Area Forecast Discussion . Updated Aviation National Weather Service Saint Louis MO 551 AM CST Sat Jan 18 2020

SHORT TERM. (Through Late Sunday Afternoon) Issued at 230 AM CST Sat Jan 18 2020

Rain continues to move east thru the area this morning. The last of the rain shud be across far eastern portions of the CWA at 12z and quickly move out of the area. The Flood Watch is expected to be able to expire at 12z if not canceled early. A few showers, currently over western MO and eastern KS, may be impacting far northwestern portions of the CWA. This precip shud be rain, but some light snow will be possible.

Otherwise, a strong cold front will push thru the area today, bringing much colder air and gusty WNW winds. High temps for today shud occur by Noon with temps falling thru tonight. The falling temps and strong winds result in wind chill values approaching -15F across the northern third or so of the CWA.

Cold temps continue for Sun as a strong surface ridge builds into the area. Models are in good agreement with temps expected to remain below freezing across the region despite insolation with 925mb temps around -8C or colder.

LONG TERM. (Sunday Night through Friday) Issued at 358 AM CST Sat Jan 18 2020

Models are still in good agreement with a strong surface ridge building into the region, remaining over portions of the CWA through Wednesday. Will see continued CAA across the area thru Mon night as the ridge builds into the area. This will result in temps some 15 to 20 degrees below seasonal average, as well as another night of wind chill values in the -10 to -15F range Sun night.

A potent s/w will drop thru western portions of the area on Mon into Mon night. Model solns differ regarding amount of precip with this s/w, but with such cold temps in low levels, some light snow is looking more likely. However, with better chances west of the CWA, have kept PoPs dry for now.

Some warming shud begin Tues afternoon as southerly winds return to the area, but any warmup will be slow. Precip chances return Wed and increase Thurs into Fri. However, a fair amount of differences in model solns, have kept PoPs in chance range for now.

AVIATION. (For the 12z TAFs through 12z Sunday Morning) Issued at 549 AM CST Sat Jan 18 2020

Cold front will move through the region this morning with the winds veering to the west to northwest and picking up. Will have gusts near 30kts at times. Otherwise, IFR ceilings will persist through early this afternoon for KUIN and the STL metro area TAFs while KCOU will see ceilings lift to MVFR by 14z. Then ceilings will lift to VFR and scatter out by late this afternoon/early this evening everywhere.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
