SHORT TERM. (Through Late Saturday Afternoon) Issued at 210 PM CST Fri Jan 22 2021

Surface ridge centered over IA will move east-southeastward into the Ohio Valley region by Saturday afternoon. Colder low temperatures are expected tonight with just some high level cloudiness, relatively weak winds, and very low surface dew points. Lows tonight will be about 5 to 10 degrees below normal for late January. Will only see slightly warmer high temperatures on Saturday for most of the forecast area with increasing mid-high level cloudiness.

LONG TERM. (Saturday Night through Next Friday) Issued at 210 PM CST Fri Jan 22 2021

Increasing low level temperature advection and moisture convergence on the nose of a southwesterly low level jet will result in light wintry precipitation from late Saturday evening into Sunday morning. The initially very dry boundary layer will lead to evaporative cooling and wet bulbing of the surface temperatures with the onset of precipitation. Precipitation type should began as light snow/sleet across much of the area, but transition to light freezing rain across northeast MO and west central into southwest IL late Saturday night and light rain further south-southwest in parts of central and southeast MO. Some areas will see a light dusting of snow/sleet accumulation along with a light glazing of ice accumulation. The better QPF will likely occur late Saturday night into early Sunday morning across southeast MO into southwest IL and will mainly be in the form of liquid rain. As temperatures gradually warm Sunday morning the precipitation type will change from freezing rain to liquid rain from south-southwest to north-northeast with just liquid rain across the entire forecast area by noon Sunday, although by this time it will likely be just sprinkles as most of the precipitation by this time shifts east-southeast of the region. Another round of more significant precipitation will begin by late Sunday night as upper level divergence increases over the region ahead of an approaching upper level trough moving into the Central Plains. Precipitation will spread into southern MO first then shift northward into the rest of the forecast area as Gulf moisture is drawn northward ahead of a surface low which will move into eastern OK by 12Z Monday. The precipitable water values will be anomalously high for this time of the year across southeast MO and southwest IL by 12Z Monday. Temperatures will be warm enough that the precipitation type will be mainly liquid rain, except freezing rain across parts of northeast MO and west central IL late Sunday night into early Monday morning. The surface low will move east-northeastward across southern MO and into southern IL by early Monday evening. The 850 mb low will move through central MO on Monday with the precipitation type changing over to snow across northeast MO and west central IL left of the track of the low with about 2 to 4 inches of snow accumulation possible Monday afternoon and evening. The precipitation will shift east of our area late Monday night with just a few lingering flurries. There will be a break in the precipitation threat on Tuesday with another round of precipitation possible Wednesday and Wednesday evening as a deep but progressive upper level trough moves eastward through the region. The temperatures should be a little colder with this system resulting in a potential for wintry precipitation for much of our area. A drier period of weather is expected to begin on Thursday with the models consistently depicting both ridging at the surface and in the upper levels of the atmosphere.

AVIATION. (For the 00z TAFs through 00z Saturday Evening) Issued at 519 PM CST Fri Jan 22 2021

High pressure will remain in control through the forecast period, keeping things quiet over the terminals. Intermittent high clouds will stream into the region as the surface high slides east through tomorrow. Light winds will continue to veer to the northeast and eventually southeast by tomorrow , becoming a bit stronger in the afternoon. More widespread mid/high clouds will build into the region tomorrow afternoon and evening ahead of the next chance of precipitation that will arrive late Saturday night or Sunday morning.

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.
