. AVIATION UPDATE .
UPDATE. Issued at 843 PM CST Sun Dec 15 2019
Heavier snow band setup a little further north than expected. As a result, had to move the advisory north to Des Moines, Henderson and Warren Counties. This heavy band should move out of the area by 11pm. After this, light snow is expected. Still seeing area roads covered with snow, this will cause slick conditions for the am commute, especially on untreated roadway surfaces.
SYNOPSIS. Issued at 309 PM CST Sun Dec 15 2019
Area radars and surface reports showed a large area of snow from KS, SE NE across MO into southern IL this afternoon. This was in an area of lift ahead of a low amplitude trough lifting out of the Rockies and an associated 850 mb low. The northern edge of this snow with enhanced bands, had overspread northeast Missouri and southeast Iowa early this afternoon. Elsewhere, conditions were seasonably cold and dry under thickening high level cloud cover.
SHORT TERM. (Tonight) ISSUED AT 309 PM CST Sun Dec 15 2019
A Winter Weather Advisory has been issued for northeast Missouri, adjacent west central Illinois and Lee county in southeast Iowa for late this afternoon through tonight. Expected snow totals of 1 to 3 inches this evening may be followed by patchy freezing drizzle, leading to slick roads. This will join the Winter Weather Advisories already in place over northern Missouri and adjacent areas of central Illinois. However, those headlines continue into Monday to cover a secondary round of snow that is not expected to impact our forecast area.
The 12z operational NAM and GFS, show an FGEN band advancing into northeast Missouri into southeast Iowa late this afternoon and early evening with overall weakening trend. Latest hi-res models also have this signal. There is some question as to whether this will in the current area setting up from Van Buren into Des Moines counties or further south. Locations under this will see periods of moderate snow, otherwise, it looks like roughly 4 to 6 hours of light snow with totals in the 1 to 3 inch range before the upper level forcing rapidly exits eastward after midnight. After midnight, model soundings sections become less favorable for any ice introduction for snow and more favorable for drizzle. With temperatures holding in the teens and 20s through the night, this would lead to at least patchy freezing drizzle, especially across the far south. Confidence that this will be significant is low but will mention in the advisory product.
North of the advisory, the forecast maintains snow totals of .5 to 1 inch from the highway 34 corridor up to I-80, then mainly trace amounts further north. This will overspread the area from SW to NE, as currently underway. Winds will be very light ahead of in-building surface high pressure, so there will be no risk for blowing or drifting.
LONG TERM. (Monday through Sunday) ISSUED AT 309 PM CST Sun Dec 15 2019
Monday: Maybe some flurries in our far south in the morning then a chance of light snow in the afternoon. This second round occurs as low pressure begins to develop in the Lower MS Valley. The GFS suggests the far southern cwa will be on the northern fringe of the main pcpn area. However, the ECMWF is farther south and keeps the dvn cwa dry. This is the reason for keeping only a small chance in our far south as there is low confidence in this scenario. The remainder of the cwa will be influenced by dry arctic air. Highs will be in the upper 20s.
Monday night through next weekend: This looks to be an extended period of quiet and dry weather as the area will be mostly dominated by a northwest flow aloft. The storm track will be well to our north and east. There is a secondary cold front arriving about Tuesday but this will be moisture starved and the forcing is in the Great Lakes region. Otherwise, temperatures should moderate later in the week and through the weekend with highs in the 40s and lows in the 20s.
AVIATION. (For the 06Z TAFS through 06Z Monday Night) ISSUED AT 1122 PM CST Sun Dec 15 2019
Areas of light snow will diminish early in this period with visibilities expected to improve to 6SM or better. MVFR stratus clouds will persist through part of tonight at KCID and KDBQ, and into Monday morning at KMLI and KBRL.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
