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.

Cold front has moved through about the northern third of OK, with surface temperatures in the lower/mid 30s near the KS border. Based on recent HRRR/NAM output, going Winter Weather Advisory looks to be in good shape. Some very light freezing rain/drizzle may develop late tonight, although best chances look to hold off until after 6-7 am. The northern half of the advisory, mainly from Osage county east to Ottawa county, looks to be the favored area for accumulating freezing rain/sleet Friday morning and into the afternoon before precip tapers off.
