AREA FORECAST DISCUSSION National Weather Service Kansas City/Pleasant Hill MO 336 AM CST Sun Dec 15 2019
Discussion. Issued at 329 AM CST SUN DEC 15 2019
A winter storm will impact the region over a two day period in two rounds, the first of which will occur this morning through the afternoon, the second of which will arrive Monday morning through the afternoon/evening time frame. Have increased forecast snowfall accumulations up to the 5 to 7 inch range, generally along an axis from the Missouri River to Highway 50, including the Kansas City area. Overall ice accumulations should be limited to around a tenth of an inch or less, mainly focused south of I-70. Have issued a Winter Storm Warning for areas along the Missouri River and points south, beginning this morning until Monday evening for accumulating snowfall up to 7 inches, with locally higher amounts possible. A Winter Weather Advisory is in effect for areas across northeast Kansas and northern Missouri, for accumulating snowfall in the 2 to 4 inch range through Monday.
The mid to upper-level storm system moved inland Saturday evening and is now working closer to the Four Corners as of early Sunday morning. Areas of light precipitation are noted on radar imagery within an area of broad and weak ascent ahead of the deepening upper-level trough axis. Cloud bases remain high as of early Sunday morning, thus not anticipating much precip reaching the surface initially, though this mid-level activity will help to saturate and prime the column before shortwave energy begins to work its way into the area this afternoon. For this morning, will see increasing precip chances by the mid to late morning across the area. With the cold air mass already in place, road temps are currently in the 28 to 30 degree range and untreated and elevated surfaces will quickly become slick once snowfall commences. Expecting to see up to an inch across most of the area before noon, while the peak window for activity today will be from noon to 6 pm. At that time, seeing signals for strong forcing in the mid-levels and perhaps a convective element, to support high snow rates along an axis extending from eastern Kansas through eastern Missouri. The exact location of where this band of potential heavy snowfall sets up is of course prone to shifting, though currently thinking areas south of the Missouri River and north of Highway 50 may see afternoon snowfall totals in the 3 to 4 inch range. Roadways will quickly become hazardous if untreated, and high snow rates will lead to reductions in visibility during peak weekend travel periods. This evening, the loss of cloud ice will cause snow to transition to freezing rain/freezing drizzle for areas mainly south of Highway 36, though overall precip chances will begin to wane overnight. The main threat at this point will be with accumulating ice up to a tenth of an inch for areas south of I-70.
The second round of wintry precip will arrive Monday morning as the main mid to upper-level trough moves into the Central Plains. This round appears to be less intense than what models previously suggested, though additional mid-level forcing for widespread precip will add to existing complications from Sunday. Precip will transition back to snow as moisture availability deepens and cloud ice returns. The peak window of activity Monday will be from the mid- morning through the mid-afternoon hours, possibly affecting both the morning and evening commutes. Snow rates should not be as high as compared to Sunday, though by this point accumulating snowfall will begin to approach the 5 to 7 inch mark, with some areas possibly seeing higher amounts where snow banding develops. The other consideration in all of this is that temperatures will remain below freezing throughout the event. Thus, travelers who may become stranded could be exposed to wind chills near 20 degrees both Sunday and Monday afternoons.
Precip will finally come to an end Monday evening, with dry conditions returning for the remainder of the work week. Temperature trends will slowly rebound beginning Tuesday and will continue the upward climb through the weekend.

VFR conditions will quickly deteriorate as a winter storm approaches the region this morning. Light snow will start over the area around sunrise, but visibility and ceilings should stay VFR until the higher snow rates move into the area in the late morning. These higher snow rates will result in IFR to LIFR visibilities and IFR ceilings. The heaviest snowfall rates and lowest visibility will move into the area in the 16-22Z timeframe with 1/2SM visibility possible at times. The snow will start to tapper off around 23-00Z which will improve visibility, but ceilings look to stay around IFR, except for up near KSTJ where they may lift to MVFR. Freezing drizzle still looks to be a potential issue from 00-04Z, but should be contained to areas along and south of the Missouri River with KMCI being just north of that threat.

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.
