With precipitation levels running below normal for four of the first five months, 2017 can hardly be characterized as wet. However, there is a distinct difference in overall moisture levels so far this year between the mainland parts of the County, Galveston Island and areas near the coast.
Since January 1, League City/Dickinson has received 14.60” of rain (mostly due to some heavy rains in April). This is only slightly below what would be expected through May 10 at that location. Galveston, on the other hand, has officially measured only 7.14” of rain so far this year. This is only about half of what would be expected at present. Needless to say, the southern part of the County really needs some decent precipitation before heat and evaporation levels begin to really dry out the soil.
The good news is that there will be a chance for rain from tonight through Friday, as an upper-level system tracks into Oklahoma and a weak cold front moves slowly to the coast. The bad news is that most models suggest that rain amounts again will likely be meagre and do little to improve dry conditions in the southern part of the County.
Looking further down the road, there is at least some hope for improvement as we move into mid-May and beyond. After repeatedly projecting dry conditions the intermediate models have started to portray somewhat wetter conditions a week to two weeks from now. If the system currently headed our direction fails to provide much relief as expected, then we will certainly need some wet weather as we move deeper into May!
