Area Forecast Discussion National Weather Service Lake Charles LA 359 PM CDT Sat Jul 3 2021 .DISCUSSION... .SHORT TERM (Today through 12Z Tuesday)... The surface frontal boundary has been continuing to make its way south into our area today and is expected to stall over our area this evening. This has led to elevated shower and thunderstorm chances throughout the day today with the interaction of moisture from the Gulf of Mexico. Showers and thunderstorms will be expected to diminish over land this evening due to weakening convergence boundaries with the loss of daytime heating as well as the stalling front reducing any forced uplift over the area. The latest run of the HRRR (18Z) shows convection forming primarily along the I-10 corridor and to the south for the remainder of this afternoon into this evening, with inland storms dissipating later in the evening. The stalling frontal boundary will continue to provide elevated precipitation chances overnight primarily for offshore areas. However, a few showers could develop near the coast as well during this time period. The pressure gradient has remained weak which means winds have been fairly light and will continue to be over the next few days. The front will remain stalled over our area and eventually dissipate by 12Z Tuesday. The lingering frontal boundary will lead to elevated precipitation chances most notably during the daytime hours on Sunday and Monday (aided by daytime heating). Flooding will continue to be a concern over the next few days due to the elevated chances for showers and thunderstorms combined with the already saturated ground. Since flow will be light, storms that develop may be slow movers and cause localized flash flooding. 55 .LONG TERM (Tuesday through Sunday)... Unfortunately, no real change to the long term period as the persistent wet pattern looks to continue. On Tuesday, we will be watching Elsa at it moves into the eastern Gulf. Although no direct impacts to the CWA are expected, some downstream effects, mainly in regards to elevated rain chances, are possible. With Elsa to our east, we will remain under a persistent upper level weakness/trof over the Southern Plains/Western Gulf. This trof in combination with a deep influx of moisture through the lower levels will result in another day of widespread showers and thunderstorms across SE TX/SW LA, especially during peak heating hours. Coverage should largely taper off with the loss of heating, however, with the favorable synoptic set up a better than normal coverage of showers and thunderstorms is likely overnight as well. Heading into the midweek, the wet pattern continues as the upper level weakness remains overhead and PWATs hover around 2 inches. So with minimal to no capping and plenty of moisture available the atmosphere will remain primed for widespread convection. Still expecting the same general pattern of highest POPs in the afternoon, tapering off overnight, both Wednesday and Thursday. By Friday, the pattern looks to break a bit as the sub-tropical ridge begins to build across the Gulf Coast. Ridging should remain overhead through the weekend, providing some relief from the extremely wet pattern we've been experiencing. That said, still carrying small POPs Fri- Sun, but coverage should be a lot more isolated. Unfortunately, with the wet pattern ending it looks like a return of highs in the low to mid-90s by the end of the period. 17 && .PRELIMINARY POINT TEMPS/POPS...
