Area Forecast Discussion National Weather Service Lake Charles LA 628 AM CDT Wed Apr 21 2021

DISCUSSION. For the 21/12Z TAF Issuance.

AVIATION. High pressure over the Northern Plains will continue to build into the forecast area today. This will provide dry conditions in the low levels with just some passing high level cloudiness. Therefore, VFR conditions are expected. North winds with gusts around 20 knots will persist until late afternoon.

PREV DISCUSSION. /issued 352 AM CDT Wed Apr 21 2021/

DISCUSSION . The frontal boundary has pushed offshore early this morning as cooler, drier air advects into the region on brisk northerly winds. Dewpoints are already back into the mid 30s across central Louisiana with temperatures falling back into the 40s. The elevated winds will persist through the day adding a bit of bite to temperatures that will already be running about 10 degrees below normal despite abundant sunshine.

High pressure will settle nearly overhead tonight allowing winds to calm and providing a nearly ideal radiational cooling environment that will allow lows to drop into the lower 40s across central Louisiana and upper 40s along and south of the I-10 corridor. As the high slides east of the region Thursday, temperatures will begin to moderate as southeasterly flow becomes reestablished.

The next weather maker will be another, less potent, cold front progged to push through the area late Friday or early Saturday. The region is expected to be warm sectored through much of Friday with a strengthening low level jet over the area providing decent shear while also pumping in plenty of moisture. This will lead to a severe weather threat especially Friday afternoon into Friday evening as the atmosphere increasingly destabilizes. SPC has the entire region (along with a large swath of east Texas) highlighted in a slight risk for severe weather during this period. In addition to the severe weather threat, the abundant moisture will also provide support for efficient rain producing thunderstorms that could lead to some localized flash flooding.

The good news is the front should push through the area at a descent clip (unlike last week's fronts) which should limit the flash flood threat. Drier air will advect into the region behind this front through the weekend, but without as much of a drop in temperatures. High pressure once again builds into the region Sunday and Monday which look very pleasant with afternoon highs in the lower 80s along with plenty of Sunshine.

Very good agreement in the long range on another front approaching the area Tuesday with the area again warm sectored ahead of it's passage indicative of another potential severe weather threat mid next week. Will have to evaluate the run to run consistency, but confidence in this solution is higher than normal for the day six and seven timeframe.
