Fall Season Departures

Posted:

The weekly update to the US Drought Monitor is due to be released later this morning and likely not show much in the way of improvement to the worsening drought situation for the state. The featured map presents IEM computed precipitation departures from average since the first of September. Only a few isolated areas are indicated to be above average with large departures dominating the rest of the state. The drought situation is difficult to analyze outside of the growing season, which is during a time of year with decreased water demands but also decreased climatologies. Rewording, it is difficult to significantly increase deficits when climatology decreases with each passing day and metrics like 90 day precipitation departures will organically improve just by attrition. It would certainly be nice to get a few big rain events prior to colder temperatures and having the ground surface freeze, but the near term forecast doesn't hold much hope for that happening.
