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.

.DISCUSSION...
Northwest winds 10 mph or less through the day will gradually
decrease and veer north-northeasterly by sunset. Rain chances are
elevated today (around 60%), focused primarily after 4-6 PM. A
lightning storm and briefly heavy rainfall cannot be ruled out at
the burn location. As for fog potential overnight, modeled
ensemble (HREF) probabilities are less than 5% for visibility
under one mile across western Martin County. However, with light
winds in place, settling smoke is a possibility, which could lead
to localized visibility reductions. In addition, if any heavy
rainfall occurs around the burn site, the potential for locally
patchy ground fog would increase.
