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.

The headline for fire weather concerns highlights critical fire weather conditions developing Sunday, as a cold front moves into West Central Texas, from the west. We have canceled the Fire Weather Watch and issued a Red Flag Warning. The Red Flag Warning will begin at 11 AM Sunday morning and continue until 7 PM Sunday evening. It's during that time frame when winds will be highest and relative humidity will be lowest. Winds at 20 feet above ground level, will be from the west, at 20 to 25 mph, with possible gusts in the 35 to 40 mph range. For those counties in the warning, critical fire weather conditions are likely. For those counties not in the warning, fire weather concerns will be near critical, as 20 foot winds, from the west, should remain below 20 mph. && .PRELIMINARY POINT TEMPS/POPS...
