217 FXUS64 KSHV 251558 AFDSHV Area Forecast Discussion National Weather Service Shreveport LA 1058 AM CDT Wed Sep 25 2024 ...New UPDATE... .UPDATE... Issued at 1052 AM CDT Wed Sep 25 2024 Clearing skies across the heart of the ArkLaTex have allowed temperatures to rapidly warm anywhere from 3-7 degrees in the past hour. A broken to scattered cloud deck building between the I-30 and I-20 corridors should help to limit runaway heating as it slides south and east, thus based on this trajectory, nudged afternoon highs up a bit, but only by a degree or two for most area locations. Isolated to scattered additional convection is possible this afternoon along and south of I-20, likely confined largely to zone south of US-84, which is adequately reflected in the existing wx grids. Otherwise, ingested the latest several hours worth of temperature and dew point observations and interpolated through to 00Z. /26/ && .SHORT TERM... (Wednesday through Thursday) Issued at 206 AM CDT Wed Sep 25 2024 Showers and thunderstorms will continue to work into the region today, as longwave troughing and our second cold front continue to work south. This trough is very progressive in nature, with rain chances beginning to diminish by the afternoon hours. Once this cold front finally clears the region, expect the rest of the short-term to be very pleasant. Dry conditions should remain into the weekend, with afternoon highs dropping to a much more seasonable feel. The same can be said for overnight lows, with lows dropping into the upper-50s to low-60s. /44/ && .LONG TERM... (Thursday Night through Wednesday) Issued at 206 AM CDT Wed Sep 25 2024 Rain chances will return to the forecast by late Friday morning, as moisture from now Tropical Storm Helene begins to wrap around the closed low over the midwest. In turn, the best chances for organized rain will be along and north of I-20, with dry conditions south. However, as the low pressure continues to meander NE into the weekend, then the rain chances will shift NE as well. By Sunday, dry conditions will return area-wide, with limited rain chances anticipated for the rest of the long-term. High temperatures will begin to climb by Sunday as well, with highs returning to the mid to upper-80s. However, overnight lows will continue to be quite pleasant, as dry air keeps working into the region under north flow. Overnight lows will likely continue to range in the mid-50s to mid- 60s. /44/ && .AVIATION... (12Z TAFS) Issued at 623 AM CDT Wed Sep 25 2024 For the 25/12z TAF update...Radar imagery is showing fairly widespread showers and thunderstorms moving through much of the area, impacting in some way all of our terminals this morning. As a result -RA, VCTS and lower ceilings currently prevail for most of our terminals and will continue through the rest of the morning hours before some improvement is seen by this afternoon/evening. Winds have been gusty at times with thunderstorms moving through, but it has been short lived for the most part. Showers and thunderstorms should come to an end across the region by the end of the period. /33/ && .PRELIMINARY POINT TEMPS/POPS...
