Very dry conditions will persist with warmer temperatures today. Humidity will drop into the single digits across the plains during the afternoon, with only moderate recovery tonight.

Unseasonably warm and dry weather continues into Tuesday, with single digit humidity on the plains again. Winds will still be relatively light Tuesday, although south to southeast breezes will increase a little by Tuesday afternoon. Critical fire weather conditions are likely to develop Wednesday, as southwest winds increase in an unseasonably warm and dry airmass.

Humidity levels will drop into the 7-11% range over most of the plains, with minimum RH under 15% in most of the foothills and high mountain valleys. Those critical conditions may last well into Wednesday evening with a continuation of strong, gusty winds. Cooler temperatures will arrive for Thursday, but it will still remain dry and breezy (windy northeast plains) with another day of elevated to critical conditions expected. Cooler and more moist air arrives for Friday and the weekend with a daily chance of showers. ...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 groups and may not match the actual forecast values shown in those groups...
