tonight will be very cold with clearing skies, though expect the
winds to remain up as the surface ridge stays just to our west. Went
at or slightly below guidance temperatures as we will start out with
cold temperatures this evening and have clear skies tonight. Wind
chills values tonight into early Friday morning are still around -15
degrees over the going advisory area. Added a few more counties in
south central illinois where I also expect criteria to be met late
tonight.

Nam GFS will bring another shortwave trough across the missouri and
illinois late on Friday afternoon. There will be an attendant low
pressure system that both models are tracking southeastward from
southern iowa across northern missouri into southwest illinois.

While there will be limited moisture available, snow ratios will be
20:1 tomorrow afternoon with the quick moving storm. So have gone
with chance pops north of i-70 tomorrow afternoon, with likely pops
over northeast missouri into west central illinois. Total snowfall
at this point looks like they will be under 1".

After a cold start on Friday morning, warm air advection behind the
surface ridge will allow temperatures to climb back into the 20s,
still 10-15 degrees below normal.

Long term (Friday night through Wednesday)
issued at 352 am cst Thu jan 24 2019
very deep and amplified mean trough over the eastern half of the
country will remain in place with a series of shortwaves sliding
through the region every 24 to 36 hours. Otherwise, Friday night
through Monday, temperatures will slowly moderate with highs by
Monday in the low 30s to near 50 degrees, then another shot of much
colder air will move in.

Friday night a clipper system will be exiting the region with light
snow tapering off by 06z Saturday. Then a weaker clipper system will
slide through during the day on Saturday. However, moisture will be
very limited with it so do not expect any accumulating snows, just
some very light snow flurries.

Beyond Saturday, the models continue to have quite a number of
solutions from run to run, so will stick with super blend solution.

Next shortwave that will slide through will be late Saturday night
through Sunday morning, then less than 24 hours later another system
will begin to move through region. This system still advertised to
usher in much colder air through the middle of next week.

Aviation (for the 06z tafs through 06z Thursday night)
issued at 1115 pm cst Wed jan 23 2019
not a lot of changes from the previous tafs, but did make some
tweaks to timing of lower cigs. Clouds have cleared the region and
still anticipate low MVFR CIGS to return to the region thurs
morning. Given the cold temps within these clouds, still
anticipate flurries with the lower cigs. Expect these CIGS to
slowly lift during the afternoon and eventually becomeVFR during
the late afternoon or into the evening. Winds will become NW with
gusts in the 25 to 30 kts range. These gusts will be slow to
diminish after sunset.

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.
