Area Forecast Discussion National Weather Service Lake Charles LA 551 AM CST Sun Jan 19 2020

AVIATION. VFR conditions are expected through the period. Gusty north to northeast winds are expected today, but decrease in speed tonight.

PREV DISCUSSION. /issued 510 AM CST Sun Jan 19 2020/

DISCUSSION . CDFNT has pushed well SE of the forecast area early this morning, though there are still some lingering patches of light rain across coastal SC LA per latest radar imagery. This activity should ease off to the ESE over the next couple of hours or so. With the exception of this area where some low/mid clouds remain, the bulk of the area is now clear or seeing only thin cirrus.

Temperature falls thus far have been a little slower than expected, with readings still a good 10 degrees or so warmer than forecast lows. Still, robust CAA will continue to drive readings lower for another few hours even after sunrise, with the JAN sun taking some time to serve as an offset. On the other end of the spectrum, dewpoints are falling more quickly than most guidance, with readings in the upper 20s already nosing into Central LA.

Overall, forecast in the short term remains on track, with an expansive cold Canadian high progged to prevail across the ERN CONUS keeping dry weather and below normal temperatures around for the next few days. TUE morning continues to be coldest of the forecast period, with some mid to upper 20s now expected over parts of east central LA and at least a light freeze expected across most areas away from the coast.

Increasing clouds can be expected starting TUE night ahead of an upper trof approaching from the west, with warmer temperatures and increasing SFC MSTR following suit on WED as return flow becomes established. Still a fair amount of spread in global model guidance on specifics like the evolution of the trough and associated SFC features, though a shift toward an inland SFC low is apparent in latest runs. At the minimum, there continues to be enough consensus to maintain high rain chances from WED night through THU, with chances decreasing from W to E THU night into FRI leading to a dry weekend.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
