EDIT: Enhanced version in comments.

The National Weather Service API is complex and byzantine in my experience, so I made this python script to parse their tabular hourly forecasts which meets my needs for machine readable immediate wind and rain forecast data:

import re
import requests

html = requests.get(
  'https://forecast.weather.gov/MapClick.php?lat=21.3069&lon=-157.8583&unit=0&lg=english&FcstType=digital'
  ).text
html = next(line for line in html.splitlines() if "<b>Date" in line)

regex_suffix = '.*?<b>([^<]+)</b>' * 2 # up to 24 data; 48 with the other "<b>Date" line
hour_current, hour_upcoming = re.search(f"Hour{regex_suffix}", html).groups()
temp_current, temp_upcoming = re.search(f"Temperature{regex_suffix}", html).groups()
dir_current, dir_upcoming = re.search(f"Wind Dir{regex_suffix}", html).groups()
wind_current, wind_upcoming = re.search(f"Surface Wind{regex_suffix}", html).groups()
precip_current, precip_upcoming = re.search(f"Precipitation{regex_suffix}", html).groups()

print("Current hour:", int(hour_current))
print("  Wind direction:", dir_current)
print("  Wind speed:", wind_current, "mph")
print("  Temperature:", temp_current, "°F")
print("  Precipitation potential:", precip_current, "%")
print("Upcoming hour:", int(hour_upcoming))
print("  Wind direction:", dir_upcoming)
print("  Wind speed:", wind_upcoming, "mph")
print("  Temperature:", temp_upcoming, "°F")
print("  Precipitation potential:", precip_upcoming, "%")

Change the "lat=21.3069&lon=-157.8583" parameters for your location of interest. Example output:

Current hour: 6
  Wind direction: ENE
  Wind speed: 16 mph
  Temperature: 75 °F
  Precipitation potential: 13 %
Upcoming hour: 7
  Wind direction: ENE
  Wind speed: 16 mph
  Temperature: 75 °F
  Precipitation potential: 13 %
