Recent rains have helped to dent our drought and cause area lakes to rise.  Even though the La Niña weather pattern continues, we've seen quite a few drenching downpours since November.  The above graph shows over 4" in each of the last three months, a trend that has us moving in the right direction. 

Each week, the National Weather Service puts out a drought monitor.  The levels of drought range as follows: dry, moderate, severe, extreme and exceptional.  Last fall, our drought reached its worse stage as ALL of southeast Texas was classified as being under an exceptional drought, the highest level of drought:

In each of the last three months, it's only rained an average of 5 days per month.  That doesn't seem like a lot, but each time it has rained, we've had substantial amounts.  Here's what the drought monitor looks like at the end of January:

The deep, dark red areas have turned brown.  In other words, the exceptional drought has been reduced to severe drought over parts of southeast Texas.  There are still quite a few counties whose drought level remains classified as exceptional and extreme, but it is a step in the right direction.  Our next rain chance comes in the middle of next week.
