Area Forecast Discussion . Updated Aviation National Weather Service Saint Louis MO 1128 PM CST Fri Dec 6 2019

SHORT TERM. (Through Late Saturday Night) Issued at 333 PM CST Fri Dec 6 2019

The low post frontal stratus is forecast to move south of the area by early evening, leaving a mostly clear sky for the remainder of the night. The surface high, currently centered over the Upper Midwest, will slide ESE into the area tonight into Saturday. Southerly winds on the west side of the high will advect warm air into the CWA Saturday afternoon, helping boost temperatures into the upper 40s and low 50s. Under the influence of the surface high the area is forecast to be dry until the next system approaches late Sunday night into Monday.

MRM

LONG TERM. (Sunday through Next Friday) Issued at 333 PM CST Fri Dec 6 2019

Southerly flow will persist into Sunday, causing temperatures to continue to moderate into the mid to upper 50s ahead of another surface cold front and associated low pressure system.

The approaching surface low and attendant cold front are driven by a strong mid level trough, swinging through the Midwest on Monday. Ensemble guidance and deterministic model output continue to show a signal of rain late Sunday into early Monday ahead of the front. But the main area of rain will be along the line of low level frontogenesis just ahead of the cold front. The cold front and rain will marching through during the day and exit the CWA Monday afternoon/early evening. As temperatures cool behind the front, any lingering precipitation could fall as light snow before moving out of the area completely.

Guidance is in agreement that temperatures will likely be 10 to 15 degrees below normal Tuesday through Thursday in the wake of the front, aided by a strong high pressure and associated northwesterly flow. Temperatures will rebound Friday as the high moves out of the region and flow becomes southerly once more.

Dry weather is favored behind the cold front on Monday. However, guidance is suggesting a clipper swinging through the area mid week, though deterministic guidance and ensemble members currently show little agreement in location and timing.

MRM

AVIATION. (For the 06z TAFs through 06z Saturday Night) Issued at 1114 PM CST Fri Dec 6 2019

High pressure building from the north has calmed winds at the terminals, which has increased the potential for fog at some sites. If fog develops, VSBYs should improve by the mid- morning. VFR conditions will prevail at all terminals for the remainder of the period. Winds will become predominantly southerly by the early afternoon, but remain light.

SPECIFICS FOR KSTL/KSUS/KCPS:

Calm winds at STL, SUS, and CPS, coupled with sufficiently high dew points, have increased the chance for fog at these sites. SUS should fall to MVFR VSBYs first, followed by STL and CPS. By 14Z, winds should begin to mix the fog out of the terminals. VFR conditions will then prevail for the remainder of the period.

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.
