The dry season is entering its cold phase.
That means evapotranspiration (ET) will be seasonally shutting down for the next three months.
From a water cycle perspective, even without any rain the water table only drops very slowly as a result. It isn't until March, April and May that ET starts to crank back up. When that happens we will desperately depend on frontal rain showers to keep the water table from precipitously dropping down into deep drought.
As for now, a little rain goes a long way in cool winter months.
