This bulk download tool provides the NWS text
in a raw form, hopefully directly usable by your processing system.
You can either provide a complete 6-character PIL/AFOS ID or provide
the 3-character base ID (e.g., AFD
). The start and end
dates represent 00 UTC for those dates. The Zip format is useful as
the filenames will have the product timestamp, which is useful for
when the product format has ambiguous timestamps.
221 FXUS64 KLIX 202351 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 651 PM CDT Sat Jul 20 2024 ...New AVIATION... .SHORT TERM... (This evening through Sunday night) Issued at 215 PM CDT Sat Jul 20 2024 Due to some drier air filtering in from the north, the area is seeing only some isolated showers and storms with it clustered east of I-55 and along/south of the I-10/I-12 corridor. However, for this area, we have already had repeated rounds of rain the past couple of days and the current line looks to be training a bit, so where is some concern of isolated flash flooding. Otherwise, there really has not been much change in the pattern so it continues to be day to day diurnally driven hit and miss showers and storms. Temperatures will remain in the upper 80s to low 90s if showers and thunderstorms don't impact an area. However if it does it may be into the 70s and low 80s instead, but due to the isolated nature of the rain today left it overall unchanged. && .LONG TERM... (Monday through Friday night) Issued at 215 PM CDT Sat Jul 20 2024 Not sure what to say other than it's more of the same. We continue to have the same summer pattern showers and storms through most of the next week. Since the showers and storms continue for the mostly foreseeable future, still keeping an eye on flash flooding potential. PoP chances go down slightly and max temps go up as we approach mid to late next week as the upper level ridge mostly dominating over the western CONUS will drift eastward. We'll still have daily chances of storms but not as much as we've seen a few days ago. But without the more widespread rain chances, high temperatures will likely start creeping towards heat advisory criteria again especially late next week. && .AVIATION... (00Z TAFS) Issued at 645 PM CDT Sat Jul 20 2024 While terminals were VFR at forecast issuance time, scattered convection had redeveloped over the last hour from KLCH to KBTR. This may be firing on lake/sea breeze boundaries, if radar and satellite imagery is any indication. Convection allowing models hold on to this convection until somewhere in the 03z-05z time frame. Carrying VCTS right now in the KBTR forecast, but it won't take much more northward development to necessitate an amendment for direct impacts. Once the evening convection dies out, VFR conditions should predominate until right around sunrise, when marine convection moves inland. Tomorrow is going to look a lot like today with scattered SHRA/TSRA developing by mid-morning, then dissipating around sunset. && .MARINE... Issued at 215 PM CDT Sat Jul 20 2024 Light onshore flow continues for the coastal waters for the whole forecast period. Only concerns will be higher winds and waves in and near thunderstorms and the possibility of waterspouts, especially in the morning hours. && .PRELIMINARY POINT TEMPS/POPS...
