Cold Winds but Not Much Rain


The intrusion of a strong cold front from New Mexico into southeastern Arionza around 4 am this morning brought an end to the precipitation at lower elevations in eastern Pima County. Strong downslope east winds continue here at the house with gusts estimated 30 to 35 mph. For the 24 hours ending at 7 am 90% of the Pima County alert gauges had measured rain but, even though the event was widespread, amounts were light with the highest amount only 0.47". Here at the house the entire, even with several periods of lightning and thunder, event produced only 0.10". Earlier this morning the strong east winds across the Rincon Mountains produced a sky that reminded me of Colorado - lenticular clouds, a cap cloud sitting on the mountains and a couple of rotor clouds to the west of the mountains. Regardless of the sad amounts of rain, it's nice to have some weather again after so long.
