Area Forecast Discussion National Weather Service Lake Charles LA 353 PM CST Sun Dec 8 2019

DISCUSSION. Mild to warm and mostly sunny afternoon across the area, with low level southerly flow now well established between eastward departing high pressure and a low pressure trough to the west over the Plains. Aloft, westerly flow prevails across the region downstream of an approaching WRN CONUS trof.

Few big changes of note made to the forecast this afternoon. Warm air advection regime already established progged to intensify tonight into MON, yielding warmer overnight/afternoon temperatures and an increasing influx of Gulf MSTR. Some guidance pointing toward fog tonight, but believe boundary layer winds will be elevated enough to inhibit any significant VSBY reductions. Temperatures tonight will be around 10-15F above seasonal normals. Mostly cloudy and warm on Monday, with highs reaching the upper 70s to near 80.

Areas of light rain/isolated showers are possible by the afternoon and evening amid increasing lift, with widespread showers and isolated thunderstorms expected after midnight as the front begins to push through the area. Rains will continue through the day on TUE with the upper trof axis still out west and isentropic ascent continuing atop the shallow cold-air wedge. Bulk of rains end W-E TUE night with the passage of the upper trof axis and punch of drier air, though at least small chances will linger into WED morning, especially SE half or so of the area.

Much colder air will intrude in the wake of the front as it passes through on TUE, with lows TUE night expected mostly in the mid/upper 30s away from the coast. Highs WED will reach only the mid 50s.

This cold airmass will be slow to modify, with only slow and steady warming each day through the end of the week. Still some spread global models regarding a second upper trof digging into the NW Gulf Coast region on FRI, though the trend favors a drier solution shown by the ECMWF and CMC. Carried very small PoPs over eastern areas THU night into FRI, similar to the previous forecast. Warming trend continues and accelerates through the weekend with southerly winds returning.

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.
