Area Forecast Discussion National Weather Service Lake Charles LA 414 AM CST Tue Dec 10 2019

DISCUSSION. As of this writing, a strong cold front bisects the region roughly from near Alexandria southwest to DeRidder to just north of Beaumont. Latest radar imagery showing a broken line of heavy rain producing showers has developed along the leading edge of the boundary with more scattered showers both ahead and behind the line. Temperatures immediately behind the front are running 10 and 15 degrees cooler. Winds within the warm, juicy airmass being displaced have been light enough to allow for areas of fog development early this morning with visibilities ranging from 1/2 mile to 5 miles. Visibilities will continue to improve from west to east this morning in the immediate wake of the frontal passage.

Today's forecast can be succinctly summed up in a word . miserable. Guidance remains in nearly universal agreement on overrunning stratiform rain continuing through much of the day while strong CAA ushers in more seasonal temperatures at 20 to 30 MPH. The forecast wind speeds are on the cusp of wind advisory criteria, but with the frequent gusts to 30 MPH expected, felt comfortable issuing a wind advisory along and south of I-10. These strong winds are expected to continue into the coastal waters later this morning where gale warnings have already been issued.

Precipitation will gradually come to an end from west to east late this afternoon into this evening with winds slowly abating overnight. Clear, dry and cool conditions expected Wednesday and much of the day Thursday. Global models are depicting a surface low in the northeastern gulf Thursday better than this time yesterday which may result in some isolated shower activity across the coastal waters and lower acadiana late Thursday into lower Friday. However, the vast majority of the moisture associated with this feature is progged to be well to the east.

Southerly flow becomes reestablished once again Friday into the weekend allowing for temperatures to moderate and moisture to increase ahead of the next frontal boundary progged to approach the region Monday.

MARINE. A light to modest onshore flow will prevail early this morning with a strong cold front pushing through the coastal waters during the mid to late morning. Patchy fog will be possible ahead of the front which will dissipate as the front passes through. Widespread showers will accompany the front and will continue through much of the day. Strong north winds and building seas are expected in the wake of the frontal passage. Winds and seas will subside Wednesday night into Thursday. Onshore flow becomes reestablished late Friday through the weekend ahead of the next cold front early next week.

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