Southwest Colorado is going backwards on the drought map
Tuesday – 1 Aug 2023 – 3:00pm
The average high for July is 83 – our warmest month – and the average low is 44. The record high of 99 occurred on 7 July 1989. The record low of 24 occurred on 5 July 1912. Precip averages 2.01″ in July. Wolf Creek Pass averages 3.61″ of rain and zero snow.
How did we do?
Drought, River Flow, and Lake Levels…
The average high for August is 80 and the average low is 45. The record high of 97 occurred on 5 August 1940. The record low of 28 occurred on 30 August 1978. Precip averages 2.69″ in August – our wettest month. Wolf Creek Pass averages 4.32″ of rain and zero snow.
And what do we expect?
Arleen is the expert, and this is what she expects…
The first two weeks of August the dry trend will continue. The subtropical ridge is going to be sumo wrestling with the polar front jet and an upper level trough that makes it way across the CONUS during the first 10 days of the month. Unfortunately for us, the subtropical ridge will lose.
By the 10th the trough will be centered from Minnesota to the southern plains, exactly where we want the subtropical ridge to be for ideal monsoon moisture. However, it’s inverted from what we want. As we saw in July, this is most likely due to the El Nino influence resulting in a dry zonal flow from west to east.
Around the 10th, the ridge starts to rebuild, centered over Colorado. It will take a few days to rebuild and a few days for the moisture to advect into the area but we’ll end the month with an increase of moisture.
In spite of ending the month with a cooling trend and a bit more moisture, I expect less than average precip for August and temperatures to be warmer than average.
