Area Forecast Discussion . Updated Aviation National Weather Service Saint Louis MO 553 PM CST Wed Jan 27 2021

SHORT TERM. (Through Late Thursday Night) Issued at 302 PM CST Wed Jan 27 2021

The back edge of a band of snow will continue to progress eastward through the remainder of the afternoon, affecting areas predominantly along and east of the Mississippi River with any additional snow accumulations less than one inch. Overnight, dry conditions will prevail along with most remaining stratus likely scattering during the first half of the night. Light winds ahead of an approaching low-level ridge and strong radiational cooling with clearing skies and fresh snow cover should allow tonight's low temps to fall into the single digits across northeastern MO and west- central IL and the 10Fs elsewhere. These conditions could also allow development of patchy fog in central MO late tonight into Thursday morning.

On Thursday, an expansive upper-level ridge is progged to shift into the central U.S. resulting in large-scale subsidence with mid-level height rises. Despite mostly clear skies, Thursday's high temps will likely only warm to around or just below average with WAA not ensuing low-level flow not turning to south-southwest until a low- level ridge shifts east of the area during the late afternoon.

LONG TERM. (Friday through Next Wednesday) Issued at 302 PM CST Wed Jan 27 2021

The upper-level ridge will continue to dominate the central U.S. into Friday with mostly clear skies and dry conditions persisting. WAA will be maintained by strengthening south-southwesterly low- level flow, allowing temps to moderate to slightly above average. However, increasing upper-level clouds and surface winds becoming slightly backed (< 180 degrees) should preclude more significant warming during Friday.

Saturday into Sunday, global model guidance continue to depict a upper-level trough with increasingly negative tilt pivoting across the Central Plains into the Midwest. This upper-level trough will lead to genesis of a surface low and attendant cold front across the Central Plains that is expected to track across the forecast area. Strong lift at the leading edge of the trough and near the surface low and cold front is expected to combine with a northward plume of moisture from the Gulf of Mexico to produce widespread precip during the Saturday-Sunday period. All GEFS and EPS members portray measurable precip for nearly the entire forecast area and support categorical PoPs Saturday into Saturday night. Forecast soundings suggest that most precip should fall as rain; however, a brief wintry mix is possible at precip onset. In the wake of the surface low and cold front on Sunday, low-level flow is expected to veer to the north-northwest and usher colder air into the region through the day. This colder air could transition lingering rain to snow showers/flurries, especially across northeastern MO and west-central IL, upper-level flow becomes northwesterly is potentially navigated by a few low-amplitude upper-level troughs.

Global model guidance are in agreement that northwesterly upper- level flow could continue into the middle of next week as an upper- level ridge shifts into the central U.S. This evolution should provide a return to dry conditions across the area along with northerly low-level flow keeping temps near average. Another upper- level trough may approach the Midwest around the middle of the week, but considerable variability among model guidance exists at this juncture.

AVIATION. (For the 00z TAFs through 00z Thursday Evening) Issued at 535 PM CST Wed Jan 27 2021

A surface ridge extending from MN south-southwest into northeastern OK will move eastward through the taf sites late tonight and Thursday morning. The north-northwest wind will become light late tonight, then southeasterly Thursday afternoon as the surface ridge axis shifts east of the taf sites. The sky will clear from the north this evening with the COU and St Louis metro area taf sites clearing out like they have already in UIN.

SPECIFICS FOR KSTL: A surface ridge extending from MN south-southwest into northeastern OK will move eastward through STL late tonight and Thursday morning. The north-northwest wind will become light late tonight, then southeasterly by Thursday evening as the surface ridge axis shifts east of STL. The sky will clear from the north this evening with STL scattering out around 03Z this evening.

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.
