SHORT TERM. (Through Late Wednesday Afternoon) Issued at 359 PM CST Tue Dec 10 2019

High pressure centered over eastern Nebraska will drift southeast tonight and Wednesday. Models show the high flattening out into an elongated ridge stretching from east Texas northeast into Tennessee, Kentucky, and West Virginia by early Wednesday morning. A weak short wave currently over northeast Nebraska will dig southeast into Iowa tonight and will help to develop a weak warm front across Iowa and northern Illinois. Low level warm advection and moisture convergence looks to produce a little light snow across Iowa and northern Illinois and the southern edge of the forcing does scrape far northeast Missouri and west central Illinois late tonight. Current thinking is that any accumulating snow will stay north of our forecast area . though a few flurries aren't out of the question. Lows tonight should be similar to last night's, although we might see a little bump before sunrise as the wind turns to the south with the high moving into the lower Mississippi River. With the southerly flow continuing on Wednesday highs are expected to be 5 to 10 degrees warmer than today's in the mid 30s to mid 40s.

LONG TERM. (Wednesday Night through Next Tuesday) Issued at 359 PM CST Tue Dec 10 2019

Southerly flow continues for Wednesday night through Friday. This will bring more mild temperatures back to the mid Mississippi Valley with highs in the mid 40s to low 50s and lows mainly in the low to mid 30s. Medium range models are in pretty good agreement that the next strong short wave to move through the Midwest Friday night into Saturday will push a cold front through Missouri and Illinois. Temperatures will fall sharply behind the front late Saturday and Saturday night into the teens and 20s, and current indications are that it will struggle to get above freezing on Sunday. Mid and upper level flow quickly becomes zonal after FROPA, so the front should stall somewhere across the lower Mississippi Valley on Sunday, then the next short wave digs into the Great Plains Sunday night into Monday. Guidance shows low level moisture convergence along the baroclinic zone moving across Arkansas and southern Missouri Monday morning, and the GFS pushes the moisture convergence north all the way into Iowa. The EC is more conservative, but both models do print out precip across the majority of the forecast area. GEFS plumes are almost all showing precip from late Sunday through Monday, although there is quite a spread on how much. Temperatures should be cold enough for at least part of the time it's precipitating for some kind of wintry precip, though it's very early yet so have just kept a rain/snow mix going in the forecast at this time.

AVIATION. (For the 00z TAFs through 00z Wednesday Evening) Issued at 530 PM CST Tue Dec 10 2019

VFR and dry conditions prevail across the area through the TAF period. Lower clouds at UIN will shift east and dissipate as the night goes on. Tomorrow winds will stay variable until becoming predominantly southerly in the late evening, but remain light until the end of the period.

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.
