.DISCUSSION...Tonight through Saturday...Isolated to scattered
showers and thunderstorms to bring brief heavy rain and gusty
winds up to 50 mph through this evening. Moisture increases for
Tuesday through Thursday with scattered to numerous showers and
thunderstorms each afternoon and evening. Due to weak winds aloft
thunderstorm movement will be slow resulting in a heavy rain
threat. We turn hotter and drier Friday and through the weekend as
high pressure aloft builds over the Central Rockies.
...Thunderstorms imply strong gusty erratic winds...
...All surface winds are 20-Foot...10-Minute averaged winds...
...CWR is Chance of Wetting Rain - 0.10 inch or more liquid...
...24 HR Trends are based on averages over the respective zone
