Area Forecast Discussion...UPDATED National Weather Service Jackson MS 714 AM CDT Wed May 25 2022 ...SEVERAL ROUNDS OF HEAVY RAIN TO AFFECT THE AREA THROUGH THURSDAY MORNING... .UPDATE... Updated for 12Z aviation discussion. && .AVIATION... 12Z TAF discussion: Several rounds of showers and thunderstorms are expected to move across the forecast area through the TAF period. Periods of reduced visibility and impacts from TSRA are expected, as well as periods of MVFR or lower ceilings. /NF/ && .DISCUSSION... Today and Tonight: A low pressure system continues to rotate over the High Plains early this morning, with several shortwaves rippling out ahead of it in the upper-level flow. Generally warm and humid conditions persist across our forecast area downstream of this low pressure system, and each impulse will trigger another round of showers and storms to move through the area. Looking at MRMS estimated rainfall amounts, a fairly broad average of 0.5 to 1.0 inches of rain has fallen across our forecast area in the last 24 hours, with pockets of 2+ inches scattered about. Generally higher amounts over the last few days have been focused closer to the Gulf Coast, where model guidance suggest the best chances for additional higher amounts to be focused today into Thursday morning. Therefore, have updated our Hazardous Weather Outlook text and graphics to included an Elevated threat for flash flooding from Catahoula and Concordia Parishes in LA east through Jones County in MS. A Flood Watch has also been issued for those areas for possible flash flooding through about Noon on Thursday. With these lines of storms expected to move through with modest instability and wind shear in place, a Marginal Risk for severe storms will continue through tonight as well. Damaging wind gusts and small hail are the expected hazards with any strong to severe storms. By late tonight into early tomorrow morning, a cold front associated with a more pronounced shortwave pivoting across the Gulf Coast region will bring steadily drying air and an end to heavy rain chances for northeast LA and southeast AR by sunrise. /NF/ Thursday through next Tuesday: The period of wet weather will come to an end across the forecast area through mid-afternoon Thursday. Showers and isolated storms will exit east of the forecast area during this time. During the evening hours Thursday, the cold front itself will make its way east into and through the CWA, with high pressure building into the region in its wake. Slightly cooler drier air will filter into the region Thursday night into Friday. Fortunately, a return to quieter weather will exist Friday into early next week, thus giving the area a chance to dry out. Unfortunately, the slightly cooler drier conditions will come to an end late in the Memorial Day weekend into next week. During this time, humidity levels will again creep up, with highs climbing back into the 90s. /19/ && .PRELIMINARY POINT TEMPS/POPS...
